Alcatraz located in San Francisco, CA is also believed to be haunted. Alcatraz is known to be one of the roughest federal penitentiaries in the nation. The history of Alcatraz began in 1850, where military prisoners were sent there to build the prison where they would be imprisoned. The first haunting was reported in the 1940s, where a prisoner was found screaming at night claiming that something in his cell was trying to kill him. He was then found strangled to death. Today, staff members and many visitors of Alcatraz still report seeing and hearing spirits. This creepy image above shows a ghostly girl lurking in one of the prison cells at the notorious Alcatraz Federal Penitentiary.
