WSP Seeks Witnesses To Deadly SR 18 Crash

ISSAQUAH, WA - A deadly crash that shut down SR 18 near Tiger Mountain Wednesday night was likely caused by a piece of debris in the road, according to Washington State Patrol. Kyung Cho, a 57-year-old Federal Way woman, died in the crash, and a 55-year-old Covington woman was injured.

The crash happened just before 5 p.m. Wednesday near where SR 18 crosses the Raging River, which is between I-90 and Tiger Mountain State Park. According to state patrol, Cho was traveling eastbound when her car hit a piece of debris in the road. That caused Cho to lose control and cross into the westbound lanes. Her car collided head-on with a Jeep driven by Brenda Hoyt of Covington.

The crash blocked all east and westbound lanes of SR 18. The road was not completely reopened until around 9 p.m. Wednesday.

On Thursday afternoon, state patrol put out an advisory asking anyone who was in the area and might've witnessed something to contact Det. Brody Ford at (425) 401-7742 or via email brody.ford@wsp.wa.gov.

Police believe the debris in the road was a piece of a semi truck's driveline. Police believe the driveline might've fallen off a semi hauling other semis behind it.
