Vehicular manslaughter trial slated for October in Stephens County

DUNCAN — The felony jury trial for a Marlow man accused of being high while killing a man in an April 2022 wreck has been continued.

Austin Wayne Winsor, 25, appeared Wednesday in Stephens County District Court relating to a felony charge of first-degree manslaughter, records indicate. The crime is punishable by up between four years to life in prison.

District Judge Ken Graham continued the case and scheduled it to begin with jury selection at 9 a.m. Oct. 21, records indicate.

Investigators said Winsor was driving southbound on 3-Mile Road shortly after 7 p.m. April 19, 2022, when he failed to stop at the stop sign and struck a Chevrolet Suburban in the passenger side driven by Matthew S. Graham, causing it to overturn 1¾ times. None of the occupants of the vehicles were wearing seatbelts, according to the investigation.

Graham, 42, of Comanche, was pronounced dead at the scene. The passenger, an unidentified then-14-year-old girl from Cache, was flown to Comanche County Memorial Hospital and later transferred to OU Children’s Hospital for treatment of an unspecified internal injury.

Two other passengers in the Suburban also were treated for injuries and released, according to the Oklahoma Highway Patrol.

Winsor was flown to Duncan Regional Hospital where he was treated and released with a head injury. According to the warrant affidavit, the presence of THC from marijuana and methamphetamine was found in his system.

Winsor has been held on $250,000 bond since his initial court appearance on Nov. 1, 2022, records indicate.
