U.S. Marshals still looking for inmates who escaped Alcatraz 60 years ago

The U.S. Marshals Service has shared new age-processed photos of the three men who escaped the infamous prison in 1962.

Sixty years after three men pulled off the escape of a lifetime from Alcatraz, the U.S. Marshals Service has released images of what they think the criminals may look like now.

Frank Morris, along with brothers Clarence and John Anglin, escaped from the infamous island penitentiary in 1962, tunneling their way out of the prison before using a rubber life raft they fashioned out of World War Two-era raincoats to sail away.

Guards investigating the escape at the time found dummy heads fashioned out of plaster, skin-toned paint and real human hair in the men’s beds.

The case went on to inspire the 1979 film Escape from Alcatraz, and to this day the three fugitives have never been found.

The U.S. Federal Bureau of Investigation (FBI) worked on the case for 17 years before officially closing the file in December of 1979 and turning it over to the U.S. Marshals Service.

At the time, the FBI said there was “no credible evidence” to suggest the men were still living.

In an effort to solve the case once and for all, three age-progressed photos were released this month showing what each man could look like now. The men, who were all incarcerated for bank robbery, would be in their 90s today.

It’s been speculated that the trio could have drowned in their escape attempt, given the choppy, cold waters of San Francisco Bay. However, Supervising Deputy Mike Dyke of the U.S. Marshals Service told CBS News in 2011 that he thinks they likely survived.
