Fire marshal investigators are digging through a former topless coffee shop in Maine as they try to determine what caused a blaze that gutted the building. Wednesday afternoon investigators told media that the fire was intentional and that the shop and surrounding area is a crime scene. The fire was reported at about 1 a.m. Wednesday at the Grand View Topless Coffee Shop in Vassalboro, just north of Augusta.Owner Donald Crabtree lived in the former motel, and he and six others including his daughters and their babies escaped unharmed. The shop opened to national headlines in February, but it raised the ire of many local residents. The fire happened hours after Crabtree met with planning officials to discuss his proposal to expand the business to make it more like a strip club. Crabtree says he spent $277,000 buying and renovating the building. It wasn’t insured.Investigators from the fire marshal’s office are encouraging anyone with any information to call 1888-870-6162.
