Washington State Patrol is seeking witnesses to a hit and run after a semi-truck caused a collision on June 19 that injured a Federal Way woman on State Route 18.

At approximately 6:57 p.m., WSP received a report of a collision near the Raging River, milepost 26.

When troopers arrived they found a Nissan Rogue and a Tesla Model S blocking both eastbound and westbound of the highway. They determined an unknown semi-truck had caused the collision but failed to stop, according to WSP.

The semi and the Nissan were traveling westbound on SR 18 and the Tesla was traveling eastbound when the semi struck the Nissan, forcing it into the eastbound lane and causing it to collide with the Tesla. A third vehicle traveling westbound struck the Tesla.

A 70-year-old Federal Way woman who was a passenger in the Tesla, and a 52-year-old Snoqualmie man who was driving the third vehicle involved in the collision, suffered minor injuries. Both were transported to Overlake Hospital.

It is unknown if drugs or alcohol were involved in the collision.

WSP detectives are seeking any witnesses that may have information who will assist in identifying the semi that caused this collision. Contact Detective Ruth Medeiros at 425-401-7788 or email at Ruth.Medeiros@wsp.wa.gov.
