Did serial killer John Wayne Gacy commit other murders still unsolved? Thanks to Cook County (IL) sheriff’s detective Jason Moran, who located evidence vials of Gacy’s blood, some old cold cases may soon be solved. Moran and his department are pursuing an innovative strategy of procuring DNA profiles of Gacy and other executed serial murderers for submission into the national CODIS database. It is hoped that the DNA will match biological evidence from unsolved cold cases, and this will prompt other departments nationwide to submit DNA profiles from those executed in their state as well as DNA evidence from still unsolved cold cases.
An added bonus: Whenever DNA definitively solves a crime, the likelihood of convicting an innocent person is greatly diminished.
