A 2003 Chrysler Town and Country minivan was also traveling westbound and swerved into the eastbound lane to avoid hitting the first vehicle. At that point, it collided head-on with a 1997 Buick LeSabre sedan traveling eastbound.

Neither the driver of the unidentified white vehicle nor the car itself was identified, and Hilligoss said other law enforcement agencies have been asked to look for the vehicle.

“All I know is the car that pulled out is the one that caused it,” Dorothy Neis said.
