On Halloween night in 1974, eight-year-old Timothy O’Brien came home from trick-or-treating in Deer Park, Texas, excited to sample his candy haul. Among the treats was a Pixy Stix — one that would become infamous in American true crime history. Within hours, Timothy was dead, poisoned by cyanide. Investigators soon discovered that the killer wasn’t a mysterious stranger slipping poison into Halloween candy. It was someone much closer to home — his own father, Ronald Clark O’Brien. His crime forever changed the way parents across the United States viewed Halloween, giving rise to decades of fear over tampered sweets. Books: Read collections of The Evidence Locker Files , available in print and digital editions.
