Idaho Identifies 1982 'Unknown Wanderer' as Dr. Betkouski, Raises Tylenol Murders Question
Ada County Sheriff's Office identified the 1982 'Unknown Wanderer' as Dr. Mathew Francis Betkouski, a chemist who died by cyanide suicide in Boise. While evidence suggests a potential link to the unsolved 1982 Chicago Tylenol murders, authorities have not named him a suspect due to lack of proof he was in Chicago during the killings.
