Wanted poster for a mail train robbery
Wanted poster for 1923 mail train robbery

In 1923 brothers Hugh, Ray and Roy DeAutremont tried to rob a mail train. This wanted poster shows the train car after they destroyed it by using too much dynamite. The brothers killed four men during the robbery. The manhunt distributed wanted posters for the trio across the U.S. and even abroad. They were finally brought to justice in 1927.
