One of the prison’s most fascinating stories is the 1962 escape involving Frank Morris and the Anglin brothers. The trio spent months digging through the walls of their cells using spoons and a homemade drill. They crafted dummy heads from soap, toilet paper, and hair to fool guards during bed checks. On the night of June 11, they escaped through a utility corridor and launched a raft made from 50 rubber raincoats. Despite an extensive manhunt, they were never found. The FBI closed the case in 1979, presuming they drowned, but speculation remains. In 2013, a letter allegedly from one of the escapees surfaced, renewing interest in the case.
