June 11, 1962 Frank Morris and brothers John and Clarence Anglin vanished from their cells and were never seen again. A fourth man, Allen West, believed by some people to have been the mastermind, was also involved; however, he was still in his cell the next morning when the escape was discovered.
An investigation revealed an intricate escape plot that involved homemade drills to enlarge vent holes, false wall segments, and realistic dummy heads (complete with human hair) placed in the beds so the inmates would not be missed during nighttime counts. The three men exited through vent holes located in the rear wall of their cell - they had enlargened the vent holes and made false vent/wall segments to conceal their work. Behind the rear wall of the cells is a utility corridor that had locked steel doors at either end. The three men climbed the utility pipes to the top of the cellblock, and gained access to the roof through an air vent (the men had previously bent the iron bars that blocked the air vent). They then climbed down a drainpipe on the northern end of the cellhouse and made their way to the water. It is believed they left from the northeast side of the island near the powerhouse/quartermaster building. They used prison-issued raincoats to make crude life vests and a pontoon-type raft to assist in their swim. A cellhouse search turned up the drills, heads, wall segments, and other tools, while the water search found two life vests (one in the bay, the other outside the Golden Gate), oars, and letters and photographs belonging to the Anglins that had been carefully wrapped to be watertight. But no sign of the men was found.
This is what is so funny about this story half is right The men did make it off the Rock and I know this because they sent a postcard back to the other guys there and one of the guys there was My FATHER
