Detective Sgt. Jason Moran of the Cook County Sheriff’s Office stands in the room where evidence from the serial killer John Wayne Gacy murders is kept Wednesday, Dec. 5, 2018, at the Cook County Warehouse in Chicago. Gacy sexually assaulted, tortured and murdered at least 33 teenage boys and young men in Cook County, Illinois between 1972 and 1978 and spent 14 years on death row before he was executed by lethal injection at Stateville Correctional Center in 1994. Since the case reopened in 2010, Moran has helped identify two previously unknown victims, William George Bundy and James Byron Haakenson. Of the 33 total murders, six still remain unidentified.
