A speeding car rolled over on a wet south-central Minnesota highway late at night, killing one of the four teens in the vehicle, authorities said Sunday.

The crash occurred shortly after 10 p.m. Saturday on Hwy. 60 near Madelia, according to the State Patrol.

Killed was Ross I. Blomgren, 16, from Butterfield, Minn. Blomgren was not wearing a seat belt and was thrown from the vehicle, the patrol said.

Taken to hospitals with noncritical injuries were the 17-year-old boy behind the wheel, whose identity was being withheld by the patrol, and Julia D. Hiebert, 16, and Rose Martinez, 17. All are from Butterfield, about 25 miles from the crash scene.

The driver and Hiebert had on their seat belts; Martinez did not and was sent to Hennepin County Medical Center in Minneapolis, a hospitalization that suggests she was more seriously hurt than the others.

The car was traveling "at a high rate of speed" on westbound Hwy. 60, when it went into the center median and rolled numerous times, the patrol said. The boy who died and one other person were thrown from the car, which came rest on its roof.
