On 9 December 2009, the accused, a 26-year-old male, killed Letwin Muremba, an 18-year-old female, at village Mabodza, Chief Chiwundura, Midlands Province, Zimbabwe. The deceased was doing her laundry at home when a minor misunderstanding occurred after the accused delayed bringing water for the laundry. The accused armed himself with an axe and struck the deceased twice on the head with the cutting edge. He then carried her to his bedroom, placed her on the floor, and proceeded to strike her several times on the head with the axe until her skull was crushed and opened, killing her instantly. The accused locked the door and fled the scene. The deceased's remains were discovered by her husband, Henry Zvoushe, who alerted villagers, leading to the accused's arrest by police who recovered the blood-stained axe. The accused was a known psychiatric patient who had been treated at Ingutsheni Hospital on two occasions (April 1998 to May 1999) for Schizophrenia paranoia. In January 1998, he had escaped from Gokwe Hospital where he was due for treatment after attempting to kill his uncle and set him on fire.
The court returned a special verdict of not guilty by reason of insanity in terms of section 29 of the Mental Health Act [Chapter 5:12]. The accused was ordered to be returned to Hwa Hwa Prison for further care and treatment for his mental condition.
Where an accused person is suffering from a mental disorder at the time of committing an offence and is so affected by that disorder that he cannot be held legally responsible for his actions, a special verdict of not guilty by reason of insanity must be returned under section 29 of the Mental Health Act [Chapter 5:12]. The determination of legal insanity requires expert psychiatric evidence establishing that the accused's mental condition at the time of the offence prevented him from understanding the nature and wrongfulness of his actions or from controlling his conduct.
The court observed that the attack was serious and unprovoked, and that the circumstances supported the submission that the accused must have suffered from some mental disability at the time the crime was committed. The court also noted the accused's dangerous history, including a previous attempted murder in 1998 and the current murder charge in 2000, emphasizing the need for continued mental health treatment and detention to protect society.
This case demonstrates the application of the insanity defence in Zimbabwean criminal law and the importance of psychiatric evidence in determining criminal responsibility. It illustrates the court's approach to cases where the accused has a documented history of severe mental illness (Schizophrenia paranoia) and the proper procedure for returning a special verdict under section 29 of the Mental Health Act. The case also highlights the protective function of the criminal justice system in ensuring that mentally ill offenders receive treatment rather than punishment, while also protecting society from dangerous individuals by ordering their detention for treatment.
