A lightning strike early Saturday morning in Dennis caused heavy damage to a 2½-story home and displaced four adults—the owner, his wife, and their adult son and daughter-in-law, according to the Dennis Fire Department. Firefighters received multiple calls — from a neighbor, a woman driving by, and the occupants of the house — shortly before 7 a.m., reporting that lightning had struck the house on Donovan Way, said Assistant Fire Chief John Donlan. Lightning hit the back corner of the roof, igniting the roof and top floor, according to a statement from the Dennis Fire Department. The lower two floors of the home, where the occupants were sleeping, sustained smoke and water damage. The storm woke up the occupants of the house, who were able to get out with no injuries.
