Three prisoners escaped from Alcatraz on June 11, 1962. They made dummy heads from soap, cement, and paint, fooling the guards for one night. After climbing the utility corridor to the roof and sliding down an outside stove pipe, they crept to the shoreline. As they faced the icy bay waters, the men may have wished they could swim like salmon; apparently they fashioned a raft out of a raincoat. The men were never seen again, but there were hints that at least two of them made it to South America.
