10-year Carbondale Police Officer Lenard "Lon" Sizemore was killed on the night of August 20, 1933, at 54. At around 2:20 a.m. Sizemore attempted to arrest Joseph Brinson at "a bootlegging joint" for disturbing the peace when Brinson resisted arrest. Brinson produced a handgun and shot Sizemore to death. A search ensued in less than an hour, bringing the Jackson County Sheriff and his deputies to Carbondale to help locate Brinson. Once Brinson was found, a gunfight between Brinson and the Sheriff's deputies occurred in a cornfield (now the 200 block of East Oak), resulting in Brinson's death.
In 2002 Sizemore's name was added to the Illinois Police Officer Memorial in Springfield, IL, as well as the National Law Enforcement Officers Memorial in Washington, D.C.
