OXFORD – A 7-year-old boy died in an early-morning fire Tuesday at a mobile home in the Oxford Pines Trailer Park.

Shawn Bennett, a second-grader at Oxford Elementary School, died from smoke inhalation after being rescued through his bedroom window by Patrolman Alan Coffin, one of the first on the scene.

His 11-month-old sister, Andrea Bennett, who was also rescued from her crib by neighbor Raymond Reece, is being treated at Maine Medical Center in Portland and her injuries are not considered life-threatening.

The fire was discovered at 1:49 a.m. at the late-1990s mobile home on Cheryl Lane when the children’s parents, Kathy Bennett, 37, and her husband, Neil Gephart, 30, awoke to find the home filling with smoke, Sgt. Kenneth Grimes of the State Fire Marshal’s office said.

Although an exact cause has not been determined, the fire does not appear to be suspicious in origin, he said.

The fire began in the living room, which is between the parents’ and the children’s bedrooms, he said. The parents were unable to get to the children from within the home, so they escaped through their bedroom window and then tried unsuccessfully to get back in through their children’s windows on the other end of the single-wide home, Grimes said.

Both parents and Coffin were treated for smoke inhalation and lacerations at Stephens Memorial Hospital in Norway. Reece, who reached through a window and pulled the child’s crib close enough to grab the child, was unharmed.

Neighbor Wayne Hatch performed cardiopulmonary resuscitation on Shawn Bennett before the ambulance arrived, Grimes said. The boy was pronounced dead at Stephens Memorial Hospital in Norway.

Maurice Kautz, principal at Oxford Elementary School, said a crisis response team will be in place when students return to classes today. There were no classes Tuesday because of parent-teacher conferences.

The home had two smoke alarms, said Grimes, but he wasn’t sure if that was what woke the parents. “They just remembered they woke up and the home was full of smoke,” he said.

Grimes said firefighters from Oxford, Norway and Mechanic Falls responded to the fire, along with Oxford Rescue and PACE Ambulance Service.

The home was insured, Grimes said. He said investigators will need another day to try to pinpoint the cause of the fire, and further interviews are scheduled.
