A former Mississippi police officer has turned herself in to face a manslaughter charge after her child died Friday when left in her patrol car.

Hancock County Chief Deputy Don Bass said Thursday that Cassie Barker surrendered to authorities Thursday afternoon. Officials had issued a warrant for her arrest earlier in the day.

It's unclear whether she will be released or held in jail. Attorney Donald Rafferty of Gulfport declined comment to reporters as he and Barker entered the sheriff's office in Bay St. Louis, according to video posted online by WLOX-TV.

Officials quote Barker as saying she fell asleep while visiting another officer, as her 3-year-old daughter sat in a running patrol car. The child was found unresponsive and pronounced dead at a hospital. The Long Beach Board of Aldermen on Tuesday fired Barker and the other officer, Sgt. Clark Ladner.

Officials don't now plan to charge Ladner.
