A fatal car collision near the Dungeness National Wildlife Refuge on Wednesday afternoon leaves one man dead and another in custody for alleged vehicular homicide.

Det. Josh Ley with Clallam County Sheriff’s Office said Clallam County Fire District 3 and law enforcement arrived on scene shortly after 3:48 p.m. Oct. 18, after a Ford F-350 service truck traveling northbound on Kitchen-Dick Road collided with a Ford Windstar van going west on Lotzgesell Road.

Ley said the truck driver, Vance Mattix, 50, of Joyce, did not negotiate the curve, crossed into the other lane and struck the van driven by 61-year-old Sequim resident Andrew Courney.

Courney sustained critical injuries from the wreck and was pronounced dead upon arrival at Olympic Medical Center, Ley said. The driver of the Ford truck sustained minor injuries and was not transported by medics from the scene, Clallam County Sheriff’s Office said.

Mattix appeared to be impaired from alcohol consumption, Ley said, and was arrested for vehicular homicide.

Two drivers reported Mattix for erratic driving on U.S. Highway 101 east of Sequim about 15-20 minutes before the collision, Ley said.

Mattix was booked into Clallam County Corrections Facility and appeared in Clallam County Superior Court Thursday, Oct. 19, Ley said.

The case will be forwarded to the Clallam County Prosecuting Attorney’s Office for formal charging for the crime of vehicular homicide, the Clallam County Sheriff’s Office said.

The crash remains under investigation by the Clallam County Sheriff’s Office and Det. Ley.
