Documented Alcatraz Escape Evidence
In June 1962, inmates Frank Morris and brothers John and Clarence Anglin vanished from Alcatraz Island. Investigators later found a raft made from raincoats, dummy heads, and a makeshift paddle. Physical evidence recovered from the water and shoreline included personal items and fragments linked to the escapees.
Forensic Analysis and Official Findings
The FBI concluded the escapees likely drowned in the cold, strong currents of San Francisco Bay. Forensic reviews of the raft and personal belongings supported this assessment. The U.S. Marshals Service case file remains open, and officials continue to evaluate new Alcatraz escape evidence as it emerges.
Legacy of the 1962 Prison Break
The case remains one of the most studied unsolved federal cases. Researchers have re-examined evidence using modern forensic methods and reviewed historical records. The National Park Service, which manages the site, notes the escape attempt as a key part of Alcatraz history.
