Sixty years on from the infamous Alcatraz prison break police have released new age-progressed images of the three escapees believing they could still be alive.
Pictures by a forensic artist of Frank Morris, Clarence Anglin and his brother, John Anglin have been released by the US Marshals Service who are still hunting the men.
If alive, all will be in their 90s today.
The three convicted bank robbers escaped from ‘The Rock’ in June of 1962 by climbing through the prison’s vent systems.
They had spent 18 months preparing for the breakout, digging around a metal air vent in their prison cells, until eventually, they had cleared enough of a hole to pass through it.
They then shimmied up poles to traverse the rooftop and sneak past guards before sliding down 50-feet chimney to the ground of the prison’s shower area.
Once there they made their escape off the island in a makeshift rubber raft that was constructed from raincoats.
To this day, police are unsure if the men survived the treacherous and frigid Bay waters around the prison but have refused to give up the search.
At the time of their disappearance, authorities found pieces of a wooden paddle and a rubber inner tube in the water around Alcatraz after the escape.
They also located a homemade life vest washed up on a nearby beach.
Supervising Deputy Mike Dyke of the U.S. Marshals Service previously said he believed the three men may have survived.
“I think probably the brothers lived ... but there’s a chance that all three of them could have lived and they just split up once they left,” he said.
“There’s no body recovered. I can’t close the case. There’s still a chance.
“You can’t rule out the fact that they died. But you can’t rule out the fact that they lived.”
According to the FBI, Morris, a bank robber and burglar, was sent to Alcatraz in 1960. John Anglin and his brother Clarence arrived not long after.
All three men knew each other from previous prison stays.
Officials describe Morris, who used the pseudonyms Carl Cecil Clark, Frank Laine and Frank Lane, as having a removed tattoo on his forehead, and scars on his left upper arm and left elbow.
He was sentenced to 14 years in prison for a bank heist in Slidell, Louisiana, and federal authorities age-progressed his booking photo to the age of 88 - though he would be 96 if he were still alive.
Clarence, who was sentenced to 15 years in prison for an armed bank robbery in Columbia, Alabama, would be 91 years old today if he is still alive.
His brother, John is described as having a scar on his left cheek, another on his forearm and a third on his forehead.
His photo was age-progressed to 84, but if he were alive, John would be 92 today.
It was the morning of June 12, 1962, that guards discovered the three inmates missing from their beds.
In their place were dummy heads made of plaster, flesh-tone paint and real human hair, the FBI said.
They had used spoons as well as a homemade drill made from the motor of a broken vacuum cleaner to widen the air vents in their cells and squeezed through to a utility corridor, the FBI said.
In 2013, a letter allegedly written by John Anglin was sent to the San Francisco Police Department The author said: “We all made it that night but barely.”
He said his brother died in 2011 and Morris died in 2008.
The letter writer also revealed he was suffering from cancer and said, “If you announce on TV that I will be promised to first go to jail for no more than a year and get medical attention, I will write back to let you know exactly where I am. This is no joke.”
Marshals sent the letter to the FBI for analysis and the results came back inconclusive.
Alcatraz’s famous inmates included Al Capone, George “Machine Gun” Kelly and Robert Stroud, known as the Birdman of Alcatraz.
The prison closed in March 1963 and is now a hugely popular tourist attraction.
