An elderly man and woman sustained minor injuries in a one-alarm fire in Bourne Monday, Deputy Fire Chief Dave Cody said. The blaze at 9 Portside Drive was reported at 4:49 p.m., Cody said, and ambulances transported both unidentified residents to Falmouth Hospital for smoke inhalation and possible minor burns. The fire appeared to have started near the home’s living room fireplace and was contained in that room, though there was extensive smoke damage throughout the ranch-style house, Cody said. The fire appeared to be accidental, but the state fire marshal’s office is investigating.Jeremy C. Fox can be reached at email@example.com. Follow him on Twitter @jeremycfox.
