Idaho Case May Be Connected to the 1982 Tylenol Murders, Officials Say
Investigators say the man was carrying 19 $100 bills and a suicide note, and they plan to outline a possible link to the unsolved Tylenol deaths.
- On Wednesday, the Ada County Sheriff's Office identified the man known for decades as the "Unknown Wanderer" as Dr. Mathew Francis Betkouski, an organic chemist who died by suicide in a Boise church in 1982.
- The announcement explores a potential link between Betkouski and the 1982 Tylenol murders that killed seven people in the Chicago area, a poisoning spree that spurred nationwide panic and led to tamper-evident medication packaging.
- Ada County Cold Case Detective Tim Cooper described Betkouski as a "brilliant man" with a documented fascination with chemistry, and coworkers reported he discussed how cyanide could be used to commit the "perfect crime."
- While investigators are not naming Betkouski as a formal suspect in the Tylenol homicides, they have shared their findings with Chicago police to generate new leads regarding his whereabouts in 1982.
- Sheriff Matt Clifford and representatives from Unsolved Mysteries announced the case will be featured in the upcoming documentary Unmasking the Tylenol Killer, premiering October 9, 2026, on The Roku Channel.
