Some Ohio State students were convinced that their new house was haunted because of the noises coming from the basement.  After a month of wondering, they decided to investigate, and got an even bigger shock when they found a man living down there.

He wasn't a ghost, but he also wasn't a known resident either!  The man had basically been living in a secret room in the basement of the house for free.

The people that lived in the house searched the basement after hearing alarms dinging, and found a locked door.  When they were able to open it, they found a hidden bedroom with food and everything.

One of the residents actually met the guy living in the room earlier, but thought he was just a guest visiting one of his roommates.

In the end the landlord evicted the unwanted roomie, but it doesn't look like any charges will be filed against him.
