Missouri Governor Mike Parson confirmed Monday that the state of Missouri will carry out the sentence of Ernest Lee Johnson Tuesday as ordered by the Supreme Court of Missouri.

Johnson was convicted for the murder of three people during a robbery in 1994. Evidence showed Johnson went to great lengths to conceal and plan his crime. Three juries have reviewed Johnson’s case and recommended a sentence of death. Johnson’s claim that he is not competent to be executed has been reviewed and rejected by a jury and the courts six different times, including a unanimous decision by the Missouri Supreme Court.
