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, who escaped from prison while serving a life sentence for murder, also shot and killed Butte County Sheriff Dave Malcolm near Spearfish, on January 24, 1946.
Sitts had pleaded guilty to second degree murder in Minnesota for the December 12, 1945, slaying of Erik Johansson, a liquor store clerk, during a botched robbery.
After the slayings of Matthews and Malcolm, Sitts fled to Wyoming, where he was arrested on February 5, 1946, and returned to South Dakota.
"This is the first time authorities helped me escape prison," he said right before the four shocks surged through his body at 12:15 a.m. Special Agent Matthews name is inscribed on Panel 34 of the National Law Enforcement Officers Memorial located on Judiciary Square, Washington, D.C. Sheriff Malcolm's name is inscribed on Panel 53.
