context_page_description: The Alcatraz Federal Penitentiary or United States Penitentiary, Alcatraz Island was a maximum security federal prison on Alcatraz Island, 1.25 miles off the coast of San Francisco, California, United States, the site of a fort since the 1850s; the main prison building was built in 1910–1912 as a United States Army military prison. The United States Department of Justice acquired the United States Disciplinary Barracks, Pacific Branch, on Alcatraz on 12 October 1933, and the island became a prison of the Federal Bureau of Prisons in August 1934 after the buildings were modernized and security increased. Given this high security and the island's location in the cold waters and strong currents of San Francisco Bay, prison operators believed Alcatraz to be escape-proof and America's strongest prison.
  The three-story cellhouse included the four main cell blocks, A-block through D-block, the warden's office, visitation room, the library, and the barber shop. The prison cells typically measured 9 feet by 5 feet and 7 feet high. The cells were primitive and lacked privacy, with a bed, desk, and washbasin, and a toilet on the back wall, and with few furnishings except a blanket.
context_section_description: On 11 June 1962, Frank Morris, John Anglin, and Clarence Anglin, in contrast, attempted to escape using careful planning. Behind their cells in Cell Block B was an unguarded 3-foot (0.91 m) wide utility corridor. The prisoners chiseled away the salt-damaged concrete from around an air vent leading to this corridor, using tools such as a metal spoon soldered with silver from a dime and an electric drill improvised from a stolen vacuum cleaner motor. The noise was disguised by accordions played during music hour, and the progress was concealed by false walls which, in the dark recesses of the cells, fooled the guards.
  The escape route led up through a fan vent; the prisoners removed the fan and motor, replacing them with a steel grill and leaving a shaft large enough for a prisoner to enter. Stealing a carborundum abrasive cord from the prison workshop, the prisoners then removed the rivets from the grill. In their beds, they placed papier-mâché dummies made with human hair stolen from the barbershop. The escapees also made an inflatable raft over many weeks from over 50 stolen raincoats, which they prepared on the top of the cell block, concealed from the guards by sheets which had been put up over the sides. They escaped through a vent in the roof and departed Alcatraz.
  The FBI investigation was aided by another prisoner, Allen West, who was part of the escapees' group but was left behind. West's false wall kept slipping so he held it in place with cement, which set. When Morris and the Anglins accelerated the schedule, West desperately chipped away at the wall, but by the time he got out, his companions were gone. Hundreds of leads and theories have been pursued by the FBI and local law enforcement officials in the ensuing years, but no conclusive evidence has ever surfaced favoring the success or failure of the attempt. The FBI's investigation from 1962 to December 1979 was finally treated as closed. The official report on the escape concludes that the prisoners drowned in the cold waters of the bay while trying to reach the mainland, it being unlikely that they made it the 1.25 miles to shore due to the strong ocean currents and the cold sea water temperatures ranging between 50 to 55 °F (10 to 13 °C).
  The U.S. Marshals Service case file remains open and active, however. Morris and the Anglin brothers remain on its wanted list. Circumstantial evidence uncovered in the early-2010s seemed to suggest that the men had survived, and that contrary to the official FBI report of the escapee's raft never being recovered and no car thefts being reported, a raft was discovered on nearby Angel Island with footprints leading away, and a 1955 blue Chevrolet had been stolen on the night of the escape by three men, who could have been Morris and the Anglins, and that officials then engaged in a cover-up. Relatives of the Anglin brothers presented further circumstantial evidence in the mid-2010s in support of a longstanding rumor that the Anglin brothers had fled to Brazil following the escape; a facial recognition analyst concluded that the one piece of physical evidence, a 1975 photograph of two men resembling John and Clarence Anglin, did support that conclusion.
