In 1983, Wells Fargo security guard Victor Manuel Gerena pulled off a $7 million heist, tied up his coworkers, and vanished—never to be caught. Allegedly aided by the Puerto Rican nationalist group Los Macheteros, he became one of the FBI’s longest-running fugitives, with rumors placing him in Cuba, Mexico, and beyond. With the money never recovered and no confirmed sightings, his escape remains one of the greatest unsolved mysteries in American crime history.
