Two fatality collisions, one in Seabeck and the second in Kingston, occurred last week.

A 39-year-old woman died in a car crash Nov. 10 while driving alone on the Seabeck Highway. No one else was injured. In a separate incident Nov. 11, a 23-year-old Bremerton man died while driving on Cliffside Road in Kingston. A 23-year-old passenger was airlifted to Harborview Medical Center in Seattle.

The Nov. 11 incident was reported at 11:44 a.m. and occurred in the 2500 block of Seabeck Highway. The woman was declared dead at the scene. She was driving in her 2001 Volvo south on Seabeck Highway at a “high rate of speed,” according to sheriff’s reports.

The woman failed to negotiate a curve to the left and her car struck a guardrail and launched over the embankment. The Volvo rolled and struck a tree, impacting the car’s roof, before crashing on the ground.

The woman was from Del Mar, Calif. The highway was closed to traffic until about 4 p.m.

The Kingston crash was reported at 12:08 a.m. and the driver was declared dead at the scene. The Bremerton man was driving a 2004 BMW east on Cliffside Drive “at a high rate of speed” and veered off the road onto the south shoulder and struck a traffic sign after passing through the intersection with Little Boston Road.

The car’s momentum carred it over the embankment and down a ravine where it struck several trees and rolled. The car ended stopped on the driver’s side in heavy brush.

The passenger, of Poulsbo, sustained serious head injuries and multiple fractures. He was listed as being in stable condition.

Excessive speed is suspected to be a primary factor in the cause of the crash. Investigators believe that alcohol consumption maybe be a factor in the cause of the crash, but are waiting toxicology results as part of the autopsy.
