'Unknown Wanderer' identified as Dr. Betkouski may have ties to Tylenol murders

A mysterious man who died of cyanide poisoning inside an Idaho church more than four decades ago has finally been identified, and investigators say his past raises questions about a possible connection to the still-unsolved 1982 Chicago Tylenol murders. The man known for decades as the "Unknown Wanderer" was Dr. Mathew Francis Betkouski, an organic chemist with a history of discussing cyanide and poison, the Ada County Sheriff's Office in Boise announced Wednesday. Investigators said they couldn't place Betkouski in Chicago during the final week of September 1982, when seven people died after taking Tylenol capsules laced with cyanide, and they are not naming him as a suspect. TYLENOL MURDERS SUSPECT GAVE EERIE FINAL INTERVIEW BEFORE DEATH Dr. Park Dietz, a forensic psychiatrist who was consulted during the original Tylenol investigation and reviewed the evidence gathered on Betkouski, offered a stronger assessment.
