Witnesses Needed For A Serious Injury Collision On I-5

September 5, 2023

King County: At approximately 5:00am yesterday, September 4, 2023, a Washington State Patrol (WSP) Trooper drove up on a serious injury collision SB I-5 just south of Mercer St.

When the trooper arrived he observed two passenger cars with heavy front end damage and one semi with minor damage. The location of the vehicles and debris across all lanes made it necessary to shut down all lanes of SB I-5. Seattle Fire Department responded as there were multiple occupants with injuries and one trapped in a vehicle. Multiple patients were transported to Harborview with injuries ranging from a broken leg to internal injuries.

The driver of the causing vehicle was transported to Harborview and was showing signs of impairment and placed into custody for investigation of Vehicular Assault. Detectives are seeking witnesses to the collision or the causing vehicles driving prior to the collision.

Please email Detective Haake at Russ.Haake@wsp.wa.gov.
