FAMOUS 1962 ALCATRAZ ESCAPEE WROTE LETTER?

Back in 1962, three inmates famously broke out of Alcatraz prison off the coast of California and disappeared. It was believed they drowned or otherwise met their demise in shark-infested San Francisco Bay. Now, a letter has come to light, allegedly written by one of the three convicts in 2013, which said they all survived their daring escape:
“My name is John Anglin. I escape from Alcatraz in June 1962 with my brother Clarence and Frank Morris. I’m 83 years old and in bad shape. I have cancer. Yes we all made it that night but barely!”
He then offers a deal to the FBI – to be locked up again for a year in exchange for medical care. The three bank robbers were the only known escapees from the island prison, nicknamed “The Rock.” The men used a homemade drill devised from a broken vacuum cleaner motor to widen vents which they crawled through before climbing up a series of pipes. They eventually made it out through the ventilation system that led them to the prison roof and slid down the smokestack to the ground, where they launched a makeshift raft fashioned out of more than 50 raincoats. They also created life vests and wooden paddles. The next morning, shocked guards found dummy heads made of plaster, papier-mâché, paint and real human hair in their cells. According to the letter, Morris died in 2008 and Clarence Anglin died three years later. The letter writer, who would be 86 years old today if this is all true, said he lived in Southern California after spending many years after his escape living in Seattle and North Dakota.
* In fact, he’s been roomies all these years with D.B. Cooper.
* Close one. For a minute there I thought we might have to change the Clint Eastwood movie.
* He closed the letter with “Patrick McGoohan can bite me.”
* Now, let me re-read this whole story in Morgan Freeman’s voice, like in Shawshank Redemption.
* Seattle! Yeesh. Too many hipsters. You can see why he moved to North Dakota.
