It has been more than 50 years since Frank Morris and the Anglin Brothers escaped from Alcatraz Federal Penitentiary. Because no evidence of the escapees' survival or death has ever emerged, the U.S. Marshals have kept an ongoing search for the men ever since their disappearance. The posters above are the last known pictures and statistics about the men and their projected aging processes. The warrant for all three men’s arrest will expire on their 100th birthdays, but until then, the hunt is on.
