These brothers were both sent to Alcatraz following a bank robbery and attempted escapes from other prisons. Once there, they planned an escape and used spoons and saw blades to burrow into the cement near the back of their cells. They constructed a raft using raincoats and on June 11, 1962, the brothers along with fellow inmate Frank Morris made their way to the bay. This is the last place they were seen. While it’s unlikely that they survived the frigid cold weather of the water, there are legends of their escape survival even today.
