A Washtucna teenager, who was injured earlier this month in a collision nine miles south of Ritzville, died Friday, according to the Washington State Patrol.

Jeffery S. Zupan, 18, of Washtucna, was driving too fast for conditions, while northbound on state Route 261, in a white 2006 Buick LaCrosse just before 1:49 p.m. Dec. 22, the WSP reported.

Zupan failed to negotiate a curve because of his speed, the WSP said, and the vehicle crossed the center line and struck a gray 2008 Toyota Tundra driven by Kurtis W. Klein, 19, of Edwall.

Zupan was flown to Providence Sacred Heart Medical Center in Spokane for his injuries, but died Friday.

He was not wearing a seat belt and investigations determined drugs or alcohol were not a factor. However, the WSP deemed the cause of the collision as speed. Zupan’s vehicle was totaled.

Klein was uninjured and wore a seat belt. His truck had reportable damage.
