Pinellas County sheriff's detectives are investigating the death of inmate at the county jail's North Division that occurred early Sunday, authorities said.
However, the death does not appear to be suspicious, officials added.
Timothy Matthews, 58, and an inmate serving a one-year sentence for possession of drug paraphernalia, collapsed and died in the county jail's housing area, the Pinellas County Sheriff's Office said.
Matthews complained of chest pains before he collapsed, a sheriff's office news release states.
Detention and medical staff members performed cardiopulmonary resuscitation, or CPR, on Matthews until paramedics arrived on scene. Matthews was pronounced dead at about 2 a.m. Sunday.
According to detectives, there were no obvious signs of injuries and no incidents of confrontation or use of force.
The inmate's next-of-kin was notified.
Matthews was sentenced in September to spend 364 days in jail after pleading guilty to possession of drug paraphernalia.
The Pinellas County Medical Examiner's Office will conduct an autopsy to determine the cause and manner of death.
The investigation continues.
