43-year-old Sharon Scott of Meridian was found dead inside a holding cell at the Meridian Police Department at 4:00 a.m. Tuesday.
"We do checks of the cells every 30 minutes and one of the officers discovered her at 4 a.m. this morning," said Chief Benny Dubose.
"Immediately the officer called for assistance and along with the officer, two other officers attempted CPR."
However, officials say they believe Scott was dead. Investigators say she was found hanged from a bed sheet.
Following her arrest a few hours earlier, officers say Scott was placed in the cell alone. Chief Dubose says Scott was charged with a number of traffic violations.
"One of her charges was DUI refusal, which required a mandatory holding period of five hours," Dubose said.
Dubose says foul play is not suspected, but procedure is for an outside agency to investigate. In this case, it's the Mississippi Highway Patrol.
"Any time there's anything in our department that can possibly raise some questions, we call in an outside agency to investigate that. That way we'll get an objective 'hands-off' investigation," said Chief Dubose.
Autopsy results are expected within a couple of days. Officers say it could be at least a week before the highway patrol wraps up its investigation.
