Carter County Sheriff Ken Grace said while foul play is not suspected, the OSBI and state Medical Examiner's office is conducting an inquiry into Friday's early morning death of a detention center inmate.

Grace said Jackie Perkins, 26, was found dead in his cell shortly after breakfast trays were delivered to inmates.

"The trays were delivered shortly before 7 a.m. [Perkins] was fine at the time the trays were passed out. A short time later, his cell mate began calling for officers. The cell mate told officers Perkins had been eating, when he just fell over," Grace said.

Perkins was unresponsive and detention center officers immediately called for an ambulance.

"The EMTs arrived and confirmed he was dead. There is no evidence of homicide, but I have turned the investigation over to the OSBI and ME's office to determine the circumstances and cause of death," Grace said.

Ardmore police had booked Perkins into the county jail about 7 p.m. Thursday night pending a domestic assault charge.

"He was arrested after officers responded to a report of a domestic [disturbance], and found Mr. Perkins had been in a physical fight with his mother's boyfriend," said Sgt. Ryan Hunnicutt, APD public information officer. "At the time he was arrested, he had no marks indicating injury and showed no signs of injury. He was arrested without incident."
