Tyler J. Warne, 18, was killed in a one-car crash on Interstate 255, Illinois State Police Sgt. Bill Moseley said. Warne's last known address was at his parent's house in Manchester, Mo.

The crash was about 3 p.m. Friday on northbound I-255, just before the Collinsville Road exit. The 2008 Mazda car drove off the east side of the road and down a small embankment, Moseley said. The car rolled several times, landing on its roof, and ejected the driver and passenger.

Warne was pronounced dead at the scene by St. Clair County Coroner's officials.

The passenger, a 17-year-old Ballwin, Mo., man, was flown to Cardinal Glennon Children's Hospital in St. Louis.

At the time the passenger was taken to the hospital, he had serious, but non-life threatening injuries, Moseley said.
