LEAVENWORTH — The Chelan County sheriff says a 17-year-old Leavenworth boy was fatally injured in a weekend accident while riding an all-terrain vehicle.
Sheriff Brian Burnett said Monday that Mark D. Clark was riding the ATV on Sunitsch Canyon Road in Leavenworth when he apparently lost control and was thrown against a tree, with the ATV rolling into him, causing neck and head injuries.
Medics pronounced the teen dead at the scene on Saturday.
The sheriff says the boy was not wearing a helmet
