Charles Thomas Walker (April 28, 1940 – September 12, 1990) was an American convicted murderer who was executed in 1990 by the state of Illinois for the June 1983 murders of Kevin Paule, 21, and his fiancée Sharon Winker, 25, of Mascoutah. Looking for beer money, Walker robbed them of $40 and shot them to death while the couple fished in a St. Clair County creek. He was executed by lethal injection at Stateville Correctional Center at the age of 50, becoming the first person to be executed in Illinois since 1962. The execution was considered botched because the lethal injection machine was unable to make the drugs go through the kinked lines.
