What happened to the three men who escaped from Alcatraz? In June 1962, brothers Clarence and John Anglin and Frank Morris attempted to escape from the inescapable water-bound prison, Alcatraz, located on Alcatraz Island in the San Francisco Bay on the coast of California.
They were never seen again, prompting claims that they were the only successful escapees in Alcatraz history. But pieces of a makeshift life vest and a bundle of letters wrapped in rubber were later found, suggesting that the men may have drowned amid the stiff currents and freezing waters of San Francisco Bay.
