ROGERS COUNTY, Oklahoma - Oklahoma Highway Patrol has released additional information about a wreck that killed a Jenks man Saturday night on the Will Rogers Turnpike. Curtis Lee Cockrell, 55, was standing outside his truck when he was killed around 11 p.m.

The investigation into the three-vehicle collision shows Cockrell ran into a snow plow that was applying salt to the inside lane of the highway with its emergency lights activated. Cockrell's pickup hit the plow from behind, and he got out of the truck.

That's when he was hit by another pickup driven by Jonathon Brady, 31, of Tulsa. Neither Brady or the snow plow driver, 56-year-old Charles Summers of Ketchum, were injured enough to require medical treatment, the collision report states.

The cause of the collision is listed as unsafe speed for ice or snow on roadway.
