A Kennewick man fled on foot Saturday after being involved in a three-car collision near where Highway 240 becomes Stevens Drive.
Jesse A. Fox, 33, was driving westbound on the highway in a Nissan Altima just after 1 p.m., a release from Washington State Patrol said.
Sally Huber, 53, of Richland, and passenger Karen Hutchkinson, 57, were in a Toyota Rav4, and Robert Meyers, 50, of Richland, and Joyce Henry, 56, of Umatilla, were in a Subaru Legacy.
The Toyota and Subaru were stopped at the stoplight for Stevens Drive and Highway 240 when Fox's car left the roadway and struck them. He left the scene, and his whereabouts were not available.

All vehicles were totaled. Hutchkinson, Huber and Henry were taken to Kadlec Regional Medical Center in Richland. Their conditions were not available Sunday. Meyers was uninjured.
Authorities are still investigating the crash, and charges are pending.
