Pieces of a homemade raft. Paddle-like wooden pieces. And a makeshift life preserver.
But no confirmed trace of the three men.
The FBI investigated for 17 years before closing its case in 1979. The U.S. Marshals Service took over responsibility, and the men's whereabouts remain unknown.
Investigators believed the freezing water and strong currents made survival unlikely.
But they never proved that the men drowned.
So what do you think?
Did they die trying to escapeโฆ or did they pull off the impossible and disappear for good?
They had another plan.
The men used more than 50 raincoats to make a makeshift raft and life preservers. They also made wooden paddles.
On the night of June 11, 1962, three men slipped out through the ventilation route, reached the prison roof, climbed down, and made their way to the shore.
Then they launched their homemade raft into the dark waters of San Francisco Bay.
The next morning, the guards discovered the empty beds.
But when investigators searched the water, they found somethingโฆ
The plan was more elaborate than anyone expected.
Frank Morris and brothers John and Clarence Anglin spent months secretly widening the vents in their cells with crude homemade tools.
They even built fake heads using plaster, paint, and real human hair.
At night, the heads lay in their beds while the real prisoners worked on their escape.
And they weren't planning to swim across the bay with nothing but their bare handsโฆ
In 1962, three prisoners escaped from Alcatraz, one of America's most infamous prisons.
They left fake heads in their beds to fool the guards.
By morning, they were gone.
But here's the strangest partโฆ
They may have escaped the prison. But did they survive what came next? โ ๏ธ
