The June 1962 Alcatraz escape was an attempt by American criminals Clarence Anglin, John Anglin and Frank Morris to escape Alcatraz Island, one of the United States' most famous prisons. They burrowed out of their cells, climbed a ventilation shaft onto the roof and then climbed down and left the island on a makeshift raft. Despite an extensive search, the men were never heard from again and their fates remain unknown.
