On September 19, 1910, a prowler broke into the home of Clarence Hiller in the Chicago neighborhood Morgan Park. When he awoke Hiller’s 13-year-old daughter, pandemonium erupted and before it was over, Hiller lay dead at the bottom of the stairs. In breaking into the house, Thomas Jennings left his left palm print in a freshly-painted porch rail. Those prints would be the first ever admitted into evidence. The case changed police standard practices across the nation and around the world. In “The First Fingerprint Trial,” True Crime Historian Richard O Jones tells the story.
