A Mississippi woman has been sent to jail after her child died in a hot car while she had sex with a police supervisor.

Former Mississippi Gulf Coast police officer Cassie Barker was sentenced on Tuesday to 20 years in prison for the death of her daughter Cheyenne Hyer in 2016, local news reported.

The 29-year-old pleaded guilty to manslaughter after taking a plea deal when she was first charged with second-degree murder.

Three-year-old Cheyenne was strapped into her car seat in a patrol car for four hours while her mother was with her then-supervisor.

The car's air conditioning was on at the time, but was not blowing cold air, local media reports.

Cheyenne was unresponsive when Barker returned to the car, and had a temperature of 42degC.

A GoFundMe page was set up for the child's funeral by her father, Ryan Hyer.
