A 19-year-old man was killed in an early morning car accident in the 2500 block of Ousdahl Road. Police withheld the name of the victim, but the family confirmed it was Casey Alan Anzek of Lawrence.

Four other passengers, all from Lawrence, were injured.

Two girls, ages 16 and 17, suffered life-threatening injuries and were transported by air ambulance to Kansas University Hospital.

Two other passengers, a 20-year-old man and a 16-year-old girl, suffered less severe injuries and were taken to Lawrence Memorial Hospital, said Lawrence-Douglas County Fire & Medical Battalion Chief Joe Hoelscher.

The single-vehicle accident occurred at about 2:10 a.m. Saturday at the intersection of 25th Terrace and Ousdahl Road, a residential area. The car, a 1984 Chevrolet, was heading southbound on Oushdahl Road when it went off the east side of the road and slammed into a tree in front of a home.

The driver was pronounced dead at the scene.

Lawrence Police Sgt. Susan Hadl said a passer-by extricated the injured passengers.

Police are investigating the cause of the accident.

Hadl said speed, alcohol and a wet roadway could be to blame but said the investigation would continue.
