Ntukai & another v Republic (Criminal Appeal 179 of 2017) [2025] KECA 2140 (KLR)
The bottom line
#Kenya's Court of Appeal freed one man convicted of murder on mere suspicion but upheld the death sentence of the other, whose guilt was proved through circumstantial evidence.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the appellants were minors at the time of the trial
- 2.Whether the elements of murder were proved and, if so, whether the circumstances irresistibly pointed to the appellants as the ones who had murdered the deceased
- 3.Whether the death sentence meted out was appropriate in the circumstances of the case
Key legal issues
#Age of the accused and trial as a minor
The age issue raised for the first time on appeal was dismissed; the appellants were adults at trial, as shown by unchallenged mental assessment reports recording ages of 18 and 19, and the trial submissions never alleged minority.
In a criminal trial age impacts criminal responsibility and sentencing. Where it appears to a court that an accused is under 18, it must inquire into age and take evidence including medical evidence. Here the trial judgment did not deal with age, the written submissions raised nothing on age, the defence never claimed minority on oath, and the mental assessment reports showing ages 18 and 19 were never challenged. The issue was a red herring.
Sufficiency of circumstantial evidence against the 1st appellant
The conviction of the 1st appellant was sound; the cumulative circumstances - being last seen with the deceased, falsely denying the relationship and his presence, and relocating immediately after the murder - formed a complete chain excluding any other rational inference.
No witness saw the killing, so the case rested solely on circumstantial evidence. Applying the Abanga tests, the court found cogent evidence that the appellants were with the deceased that evening, that the 1st appellant was her boyfriend, that he was the last person seen with her alive, that he falsely denied both facts, and that he moved away from his residence immediately after the murder. He offered no explanation, so the only rational conclusion was his guilt.
Sufficiency of evidence against the 2nd appellant
The evidence against the 2nd appellant was insufficient; suspicion, however strong, cannot sustain a conviction, and his conviction and sentence were quashed.
The 2nd appellant was seen in the company of the 1st appellant and the deceased, but his own uncontroverted evidence was that he left them and went his way when asked. The only other links - friendship with the 1st appellant and presence nearby - amounted to mere suspicion. The burden of excluding every reasonable hypothesis consistent with innocence rests solely on the prosecution and never shifts to the accused, and that burden was not discharged against him.
Accomplice evidence and corroboration
The 2nd appellant was an accomplice whose evidence required corroboration; here the corroboration was found in the independent testimony of PW 2, PW 6, PW 7 and PW 9, to which his account was a mere confirmation.
A court dealing with accomplice witnesses must first assess credibility, then decide whether to convict on uncorroborated accomplice evidence or seek corroboration, warning itself accordingly. The 2nd appellant's account that he left the 1st appellant with the deceased merely confirmed the prosecution evidence of the joint sighting; the independent witnesses supplied the corroboration. No torture-based exclusion under Article 50(4) was found by the court on these facts.
Appropriateness of the death sentence for the 1st appellant
The death sentence was lawful and appropriate; the trial court considered mitigation (first offender, remorse) and the gravity of the brutal murder of a young, defenceless girl, so the appellate court would not interfere.
An appellate court interferes with sentence only on error of law, misapplication of sentencing principles, or manifest excess or inadequacy. Although the judgment predated Muruatetu II, the learned Judge received and considered mitigation and the sentencing guidelines. Given the vicious, targeted wounds and the defenceless victim, no improper exercise of discretion was shown and the sentence stood.
Legal principles established
#- A conviction resting entirely on circumstantial evidence must satisfy the three Abanga tests: circumstances cogently and firmly established, of definite tendency unerringly pointing to guilt, and forming a complete chain excluding any other conclusion
- An accused who raises an alibi bears no duty to prove it; the prosecution must still prove guilt including presence at the scene
- Suspicion alone, however strong, cannot be the basis of a conviction
- The doctrine of last seen alive is a circumstantial-evidence doctrine under which the person last seen with the deceased is expected to explain what happened
- Evidence of an accomplice must be considered with care and requires corroboration before it can found a conviction
- An appellate court may interfere with sentence only where the trial court considered an irrelevant factor, failed to consider a relevant factor, or the sentence is manifestly harsh or low; otherwise sentencing discretion is left to the trial court
Court orders
#- 1.The 2nd appellant's conviction is quashed and his sentence set aside
- 2.The 2nd appellant is ordered to be set free unless otherwise lawfully held
- 3.The 1st appellant's appeal against conviction and sentence is dismissed
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court at Nanyuki
- Jurisdiction invoked
- First appellate jurisdiction over an appeal from the High Court exercising original criminal jurisdiction in a murder trial (Constitution and Court of Appeal jurisdiction on appeals as of right on conviction and sentence)
Relief refused
#1st appellant's challenge to conviction on circumstantial evidence
The circumstantial evidence against the 1st appellant was overwhelming and irresistibly pointed to his guilt
1st appellant's challenge to the death sentence
The trial court properly exercised its sentencing discretion considering mitigation; the sentence was deserved
Claim that the appellants were minors who should have been tried as minors
Raised for the first time on appeal; mental assessment reports showed ages of 18 and 19 and ages were never challenged at trial
Costs
No order as to costs appears in the judgment; the judgment ends with the disposition on conviction and sentence.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
It is settled law that when a case rests entirely on circumstantial evidence, such evidence must satisfy three tests
the circumstance taken cumulatively should form a chain so complete that there is no escape from the conclusion that within all human possibility the crime was committed by the accused and no one else.
The burden of proving the inculpatory facts, and showing that no other reasonable hypothesis can be drawn from them, rests solely on the prosecution
The prosecution must still prove the accused's guilt including his presence at the scene, even if the alibi was weak and unconvincing
There may have been suspicion to link him, but suspicion alone, however strong, could not be the basis of his conviction.
As indicated in the foregoing, the 2nd appellant's appeal is wholly allowed and he is hereby ordered to be set free unless he is otherwise being lawfully held.
In conclusion, therefore, we find no merit in the appeal by the 1st appellant as regards conviction and sentence. This appeal is dismissed.
Issues in the judgment
#The judgment twice states the murder occurred on 16th May 2012 but the opening paragraph records the date as 16th May 2012 only after first stating the conviction particulars with a different year format; more materially, paragraph 3 records the appeal-citation date context while the memorandum of appeal is dated 2017 yet a supplementary memorandum is dated 28th February 2025, and the delivery date is 2025 - an unusually long pendency not explained in the judgment.
The name of the cited authority 'Kamau v Republic' appears with two different years/citations in the same judgment ([2021] KECA 314 (KLR) when cited by counsel, and [2024] KECA 314 (KLR) when quoted by the court), an internal inconsistency.
