The ’Unknown Wanderer’ finally gets a name — and it revives the Tylenol murders mystery

In 1982 a man died of cyanide poisoning in a Boise church with no ID — the Unsolved Mysteries ’Unknown Wanderer’. Ada County has now identified him by DNA as Dr. Mathew Francis Betkouski, an organic chemist.

Why a name matters, even decades later

An unidentified person is an unfinished story for family, investigators, and the historical record. Modern DNA work and genetic genealogy can connect remains to relatives even when fingerprints and dental records could not. Here, identification gives the man who died in Boise in 1982 his name back. It answers one question — who he was — while leaving separate questions about the wider case for evidence, not speculation.

What to do, step by step

1. Separate what is confirmed: Ada County identified the man by DNA as Dr. Mathew Francis Betkouski.
2. Keep the identification distinct from any claimed link to other cases or events.
3. Check who is speaking — a coroner's office identification carries more weight than commentary.
4. Notice how DNA identification works: matches point to relatives, then records confirm identity.
5. Treat revived theories about old cases as unproven until investigators say otherwise.
