#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the offence of murder was proved beyond a reasonable doubt to sustain the conviction, the prosecution case resting wholly on circumstantial evidence
- 2.Whether the appellant's sentence of 30 years' imprisonment should be interfered with
Key legal issues
#Whether the conviction for murder could stand on wholly circumstantial evidence where no witness saw the appellant kill the deceased
Yes. The cumulative circumstances - the appellant hiring and last being seen with the deceased, travelling with him to Migori, the deceased's vehicle being found parked at the appellant's residence, and the appellant's failure to give any plausible explanation - formed a complete chain satisfying the circumstantial evidence tests.
The court applied the settled tests: the circumstances must be cogently established, of definite tendency unerringly pointing to guilt, and cumulatively form a chain so complete that there is no escape from the conclusion that the accused committed the crime. The appellant admitted hiring the deceased and travelling with him to Migori; the deceased's pick-up was found parked at the homestead where the appellant was staying; and the appellant gave no plausible explanation for possession of the vehicle. His denial did not displace the inference of guilt.
Applicability of the doctrine of last seen with the deceased
The doctrine applies: as the last person seen with the deceased, the appellant was duty-bound to explain the death, and his failure to do so justified the inference that he killed the deceased.
Relying on Nigerian authorities adopted in Daniel Munyui Chiragu, the court held that the onus of proof remains on the prosecution, but where circumstantial evidence is overwhelming against the person last seen with the deceased, that person must offer a satisfactory explanation for the death. The appellant's claim that he could not remember the events and that the deceased returned safely to Nairobi was rejected as not plausible.
Whether the 30-year sentence should be disturbed
No. Following Muruatetu, the mandatory death sentence is unconstitutional and discretion is restored, but the trial judge properly exercised that discretion in imposing 30 years given the deliberate planning and malice aforethought.
The court noted that although Section 204 of the Penal Code prescribes the death penalty for murder, Muruatetu declared its mandatory nature unconstitutional, enabling individualised sentencing. The crime was committed with deliberate planning, malice and intent to kill by strangulation. The resentencing to 30 years was a proper exercise of discretion, and the appeal against sentence lacked merit.
Legal principles established
#- A first appellate court must re-examine and analyse the evidence afresh and reach its own conclusions, while allowing for the trial court's advantage of seeing and hearing the witnesses.
- Circumstantial evidence can found a conviction only if the inculpatory facts are incompatible with innocence, are incapable of explanation on any other reasonable hypothesis, and form a complete and unbroken chain pointing unerringly to the accused's guilt.
- Under the doctrine of last seen, where an accused was last seen with the deceased, the accused bears a duty to explain how the deceased met death; absent a satisfactory explanation, the court is justified in drawing the inference that the accused killed the deceased.
Court orders
#- 1.Appeal dismissed in its entirety

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.
We hold that the appeal is without merit and is dismissed in its entirety.
The trial judge correctly exercised his discretion in imposing a 30-year prison term, and there is no ground to interfere with the sentence.
to convict on the basis of circumstantial evidence, the chain of events must be so complete that it establishes the culpability of the appellant, and no one else without any reasonable doubt.
In the absence of any explanation, the court is justified in drawing the inference that the accused killed the deceased.
Suspicion however strong, cannot provide a basis for inferring guilt.
Issues in the judgment
#The judgment does not state the appeal number of the present appeal or the High Court case number, and no neutral citation appears.
Internal inconsistency in numbering of quoted paragraphs from Republic vs. Mohammed: two passages are both labelled (59).
