On 28 October 2013 at village Muzeziwa, Chief Mkoka, Gokwe South, the accused, aged 31 years, was charged with murdering his brother Siyesaba Sijori and father Phineas Sijori. At around 1500 hours, the accused ran from his homestead behaving like a possessed person, armed with a pick handle and a skei. His brother and father followed to restrain him. At Muzeziwa's homestead, the accused began breaking windows at Philip Washaya's homestead. When the deceased attempted to subdue him, the accused struck his brother on the head with a pick handle and his father on the head with a hoe. Both fell bleeding profusely. Despite attempts to restrain and tie him up, the accused escaped, found the injured deceased in a house, and struck them both several times on the head. Both died instantly from severe head injuries. The accused had a known history of mental illness dating back to 2013. His wife reported that in October 2013 he began behaving strangely, talking about his father showing him evil text messages on his phone. He was psychotic with auditory hallucinations and delusions, believing he had special powers to make rain and was close to the President.
1) Accused is found not guilty by reason of insanity. 2) In terms of section 29(2) of the Mental Health Act [Chapter 15:12] accused is returned to prison for transfer to a mental institution for further care and treatment.
Where there is a reasonable possibility that at the time of committing an offense, an accused was suffering from mental illness or mental defect to such an extent that he could not be held criminally liable for his actions, a special verdict of not guilty by reason of insanity must be entered. The determination of such mental incapacity relies heavily on expert psychiatric evidence, including evidence of the accused's mental state before, during, and after the commission of the offense, any history of mental illness, and psychiatric observations and diagnoses.
The court noted that the accused was found to be a danger to society and required retention in a mental institution. The psychiatric report indicated the accused was psychotic with auditory hallucinations and delusions, including believing he had special powers to make rain and was close to the President. The accused's wife's testimony about his strange behavior in October 2013, including his belief about evil text messages, provided important contextual evidence of his deteriorating mental state around the time of the offenses.
This case demonstrates the application of the insanity defense in Zimbabwean criminal law, particularly in cases involving serious offenses such as murder. It illustrates the court's reliance on expert psychiatric evidence in determining criminal responsibility where mental illness is raised as a defense. The case also shows the operation of section 29(2) of the Mental Health Act [Chapter 15:12], which provides for the detention and treatment of persons found not guilty by reason of insanity, balancing the need to protect society with the need for appropriate treatment of mentally ill offenders.
