"The FBI Hid This Letter for 5 Years. It Changes Everything About the Alcatraz Escape."

On June 11, 1962, three men carved through the walls of the world's most secure prison using spoons. They were never found. The FBI said they drowned. They were wrong. In 2013, a handwritten letter arrived at the San Francisco Police Department. It was signed by John Anglin. The FBI classified it for five years. In 2025, a scientific recreation proved the escape route was physically possible. In September 2026, the U.S. Marshals Service closes the case forever — whether the men are found or not. This is the full investigation. Everything the FBI found, everything they buried, and everything that doesn't add up.
