Joyce LePage vanished from a Washington State University dorm in 1971; investigators developed six suspects including her meditation group, a volatile ex-boyfriend, and her roommate, but 55 years later her killer remains free. Deep dive into letters, polygraphs, and suspicious behavior reveals new leads and a $100,000 reward still unclaimed. Joyce's handwritten letter to her boyfriend revealed Mark Wadley had stayed at a mental institution for trying to strangle people—a critical detail never pursued by investigators despite raising major red flags.
