The State v Nkulumeko Moyo

The accused was charged with murder under section 47 of the Criminal Law (Codification and Reform) Act. On 14 March 2011, at a bushy area in Victoria Falls, the accused allegedly took the minor child Sharon Sibanda from her home and killed her by crushing her head with a stone at a bushy area between Chinotimba and Zambezi River gorges. A post-mortem report by Dr. Castellanos gave the cause of death as depressed skull fracture, head injury, and assault. The accused tendered a defence outline pleading not guilty to murder by reason of insanity. Dr. Poskotchinova prepared a psychiatric report stating that the accused suffers from psychosis, was not stable at the time of the crime, has a history of abnormalities and epilepsy, and drug abuse. She concluded there was a reasonable possibility the accused was suffering from a mental disorder at the time of the alleged crime.

• Whether the accused was criminally responsible for the murder given his mental state at the time of the commission of the offence
• Whether a special verdict should be returned under section 29 of the Mental Health Act based on the psychiatric evidence

The court returned a special verdict in terms of section 29 of the Mental Health Act [Chapter 15:12]. The accused was committed to Mlondolozi Mental Prison as he was deemed a danger to society.

Where an accused person is charged with a criminal offence and credible psychiatric evidence establishes that at the time of commission of the alleged crime there was a reasonable possibility that the accused was suffering from a mental disorder such that they were not mentally stable, and the State accepts the plea of insanity, the court must return a special verdict in terms of section 29 of the Mental Health Act. Where such a person is found to be a danger to society, commitment to a mental health institution is appropriate.

The court noted that the State "properly accepted" the plea of insanity based on the psychiatrist's report, suggesting judicial approval of the State's approach in recognizing clear psychiatric evidence of mental incapacity. The judgment also implicitly recognizes that persons with mental disorders who commit serious offences require specialized institutional care rather than punishment through the ordinary criminal justice system.

This case demonstrates the application of the insanity defence in Zimbabwean criminal law and the procedural framework for dealing with accused persons who lack criminal capacity due to mental illness. It illustrates the court's approach to psychiatric evidence and the protective measures available under the Mental Health Act, including commitment to a mental health facility rather than conviction and imprisonment. The case shows the acceptance by the State of psychiatric evidence and the court's duty to return a special verdict where mental incapacity is established.
