SyFy channel's paranormal investigation show "Ghost Hunters" aired an episode on Wednesday, September 5, featuring a visit to Charleston's Old City Jail.

The investigation, which team leader Jason Hawes described as "one of the most interesting to date," turned up some pretty compelling evidence pointing toward paranormal activity inside of the Old City Jail.

The crew heard bangs, footsteps, whistling, shouting and even saw a moving black mass - but the real icing on the cake was when a crew member repeatedly found scratch marks all over her body.

Are there malevolent spirits still haunting the Old City Jail? You can be the judge - watch the episode below.
