“They decided that they would have to make dummy heads to be in their bunks, in case one of them was not in there when the guard would go by. This was at a time when the lights were turned low, and it would be difficult to recognize other than a face was in the bed.â€
Inmate Leon “Whitey†Thompson was one of the many prisoners who helped the escapees:
“Morris asked me about how you mix flesh tone, ‘cause you see, I am an artist, I did, I did a lot of oil painting on Alcatraz. I begin to wonder, why is he so interested in flesh tone and then I begin to put it all together because uh, they needed a flesh tone color for the dummy heads.â€
The dummies were made from soap, concrete powder, and stolen paint. One of the Anglins worked in the barbershop and swiped some hair to paste on the dummies’ heads for an extra touch of realism.
For eight months, Morris and the Anglin brothers left their cells at night to drill out the ventilation shaft and collect the items they needed for their escape. Clarence Carnes, who saw a lot during his 18 years on the Rock, was impressed by their effort:
In his manuscript, Clarence Carnes wrote, “… many times through the years I‘d met men who had tried to escape. But their flaw had been too little planning and being too hasty. They had not been thorough in their thinking, and that’s what defeated them. But not this time.â€
For the guards on patrol during the Spring of 1962, the countdowns, the routines, the boredom, were no different than any other time. But many inmates knew differently. During the days, right under the gaze of their keepers, they helped the four escapees in their preparations. One of their most important jobs was secretly passing them raincoats.
Working in their cells at night, the four prisoners used the raincoats to make life preservers, which they then stashed in the escape tunnels. In a secret workspace, hidden by blankets, the Anglins and Morris took turns assembling a raft, also out of the pilfered raincoats.
The time to escape finally arrived.
Quietly, the prisoners left their cells for the last time. Immediately, they encountered their first problem...Allen West was unable to slip through the hole in his cell wall. The others were unwilling to wait. Allen West, the original instigator of the plan, was left behind.
Frank Morris and the Anglin brothers safely slipped their cells into the utility corridor. There, they climbed up the heating pipes to the ceiling, popped out the ventilation ducts they’d cut from the ceiling during the past eight months and made their way to the roof. Still undetected, they ran across the roof, and climbed down outside the prison. They headed toward the water.
