READ: Research Team Experiences Paranormal Activity on Alcatraz Island

Now notorious for being one of the most haunted prisons in America, the ghosts of Alcatraz are still alive and well— metaphorically speaking, of course. Recently, a team of researchers experienced the prison’s paranormal activity firsthand when they stayed overnight while working on a project to create a 3D map of Alcatraz Island.
