Washington State Patrol is investigating a head-on collision that injured five people early Saturday morning in Yakima County.

Troopers say 18-year-old Tyler Schademan of Zillah was traveling eastbound on Yakima Valley Highway, approaching Konnowac Pass when he crossed the centerline striking another vehicle head-on about 3:30 a.m.

Investigators believe drugs or alcohol may have been a factor in the accident.

The collision injured the other driver, 18-year-old Feliza Gonzalez of Wapato and her female passenger, also from Wapato.  Two men, also riding with Schademan -- both from Zillah -- were also injured.  All five people were transported to Yakima Regional Hospital.
