The first appellant (Matanga), together with the second appellant (Kanyemba, who died before the appeal was heard) and Charles Farai Mubika, plotted to kill the first appellant's employer, Heather, and steal her property. The first appellant carried out the killing by strangling her and hitting her head against a rock, then burning her body to ashes. He stole her wallet, cell phone, and keys. The second appellant subsequently removed the deceased's motor vehicle with the first appellant's assistance, and together with Mubika drove it around Harare and sold speakers from it. The first appellant was 20 years old at the time and attempted suicide by taking rat poison when police arrived. He made a warned and cautioned statement in hospital which was confirmed by a magistrate two days later. He pleaded not guilty to murder (offering culpable homicide) and guilty to theft of wallet and cell phone but not guilty to theft of the motor vehicle.
Appeal against conviction and sentence for both murder and theft dismissed. Death sentence for murder with actual intent and eight years imprisonment with labour for theft of motor vehicle confirmed.
1. Self-defense requires: (i) an unlawful attack; (ii) upon the accused or third party; (iii) that has commenced or is imminent; (iv) action necessary to avert the attack; and (v) reasonable means used to avert the attack. A verbal attack alone does not justify physical violence in self-defense. 2. For provocation to reduce murder to culpable homicide, the provocation must be sufficient to justify the loss of self-control and the retaliation must be proportionate to the provocation received. 3. An accused challenging the admissibility of a confirmed warned and cautioned statement bears the burden of proving it was not made freely and voluntarily. 4. Where an accused gives multiple contradictory versions of events, credibility may be rejected and the version most consistent with other evidence accepted. 5. Mitigating factors such as youth and first offender status may be eclipsed by aggravating circumstances including premeditation, brutality, and callousness in determining whether extenuating circumstances exist to avoid capital punishment.
The court noted that theft from employers generally and theft of motor vehicles in particular were both prevalent and serious crimes in Zimbabwe, warranting substantial sentences. The court observed that the speed with which the appellant took and shared the deceased's property after burning her body suggested premeditation, though this was put beyond doubt by the warned and cautioned statement itself.
This Zimbabwean Supreme Court case illustrates the strict application of requirements for the defenses of self-defense and provocation in murder cases. It demonstrates that self-defense requires a physical attack, not merely verbal abuse, and that the response must be necessary and reasonable. For provocation to reduce murder to culpable homicide, the provocation must be proportionate to the reaction. The case also reinforces principles regarding the admissibility of confession statements and the burden on an accused to prove involuntariness. It shows that mitigating factors like youth and being a first offender can be eclipsed by aggravating circumstances such as premeditation, brutality, and callousness. The judgment emphasizes that theft from employers and motor vehicle theft are serious prevalent crimes warranting substantial sentences.
