On the morning of June 12, 1962, a guard on the 7:15 head count at Alcatraz Federal Penitentiary pulled back a blanket in cell 138 and found himself staring into a face that wasn’t breathing. It was papier-mâché, painted with real hair swept from the prison barbershop, molded with soap and toilet paper into a passable likeness of inmate Frank Morris. Two cells away, the same trick had bought John and Clarence Anglin roughly nine extra hours. By the time the alarm sounded, all three men — along with a raft cobbled from more than fifty raincoats — were gone, and “The Rock,” a prison the federal government had built specifically because escape was supposed to be impossible, had just suffered the only breakout in its history that was never definitively solved.

Six Months of Spoons and Vacuum-Cleaner Motors

Frank Morris, a career bank robber and burglar with a measured IQ reportedly in the 130s, arrived at Alcatraz in January 1960 after a string of escapes from lesser prisons made him too much of a flight risk anywhere else. He was soon joined by brothers John and Clarence Anglin, both convicted for bank robbery, and a fourth conspirator, Allen West, whose cell renovation fell behind schedule and who was left behind on the night of the escape. Working over roughly six months, the men used spoons stolen from the dining hall, scavenged scrap metal, and a motor pulled from a stolen vacuum cleaner to drill through the crumbling concrete around the ventilation grilles at the back of their cells — concrete so degraded by damp sea air that the digging could be masked by an accordion player rehearsing nearby. Behind the grilles lay an unguarded utility corridor that led to the roof.

The Raft, the Bay, and the Vanishing

From the roof, the three men descended to the shoreline and inflated a raft and life vests they had fashioned from more than fifty stolen prison raincoats, glued at the seams and sealed using heat from a make-do steam vent. Sometime after 10 p.m. on June 11, they slipped into San Francisco Bay’s frigid, fast-moving water and paddled into the dark, aiming for Angel Island roughly a mile and a half away. They were never seen again — at least not verifiably. A search involving the FBI, Coast Guard, and Bureau of Prisons combed the bay and surrounding shorelines for weeks. Investigators recovered a homemade paddle and pieces of rubber inner tube in the water, along with a packet of letters wrapped in rubber that belonged to the Anglins, found floating near the bay entrance — but no bodies, then or ever.

The FBI’s Verdict Versus an Open File

In 1979, after 17 years of investigation, the FBI officially closed its file, concluding on the balance of circumstantial evidence and expert opinion that the men most likely drowned attempting the crossing in cold, powerful currents. The U.S. Marshals Service, however, never formally closed its case, and Morris and the Anglin brothers technically remain on its wanted list — their file set to stay open, by federal statute governing such matters, until the men would turn 99 years old around September 2026, unless definitively proven dead beforehand. That open status has kept the case alive as one of the FBI’s most enduring unsolved mysteries, discussed on the Bureau’s own “famous cases” history pages alongside Al Capone and D.B. Cooper.

A Letter, a Photograph, and Family Claims

The most tantalizing wrinkle surfaced in 2013, when the San Francisco Police Department received a handwritten letter purportedly from John Anglin, claiming that he had survived the crossing, that Frank Morris had died in 2008, and that Clarence Anglin had died in 2011 — and offering to turn himself in in exchange for leniency due to failing health. The FBI ran the letter through forensic handwriting analysis and searched it for fingerprints and DNA; the results were ultimately inconclusive, neither confirming nor ruling out its authenticity. Separately, relatives of the Anglin brothers have long maintained that the two attended their mother’s funeral in 1962 and later family funerals in the 1970s and 1980s disguised as women, and a photograph surfaced decades ago allegedly showing the brothers alive in Brazil in the 1970s, which forensic facial-recognition analysts commissioned by a History Channel investigation described as showing “compelling” — though not conclusive — similarities.

Testing the Physics, Six Decades Later

The question of whether the crossing was even survivable has drawn engineers as well as historians. In November 2025, YouTube creator Mark Rober, working with journalists Johnny Harris and Cleo Abram, built a period-accurate raft using the same raincoat-and-glue method described in the original FBI reports and tested it in the bay under similar tidal conditions. Their recreation reached open water near the Golden Gate Bridge rather than sinking or drowning its occupants, lending fresh circumstantial support to the theory that a well-timed departure could plausibly have gotten the men across alive — though it proved feasibility, not what actually happened that night in 1962.

Why This Case Still Matters

The Alcatraz escape endures because it sits at the exact midpoint between the impossible and the plausible. The prison was designed and marketed as escape-proof, its cold currents assumed to be as effective a wall as any fence; the fact that three ordinary men very nearly proved that wrong — using little more than spoons, soap, and stolen raincoats — has made it one of the defining stories of ingenuity in American criminal history. It also remains a rare case where the U.S. government’s own position is genuinely unresolved: the FBI’s working theory is death by drowning, but the file that would prove it has never been closed.

An Anniversary Still to Come

When the U.S. Marshals’ wanted file finally lapses in September 2026, it will mark the formal end of a manhunt that has run longer than most of the men chasing it have been alive — and yet no bones, no death certificate, and no confirmed sighting has ever definitively closed the story. If Frank Morris and the Anglin brothers really did make it to that far shore in the dark, what became of the rest of their lives?
