Excerpt: I asked them to come to my apartment because, No. 1, they have a TV show, "Paranormal Cops," which has been a modest hit on A&E this winter and will have its season finale Tuesday beginning at 9 p.m., and, No. 2, I wanted to meet on neutral ground, outside of their typically haunted locations. So far, for the show, they have investigated phenomena at the Frankfort Fire Department, the basement of a supposed mob lair in Melrose Park and the former site of Barat College in Lake Forest. (Check out their three favorite haunted spots in Chicagoland.) My apartment would serve as a control -- a place they could demonstrate investigating techniques and thermal-imaging guns without interruption from the unexplained.
