Autopsy results indicate that the death of 69-year-old Robert Sharp, who died after being in the Wood County Jail, was a suicide.

The Wood County Sheriff’s Department issued a press release stating that the results of their internal investigation, the Texas Rangers’ investigation and the autopsy have been received by the sheriff.

“All indicate that inmate Robert Sharp died at ETMC Hospital in Tyler on August 4, 2016 at 10:15 p.m. as a result of injuries sustained in an attempted suicide on Friday, August 4, 2016 while being detained in the Wood County Jail,” the release states.

Sharp, who had been detained since July 25 on a charge of assault family violence, was being housed in a separation medical cell and was being checked every 30 minutes by the detention officer on floor duty. After the floor officer made her check at 3:23 p.m., the release states, Sharp attempted to take his life by hanging himself in the shower utilizing material torn from his jail uniform.

He was discovered unresponsive approximately 23 minutes later by the detention officers. CPR was administered and Sharp was transported to East Texas Medical Center Quitman emergency room and subsequently flown to ETMC Tyler where he later died. Smith County Justice of the Peace Mitch Shamburger pronounced him dead.

“There was never any indication that Inmate Sharp was suicidal or intended to harm himself,” Sheriff Jim Brown said.
