The State v Tavengwa Mupuna

The accused and the deceased were husband and wife, married for approximately 20 years. On 28 December 2014 at Muzemba Village, Mt Darwin, the accused killed his wife Constance Muzemba by striking her twice on the head with an axe. The accused suspected his wife was having an extramarital affair with Francis Muparira. On 25 December 2014, the accused fought with Francis Muparira and lost the fight. The accused reported the assault to police on 26 December 2014. On the night of 28 December 2014 at about 0200 hours, while in bed with the deceased, the accused armed himself with an axe and struck the deceased twice on the head, killing her instantly. The axe blade remained embedded in her skull. The accused fled and was arrested on 12 January 2015 at the Mozambican border. Post-mortem examination revealed the deceased died from severe bleeding and brain injuries caused by the axe blows.

• Whether the accused murdered the deceased with actual intent
• Whether the defence of provocation reduced murder to culpable homicide under section 239 of the Criminal Law (Codification and Reform) Act
• Whether the defence of self-defence under section 253 was available to the accused
• The credibility of the accused's version that he found Francis Muparira in his bedroom with his wife on the night in question

The accused was found guilty of murder as defined in section 47(1)(a) of the Criminal Law (Codification and Reform) Act (murder with actual intent) and sentenced to 15 years imprisonment.

Where an accused raises defences of provocation and self-defence to a murder charge, but the defences are underpinned by falsehoods and contradicted by the physical evidence, prior statements, and inherent improbabilities, the court will reject those defences entirely. Murder with actual intent under section 47(1)(a) will be established where the accused deliberately armed himself with a lethal weapon and struck fatal blows to the victim's head, regardless of claims of provocation or self-defence that lack credibility. A subjective belief in a spouse's infidelity may constitute some element of provocation for sentencing purposes, but will not reduce murder to culpable homicide where the killing was premeditated and executed in cold blood without genuine provocation at the moment of the killing.

The court observed that cases of domestic violence leading to loss of life are very prevalent, with many spouses (especially females) losing their lives at the hands of their loved ones. The court emphasized that courts have a duty to uphold the sanctity of human life and that no person has the right to shed the blood of another, whatever the circumstances. The court noted that even if suspicions of unfaithfulness were well-founded, this does not justify resorting to violence. The court commented that deterrent sentences are called for in such cases to address the prevalence of domestic violence.

This case illustrates the Zimbabwean courts' approach to domestic violence murders and the scrutiny applied to defences of provocation and self-defence. It demonstrates that courts will reject fabricated defences when contradicted by physical evidence and prior statements. The case emphasizes the sanctity of human life and the need for deterrent sentences in domestic violence cases involving murder, while still considering mitigating factors such as suspected infidelity. It reinforces that suspicion of a spouse's unfaithfulness, even if subjectively believed, does not justify resort to violence and will not constitute sufficient provocation to reduce murder to culpable homicide when the killing is premeditated and executed in cold blood.
