The State of Missouri is set to execute Kevin Johnson on 29 November 2022. He was sentenced to death in 2007 for the murder of a police officer in 2005. Kevin Johnson, aged 19 at the time of the crime, had experienced a lifetime of deprivation and sexual and physical abuse. The crime occurred hours after the sudden death of his younger brother. Despite Kevin Johnson’s history of psychiatric disorders, the jurors never heard any expert testimony of the effect of his brother’s death or his own traumatic history and mental disabilities when they decided whether to spare his life.
