Idaho Sheriff's Office Claims It Might Have Solved Infamous 'Tylenol Murders' Case

The Ada County Sheriff’s Office is investigating the possibility that Dr. Mathew Betkouski, who died by suicide in a Boise church in 1982, is connected to the 1982 Tylenol murders. Detective Tim Cooper identified Betkouski through DNA and photos, linking him to a Florida man who disappeared that year. Betkouski, who had worked in drugstores and discussed cyanide use, may be the suspect in the killings where cyanide was substituted for medicine in Tylenol capsules, resulting in seven deaths in the Chicago area.
