THE CASE OF THE UNKNOWN WANDERER
Some cases don't go cold.
They just sit there.
Waiting.
Back in 1982, a man walked into a church in Idaho. Nobody knew who he was. He carried no identification and gave investigators a name that turned out to be fake. In his pockets were nearly $1,900 in cash, almost 30 keys, a distinctive bolo tie and a collection of other clues that, at the time, led detectives nowhere.
The man became known as the “Unknown Wanderer.”
Then he died.
For more than four decades, that was where the case sat.
But detectives aren't particularly good at letting a mystery stay dead.
In 2019, investigators reopened the case. Advances in forensic science eventually gave them something detectives in 1982 simply didn't have: modern DNA and genealogical techniques.
The Unknown Wanderer was finally identified as Dr. Mathew Francis Betkouski.
And that's where this old cold case takes a strange turn.
Investigators discovered evidence suggesting Betkouski may have had a connection to one of the most notorious unsolved crimes in American history: the 1982 Chicago Tylenol murders, in which seven people died after taking capsules laced with cyanide.
Among the evidence were photographs, a hand-drawn map of Chicago and a bottle containing homemade cyanide.
But here's where a good investigator knows better than to jump to conclusions.
Authorities have not established that Betkouski committed the Tylenol murders, and investigators have not been able to place him in Chicago when the poisonings occurred.
So, after 43 years, we still don't have the whole story.
But we have something investigators love almost as much as an answer:
A new lead.
That's the thing about cold cases.
Evidence doesn't always disappear.
Sometimes it just waits for technology to catch up with it.
And somewhere in a box, a database, an old photograph or a forgotten file, there may still be one piece of the puzzle sitting there, waiting for somebody to take another look.
Case closed?
Not quite.
Case reopened.
And that's when the real detective work begins.
