Authorities say alcohol played a role in a weekend traffic fatality that killed a 25-year-old Miami man.

Joshua William Cox died around 11:30 p.m. Saturday, about 7 miles southeast of Fairland, according to an Oklahoma Highway Patrol report.

Troopers say Cox was driving at a high rate of speed when he failed to negotiate a curve in his Chevrolet pickup. The truck ran off the roadway and struck a tree.

He was freed by the Fairland Fire Department and transported by Quapaw Tribal EMS to Miami Baptist Regional Hospital where he was pronounced dead of massive injuries.

Troopers reported an odor of alcohol and noted Cox was not wearing a seat belt.

Friday, a 41-year-old Grove man and his 8-year-old son were injured in a one-vehicle accident just south of Fairland on Highway 125.

Authorities say Rusty Roark was driving southbound on Highway 125 when his 2000 Nissan ran off the roadway, traveled about 25 feet and struck a cement culvert head on.

Roark was transported by Quapaw ambulance to a Joplin, Mo., hospital, where he was treated and released with a leg injury.

His son, Adam Roark was airlifted to a Joplin hospital, where he was admitted in good condition with head and leg injuries.

Troopers say the cause of the accident is unknown.
