In January 2017, the appellant was convicted of two counts of murder with actual intent in aggravating circumstances and sentenced to death. On 12 January 2017, the appellant shot and killed Mboneli Joko Ncube with an Optima shotgun, then mutilated the body and buried dismembered parts in four shallow graves at a property in Burnside, Bulawayo. On 29 January 2017, the appellant shot and killed Cyprian Kadzurunga, robbed him of his LG cell phone and Asus laptop, transported the body in a wheelbarrow to his vehicle, and buried it at the same Burnside property after hiring individuals to dig a grave under false pretenses. After both murders, the appellant sent SMS messages from the deceased persons' phones to their relatives, pretending the deceased had fled to South Africa. The appellant's defence was that he was intoxicated by alcohol, heroine and crystal meth, and acted under the command of "Lucifer" when committing the offences. Medical practitioners examined him on 16 November 2017 and found him mentally stable and fit to stand trial. The High Court rejected his insanity defence, finding the meticulous planning and execution of the crimes demonstrated he was in full control of his mental faculties.
The appeal against both conviction and sentence was dismissed. The conviction and sentence of death in respect of both counts of murder with actual intent were confirmed.
The binding legal principles are: (1) Where an accused relies on the defence of insanity or mental incapacity, the burden rests on the accused to prove on a balance of probabilities that he or she suffered from mental incapacity at the relevant time, in terms of the proviso to s 18(4) of the Criminal Law (Codification and Reform) Act; (2) A mere assertion of mental incapacity without supporting evidence is insufficient to establish the defence; (3) Temporary mental disorder or disability caused by the voluntary effects of alcohol or drugs does not constitute mental incapacity under the proviso to s 225 of the Code; (4) Courts must assess mental capacity at the time of the offence by examining the totality of the accused's conduct, including planning, execution, and post-offence behavior; (5) Meticulous planning, execution of crimes over several days, taking steps to avoid detection, and attempting to escape custody are evidence of full mental capacity; (6) An appellate court will not interfere with factual findings of a trial court unless those findings are grossly unreasonable or the trial court took leave of its senses; (7) An appellate court will not interfere with a sentence merely because it would have imposed a different sentence, unless there is evidence of serious misdirection in the assessment of sentence.
The Court noted as obiter that when imposing the death sentence for multiple counts of murder, the proper approach is to impose a separate death sentence on each count, rather than one overall death sentence. The Court cited S v Dube 1992(1) ZLR 234(S) for this proposition. This prevents complications if an appeal succeeds on one count but fails on another. However, since the appeal failed entirely in this case, the technical deficiency in sentencing did not warrant resentencing. The Court also observed that the appellant may have killed the deceased for motives including harvesting body parts for nefarious ritual purposes, though this was not definitively established. The Court expressed concern about the appellant's refusal to account for missing body parts, claiming he made a vow to "Lucifer" not to speak about it, which the Court characterized as bordering on arrogance given the medical determination of his sound mental state.
This case reinforces important principles in Zimbabwean criminal law regarding the insanity defence and mental incapacity. It clarifies that the burden of proving mental incapacity at the time of the offence rests on the accused under s 18(4) of the Criminal Law (Codification and Reform) Act. The judgment emphasizes that temporary mental disorder caused by voluntary intoxication from alcohol or drugs does not constitute a valid defence per the proviso to s 225 of the Code. The case demonstrates that courts will examine the totality of an accused's conduct, planning, and post-offence behavior to assess mental capacity, rather than accepting bare assertions of incapacity. It also confirms the application of aggravating circumstances warranting capital punishment under s 47 of the Code, including premeditation, multiple murders in a series, and murder committed during robbery. The judgment provides guidance on appellate review of sentencing discretion and factual findings, reiterating that appellate courts will not interfere unless findings are grossly unreasonable or demonstrate a serious misdirection.
