The family of two of the three men who escaped from Alcatraz prison in June 1962 say they have evidence they survived the escape and may actually still be alive today.

Brothers John and Clarence Anglin, along with Frank Morris, escaped the prison by crawling onto the roof through a hole they had chiseled. They made papier-mâché heads with hair they got from the prison barbershop to make it appear their beds were occupied.

Once free, they boarded a raft made from raincoats and headed off the prison island and into San Francisco Bay.

The prison claims the men drowned, which allowed Alcatraz to boast that there have been no successful escapes. But their bodies were never found.

The family says it has photographic proof the brothers were alive into the 1970s, and may still be alive today in Brazil. They would be in their 80s. (NY Post)
