MONROE, MI–Midwest Heating & Air Conditioning secretary Liz Boorstein said Monday she is "almost positive" that the United Vending Services worker who comes by once a month to refill the break-room snack machine is the serial rapist reported on the loose in the area. "Don't you go in there alone if he's in there," Boorstein, 40, warned co-worker Jen Rall. "He looks just like the guy in the police sketch they had on the news. And once, he gave me this really weird look when he was putting in the Kit-Kats." In May, Boorstein was "100 percent sure" that a small hole in one of the ladies' room stalls was the work of a "Midwest Heating & Air-Conditioning peeping tom."
