More than 30 firefighters doused flames that all but consumed a vacant home Saturday at 2 Solomon St., Hanover Township. A state police fire marshal is investigating the fire, which is considered suspicious because the house was vacant and condemned. Hanover Fire Chief Jeff Tudgay said there was electricity servicing the house that was vacated at the end of July. The structure will be leveled, he said. Buildings on both sides of the fire sustained damage. Donald Witkowski, who lives at 3 Solomon St., said he was preparing lunch around 10 a.m. and lifted the kitchen curtain. “That’s when I saw the fire shooting out of the porch roof,” he said. Witkowski was provided emergency housing by the American Red Cross.
