Authorities have concluded that alcohol played a role in an accident that killed a woman in northern Osage County.

The Oklahoma Highway Patrol says 24-year-old Kiley M. Jones, of Delaware, Okla., died of internal injuries and head trauma on Monday, a day after the crash east of Hulah Lake.

The patrol says 27-year-old Cameron Wawrzynaik was driving a pickup truck on Oklahoma 10 when it veered off the road, went over a ditch and struck a pipeline valve head-on about 3:15 p.m. Sunday.

Jones and Wawrzynaik were flown by medical helicopter to St. Francis Hospital in critical condition. Jones died about 11:30 a.m.

Twenty-two-year-old Caney, Kan., resident Andrew Haughn also was in the truck, but was treated at a Bartlesville hospital and released.

Troopers say Wawrzynaik had been drinking, which likely caused the wreck.

The patrol report says no one in the truck was wearing a seat belt.
