The Port Orchard man believed to have caused a fatal car crash in 2022 is facing vehicular homicide charges after blood tests allegedly determined he was operating under the influence of drugs.

Chadwick Rosenberg, 46, was identified as the driver of a 2022 Chevy Silverado that was involved in a head-on car collision in the 200 block of SW Bay Street. Port Orchard police allege Rosenberg was eastbound before drifting into the westbound lane.

Rosenberg collided with a 2022 Toyota Tacoma truck driven by 70-year-old Kathleen Terra. Both were transported to St. Joseph Medical Center in Tacoma.

Terra was in critical condition and then died June 20.

Rosenberg consented to a voluntary blood draw while at the hospital. The results conducted in the State Patrol Crime Lab allege positive results for amphetamine and methamphetamine. The results differ from statements collected by police while interviewing Rosenberg.

An analysis of the electronic data recorder from this vehicle alleges Rosenberg was traveling 43 miles an hour in a posted 35 less than half a second before the collision.

Rosenberg was arrested by Port Orchard police and booked into the Kitsap County Jail June 18. An arraignment scheduled for June 20 was delayed.
