Paul Mwenda Muriungi v Republic
The bottom line
#Kenya's Court of Appeal upheld a murder conviction based on last-seen evidence but replaced the mandatory death sentence with 40 years' imprisonment.
What this practically means
#Executive summary
#Key legal issues
#Proof of guilt by circumstantial evidence under the doctrine of last seen with the deceased
The appellant was the last person seen with the deceased alive; three witnesses saw him assaulting her on the material night and he offered no explanation, so guilt was inferred beyond reasonable doubt
PW1 and PW3 last saw the deceased leave with the appellant; PW4 saw them walking together; PW2 and PW5, who knew the appellant, saw him assaulting the deceased at about 1:00 a.m. The appellant's bare denial of fabrication was unexplained. Circumstantial evidence must reach moral certainty excluding any co-existing circumstance weakening the inference; none existed here, so the prosecution proved causation beyond reasonable doubt.
Malice aforethought in murder
Malice aforethought was established by strangulation and head injury, calculated conduct in luring the deceased from her parents' home, history of domestic violence, and threats against intervenors, satisfying section 206 of the Penal Code
Section 206 deems malice aforethought established by intention to cause death or grievous harm. The post-mortem showed death by asphyxiation from strangulation with head injury contributing. The appellant lured the deceased from her parental home, beat her relentlessly, and threatened those who intervened; the conduct was unprovoked and calculated, establishing both actus reus and mens rea.
Constitutionality of the mandatory death sentence post-Muruatetu
The death sentence, which was mandatory at the time of trial, was set aside and substituted with forty years' imprisonment
The trial court was constrained by the then-mandatory death penalty. Following the Supreme Court's Muruatetu decision, the Court held itself at liberty to impose any other lawful sentence and, exercising that discretion, substituted forty years' imprisonment running from the date of the High Court sentence.
Effect of minor contradictions in prosecution evidence
Minor contradictions relied on by the appellant did not vitiate the conviction; only substantial and fundamental contradictions creating doubt are fatal
The appellant alleged contradictions among PW2, PW4 and PW5 regarding clothing, weapon and injuries. Applying Richard Munene v Republic, the Court treated such inconsistencies as not going to the root of the case, since PW2 and PW5's eyewitness accounts of the assault at night, by witnesses who knew the appellant, remained intact and unshaken.
Legal principles established
#- The last-seen doctrine obliges the person last seen with the deceased to give a minimum explanation of the events leading to the death, but courts should still look for some corroboration even where the time gap is small
- On a first appeal the appellate court must re-evaluate the evidence afresh and draw its own conclusions, while making allowance for the trial court's advantage of seeing and hearing the witnesses
- Following Muruatetu, courts are at liberty to impose any lawful sentence other than the mandatory death sentence for murder
