A Fox man, who has already served time for two manslaughter convictions he earned as the result of a driving-under-the-influence case in 1999, will exercise his rights to a preliminary hearing in connection with a third manslaughter charge filed against him in the July 17 run-over death of a Ratliff City woman.

First Assistant District Attorney Heather Cooper said prosecutors were advised Tuesday Charles Jackson would seek a preliminary hearing in connection with the death of Carol Coker. The victim was walking on the shoulder of state Highway 76 and died of injuries she sustained when Jackson, who was driving northbound on the highway, veered off the road and struck her.

Cooper filed the first-degree manslaughter charge against Jackson. In addition, Cooper is seeking after-former-conviction penalty enhancement in the case as the result of his previous convictions. Jackson was charged with two counts of first-degree manslaughter in the DUI deaths of two Oklahoma County residents. He was convicted in that case in 2000 and sentenced to a state prison. The 56-year-old man was paroled in 2004.

The Carter County District Court charge is the result of an extensive investigation conducted by the Oklahoma Highway Patrol that produced evidence Jackson was driving under the influence of prescription drugs when he drove his car into Coker.

“He attempted to flee the scene, but was stopped by eye witnesses. A short time later, an OHP trooper and Carter County Sheriff’s deputies arrived. During the investigation, it was determined that Jackson was operating under the influence of prescription medication and impaired,” said Capt. Ronnie Hampton, commander OHP Troop F. “We appreciate the Coker family’s patience as we investigated this tragic death. Cases involving drug-impaired drivers require extensive investigative work.”

The charge was filed against Jackson in March and a warrant was issued for his arrest. He was taken into custody March 26 by Carter County deputies and booked into the Carter County Detention Center. A $50,000 bond was set on the arrest warrant. Jackson posted the bond even before making his initial appearance in district court. He currently remains free on the warrant bond. His preliminary hearing is set for 9 .am. June 24.
