NEW TOWN, N.D. — Four people are dead after their car collided on the Fort Berthold Indian Reservation with a pickup carrying two military members from the Minot Air Force Base.

The Highway Patrol says all of the victims are from Mandaree. They were in a car that authorities say failed to stop at the intersection of Highways 23 and 8 shortly after 9:30 p.m. Monday and collided with a U.S. Air Force service vehicle.

The driver of the car and three backseat passengers died at the scene about 6 miles east of New Town. A front seat passenger was seriously injured.

Dead are a 23-year-old woman, and men ages 21, 23 and 27. They weren’t immediately identified.

The two men in the pickup weren’t hurt. They are assigned to the 91st Missile Wing.
