1. The appellant, Fredrick Nyakanga Nyarangi, was convicted of the offence of defilement contrary to section 8(1) as read with section 8(3) of the Sexual Offences Act and on 11th November 2023 was sentenced to serve twenty (20) years' imprisonment.
2. Aggrieved by both the conviction and the sentence, the appellant lodged the present appeal, contending that the learned trial magistrate erred in convicting him on insufficient and contradictory evidence, relied on inadequate investigations, violated his right to a fair trial, and imposed a sentence that was harsh and excessive. He accordingly prays that the conviction be quashed, the sentence set aside, and that he be set at liberty.
3. Pursuant to the directions of the Court, the appeal was canvassed by way of written submissions. The appellant filed written submissions dated 04th May 2026, in which he maintained that the prosecution failed to prove the charge beyond reasonable doubt. He challenged the conviction on the grounds that the prosecution evidence was inconsistent, the investigations were inadequate, and the learned trial magistrate failed to properly evaluate his defence before convicting him. He also urged this Court to interfere with the sentence on the ground that it was harsh and excessive. Although granted an opportunity to respond, the respondent did not file any written submissions.
4. This being a first appeal, this Court is under a duty to reconsider and re-evaluate the entire evidence adduced before the trial court and draw its own independent conclusions, while bearing in mind that it neither saw nor heard the witnesses testify and must therefore make due allowance for that disadvantage. As stated in Okeno v Republic, a first appellate court must subject the whole of the evidence to a fresh and exhaustive examination and arrive at its own independent conclusions.
5. Having carefully considered the Record of Appeal dated 08th April 2026, the grounds of Appeal, and the Appellant's Written Submissions, the following issues arise for determination:
1) Whether the prosecution proved the case beyond reasonable doubt.
2) Whether the alleged inconsistencies, contradictions and investigative shortcomings rendered the conviction unsafe.
3) Whether the learned trial magistrate properly considered and evaluated the appellant's defence.
4) Whether there is any basis for interfering with the sentence imposed by the trial court
6. In Gikunju v Republic [2025] KECA 401 (KLR) , the Court of Appeal held that, for the prosecution to secure a conviction for the offence of defilement, it must prove three essential ingredients: the age of the complainant, penetration, and the identity of the perpetrator.
7. Age is an essential ingredient of the offence of defilement since it determines both the applicability of section 8 of the Sexual Offences Act and the sentence upon conviction. The evidence on age comprised the Charge Sheet dated 02nd December 2019, which described the complainant as being 12 years old, the complainant's testimony during the voire dire examination on 10th February 2021 that she was 13 years old, and the Age Assessment Report dated 11th December 2019, which assessed her age at between 14 and 15 years. Section 8(3) applies where the complainant is aged twelve years or more but under fifteen years. The evidence consistently placed the complainant within that statutory age bracket.
8. I am therefore satisfied that the prosecution proved the complainant's age beyond reasonable doubt, and I find no error in the learned trial magistrate's conclusion on that ingredient of the offence.
9. The second ingredient requiring proof is penetration. Under section 2 of the Sexual Offences Act, penetration means the partial or complete insertion of the genital organs of one person into the genital organs of another. To establish that ingredient, the complainant testified that the appellant lured her into a maize plantation, removed her clothes, removed his trousers, inserted his penis into her vagina, and warned her not to disclose the incident to anyone.
10. The complainant's testimony that the appellant inserted his penis into her vagina was supported by the P3 Form dated 30th November 2019 and the Post Rape Care (PRC) Form dated 30th December 2019, which showed that her hymen was broken. The examining clinical officer concluded that the findings were consistent with penetration.
11. Having reconsidered and re-evaluated the evidence on record, I am satisfied, as was the learned trial magistrate, that the complainant's testimony, taken together with the medical evidence, proved the element of penetration beyond reasonable doubt.
12. The final ingredient requiring proof was the identity of the perpetrator. The prosecution bore the burden of proving beyond reasonable doubt that it was the appellant, and no other person, who committed the offence.
13. The complainant testified that she had previously seen the appellant, who worked at a neighbour's home. She stated that the appellant lured her into a maize plantation where he defiled her and that, following his arrest, she identified him to the Nyumba Kumi members. PW2 similarly testified that the appellant worked at a neighbour's home and confirmed that the complainant identified him when he was brought before them.
14. Having carefully reviewed the evidence on record, I am satisfied that the prosecution proved beyond reasonable doubt that it was the appellant who committed the offence. The complainant's evidence as to the appellant's involvement remained consistent throughout the trial, and nothing emerged from the cross-examination or the defence to cast doubt on her testimony. I therefore find that the prosecution proved the appellant's identity beyond reasonable doubt.
15. The appellant further contends that the conviction was unsafe because the prosecution evidence contained material inconsistencies and contradictions. He argues that the complainant did not specify the particular Friday on which the offence was committed, that her evidence regarding what transpired after the incident conflicted with that of the other prosecution witnesses, that she had only seen him before the incident but did not know his name, that the investigating officer failed to visit the scene of the crime, and that the learned trial magistrate failed to properly evaluate his defence.
16. The law is settled that not every inconsistency or discrepancy in the prosecution evidence is fatal to a conviction. In Sitati v Republic [2026] KECA 1155 (KLR), the Court of Appeal reaffirmed that only contradictions which go to the root of the prosecution's case and weaken the chain of evidence warrant appellate intervention. Minor inconsistencies which do not affect the material particulars establishing the offence do not render otherwise credible evidence unreliable.
17. I have carefully considered each of the appellant's complaints. Although the complainant did not specify the particular Friday on which the offence occurred, the Charge Sheet expressly alleged that the offence was committed on 29th November 2019, and the appellant neither alleged nor demonstrated that he was misled or prejudiced in the preparation of his defence. Equally, the complaint regarding the complainant's movements after the incident did not detract from her consistent account that the appellant defiled her, while the fact that she had previously seen the appellant without knowing his name did not diminish the reliability of her evidence, as she consistently pointed him out after his arrest.
18. As regards the complaint that the investigating officer did not visit the scene, the appellant has not demonstrated how that omission prejudiced his defence or undermined the cogent evidence adduced by the prosecution. I therefore find that the alleged inconsistencies and investigative shortcomings did not go to the root of the prosecution's case or render the conviction unsafe.
19. The appellant also challenges the sentence of twenty (20) years' imprisonment as being harsh and excessive. In Stanley Warui Gacheru v Republic [2014] KECA 459 (KLR), the Court of Appeal held that:
"Sentence is a matter that rests in the discretion of the trial court... the appellate court will not easily interfere with sentence unless the sentence is manifestly excessive in the circumstances of the case, or the trial court overlooked some material factor, took into account some wrong material, or acted on a wrong principle."
20. The appellant was convicted under section 8(1) as read with section 8(3) of the Sexual Offences Act. Having found that the complainant fell within the age bracket prescribed under section 8(3), the applicable sentence was imprisonment for a term of not less than twenty (20) years. The record further shows that the appellant was afforded an opportunity to mitigate before sentence was pronounced, and there is nothing to suggest that the learned trial magistrate acted on a wrong principle or overlooked any material consideration.
21. I therefore find no basis for interfering with the sentence imposed by the trial court. The sentence was lawful, and the appellant has not demonstrated any error in principle warranting appellate intervention.
22. Consequently, the appeal lacks merit and is hereby dismissed in its entirety. The conviction and sentence imposed by the Senior Principal Magistrate's Court at Keroka in MCSO E045 of 2019 are hereby affirmed.
2. Aggrieved by both the conviction and the sentence, the appellant lodged the present appeal, contending that the learned trial magistrate erred in convicting him on insufficient and contradictory evidence, relied on inadequate investigations, violated his right to a fair trial, and imposed a sentence that was harsh and excessive. He accordingly prays that the conviction be quashed, the sentence set aside, and that he be set at liberty.
