On 7 June 2021 at around 1800 hours, the accused (32 years old) and his mother Tshambaja Chuma visited the deceased Henrietta Chuma (44 years old, accused's sister) at her homestead in Chisuma Village, Victoria Falls. They had a discussion about payment of dip tank fees during which the accused and deceased had a misunderstanding - the accused wanted the deceased to pay the fees but she indicated she had no money. The accused and his mother left the homestead. After about 20 minutes, the accused returned armed with an axe. Without saying anything, he struck the deceased once on the head with the axe and fled. The deceased fell to the ground with the axe still embedded in her head and was bleeding from the wound. She was referred to hospital and admitted to the Intensive Care Unit where she died on 27 June 2021. A post mortem report compiled by Dr I. Jekenya at Mpilo Hospital on 29 June 2021 listed the cause of death as brain damage, axe injury and assault by a psychiatric patient.
1. The accused is found not guilty and acquitted by reason of insanity. 2. The accused is hereby returned to prison pending transfer to Mlondolozi Special Institution for further examination and treatment in terms of section 29(2)(a) of the Mental Health Act (Chapter 15:12).
Where an accused person is suffering from a mental disorder at the time of committing an offence to such an extent that he does not appreciate the wrongfulness of his conduct, he cannot be held legally responsible for his actions and the appropriate finding is not guilty by reason of insanity with a special verdict under section 29(2)(a) of the Mental Health Act [Chapter 15:12]. Expert psychiatric evidence is determinative in establishing whether the accused was mentally disordered to the extent that criminal responsibility is negated. Once such mental disorder is established on undisputed evidence, the court must order the accused's detention in a special institution for further examination and treatment in the interests of public safety.
The court noted that the accused was dangerous to society and needed institutional treatment. The measurements and description of the weapon (axe) were recorded in detail, showing the severity of the attack. The court observed that the post mortem report specifically referenced assault by a psychiatric patient, suggesting medical recognition of the accused's mental state at the time of the incident. The fact that both the State and Defence were in agreement regarding the appropriateness of a special verdict facilitated the court's determination.
This case demonstrates the application of the insanity defense in Zimbabwean criminal law and the proper procedure for returning a special verdict under section 29(2)(a) of the Mental Health Act [Chapter 15:12]. It illustrates how mental disorder, specifically schizophrenia or substance-induced psychosis, can negate criminal responsibility even in serious offences such as murder. The case shows the importance of psychiatric evidence in determining criminal capacity and the court's duty to balance public safety concerns with appropriate treatment for mentally disordered offenders through institutional commitment rather than criminal punishment.
