HOMESTEAD, Pa. -- The Homestead Police Department hired paranormal investigators to look into hauntings at its station. The hauntings have been a rumor for years. Now, Homestead police officers want proof that they're for real.

Slamming doors and creaky floors are one thing, but police officers say some of the other incidents cannot be explained.

First, there’s the phantom typist. Several people have seen the keys on a typewriter moving on their own. Others can't explain the attic door, which continues to spring open no matter how many times it’s bolted. The chilling air that blows through enclosed hallways and around old cellblocks is also pretty spooky, the officers said.

Denise Kelly, who worked at the building for years, showed Channel 11’s Renee Kaminski a room she and other staffers almost never entered alone. That's where local paranormal investigators set up shop when they visited.

The mysterious incidents haven't just happened inside the borough building. The mayor showed Renee Kaminski a broken down snow plow that somehow started up last November without a key and battery.

The department called on the Greater Pittsburgh Paranormal Society, and they said they found something in the boiler room. Paranormal investigators said the staff will have to wait until their investigation is complete to find out what they believe is that something.
