The State v Isaac Masare Bosha and Kudakwashe Tazvivinga and Thomas Suma

On 18 October 2007 at around 1230 hours at Munyathi River, Zhombe, the deceased Tinos Karuka was assaulted and killed. The three accused persons were gold panners. The State alleged that a group of people, including the accused, searched for the deceased who had allegedly assaulted accused two's brother (Taurai Tazvivinga). The group, armed with axes, knives, sticks and other weapons, located the deceased along Munyathi River. When the deceased fled, they gave chase. According to the State's key witness Sikirwai Mpofu, accused three struck the deceased on the head with a stone causing him to fall, accused one struck him on the right ankle with an axe, and accused two struck him on the right leg with the axe. The deceased died from his injuries. The post-mortem report indicated cause of death as brain haemorrhage, skull fractures, and assault trauma. Fourteen persons were initially arrested in 2007, but only these three accused were indicted for trial in 2014. All three accused denied participating in the assault, claiming either they were not present or were part of the group intending only to apprehend the deceased but did not assault him.

• Whether the State proved beyond reasonable doubt that the accused persons caused the death of the deceased
• Whether the evidence of the single eye witness (Sikirwai Mpofu) was credible and satisfactory in all material respects to sustain a conviction under section 269 of the Criminal Procedure and Evidence Act
• Whether the State discharged the onus of proving all essential elements of the charge of murder beyond reasonable doubt

The accused persons were found not guilty and acquitted of the crime of murder.

Single witness evidence, while legally sufficient for conviction under section 269 of the Criminal Procedure and Evidence Act, must be credible and satisfactory in every material respect before a court can convict. The test is whether the evidence is found to be satisfactory in every material respect (S v Nathoo Supermarket 1987 (2) ZLR 136 (SC)). The State bears the onus of proving all essential elements of a criminal charge beyond reasonable doubt. An accused cannot be convicted merely because the court disbelieves their explanation - if there is any reasonable possibility of the explanation being true, the accused is entitled to acquittal (R v Difford 1937 D 370). Where the danger of false incrimination has not been eliminated and reasonable doubt exists, the benefit of that doubt must be given to the accused.

The court observed that the manner in which the matter was investigated and handled by the police "leaves a lot to be desired" and noted that prosecution must be premised on sufficient evidence and "must never be seen as a fishing expedition." The court made critical observations about a police officer forging witness signatures on statements, describing this as "a clear forgery." The court also commented that it would have been safer to rely on medical evidence from the pathologist rather than witness observations of injuries, as the pathologist's independent examination under section 278(3) of the Criminal Procedure and Evidence Act was more reliable. The court noted without deciding that Sikirwai Mpofu's degree of participation appeared limited to apprehension of the deceased and thus he should not be treated as an accomplice under section 195 of the Criminal Law (Codification and Reform) Act.

This case demonstrates the rigorous standard required for conviction based on single witness evidence in Zimbabwean criminal law (though the judgment is from Zimbabwe, it applies similar common law principles to South Africa). It emphasizes that even where a single witness account is legally permissible under section 269 of the Criminal Procedure and Evidence Act, such evidence must be credible and satisfactory in every material respect. The case also highlights the importance of proper police investigation procedures and the principle that an accused cannot be convicted merely because their defense is disbelieved - the State must prove guilt beyond reasonable doubt. It illustrates the application of the Difford principle that where there is any reasonable possibility of an accused's explanation being true, they are entitled to acquittal.
