George Sidney Sitts (October 29, 1913 – April 8, 1947) was a convicted murderer who was executed by South Dakota for killing state Division of Criminal Investigation special agent Tom Matthews, who was attempting to arrest Sitts on a fugitive warrant from Minnesota. Sitts was the only person to die in South Dakota's electric chair, and it would be over 60 years until the next time South Dakota would carry out an execution — Elijah Page via lethal injection on July 11, 2007.
