MILWAUKEE - Thanks to the blockbuster movie, we're hearing a lot of chatter these days about paranormal activity - or as most of us refer to it - ghosts. From Hollywood to right here in Wisconsin, people are wondering if it's fact or fiction.

So just in time for Halloween, we wanted to do our own 'Paranormal Investigation.' So we tagged along with some Wisconsin ghost-hunters. What we found may even change the minds of skeptics.

It was a cool, foggy night outside the Scottish Rite Masonic Center in downtown Milwaukee. Inside, there seems to be more than just time passing through the hallways. Inside the more than 100-year-old building, the walls are covered with history. Some claim that history is coming alive. That's why Mike Hill, the Masonic Center's executive director, called Wisconsin's version of the Ghostbusters--The Southern Wisconsin Paranormal Research Group.

"A few things have moved around in the office, Poltergeists," Hill admits.

The founders of Milwaukee were Masons, and many of them were Scottish Rite Masons. Now, they may be roaming these hallways once again, and these ghost hunters are right behind them. Troy Hartman is a senior investigator for the S.W.P.R.G.

TODAY'S TMJ4'S Jay Olstad: "Is this something where people call you and say, 'I got something weird going on, I need you?'"

Hartman: "Yes, we get that probably two or three times a week, especially during Halloween time."

They take sophisticated equipment, and test the areas for electromagnetic fields and room temperatures.

"You're finding the natural stuff, and getting it out of the way so later on when we're like, 'What was that spike? Is that a ghost or a microwave going off?'"

Tom Curtis is one of the members of the Scottish Rite. He says he wouldn't be surprised at all if investigators found signs of paranormal activity in the center. Now he spends his days at the Scottish Rite Center, but as a kid he spent them in his old east coast farm house.

Tom recalls, "I went over to the attic doorway, pushed open the attic door, and someone pushed back."

He later found out that the former owner of the farm house had died in the attic!

Troy and his ghost hunters didn't find anything that dramatic at the center, but they did find something.

Investigator Sarah Bina was taking pictures in the very room where employees say ghosts have taken up refuge. She describes what happened to her camera: "It was on and it shut off, and I tried turning it on again and it wouldn't turn on."

Olstad asks, "Brand new batteries?"

Bina: "Brand new, just took them out of the package when we got here."

And that wasn't the only mysterious malfunction.

Hartman points to a tape recorder and says, "That tape recorder just turned on by itself."

That tape recorder, being used to tape voices of the dead, came alive. It wouldn't even shut off when they tried to turn it off! In fact, the switch was turned 'off', and still kept playing.

Hill says he'd like for the investigators to come back. "We need to preserve the building and its antiquities, and if there are spirits in the building we need to preserve them too," he explains.

The ghost hunters plan to come back to the center with a full investigation team and more gadgets to see if those mysterious malfunctions had anything to do with paranormal activity.
