LOUISVILLE, Ky. (WDRB) -- Two people are dead and several others hurt after a single-vehicle crash in Grayson County.

Grayson County Sheriff's Department Road Deputy Dylan Bohn said the crash happened Saturday around 2:30 p.m. central time on the Western Kentucky Parkway, near the 93 mile marker.

The vehicle was traveling east when it left the roadway for an unknown reason and entered the median. The driver, 43-year-old Charles Martin, over-corrected and crossed both eastbound lanes before hitting an embankment. 

Police said the vehicle rolled at least twice before stopping across the eastbound lanes of the roadway.

42-year-old Melanie Wiles, who was sitting in the backseat, was ejected from the vehicle when it hit the embankment and was pronounced dead at the hospital. 

Martin was pronounced dead at the scene.

Two other passengers were airlifted to U of L Hospital with life-threatening injuries, and two additional passengers were taken to Twin Lakes Regional Medical Center to be treated for minor injuries, police said.

Drugs or alcohol do not appear to have been factors in the crash, but police said initial interviews with those involved suggest no one was wearing a seat belt.
