Ardmore Police Chief Ken Grace has asked the OSBI to investigate the circumstances surrounding the death of a 38-year-old local man who was found unresponsive in the back of a police car following his arrest Friday night.

Rondre Hornbeak was taken into custody about 7 p.m. when officers responded to a disturbance in the 1100 block of Holiday Drive.

“A physical altercation had occurred,” said Capt. Kevin Norris, APD Criminal Investigation Division

Hornbeak was taken into custody without incident. At the time of his arrest he was reportedly alert and walked unaided to the police car.

“He was transported to the Carter County Detention Center and upon arrival at the county jail he was found to be unresponsive,” Norris explained adding, “Jail staff immediately began CPR.”

Southern Oklahoma Ambulance Service and Ardmore Fire Department responded to a medical call for assistance and Hornbeak was taken by ambulance to Mercy Hospital Ardmore Emergency Department. He was pronounced deceased at 8:21 p.m. by emergency room doctors.

Hornbeak’s body was sent to the state medical examiner’s office for autopsy and a cause of death determination.

Norris confirmed Grace had requested the OSBI conduct the inquiry into the events to avoid any concern of bias by APD. The two officers involved in the arrest were not immediately identified. The captain said neither officer had been placed on leave.

“At this point we are referring all questions concerning the investigation to the OSBI,” Norris said Saturday.
