The only confirmed member was eventually found…dead.

Nearly a century ago, the Denver Mint was robbed in Colorado one morning in a case that remains unsolved to this day.

Mint Job

On December 18, 1922, a day like any other as a Federal Reserve Bank truck sat outside the U.S. Mint in Denver, Colorado. At the time, the guards on duty had just loaded up a total of $200,000 when, at 10:30 a.m., a group of thieves pulled up in a Buick beside the truck.

As later determined, Trainor had sustained injuries during the robbery, and ultimately died during the gang’s escape. Following the discovery of his body, police suspected that Harvey Bailey, whom Trainor had worked with in the past, may have also been a member of the gang in the Mint robbery. However, no evidence was ever found to implicate Bailey in the theft in any capacity.

Then, a little over a month after locating Trainor’s body, on February 17, authorities in Minnesota raided an abandoned hideout, where $80,000 from the theft were…
