Katana Chengo Karisa v Republic
The bottom line
#Kenya's Court of Appeal upheld a murder conviction and 30-year sentence based on circumstantial evidence, confirming that a complete chain of facts can sustain a conviction.
What this practically means

#Key legal issues
#Duty of a first appellate court
The Court was obliged to subject the whole evidence to a fresh and exhaustive examination and draw its own conclusions, making allowance for the trial court's advantage of seeing and hearing the witnesses.
Relying on Okeno v Republic, the Court restated that a first appellate court does not merely scrutinise the evidence for some support of the trial court's findings; it must itself weigh conflicting evidence, draw its own conclusions, and only then decide whether the trial court's findings should stand. This framework governed the entire re-evaluation of the prosecution's circumstantial case.
Sufficiency of circumstantial evidence
The circumstantial evidence - the appellant brandishing a blood-stained panga, declaring he had killed the deceased, leading witnesses to the body, and stating the motive of bewitchment - formed a complete chain pointing inescapably to the appellant's guilt.
Applying Koske, Musoke and Abanga, the Court tested each link in the chain separately and found the inculpatory facts incompatible with innocence. The absence of scene photographs and the failure to subject the panga to Government Chemist analysis were weighed as possible co-existing circumstances but found insufficient to weaken the inference, given multiple consistent and corroborative witnesses.
Malice aforethought
Malice aforethought was established through the appellant's expressed motive and the nature of the injuries inflicted.
Section 206 of the Penal Code deems malice aforethought established by an intention to cause death or grievous harm. The appellant repeatedly told witnesses he had killed the deceased for bewitching him, and the post mortem showed deep cuts to the head, neck, larynx and pharynx, demonstrating intent to cause grievous harm. The Court applied the factors in Chesakit v Uganda: body part injured, weapon used, type of injuries and conduct of the accused.
Alibi defence
The alibi that the appellant went to the scene only after being called by his sister was unconvincing because he never named or called the sister, and prosecution evidence placed him at the scene before midnight.
Restating Wang'ombe v Republic, the Court confirmed the alibi imposes no burden of proof on the accused and the prosecution should test an alibi where possible. However, weighing the unsworn statement against several consistent witness testimonies placing the appellant at the scene declaring the killing before midnight, the alibi was displaced. The conviction followed.
Legal principles established
#- On a first appeal, the appellate court must re-examine the whole evidence afresh and make its own findings, while making allowance for the trial court's advantage of seeing and hearing the witnesses.
- A conviction on circumstantial evidence is justified only where the inculpatory facts are incompatible with the innocence of the accused and incapable of explanation on any other reasonable hypothesis than guilt, and the burden of proving this remains on the prosecution.
- Before drawing an inference of guilt from circumstantial evidence, the court must be satisfied there are no co-existing circumstances which would weaken or destroy that inference; the circumstances taken cumulatively should form a complete chain.
- An accused who raises an alibi assumes no burden of proof; the burden of proving guilt remains on the prosecution, and it is sufficient for the trial court to weigh the alibi against the prosecution evidence.
