He volunteered that when he had gotten out of the Treatment Unit about May 5, 1961, he had started thinking of ways to break out of Alcatraz. While painting the cellhouse, he noticed the ventilator pipe to the roof from on top of the cell block and thought of it as a possible escape route. He talked over escaping with the two ANGLIN brothers who were also inmates. He read Civil Engineering books in the prison hospital as to how one could break down cement, etc. He said they made small holes in the cement next to the ventilator grille at the back part of their cells by using sharpened spoon handles and soap. He had practically finished his hole on April 25, 1962. They made cardboard frames and painted them to match the walls in their cells and inserted them after they had removed part of the wall. They hid their working tools behind these false frames. JOHN ANGLIN got through his hole first and got into the utility corridor containing the plumbing fixtures which is located behind the cells. JOHN then helped CLARENCE complete his hole. FRANK MORRIS, Reg. No. 1441-AZ, had joined this venture in December of 1961, and was more or less partner in it.
