The State v Godfrey Siwela and Johanne Mangena

On 9-10 October 2016 at Sidulini Business Centre, Filabusi, Matabeleland South Province, a dispute arose between the 1st accused (Godfrey Siwela) and the deceased (Mpilo Ndhlovu) over a debt of $18.00 owed to the 1st accused. The 1st accused became aggressive and threw stones and bricks at the deceased. The deceased fled and was pursued by both accused persons into nearby bush for approximately 100 metres. The 2nd accused (Johanne Mangena) armed himself with an iron bar during the chase. After approximately 30 minutes, the 2nd accused returned to the business centre to fetch water. When other patrons followed up, they found the deceased lying dead with serious injuries. Both accused persons had fled the scene. The 1st accused was arrested the following day; the 2nd accused was only arrested seven months later after an ambush. Post-mortem revealed cause of death as bronchoaspiration, extensive right subarachnoid haemorrhage, and head trauma due to assault with blunt object. The deceased had multiple injuries including abrasions and burst lacerations on his head and body.

• Whether the accused persons were guilty of murder
• Whether the defence of self-defence was available to the 1st accused
• Whether the accused persons acted in common purpose as contemplated by section 196 of the Criminal Code
• Whether the murder was committed with actual or constructive intent
• The appropriate verdict based on circumstantial evidence

Both accused were found guilty of murder with constructive intent. Accused 1 (Godfrey Siwela) was sentenced to 18 years imprisonment. Accused 2 (Johanne Mangena) was sentenced to 20 years imprisonment.

Where two or more persons act in common purpose to pursue and assault a victim with dangerous weapons (stones and iron bar), and death results from that assault, they are jointly liable for murder under section 196 of the Criminal Code. Murder with constructive intent is established where the accused reasonably foresaw that their combined assault with weapons could possibly result in death, even if death was not substantially certain. The test for constructive intent requires foreseeability of death as possible, not substantially certain. Where the defence of self-defence is raised, it must be supported by credible evidence and cannot stand on mere allegations contradicted by reliable witnesses. In cases relying on circumstantial evidence, the court may draw inferences consistent with guilt where the circumstances exclude other reasonable possibilities.

The court observed that even liars sometimes tell the truth because human nature makes it impossible to sustain lies throughout. The court noted that if the 1st accused had the audacity to assault the deceased aggressively in public view, it was consistent that he would have done worse in the privacy of the bush. The court commented that while alcohol consumption is not a justification for criminal conduct, it may affect an accused's judgment and can operate in mitigation. The court expressed particular concern about the 2nd accused's attempts to evade justice for seven months, stating that this attitude would be reflected in a higher sentence. The court noted that both accused were mature individuals who should not have resorted to violence and that the deceased exhibited no provocation.

This case illustrates the application of the doctrine of common purpose in murder cases under section 196 of the Criminal Code of Zimbabwe. It demonstrates how courts assess circumstantial evidence in murder cases where there are no eye-witnesses to the actual killing, applying the principles from S v Blom. The judgment clarifies the distinction between murder with actual intent and murder with constructive intent, applying the test of reasonable foreseeability of death as articulated in Robert Mugwanda v The State. The case also demonstrates that self-defence requires evidential support and cannot be sustained merely through allegations contradicted by credible witnesses. The different sentences imposed (18 vs 20 years) show how courts differentiate culpability even where common purpose is established, taking into account factors such as remorse, cooperation, and post-offence conduct.
