In June 1962, three inmates—Frank Morris and brothers John and Clarence Anglin—carried out the most famous prison break in American history.

Locked inside Alcatraz, long considered “escape-proof,” they spent months digging holes in their cells with makeshift tools, crafting lifelike dummy heads, and plotting their escape in secret.

Their most daring creation was a raft and life vests fashioned from stolen raincoats. On the night of June 11, they slipped out through ventilation shafts, climbed onto the roof, and vanished into San Francisco Bay.

By morning, chaos erupted. The dummy heads fooled the guards, the raft was gone, and the men had disappeared. The FBI launched an intense manhunt, scouring the waters and coastline. Authorities eventually concluded the prisoners had drowned in the bay’s frigid currents.

Yet, the story refused to fade. Over the years, evidence emerged suggesting survival. In 2013, a letter surfaced, allegedly from John Anglin, claiming all three had lived under false identities. Though handwriting analysis was inconclusive, the possibility of survival reignited debate.

Rumors swirled, fueled by photographs said to show the Anglin brothers living in Brazil. In 2003, MythBusters demonstrated that a raft like theirs could indeed cross the bay, adding weight to the theory.

In 2018, researchers applied AI facial recognition to a 1975 photo from Brazil. The results showed striking similarities between the men in the image and the Anglin brothers, suggesting the escape may have succeeded.

Whether the three drowned or found freedom, the Alcatraz breakout remains an enduring mystery. It is a tale of ingenuity, determination, and the unrelenting human drive for freedom—even from the most “escape-proof” prison.
