The Tulsa World spent a year producing a six-part narrative on what remains perhaps the state's most infamous cold case: the unsolved murders of three girls - Lori Farmer, Denise Milner and Michele Guse - at a Girl Scout camp near Locust Grove 40 years ago. After an intense manhunt, Gene Leroy Hart was arrested and charged with the crimes, but was ultimately acquitted after a sensational trial. The series examines the details of what happened and the lingering effects on those who survived.
