Thanks to recent DNA technology, a previously unidentified John Wayne Gacy victim is no longer anonymous. The Cook County Sheriff’s office matched the remains found in Gacy’s crawlspace to a 19-year-old who went missing in 1976 on his way to a party, William George Bundy, the Chicago Tribune reports. Bundy’s sister says she always suspected Gacy killed her brother, because he often ensnared victims through his construction company, and Bundy worked construction jobs. Eight other Gacy victims remain unidentified. (Click for one suspected Gacy victim who turned up alive.)
