Officials are investigating two accidents over the weekend that killed two people and injured three others.

The Oxford County Sheriff's Office says the car accident happened around 1:00 Sunday morning in Buckfield, at the intersections of Route 117, North Whitman School Road, and South Whitman School Road. Two vehicles collided, with a passenger in a sedan dying at the scene. WABI-TV reports the driver of that vehicle had to be airlifted to a Lewiston hospital, while another was taken to the hospital by ambulance, along with the driver of the second vehicle.

In Sebago, a man died while riding a dirt bike on Sunday. Corporal John MacDonald says it appears he lost control of the bike and struck an embankment, while traveling off-road.

The names of those involved in both accidents have not been released, pending notification of family. Officials continue to investigate the crashes.
