The Missouri Supreme Court has refused to overturn the conviction of Kenneth Baumruk, who was sentenced to die for killing his wife and wounding four others in a 1992 St. Louis County Courthouse shooting rampage.
It wasn't clear if the Missouri Attorney General's office would seek an execution date following the ruling on Tuesday. A spokeswoman declined comment. Baumruk's attorney did not return a message seeking comment.
At 73, Baumruk is the oldest man on Missouri's Death Row.
