Many fans may have the impression that in the classic movie "The Shawshank Redemption", the protagonist Andy successfully escaped from prison by digging out a secret passage with a small stone hammer hidden in the book.
In reality, there is also a well-known prison escape, in which three prisoners work together to escape the most heavily supervised and terrifying prison in the United States, Alcatraz Island.
60 years later, their whereabouts are still unknown.
And this escape from prison has also become the biggest unsolved mystery in the legend of American prisons.
When Jim first set foot on Alcatraz in 1960, he was both nervous and excited.
In the days that followed, he would serve as a prison guard against some of the world's most notorious criminals.
"Almost every American boy grew up listening to the stories of Alcatraz."
Jim was no exception, and the environment here was as eerie as the stories he had heard.
Alcatraz Island is located in san francisco bay, surrounded by cold and bone-chilling waters and lurking sharks.
In case you accidentally fall, there is almost no chance of survival.
The island's federal prisons are heavily guarded, with doors and windows fixed with iron bars, and an average of 3 guards guard a criminal, and it is as difficult as ascending to the sky if they want to escape from prison.
A double hell-level barrier, even if a bird is locked in, it is difficult to escape.
However, even with the best security in the United States, riots and crimes continue to play out in this prison.
Because the criminals held here are full of evil.
Nicknamed "Scarface," Al Capone is the number one person in American crime history.
In the 1920s, he was the big brother of the Chicago Mafia, ran the drug business throughout Chicago, and was once known as the "underground mayor."
What made him "world-famous" was a massacre that caused a sensation in the country.
On Valentine's Day in 1929, he directed his men to disguise themselves as policemen and tricked his sworn enemy Moran into a garage and shot them en masse.
After the news broke, the nation was shocked, and the Chicago Crime Commission imprisoned him in Atlanta Prison.
However, in prison, he not only did not restrain himself, but also accepted a group of prisoners as younger brothers, and his subordinates outside the prison were even more rampant, planning countless prison robberies.
The intolerable federal government had no choice but to transfer him to Alcatraz Island, where Scarface received the highest level of caretaker treatment
He was held in a single cell, surrounded by a dozen guards armed with submachine guns whenever he let the wind blow outside.
During the seven months he was imprisoned, the mafia continued to stir up trouble, attacking police, and in order to quell the unrest, the U.S. government had to let him out of here.
Unexpectedly, after his release from prison, he did not return to his old business, but washed his hands in the golden basin.
Some people say that he suffered from an incurable disease, but the most widely spread theory is that the horror and perversion of Alcatraz island left a psychological shadow on him.
Prison guard DeVincenzi is rumored to have witnessed a prisoner kill another naked inmate in the bathroom because the latter did not grant his request for sexual intercourse.
Such vicious incidents, often staged on Alcatraz Island, coupled with the addition of fuel and vinegar by the media, make this place a frightening "hell on earth".
According to statistics, from 1933 to 1962, there were a total of 13 prison escapes on Alcatraz;
Of these, 23 were caught while fleeing, 6 were shot, 2 were missing, and none of the felons managed to escape.
It wasn't until 1962 that four prisoners had a seamless escape plan.
The Anglin brothers were repeat offenders who were arrested for robbing banks and imprisoned on Alcatraz Island for several attempts to escape from prison.
At Alcatraz, they meet Frank.
The criminal was imprisoned for drug possession and armed robbery, and was rumored to have a superior IQ, and was imprisoned in Alcatraz Prison for a number of felonies.
Another member, Alan, was transferred to Alcatraz after a failed escape from Florida for car theft.
The four hit it off in prison, and the prison escape gang led by Frank was officially formed.
At first, because the cell was too far away to move, the four of them proposed to the prison to move to a district as neighbors.
It stands to reason that prisons hearing such demands must have suspected their motives.
But perhaps the prison authorities were so confident in security that they agreed to the request.
After the four of them moved together, they looked around the cell and felt that the vents under the sink were the most likely passages to escape.
So they planned to dig up and climb out of here.
The path is determined, what to dig for?
There were only a few tools available in prison, and they kept their eyes on the most inconspicuous spoons.
Using stolen spoons, coins, nail clippers, etc., they managed to dig out a passage for only one person to pass, and used cardboard as a cover to avoid the passage opening being discovered by the prison guards.
But even if you walk out of prison, you are surrounded by cold sea water and ambushed sharks, and no matter how good the water is, you will most likely be buried at the bottom of the sea.
They usually collect rubber raincoats everywhere, heat seal them with steam pipes, and make inflatable valves and life jackets.
Every night the prison guards will check the room, and if the person is found to be absent or something abnormal, the escape plan will fail.
The four men made a dummy head out of toothpaste, soap, toilet paper and other materials.
In order to make the head look more realistic, they even went to the prison barbershop to steal the hair paste on it, and it was difficult to distinguish between true and false from a distance.
When everything was ready, they decided to act.
One night, after the lights went out in prison, the four men took out prepared dummy heads, disguised themselves as adults to sleep on them with quilts, and then drilled out of the hole through the passage.
After climbing out of the prison, they sat on the inflatable valves prepared in advance and disappeared into the sea.
Early the next morning, when the prison guards were checking the room, they found that things were not good, and at the same time, it was found that Alan, who had failed to escape from prison, was also discovered.
It turned out that he was stuck when he climbed out of the cave, and he had a hard time climbing out, but found that his accomplices had already left him and left, and he had to return the same way.
From Allen's testimony, the police learned that the cunning trio did not choose to disembark in the nearest San Francisco, but went to Angel Island in the opposite direction.
Upon learning of this clue, the police immediately went to Angel Island to search, but at this time, a week had passed since the prison escape, and only suspicious items such as raincoat fragments and deflated life jackets were left on the island.
Less than a year after the trio escaped, Alcatraz Prison was closed, and the reason has not been disclosed.
Once a feared prison, it has been transformed into one of San Francisco's hottest tourist attractions;
There are still many tourists who visit the island with curiosity, and movies inspired by the rumors on the island are endless.
Sixty years have passed, and the traces of the three criminals who escaped from prison have always been an unsolved mystery.
Since then, it has been claimed that after meeting the Angel brothers in Rio de Janeiro, there is no follow-up...
