A. Introduction
1. The Appellant, Protus Wamocha Mungasa, was charged before the Chief Magistrate's Court at Bungoma with the offence of defilement contrary to section 8(1) as read with section 8(3) of the Sexual Offences Act No. 3 of 2006, the particulars being that on 23rd February 2018 at Lukhome area, Bungoma Central Sub-County, he unlawfully and intentionally caused his penis to penetrate the vagina of V.N.B., a child then aged 13 years. In the alternative, he faced a charge of committing an indecent act with a child contrary to section 11(1) of the same Act. He also faced a second count of interference with a witness contrary to section 117(b) of the Penal Code, it being alleged that between April 2019 and 25th November 2019 he facilitated the removal of the complainant to Matasia, Ngong, so as to obstruct her from testifying.
2. The Appellant pleaded not guilty to all counts. The trial, commenced before Hon. J. King'ori (CM), traversed the Courts of four different magistrates between 2019 and 2024 owing to transfers and part-heard status, before Hon. C.M. Maundu (CM), applying section 200(3) of the Criminal Procedure Code with the Appellant's consent to proceed from where the matter had reached, delivered judgment on 17th October 2024. The Appellant was convicted on both counts and sentenced to twenty (20) years' imprisonment on count one (the statutory minimum under section 8(3)) and one (1) year on count two, the sentences to run concurrently.
3. Aggrieved, the Appellant filed a Petition of Appeal and, upon instructing counsel, Supplementary Grounds of Appeal dated 2nd April 2025. The grounds, taken together, may be consolidated as follows:
(i) That the Appellant did not plead guilty;
(ii) That the conviction rests on contradictory, inconsistent and uncorroborated evidence;
(iii) That the trial Court failed to observe the forensic procedure under section 36 of the Sexual Offences Act, and that the case was not proved beyond reasonable doubt in the absence of DNA evidence;
(iv) That the complainant was not subjected to a voir dire examination before giving sworn evidence;
(v) That the trial Court disregarded or misapplied the evidence of the clinical officer (PW5);
(vi) That the trial Court failed to consider contradictory oral evidence, including the delay in reporting and the circumstances of the complainant's departure to Nairobi;
(vii) That the trial Court failed to appreciate discrepancies concerning the complainant's age.
B. The Duty of this Court as a First Appellate Court
4. This being a first appeal, this Court is guided by the well-settled principles in Okeno v Republic [1972] EA 32, namely that an Appellant on first appeal is entitled to have the whole evidence subjected to fresh and exhaustive scrutiny, and that this Court must re-evaluate the evidence and reach its own independent conclusions, while making due allowance for the fact that it neither saw nor heard the witnesses testify, an advantage that remained with the trial Court alone.
5. I have accordingly re-read the entire record — the charge sheet, the proceedings before all four magistrates, the ruling on the prima facie case, the judgment, and the exhibits — before arriving at the findings below. It is convenient first to summarise the evidence of each witnesses.
C. Summary of the Evidence
Prosecution's Case
6. PW1 — Vivian Nekesa Bwake (the complainant). Sworn evidence, taken on 13th January 2020. She testified that she was born on 18th August 2005 and produced her birth certificate (later P Exh-1). She knew the Appellant well before the incident as a neighbour and a barber operating at Lukhome market. She testified that on 23rd February 2018, at about 6.00 a.m., while walking to Lukhome Secondary School, she met the Appellant standing by the roadside near his house; he stretched out his hand to greet her, then pulled her by the hand into his house, warned her not to scream, undressed her, and defiled her, gagging her mouth in the process. She felt pain and, on his instruction, proceeded to school without telling anyone. She stated that she persevered the pain and did not disclose the incident to her mother until 2nd April 2018, whereupon she was taken to Chwele Police Station and then to hospital for examination.
7. She further testified that, while the case was pending, the Appellant approached her, gave her a wristwatch and a kikoi as gifts, and persuaded her to relocate to Nairobi to stay with his cousin "Belinda" in Matasia, Ngong, telling her this would end the case. She travelled there by matatu, assisted by a boda boda rider who collected her belongings, and remained in Nairobi for approximately eight months, during which the Appellant maintained contact and periodically sent her small sums of money through his cousin's phone, until he stopped doing so around September 2019.
8. She testified that the Appellant's father later telephoned her, through Belinda, stating that the case had ended and that he would sue her father for damages; she then contacted her own father, who sent her bus fare, and she returned home on 26th November 2019, whereupon the matter was reported afresh and the Appellant re-arrested. In cross-examination, she conceded some uncertainty as to dates (correcting an initial reference to "23/3/18" to "23/2/18"), confirmed she had not bled and that this was her first sexual experience, she further stated that she was tested for pregnancy, HIV and sexually transmitted disease, was not found pregnant or HIV-positive but stated she was with an STD, of which she was not told which one, and confirmed that a prior disappearance from home, unrelated to the Appellant, had been at her parents' own direction to stay with an aunt.
9. PW2 — Annet Machuma (Masika) (the complainant's mother). Gave sworn evidence on 12th November 2020. She testified that she is a farmer residing at Luhome market, she confirmed her daughter's date of birth and testified that on 2nd April 2018 the complainant disclosed that the Appellant had disturbed her on her way to school on previous occasions and had, on 23rd February 2018, taken her into his house and had sexual intercourse with her. She testified that she confronted the Appellant, who remained silent, and that on 3rd April 2018 the complainant came home with a wristwatch and a Maasai kikoi, which she said the Appellant had given her; PW2 confiscated these items (later produced as P Exh-8 and P Exh-9).
10. She reported the matter to Luhome police post on 4th April 2018, escorted the complainant for medical examination, obtained a P3 form, and confirmed the Appellant's subsequent arrest and charge. She further testified that on 5th April 2019 she found her daughter missing from home, reported the disappearance on 6th April 2019, and suspected the Appellant's involvement. She received a call from the complainant on 24th November 2019 who informed her that she was at Matasia, Ngong and requested for bus fare, which her husband sent. The further told the Court that the complainant return on 26th November 2019 where a further police report and medical examination was conducted on the complainant on 27th November 2019. She stated she held no grudge against the Appellant. In cross-examination, she confirmed the dates given, stated she was not told why the hospital had administered drugs to her daughter, and that the complainant told her she had stayed with the Appellant in Matasia for three days before being left in the care of his cousin, Penina.
8. PW3 — Alfred Bwake Kituyi (the complainant's father). He gave sworn evidence on 19th May 2021. He testified that he is a caretaker with Gigiri Data Centre residing in Nairobi, and he confirmed that the complainant was his first-born child and that he knew the Appellant as a neighbour. He testified that on 6th April 2019, while at work in Nairobi, his wife (PW2) called to inform him that the complainant was missing; he testified that the complainant had been a witness in a pending defilement case which had by then been withdrawn for want of the complainant's attendance. He testified that on 24th November 2019 he received a call from the complainant, who told him that she was in Ngong and needed bus fare. He testified that he did not send the money that night, but sent Kshs. 1,529 together with a further Kshs. 250 following day, 25th November 2019, to the owner of the phone the complainant was using. The complainant arrived home on 26th November 2019, and the family reported her reappearance to Chwele police on 27th November 2019. He testified that the complainant was again taken for medical examination. He stated he held no grudge against the Appellant. In cross-examination, he stated he had sent the fare via the phone of one Dominic Muema, whom he described as a good Samaritan he had never met, and that he did not personally visit the Ngong residence where the complainant had been staying.
11. PW4 — Inspector Sarah Situma (Investigating Officer). Gave sworn evidence on 12th September 2022. She said she was attached to Saboti Police Station and testified that she took over the investigation from Chief Inspector Ndiwa, who had retired, after the original charge (Sexual Offence No. 62 of 2018) had been withdrawn under section 87(a) of the Criminal Procedure Code when the complainant could not be traced. She testified that a report of defilement was first made at Chwele Police Station on 5th April 2018c. She interrogated the complainant on 2nd December 2019 following her reappearance, and that the complainant recounted being defiled by the Appellant on 23rd February 2018 and being induced with gifts of a wristwatch and shawl, later relocated by the Appellant to his sister's home in Ngong/Matasia to avoid testifying.
12. She testified that the Appellant's father had threatened to sue the complainant's family, prompting the complainant's return, and that fresh charges were then preferred. She produced the wristwatch (P Exh-8) and kikoi/shawl (P Exh-9) as exhibits and confirmed the complainant's in-Court identification of the Appellant. In cross-examination, she conceded that although the offence was reported on 5th April 2018, the Appellant was not arrested until 13th July 2018, and she could not tell why it took time. She testified that she did not visit the scene of the alleged offence and that she did not know whether the Appellant had infected the complainant with any sexually transmitted infection and confirmed the Appellant was never examined for one; and that it was the complainant herself who had told the investigators about the wristwatch and shawl.
13. PW5 — John Weremba (Clinical Officer). Testified that he is a clinical officer attached to Webuye Sub-County Hospital, previously based at Chwele Sub-County Hospital, he testified to having examined the complainant in connection with the alleged defilement of 23rd February 2018, he testified that he recorded that there were no lacerations or discharge on examination, that all laboratory tests conducted were negative, and that medication was administered. He confirmed the complainant's age was recorded as thirteen years. He produced the outpatient cards of 4th April 2018 (P Exh-2), 5th April 2018 (P Exh-6), and 27th November 2019 (P Exh-11), together with the age assessment form and the P3 form (P Exh-7). In cross-examination, he confirmed he examined the complainant roughly a month and a half after the alleged incident, that the examination was negative, that he did not examine the Appellant, that he could not comment on penetration, and that the condition of the hymen was not noted in his findings.
Defence Case
14. DW1 — The Appellant (sworn evidence). The Appellant elected to give sworn evidence and called one witness. He denied committing the offence. He testified that the complainant's mother had brought her mobile phone to his barber shop for charging, that a power outage occurred and the phone was damaged, and that she then demanded he pay for the damaged phone. He denied ever buying the complainant any gifts or arranging her relocation to Nairobi. In cross-examination, he stated he knew the complainant but had no relationship with her and he did not wait for her on the road as she went to school. He testified that he did not know a person called Belinda and that Belinda was not his sister; he stated the complainant's father lived in Nairobi and that she had gone to live with him. The Appellant maintained that he had been falsely implicated. In re-examination, he denied ever having any affair with the complainant and denied arranging for her to run away from home.
15. DW2 — John Wamoja (the Appellant's brother). He testified that he resided in the Luhome area and had recently completed college, and was the Appellant's brother, sharing the same house and the same bed with him. He testified that on the night of 23rd February 2018 he slept in the same bed as the Appellant, that he never saw the complainant with the Appellant, and that he was not aware of any relationship between them. In cross-examination, he confirmed he was the Appellant's brother and that the Appellant had three children and had remarried. He conceded that the alleged incident was said to have occurred at around 6.00 a.m., when the Appellant customarily woke early for work, while the witness himself did not work and, by clear implication, could not personally vouch for the Appellant's whereabouts at that specific hour. He further conceded, when pressed, that defilement is generally committed secretly and not openly.
16. The defence closed its case on 3rd July 2024 and the matter proceeded to submissions and judgment.
D. The Judgment of the Trial Court
17. In its judgment delivered on 17th October 2024, the trial Court framed a single, well-focused issue for determination: whether the offence of defilement had been proved to the required standard. It correctly directed itself, citing the three recognised ingredients of the offence; the age of the victim, penetration, and the identification of the perpetrator and proceeded to consider each in turn before addressing the second count.
18. On age, the trial Court held that the prosecution's production of the complainant's certificate of birth, indicating a date of birth of 18th August 2005, coupled with her own testimony, sufficed to establish that she was "approximately 13 years old" as at the date of the offence, which the judgment itself records as 23rd March 2018, a date that does not accord with the charge sheet or the unanimous evidence of every witness who spoke to it, all of whom fixed the date at 23rd February 2018. The trial Court did not remark upon this internal inconsistency, but nonetheless concluded that the first ingredient had been adequately proven.
19. On penetration, the trial Court held that this was proved through the evidence of the victim corroborated by medical evidence, noting the complainant's detailed narration of the assault and her evidence of persistent genital pain. The trial magistrate expressly acknowledged that the clinical officer who completed the P3 form "failed to indicate whether the complainant's hymen was intact or broken," but held that this omission did not defeat the charge, concluding that the complainant's evidence was "sufficient to prove penetration."
20. On identification, the trial Court held that the complainant knew the Appellant very well as a neighbour, that he was not a stranger, and that she was accordingly able to recognise him as the perpetrator. The Court treated this ingredient as undisputed on the evidence.
21. Having so found, the trial Court held that the charge of defilement was adequately proved by the Prosecution to the required threshold and convicted the Appellant on count one under section 215 of the Criminal Procedure Code.
22. On count two, the trial Court held, in emphatic terms, that there was "no doubt in my mind" that the Appellant had relocated the complainant to Nairobi in order to stop her from testifying in the earlier case (Sexual Offence No. 62 of 2018), that the said case was consequently withdrawn under section 87(a) of the Criminal Procedure Code, and that the evidence against the accused is overwhelming. The trial magistrate convicted the Appellant on count two on the same statutory basis.
23. On sentence, the trial Court correctly directed itself that the penalty under section 8(3) of the Sexual Offences Act is mandatory and that it retained no sentencing discretion in respect of count one, notwithstanding the mitigation advanced on the Appellant's behalf (that he was a first offender, aged 34, the sole breadwinner for a young family, and responsible for an elderly and ailing mother). It imposed the statutory minimum of twenty years' imprisonment on count one and one year's imprisonment on count two, directing that the sentences run concurrently.
24. I note that the trial Court's judgment does not anywhere address the absence of a recorded voir dire examination, the delay in reporting, or the sexually transmitted infection evidence referred to by the complainant in cross-examination. This is unsurprising, as none of these matters appears to have been raised as a distinct issue before the trial Court; they arise for the first time as grounds of appeal, and I address them as such below, after first testing the trial Court's core findings on the three ingredients against the record.
E. Issues for Determination
25. Having considered the grounds of appeal and the rival submissions, I am satisfied that the appeal turns on the following issues:
Whether the Ingredients of Defilement Were Proved
26. The offence of defilement under section 8(1) of the Sexual Offences Act requires proof of three ingredients: (i) the age of the complainant, (ii) penetration, and (iii) the identity of the perpetrator. This was well highlighted in the case of George Opondo Olunga v Republic [2016] eKLR).
(i) Age
27. PW1 testified that she was born on 18th August 2005. PW2, her mother corroborated this, and a certified copy of the birth certificate was produced as P Exh-1. On the date of the alleged offence, 23rd February 2018, the complainant was in fact twelve (12) years and slightly over six (6) months old, not thirteen years as recited in the charge sheet, the P3 form and the trial Court's judgment. I note this discrepancy for accuracy, but it is immaterial to the outcome: whether the complainant was twelve or thirteen years old, she falls squarely within the twelve-to-fifteen-year bracket contemplated by section 8(3) of the Act, which attracts the identical mandatory minimum sentence of twenty years. Age was, in any event, credibly established by the concurrent evidence of the birth certificate and the complainant's mother, which is precisely the mode of proof endorsed in Francis Omuroni v Uganda, Court of Appeal Criminal Appeal No. 2 of 2000, and adopted in this jurisdiction in Edwin Nyambogo Onsongo v Republic [2016] eKLR; Richard Wahome Chege v Republic [2014] eKLR), namely that age may be proved by birth certificate, parental testimony, medical evidence, or a combination thereof, and need not rest on medical evidence alone. I find that the first ingredient was proved.
(ii) Identification
28. PW1's evidence, corroborated by PW2, was that she knew the Appellant well before the incident as a neighbour and a barber operating at Lukhome trading centre. She named him and identified him in the dock. This is a case of recognition rather than fleeting identification, and recognition of a person well known to a witness is inherently more reliable than identification of a stranger. The long-settled distinction applied in Kenyan authority since Anjononi v Republic [1980] KLR 59, applied consistently in defilement cases. This ingredient was proved.
(iii) Penetration
29. PW1 gave a clear, sequential account of being pulled into the Appellant's house, undressed, and penetrated, and of the pain she thereafter experienced. It is correct, as the Appellant submits, that PW5, the clinical officer who examined her and completed the P3 form, did not record a finding on the state of the hymen and did not himself speak to penetration.
30. This omission is not fatal. It is now firmly settled in this jurisdiction that medical evidence, while desirable, is not a mandatory requirement for a conviction of defilement, and that the direct and cogent testimony of the complainant, properly tested, may suffice, particularly where corroborated by evidence of physical complaint such as pain as was decided in the case of Kaingu Elias Kasomo v Republic, Mombasa Criminal Appeal No. 504 of 2010, cited in Martin Nyongesa Wanyonyi v Republic [2015] eKLR: that medical evidence is not the only evidence by which commission of a sexual offence may be proved; and George Hezron Mwakio v Republic [2010] eKLR). Moreover, under section 2 of the Sexual Offences Act, the "slightest" penetration suffices to constitute the offence, and rupture of the hymen is not a necessary finding. I place reliance on the case of Twehangane Alfred v Uganda, Criminal Appeal No. 139 of 2001, cited by the Court of Appeal in Kenyan defilement jurisprudence. I am satisfied that the trial Court did not err in relying on the complainant's own account, read together with her contemporaneous complaint of genital pain, to find penetration proved.
E. The Voir Dire Ground
31. Counsel for the Appellant submits, correctly on the face of the record, that no voir dire examination is recorded before PW1 gave sworn evidence on 13th January 2020. The authorities relied upon, including MAM v Republic and the Kisumu Court of Appeal decision cited, correctly state the general principle that a child of tender years must be shown, through a recorded voir dire, to understand the nature of an oath before her sworn evidence can safely found a conviction.
32. The difficulty for the Appellant is that the threshold for what constitutes a "child of tender years" for this specific purpose has been authoritatively settled in this jurisdiction at under fourteen years, following Kibangeny Arap Kolil v Republic [1959] EA 92, and reaffirmed in numerous subsequent decisions (see Samson Oginga Ayieyo v Republic, Kisumu Criminal Appeal No. 165 of 2006; DNN v Republic [2021] eKLR, where the High Court confirmed that "the time-honoured 14 years remains the correct threshold for voir dire examination"). Where a witness has already attained fourteen years, our Courts have held a voir dire to be unnecessary (see MK v Republic [2015] eKLR, where the Court of Appeal termed voir dire "unnecessary" for a witness aged fifteen).
33. On the record before me, PW1 was born on 18th August 2005 and testified on 13th January 2020, by which date she was fourteen years and almost five months old — a fact confirmed by the prosecutor's own statement on record that "the complainant is 14 years old and will give sworn evidence." She had, therefore, already passed the threshold at which a voir dire examination is treated as obligatory. While it remains good and prudent practice for a trial Court to satisfy itself, even informally, that any young witness understands the nature of an oath, the absence of a recorded voir dire in respect of a witness who was no longer within the "tender years" bracket does not, without more, render her sworn evidence inadmissible or unsafe. I note further that experienced defence counsel was present throughout PW1's testimony and raised no objection at the time to the taking of her evidence on oath, which is a further indicator that no prejudice arose. This ground fails.
F. The Delay in Reporting
34. This is a matter to which I have given close and particular attention, as it bears directly on the credibility of the complainant.
35. Two distinct periods of delay appear on the record, and it is important to keep them separate, as they raise different considerations.
(i) The complainant's own delay in disclosing the assault
36. The offence is alleged to have occurred on 23rd February 2018. PW1's own evidence, corroborated by PW2 and PW3, is that she did not tell anyone until she confided in her mother on 2nd April 2018 — an interval of approximately five and a half to six weeks. The matter was then reported to the police and the complainant medically examined on 4th and 5th April 2018.
37. I do not find this interval, in the circumstances of this case, to cast reasonable doubt on the complainant's account. PW1 explained that the Appellant warned her not to disclose the incident, that she was in continuing pain, and that she ultimately spoke out only when the pain became unbearable. This is an entirely credible account of a child's reaction to sexual violation by a person known to and in a position of informal authority over her (an adult neighbour who ran the barber shop she frequented).
38. Courts have consistently recognised that children who are victims of sexual abuse commonly delay disclosure out of fear, shame, confusion, or a threat by the perpetrator, and that such delay, without more, does not undermine the child's credibility. In Muganga Chilejo Saha v Republic [2017] eKLR the Court of Appeal observed that child victims of sexual abuse are often devastated by the experience and, given their innocence, may feel too ashamed or afraid to speak of it, including before a Court. This reasoning was applied by the High Court in Okoko v Republic [2022] eKLR to hold that a delay explained by the child's fear of disclosure was not "inordinate" and did not defeat the prosecution's case. I respectfully adopt the same approach here. A delay of some five to six weeks, explained by fear following an explicit threat and by the child's own attempt to bear the resulting pain in silence, is neither inordinate nor unusual, and does not by itself generate reasonable doubt as to whether the offence occurred.
39. I have also considered the countervailing line of authority relied upon in cases such as Waita Munyoki v Republic [2018] eKLR, where a delay in naming the assailant, combined with an absence of any evidence directly linking the accused to the offence and evidence of an existing grudge, was found to raise reasonable doubt. That case is distinguishable: here, there is no suggestion of a grudge, the complainant named the Appellant consistently and immediately upon disclosure, and her identification of him is not in issue. The delay here goes only to the timing of disclosure of an offence whose perpetrator was never in doubt, which is a materially different scenario from delayed or inconsistent identification.
(ii) The delay in arrest following the police report
40. A second, distinct period of delay appears in the evidence of PW4, who candidly admitted in cross-examination that although the offence was reported to police on 5th April 2018, the Appellant was not arrested until 13th July 2018 — an unexplained interval of just over three months, which PW4 could not account for when she stated "I cannot tell why it took time"). This is properly characterised as an investigative delay rather than a delay attributable to the complainant, and it does not reflect on her credibility at all. It is, at most, a legitimate criticism of the diligence of the police investigation. However, an unexplained delay in effecting an arrest, without evidence that it caused any specific prejudice to the Appellant's ability to mount his defence and no such prejudice has been demonstrated or even asserted, does not, on its own, vitiate an otherwise properly proved charge. I find nothing on this score that assists the Appellant.
41. I am accordingly satisfied that neither limb of delay identified in the record, whether considered individually or cumulatively, creates reasonable doubt as to the Appellant's guilt.
G. The Sexually Transmitted Infection Evidence
42. Counsel for the Appellant places considerable weight on the suggestion that the complainant was found, some months after the alleged incident, to have contracted a sexually transmitted infection, said to be syphilis, and argues that the failure to test the Appellant for the same infection is a fatal gap in the prosecution's case, drawing an analogy with cases such as Kevin Moriasi Ondieki v Republic [2020] eKLR, where a documented finding that the complainant had contracted syphilis, combined with medical evidence that the accused tested negative for the same infection, contributed to the quashing of a conviction.
43. Having examined the actual medical exhibits on this record with care, I do not find that analogy to hold. The only evidence of an infection at all is PW1's own answer in cross-examination that she "was not found with HIV but was with an STD," of which she was "not told which one." This assertion is not corroborated, and indeed is contradicted, by the documentary medical evidence before the Court. The treatment card produced as MFI 10/P Exh-11, arising from her examination on 27th November 2019, records a non-reactive PITC (HIV) result and, critically, a negative VDRL — VDRL being the standard serological screening test for syphilis. The P3 form (P Exh-7) completed following her earlier examination in April 2018 likewise does not record a positive finding for any venereal infection; if anything, the examining officer's notes record the absence of abnormal discharge. There is, in short, no positive laboratory finding of syphilis, or of any sexually transmitted infection, anywhere in the documentary record. The suggestion that the complainant tested positive for syphilis does not find support in the exhibits and appears to rest on a misreading of, or an overstatement of the record.
44. This distinguishes the present case sharply from Kevin Moriasi Ondieki, where the quashing of the conviction rested in material part on a documented positive finding in the complainant set against a documented negative finding in the accused, a combination which, taken with other doubts in that recor
[...truncated]
1. The Appellant, Protus Wamocha Mungasa, was charged before the Chief Magistrate's Court at Bungoma with the offence of defilement contrary to section 8(1) as read with section 8(3) of the Sexual Offences Act No. 3 of 2006, the particulars being that on 23rd February 2018 at Lukhome area, Bungoma Central Sub-County, he unlawfully and intentionally caused his penis to penetrate the vagina of V.N.B., a child then aged 13 years. In the alternative, he faced a charge of committing an indecent act with a child contrary to section 11(1) of the same Act. He also faced a second count of interference with a witness contrary to section 117(b) of the Penal Code, it being alleged that between April 2019 and 25th November 2019 he facilitated the removal of the complainant to Matasia, Ngong, so as to obstruct her from testifying.
2. The Appellant pleaded not guilty to all counts. The trial, commenced before Hon. J. King'ori (CM), traversed the Courts of four different magistrates between 2019 and 2024 owing to transfers and part-heard status, before Hon. C.M. Maundu (CM), applying section 200(3) of the Criminal Procedure Code with the Appellant's consent to proceed from where the matter had reached, delivered judgment on 17th October 2024. The Appellant was convicted on both counts and sentenced to twenty (20) years' imprisonment on count one (the statutory minimum under section 8(3)) and one (1) year on count two, the sentences to run concurrently.
3. Aggrieved, the Appellant filed a Petition of Appeal and, upon instructing counsel, Supplementary Grounds of Appeal dated 2nd April 2025. The grounds, taken together, may be consolidated as follows:
(i) That the Appellant did not plead guilty;
(ii) That the conviction rests on contradictory, inconsistent and uncorroborated evidence;
(iii) That the trial Court failed to observe the forensic procedure under section 36 of the Sexual Offences Act, and that the case was not proved beyond reasonable doubt in the absence of DNA evidence;
(iv) That the complainant was not subjected to a voir dire examination before giving sworn evidence;
(v) That the trial Court disregarded or misapplied the evidence of the clinical officer (PW5);
(vi) That the trial Court failed to consider contradictory oral evidence, including the delay in reporting and the circumstances of the complainant's departure to Nairobi;
(vii) That the trial Court failed to appreciate discrepancies concerning the complainant's age.
B. The Duty of this Court as a First Appellate Court
4. This being a first appeal, this Court is guided by the well-settled principles in Okeno v Republic [1972] EA 32, namely that an Appellant on first appeal is entitled to have the whole evidence subjected to fresh and exhaustive scrutiny, and that this Court must re-evaluate the evidence and reach its own independent conclusions, while making due allowance for the fact that it neither saw nor heard the witnesses testify, an advantage that remained with the trial Court alone.
5. I have accordingly re-read the entire record — the charge sheet, the proceedings before all four magistrates, the ruling on the prima facie case, the judgment, and the exhibits — before arriving at the findings below. It is convenient first to summarise the evidence of each witnesses.
C. Summary of the Evidence
Prosecution's Case
6. PW1 — Vivian Nekesa Bwake (the complainant). Sworn evidence, taken on 13th January 2020. She testified that she was born on 18th August 2005 and produced her birth certificate (later P Exh-1). She knew the Appellant well before the incident as a neighbour and a barber operating at Lukhome market. She testified that on 23rd February 2018, at about 6.00 a.m., while walking to Lukhome Secondary School, she met the Appellant standing by the roadside near his house; he stretched out his hand to greet her, then pulled her by the hand into his house, warned her not to scream, undressed her, and defiled her, gagging her mouth in the process. She felt pain and, on his instruction, proceeded to school without telling anyone. She stated that she persevered the pain and did not disclose the incident to her mother until 2nd April 2018, whereupon she was taken to Chwele Police Station and then to hospital for examination.
7. She further testified that, while the case was pending, the Appellant approached her, gave her a wristwatch and a kikoi as gifts, and persuaded her to relocate to Nairobi to stay with his cousin "Belinda" in Matasia, Ngong, telling her this would end the case. She travelled there by matatu, assisted by a boda boda rider who collected her belongings, and remained in Nairobi for approximately eight months, during which the Appellant maintained contact and periodically sent her small sums of money through his cousin's phone, until he stopped doing so around September 2019.
8. She testified that the Appellant's father later telephoned her, through Belinda, stating that the case had ended and that he would sue her father for damages; she then contacted her own father, who sent her bus fare, and she returned home on 26th November 2019, whereupon the matter was reported afresh and the Appellant re-arrested. In cross-examination, she conceded some uncertainty as to dates (correcting an initial reference to "23/3/18" to "23/2/18"), confirmed she had not bled and that this was her first sexual experience, she further stated that she was tested for pregnancy, HIV and sexually transmitted disease, was not found pregnant or HIV-positive but stated she was with an STD, of which she was not told which one, and confirmed that a prior disappearance from home, unrelated to the Appellant, had been at her parents' own direction to stay with an aunt.
9. PW2 — Annet Machuma (Masika) (the complainant's mother). Gave sworn evidence on 12th November 2020. She testified that she is a farmer residing at Luhome market, she confirmed her daughter's date of birth and testified that on 2nd April 2018 the complainant disclosed that the Appellant had disturbed her on her way to school on previous occasions and had, on 23rd February 2018, taken her into his house and had sexual intercourse with her. She testified that she confronted the Appellant, who remained silent, and that on 3rd April 2018 the complainant came home with a wristwatch and a Maasai kikoi, which she said the Appellant had given her; PW2 confiscated these items (later produced as P Exh-8 and P Exh-9).
10. She reported the matter to Luhome police post on 4th April 2018, escorted the complainant for medical examination, obtained a P3 form, and confirmed the Appellant's subsequent arrest and charge. She further testified that on 5th April 2019 she found her daughter missing from home, reported the disappearance on 6th April 2019, and suspected the Appellant's involvement. She received a call from the complainant on 24th November 2019 who informed her that she was at Matasia, Ngong and requested for bus fare, which her husband sent. The further told the Court that the complainant return on 26th November 2019 where a further police report and medical examination was conducted on the complainant on 27th November 2019. She stated she held no grudge against the Appellant. In cross-examination, she confirmed the dates given, stated she was not told why the hospital had administered drugs to her daughter, and that the complainant told her she had stayed with the Appellant in Matasia for three days before being left in the care of his cousin, Penina.
8. PW3 — Alfred Bwake Kituyi (the complainant's father). He gave sworn evidence on 19th May 2021. He testified that he is a caretaker with Gigiri Data Centre residing in Nairobi, and he confirmed that the complainant was his first-born child and that he knew the Appellant as a neighbour. He testified that on 6th April 2019, while at work in Nairobi, his wife (PW2) called to inform him that the complainant was missing; he testified that the complainant had been a witness in a pending defilement case which had by then been withdrawn for want of the complainant's attendance. He testified that on 24th November 2019 he received a call from the complainant, who told him that she was in Ngong and needed bus fare. He testified that he did not send the money that night, but sent Kshs. 1,529 together with a further Kshs. 250 following day, 25th November 2019, to the owner of the phone the complainant was using. The complainant arrived home on 26th November 2019, and the family reported her reappearance to Chwele police on 27th November 2019. He testified that the complainant was again taken for medical examination. He stated he held no grudge against the Appellant. In cross-examination, he stated he had sent the fare via the phone of one Dominic Muema, whom he described as a good Samaritan he had never met, and that he did not personally visit the Ngong residence where the complainant had been staying.
11. PW4 — Inspector Sarah Situma (Investigating Officer). Gave sworn evidence on 12th September 2022. She said she was attached to Saboti Police Station and testified that she took over the investigation from Chief Inspector Ndiwa, who had retired, after the original charge (Sexual Offence No. 62 of 2018) had been withdrawn under section 87(a) of the Criminal Procedure Code when the complainant could not be traced. She testified that a report of defilement was first made at Chwele Police Station on 5th April 2018c. She interrogated the complainant on 2nd December 2019 following her reappearance, and that the complainant recounted being defiled by the Appellant on 23rd February 2018 and being induced with gifts of a wristwatch and shawl, later relocated by the Appellant to his sister's home in Ngong/Matasia to avoid testifying.
12. She testified that the Appellant's father had threatened to sue the complainant's family, prompting the complainant's return, and that fresh charges were then preferred. She produced the wristwatch (P Exh-8) and kikoi/shawl (P Exh-9) as exhibits and confirmed the complainant's in-Court identification of the Appellant. In cross-examination, she conceded that although the offence was reported on 5th April 2018, the Appellant was not arrested until 13th July 2018, and she could not tell why it took time. She testified that she did not visit the scene of the alleged offence and that she did not know whether the Appellant had infected the complainant with any sexually transmitted infection and confirmed the Appellant was never examined for one; and that it was the complainant herself who had told the investigators about the wristwatch and shawl.
13. PW5 — John Weremba (Clinical Officer). Testified that he is a clinical officer attached to Webuye Sub-County Hospital, previously based at Chwele Sub-County Hospital, he testified to having examined the complainant in connection with the alleged defilement of 23rd February 2018, he testified that he recorded that there were no lacerations or discharge on examination, that all laboratory tests conducted were negative, and that medication was administered. He confirmed the complainant's age was recorded as thirteen years. He produced the outpatient cards of 4th April 2018 (P Exh-2), 5th April 2018 (P Exh-6), and 27th November 2019 (P Exh-11), together with the age assessment form and the P3 form (P Exh-7). In cross-examination, he confirmed he examined the complainant roughly a month and a half after the alleged incident, that the examination was negative, that he did not examine the Appellant, that he could not comment on penetration, and that the condition of the hymen was not noted in his findings.
Defence Case
14. DW1 — The Appellant (sworn evidence). The Appellant elected to give sworn evidence and called one witness. He denied committing the offence. He testified that the complainant's mother had brought her mobile phone to his barber shop for charging, that a power outage occurred and the phone was damaged, and that she then demanded he pay for the damaged phone. He denied ever buying the complainant any gifts or arranging her relocation to Nairobi. In cross-examination, he stated he knew the complainant but had no relationship with her and he did not wait for her on the road as she went to school. He testified that he did not know a person called Belinda and that Belinda was not his sister; he stated the complainant's father lived in Nairobi and that she had gone to live with him. The Appellant maintained that he had been falsely implicated. In re-examination, he denied ever having any affair with the complainant and denied arranging for her to run away from home.
15. DW2 — John Wamoja (the Appellant's brother). He testified that he resided in the Luhome area and had recently completed college, and was the Appellant's brother, sharing the same house and the same bed with him. He testified that on the night of 23rd February 2018 he slept in the same bed as the Appellant, that he never saw the complainant with the Appellant, and that he was not aware of any relationship between them. In cross-examination, he confirmed he was the Appellant's brother and that the Appellant had three children and had remarried. He conceded that the alleged incident was said to have occurred at around 6.00 a.m., when the Appellant customarily woke early for work, while the witness himself did not work and, by clear implication, could not personally vouch for the Appellant's whereabouts at that specific hour. He further conceded, when pressed, that defilement is generally committed secretly and not openly.
16. The defence closed its case on 3rd July 2024 and the matter proceeded to submissions and judgment.
D. The Judgment of the Trial Court
17. In its judgment delivered on 17th October 2024, the trial Court framed a single, well-focused issue for determination: whether the offence of defilement had been proved to the required standard. It correctly directed itself, citing the three recognised ingredients of the offence; the age of the victim, penetration, and the identification of the perpetrator and proceeded to consider each in turn before addressing the second count.
18. On age, the trial Court held that the prosecution's production of the complainant's certificate of birth, indicating a date of birth of 18th August 2005, coupled with her own testimony, sufficed to establish that she was "approximately 13 years old" as at the date of the offence, which the judgment itself records as 23rd March 2018, a date that does not accord with the charge sheet or the unanimous evidence of every witness who spoke to it, all of whom fixed the date at 23rd February 2018. The trial Court did not remark upon this internal inconsistency, but nonetheless concluded that the first ingredient had been adequately proven.
19. On penetration, the trial Court held that this was proved through the evidence of the victim corroborated by medical evidence, noting the complainant's detailed narration of the assault and her evidence of persistent genital pain. The trial magistrate expressly acknowledged that the clinical officer who completed the P3 form "failed to indicate whether the complainant's hymen was intact or broken," but held that this omission did not defeat the charge, concluding that the complainant's evidence was "sufficient to prove penetration."
20. On identification, the trial Court held that the complainant knew the Appellant very well as a neighbour, that he was not a stranger, and that she was accordingly able to recognise him as the perpetrator. The Court treated this ingredient as undisputed on the evidence.
21. Having so found, the trial Court held that the charge of defilement was adequately proved by the Prosecution to the required threshold and convicted the Appellant on count one under section 215 of the Criminal Procedure Code.
22. On count two, the trial Court held, in emphatic terms, that there was "no doubt in my mind" that the Appellant had relocated the complainant to Nairobi in order to stop her from testifying in the earlier case (Sexual Offence No. 62 of 2018), that the said case was consequently withdrawn under section 87(a) of the Criminal Procedure Code, and that the evidence against the accused is overwhelming. The trial magistrate convicted the Appellant on count two on the same statutory basis.
23. On sentence, the trial Court correctly directed itself that the penalty under section 8(3) of the Sexual Offences Act is mandatory and that it retained no sentencing discretion in respect of count one, notwithstanding the mitigation advanced on the Appellant's behalf (that he was a first offender, aged 34, the sole breadwinner for a young family, and responsible for an elderly and ailing mother). It imposed the statutory minimum of twenty years' imprisonment on count one and one year's imprisonment on count two, directing that the sentences run concurrently.
24. I note that the trial Court's judgment does not anywhere address the absence of a recorded voir dire examination, the delay in reporting, or the sexually transmitted infection evidence referred to by the complainant in cross-examination. This is unsurprising, as none of these matters appears to have been raised as a distinct issue before the trial Court; they arise for the first time as grounds of appeal, and I address them as such below, after first testing the trial Court's core findings on the three ingredients against the record.
E. Issues for Determination
25. Having considered the grounds of appeal and the rival submissions, I am satisfied that the appeal turns on the following issues:
Whether the Ingredients of Defilement Were Proved
26. The offence of defilement under section 8(1) of the Sexual Offences Act requires proof of three ingredients: (i) the age of the complainant, (ii) penetration, and (iii) the identity of the perpetrator. This was well highlighted in the case of George Opondo Olunga v Republic [2016] eKLR).
(i) Age
27. PW1 testified that she was born on 18th August 2005. PW2, her mother corroborated this, and a certified copy of the birth certificate was produced as P Exh-1. On the date of the alleged offence, 23rd February 2018, the complainant was in fact twelve (12) years and slightly over six (6) months old, not thirteen years as recited in the charge sheet, the P3 form and the trial Court's judgment. I note this discrepancy for accuracy, but it is immaterial to the outcome: whether the complainant was twelve or thirteen years old, she falls squarely within the twelve-to-fifteen-year bracket contemplated by section 8(3) of the Act, which attracts the identical mandatory minimum sentence of twenty years. Age was, in any event, credibly established by the concurrent evidence of the birth certificate and the complainant's mother, which is precisely the mode of proof endorsed in Francis Omuroni v Uganda, Court of Appeal Criminal Appeal No. 2 of 2000, and adopted in this jurisdiction in Edwin Nyambogo Onsongo v Republic [2016] eKLR; Richard Wahome Chege v Republic [2014] eKLR), namely that age may be proved by birth certificate, parental testimony, medical evidence, or a combination thereof, and need not rest on medical evidence alone. I find that the first ingredient was proved.
(ii) Identification
28. PW1's evidence, corroborated by PW2, was that she knew the Appellant well before the incident as a neighbour and a barber operating at Lukhome trading centre. She named him and identified him in the dock. This is a case of recognition rather than fleeting identification, and recognition of a person well known to a witness is inherently more reliable than identification of a stranger. The long-settled distinction applied in Kenyan authority since Anjononi v Republic [1980] KLR 59, applied consistently in defilement cases. This ingredient was proved.
(iii) Penetration
29. PW1 gave a clear, sequential account of being pulled into the Appellant's house, undressed, and penetrated, and of the pain she thereafter experienced. It is correct, as the Appellant submits, that PW5, the clinical officer who examined her and completed the P3 form, did not record a finding on the state of the hymen and did not himself speak to penetration.
30. This omission is not fatal. It is now firmly settled in this jurisdiction that medical evidence, while desirable, is not a mandatory requirement for a conviction of defilement, and that the direct and cogent testimony of the complainant, properly tested, may suffice, particularly where corroborated by evidence of physical complaint such as pain as was decided in the case of Kaingu Elias Kasomo v Republic, Mombasa Criminal Appeal No. 504 of 2010, cited in Martin Nyongesa Wanyonyi v Republic [2015] eKLR: that medical evidence is not the only evidence by which commission of a sexual offence may be proved; and George Hezron Mwakio v Republic [2010] eKLR). Moreover, under section 2 of the Sexual Offences Act, the "slightest" penetration suffices to constitute the offence, and rupture of the hymen is not a necessary finding. I place reliance on the case of Twehangane Alfred v Uganda, Criminal Appeal No. 139 of 2001, cited by the Court of Appeal in Kenyan defilement jurisprudence. I am satisfied that the trial Court did not err in relying on the complainant's own account, read together with her contemporaneous complaint of genital pain, to find penetration proved.
E. The Voir Dire Ground
31. Counsel for the Appellant submits, correctly on the face of the record, that no voir dire examination is recorded before PW1 gave sworn evidence on 13th January 2020. The authorities relied upon, including MAM v Republic and the Kisumu Court of Appeal decision cited, correctly state the general principle that a child of tender years must be shown, through a recorded voir dire, to understand the nature of an oath before her sworn evidence can safely found a conviction.
32. The difficulty for the Appellant is that the threshold for what constitutes a "child of tender years" for this specific purpose has been authoritatively settled in this jurisdiction at under fourteen years, following Kibangeny Arap Kolil v Republic [1959] EA 92, and reaffirmed in numerous subsequent decisions (see Samson Oginga Ayieyo v Republic, Kisumu Criminal Appeal No. 165 of 2006; DNN v Republic [2021] eKLR, where the High Court confirmed that "the time-honoured 14 years remains the correct threshold for voir dire examination"). Where a witness has already attained fourteen years, our Courts have held a voir dire to be unnecessary (see MK v Republic [2015] eKLR, where the Court of Appeal termed voir dire "unnecessary" for a witness aged fifteen).
33. On the record before me, PW1 was born on 18th August 2005 and testified on 13th January 2020, by which date she was fourteen years and almost five months old — a fact confirmed by the prosecutor's own statement on record that "the complainant is 14 years old and will give sworn evidence." She had, therefore, already passed the threshold at which a voir dire examination is treated as obligatory. While it remains good and prudent practice for a trial Court to satisfy itself, even informally, that any young witness understands the nature of an oath, the absence of a recorded voir dire in respect of a witness who was no longer within the "tender years" bracket does not, without more, render her sworn evidence inadmissible or unsafe. I note further that experienced defence counsel was present throughout PW1's testimony and raised no objection at the time to the taking of her evidence on oath, which is a further indicator that no prejudice arose. This ground fails.
F. The Delay in Reporting
34. This is a matter to which I have given close and particular attention, as it bears directly on the credibility of the complainant.
35. Two distinct periods of delay appear on the record, and it is important to keep them separate, as they raise different considerations.
(i) The complainant's own delay in disclosing the assault
36. The offence is alleged to have occurred on 23rd February 2018. PW1's own evidence, corroborated by PW2 and PW3, is that she did not tell anyone until she confided in her mother on 2nd April 2018 — an interval of approximately five and a half to six weeks. The matter was then reported to the police and the complainant medically examined on 4th and 5th April 2018.
37. I do not find this interval, in the circumstances of this case, to cast reasonable doubt on the complainant's account. PW1 explained that the Appellant warned her not to disclose the incident, that she was in continuing pain, and that she ultimately spoke out only when the pain became unbearable. This is an entirely credible account of a child's reaction to sexual violation by a person known to and in a position of informal authority over her (an adult neighbour who ran the barber shop she frequented).
38. Courts have consistently recognised that children who are victims of sexual abuse commonly delay disclosure out of fear, shame, confusion, or a threat by the perpetrator, and that such delay, without more, does not undermine the child's credibility. In Muganga Chilejo Saha v Republic [2017] eKLR the Court of Appeal observed that child victims of sexual abuse are often devastated by the experience and, given their innocence, may feel too ashamed or afraid to speak of it, including before a Court. This reasoning was applied by the High Court in Okoko v Republic [2022] eKLR to hold that a delay explained by the child's fear of disclosure was not "inordinate" and did not defeat the prosecution's case. I respectfully adopt the same approach here. A delay of some five to six weeks, explained by fear following an explicit threat and by the child's own attempt to bear the resulting pain in silence, is neither inordinate nor unusual, and does not by itself generate reasonable doubt as to whether the offence occurred.
39. I have also considered the countervailing line of authority relied upon in cases such as Waita Munyoki v Republic [2018] eKLR, where a delay in naming the assailant, combined with an absence of any evidence directly linking the accused to the offence and evidence of an existing grudge, was found to raise reasonable doubt. That case is distinguishable: here, there is no suggestion of a grudge, the complainant named the Appellant consistently and immediately upon disclosure, and her identification of him is not in issue. The delay here goes only to the timing of disclosure of an offence whose perpetrator was never in doubt, which is a materially different scenario from delayed or inconsistent identification.
(ii) The delay in arrest following the police report
40. A second, distinct period of delay appears in the evidence of PW4, who candidly admitted in cross-examination that although the offence was reported to police on 5th April 2018, the Appellant was not arrested until 13th July 2018 — an unexplained interval of just over three months, which PW4 could not account for when she stated "I cannot tell why it took time"). This is properly characterised as an investigative delay rather than a delay attributable to the complainant, and it does not reflect on her credibility at all. It is, at most, a legitimate criticism of the diligence of the police investigation. However, an unexplained delay in effecting an arrest, without evidence that it caused any specific prejudice to the Appellant's ability to mount his defence and no such prejudice has been demonstrated or even asserted, does not, on its own, vitiate an otherwise properly proved charge. I find nothing on this score that assists the Appellant.
41. I am accordingly satisfied that neither limb of delay identified in the record, whether considered individually or cumulatively, creates reasonable doubt as to the Appellant's guilt.
G. The Sexually Transmitted Infection Evidence
42. Counsel for the Appellant places considerable weight on the suggestion that the complainant was found, some months after the alleged incident, to have contracted a sexually transmitted infection, said to be syphilis, and argues that the failure to test the Appellant for the same infection is a fatal gap in the prosecution's case, drawing an analogy with cases such as Kevin Moriasi Ondieki v Republic [2020] eKLR, where a documented finding that the complainant had contracted syphilis, combined with medical evidence that the accused tested negative for the same infection, contributed to the quashing of a conviction.
43. Having examined the actual medical exhibits on this record with care, I do not find that analogy to hold. The only evidence of an infection at all is PW1's own answer in cross-examination that she "was not found with HIV but was with an STD," of which she was "not told which one." This assertion is not corroborated, and indeed is contradicted, by the documentary medical evidence before the Court. The treatment card produced as MFI 10/P Exh-11, arising from her examination on 27th November 2019, records a non-reactive PITC (HIV) result and, critically, a negative VDRL — VDRL being the standard serological screening test for syphilis. The P3 form (P Exh-7) completed following her earlier examination in April 2018 likewise does not record a positive finding for any venereal infection; if anything, the examining officer's notes record the absence of abnormal discharge. There is, in short, no positive laboratory finding of syphilis, or of any sexually transmitted infection, anywhere in the documentary record. The suggestion that the complainant tested positive for syphilis does not find support in the exhibits and appears to rest on a misreading of, or an overstatement of the record.
44. This distinguishes the present case sharply from Kevin Moriasi Ondieki, where the quashing of the conviction rested in material part on a documented positive finding in the complainant set against a documented negative finding in the accused, a combination which, taken with other doubts in that recor
