A hyperextended knee can damage ligaments, cartilage and other stabilizing structures in the knee. Young children have softer bones because they're still growing, so a hyperextended knee can result in a chip of bone being pulled away from the main bone when the ligaments stretch too far.
Al Capone is one of the most famous prisoners of Alcatraz. Capone was on the first trainload of prisoners to the new federal prison located on Alcatraz Island. In 1934, Capone became known as prisoner number 85. In true Capone style, he immediately tried to manipulate the system to get special treatment here.
In his teens, Capone was hired by Torrio and his partner, Frankie Yale, and a bouncer in a saloon-brothel they ran in Brooklyn. It was here that Capone picked up his moniker of Scareface Al, after his left cheek was slashed in an altercation over a girl with a hoodlum named Frank Galluccio.
