The State v Pretty Mbikiza

The accused, a 33-year-old married woman with four children, was charged with the murder of Owen Munyanyi (36 years old) on 10 May 2021 at Dewure Ministry of Transport compound in Gutu, Masvingo. The accused and deceased, both married to other people, had an illicit love affair that began in October 2020. On 9 May 2021, the deceased left his home to go to his workplace at Dewure compound, spending the night at his brother's homestead. With the knowledge of Ratidzai Munyanyi (the deceased's sister-in-law and accused's close friend), the accused and deceased planned to spend time together at Dewure compound. On 10 May 2021, they travelled together to Dewure compound. According to the accused, after arriving they had sexual intercourse, after which both felt very hot and the deceased developed breathing problems, vomited, and died. The accused reported the death to Ratidzai Munyanyi and her aunt Revenia Ndebele but did not report it to police or other family members to conceal the affair. The deceased's decomposed body was discovered six days later on 15 May 2021. A post-mortem revealed extensive subdermal bleeding on the left side of the neck, left shoulder, chest and upper abdomen, with cause of death stated as haemorrhagic shock from blunt trauma.

• Whether the State proved beyond reasonable doubt that the accused caused the death of the deceased
• Whether the medical evidence established that death was caused by assault rather than other causes
• Whether the accused's conduct after the death was consistent with guilt
• Whether the inference of murder could be drawn from the circumstantial evidence

Not guilty and acquitted

In a murder prosecution based on circumstantial evidence, the State must prove its case beyond reasonable doubt by establishing facts from which an inference of guilt can be drawn that is consistent with all proved facts and excludes every reasonable inference other than guilt. Where medical evidence cannot establish with certainty whether injuries resulted from assault or accidental trauma, where there is no direct evidence of assault, no proven motive, and where the accused's conduct after the death is inconsistent with a guilty mind, the inference of murder cannot be sustained and the accused must be acquitted. The doubt arising from uncertainty as to the proximate cause of death must favour the accused.

The court made observations about the troubling conduct of Ratidzai Munyanyi, who was described as not being a candid witness and whose behavior in concealing her brother-in-law's death for six days and her role in facilitating the illicit affair was characterized as 'shocking'. The court noted her poor demeanor and unwillingness to disclose incriminating evidence about her own involvement. The court also commented on the difficulty of establishing facts where a death is 'mysterious' and noted it was 'a herculean task' akin to 'looking for a needle in the proverbial haystack'. The court observed that the accused was 'far more a convincing witness' than Ratidzai Munyanyi and that the accused 'bared it all in her evidence'.

This case demonstrates the application of the criminal standard of proof beyond reasonable doubt in Zimbabwe, particularly in cases relying on circumstantial evidence. It illustrates that where medical evidence cannot conclusively establish the manner of death, and where the accused's conduct and the surrounding circumstances do not support an inference of guilt, the court must acquit. The judgment emphasizes that speculation and conjecture cannot substitute for proof, and that doubt must be resolved in favour of the accused. It also highlights the importance of proper initial investigation - the police's initial treatment of the matter as sudden death affected the preservation and gathering of evidence that might have clarified the cause of death.
