UPDATE: Lowndes County Sheriff Ashley Paulk said preliminary autopsy results Friday afternoon indicate natural causes in the death of William Theodore Reynolds.

VALDOSTA – A Lowndes County Jail inmate died Thursday afternoon, according to the Lowndes County Sheriff’s Office.

William Theodore Reynolds, 63, of Valdosta died Thursday, Lowndes County Sheriff Ashley Paulk said Friday morning.

Reynolds was jailed Wednesday, Jan. 2, on a probation violation, the sheriff said.

“He was in the general population and he said he had chest pains to other inmates,” Paulk said, but he didn’t mention having chest pains to authorities.

He was in a cell block with other inmates when he collapsed; authorities responded by performing cardiopulmonary resuscitation, the sheriff said.

The death appeared to be from natural causes, Paulk said, but the body has been sent for an autopsy to the Georgia Bureau of Investigation Crime Lab.
