'Unknown Wanderer' identified as Dr. Betkouski may have ties to Tylenol murders
Key Points:
- The "Unknown Wanderer," a man who died of cyanide poisoning in an Idaho church in 1982, has been identified as Dr. Mathew Francis Betkouski, an organic chemist with a history of discussing poisons.
- Investigators found connections between Betkouski and the 1982 Chicago Tylenol murders, where seven people died from cyanide-laced capsules, but they have not named him a suspect due to lack of evidence placing him in Chicago at the time.
- Forensic experts, including Dr. Park Dietz, consider Betkouski a viable suspect based on his background and behavior, though definitive proof of involvement remains elusive.
- Betkouski's identity was confirmed through DNA genealogy after nearly 30 keys and other personal items were traced, revealing his past discussions about cyanide and maps of Chicago among his belongings.
- Authorities continue to investigate Betkouski’s movements in 1982 and have shared their findings with Chicago investigators, indicating the case remains open.
