In 1962, inmates Frank Morris and Allen West hatched a plan with the Anglin brothers to get out of their cells and off the island, using the ventilation shafts under their sinks. They’d crawl into the shaft, up behind the cell walls and onto the roof.

After 8 months, their escape plan was ready. They placed dummy heads made of sop and concrete in their beds, and made it outside. Then they inflated a raft made up of raincoats and headed out into the SF Bay. Authorities began a manhunt, and found personal effects, but never the missing men. The case was closed in 1979, with no sign of any of them. They just… disappeared.
