Peter E. Kern, who was facing criminal charges after the car he was driving crashed into a building on Island Crest Way last November, has died. Kern, died early Saturday, April 5, at an apartment at 788 110th Avenue N.E. in Bellevue. The King County Medical Examiner’s office said that Kern died of self-inflicted stab wounds and have ruled the death a suicide.

Trooper Chris Webb, Public Information Officer for the Washington State Patrol told the Reporter that on Nov. 8, 2013, a WSP trooper clocked Kern traveling eastbound in the I-90 express lanes at 150 mph in a luxury 2013 Porsche Panamera.

The trooper observed Kern exiting onto Island Crest Way. At the S.E. 30th Street intersection, the Porsche struck a street sign and became airborne before hitting the Mercer Park Dentistry building owned by Islander, Clyde Curfew. The car caught fire after impact. Damage to the building was estimated at $10,000

Kern, 47 at the time of the accident, was arrested at the scene. Kern’s passenger, a woman, was later admitted to the hospital for her injuries.

The King County Prosecutors office said that Kern had been drinking prior to the crash.

Just days before his death, the King County Prosecutors office had filed one count of vehicular assault against Kern. Other charges according to Dan Donohoe of the prosecutors office, were still pending.
