Sheila Sillery-Walsh, visiting San Francisco from Birmingham England, managed to capture a curious imagine on her iPhone “whilst” on a tour of Alcatraz. According to the UK’s Daily Mail, Sillery-Walsh explains, “‘Whilst doing an audio-tour of the place, I casually stopped to take a snap of the empty visitation block window on my iPhone. When I glanced at the photo on my mobile, I saw this dark female figure in the picture. I looked at the window again and there was no-one in the room. I knew straight away that the woman in the photo was a ghost and showed the snap to Paul.”

Paul Rice is Sillery-Walsh’s partner and is completely on-board with the ghost theory, or so he told the Daily Mail. “I have no logical explanation for the girl in the picture – I’m baffled by her! It’s funny because she’s staring right at the camera, with a knowing look. I was really skeptical about ghosts before but I’m a bit more of a believer now. I do think that the woman in the photo is a ghost.”

If a ghost was haunting Alcatraz, wouldn’t it be a prisoner, doomed to wander the grounds forever paying his debt to society? Alcatraz is no stranger to ghost stories and spooky sightings. Officially, however, Alcatraz is not haunted.

What do you think? Do you believe in ghosts? And what exactly did Sillery-Walsh photograph?
