Example of a Case Appropriate for the M’Naghten Insanity Defense

17 February, 2016 - 11:05

Andrea, a diagnosed schizophrenic, drowns five of her young children in the bathtub. Andrea promptly phones 911 and tells the operator that her children are dead. The operator dispatches an emergency call to law enforcement. When law enforcement officers arrive at Andrea’s house, she informs them that she killed her children so that they could leave this earth and enter heaven.

Andrea thereafter claims she is not guilty for killing her children by reason of insanity. Andrea could be successful if the jurisdiction in which she killed her children recognizes the M’Naghten insanity defense. Andrea suffers from a mental defect, schizophrenia. In addition, there is no evidence indicating Andrea knew her conduct was wrong, such as an attempted escape, or cover-up. In fact, Andrea herself contacted law enforcement and immediately told them about her criminal acts. Thus both of the M’Naghten elements appear to be present, and Andrea’s conduct may be excusable under the circumstances.
