3 Marines found dead in car died of carbon monoxide poisoning, North Carolina officials say

Three Marine lance corporals from Camp Lejeune found dead in a vehicle Sunday morning outside a North Carolina store died of carbon monoxide poisoning, officials said Wednesday.

Deputies found the bodies around 9 a.m. Sunday in the parking lot of a Hampstead convenience store, about one hour from the military training facility. The deputies were responding to a missing person report, the Pender County Sheriff's Office said. The office had received a phone call on Sunday morning from a woman who said her son, a Marine, had failed to arrive on a flight to Oklahoma the night before. 

Later that morning, deputies found the body of the missing Marine, along with those of the two other Marines, inside the vehicle.
