Document 3: Bernard Coy: Coy was a native of Kentucky who turned to crime during the Great Depression and, in 1937, was sentenced to 25 years imprisonment. He was transferred to Alcatraz from Atlanta in 1938 and was later given the position of cell-house orderly which allowed him access through most of the main cell-block on Alcatraz. This relative freedom allowed him to spot a tiny flaw in one of the prison's security features, the bars of the gun-gallery overlooking the cell house. Coy along with Joe Cretzer, Marvin Hubbard, Sam Shockley, Miran Thompson, and Clarence Carnes planned to break into the gun galleries to steal weapons, take hostages and then flee to the dock. He was successful in creating a makeshift bar-spreader that enabled him to get through the relatively weak bars that protected the gun galleries and overpower the unsuspecting guard on his return from investigating a fabricated incident caused by Shockley in the prison's secure unit, D-Block.
