A Missouri inmate who fought his death sentence up until the final hour of his life was executed on Tuesday by the state of Missouri. Kevin Johnson, 37, died by lethal injection. He had been sentenced to death in 2005 for murdering Kirkwood Police Sergeant William McEntee as a teenager. A special prosecutor claimed that racial bias infected Johnson’s conviction and judgment. We talk with Riverfront Times staff writer Monica Obradovic about this story.
