Michael Tisius is scheduled to be executed in Missouri, USA, on 6 June 2023. He was sentenced to death for two murders committed on 22 June 2000. Now 42 years old, he was 19 at the time of the crime, emerging from a childhood of abuse and neglect. He has been diagnosed with neurological deficits and brain dysfunction, post-traumatic stress disorder and dependent personality disorder. Experts have concluded that an older man exploited Michael Tisius’s immaturity and psychological damage to involve him in the crime. The governor of Missouri should halt the execution and commute his death sentence.
