PORT ORCHARD — The Washington State Patrol is searching for the driver of a blue pickup truck involved in a serious hit-and-run collision on State Route 16 near Port Orchard Tuesday afternoon.

Two people were reported to have suffered serious injuries when their black Chevrolet Camaro was struck from behind by the pickup truck as they traveled eastbound just west of the Tremont Street exit. Trooper Chelsea Hodgson said the truck was believed to be a late ’90s Ford Ranger.

After being struck, officials said the Camaro left the roadway to the right and struck a tree. The truck was last seen continuing eastbound after the collision at just before 2 p.m., Hodgson said.

The injured driver and passenger of the Camaro were taken to St. Joseph’s Medical Center in Tacoma.

Traffic on eastbound SR 16 was halted for a time following the accident, which created a huge backup nearing the commute time.

WSP is asking anyone with information about the collision to contact Detective Krista Hedstrom by email at krista.hedstrom@wsp.wa.gov or by calling the agency’s non-emergency line at 360-473-0300 and selecting “Option 1” for a dispatcher.
