HINESVILLE — A Georgia foster mom has been charged with second-degree murder after 3-year-old twins were found dead in a hot car.

News outlets report Claudette Foster was charged after Payton and Raelynn Keyes went missing on Sunday, Sept. 29, and were found dead hours later in the car in Hinesville.

At approximately 1:42 p.m., a 911 call was received indicating two children had been missing and were found unresponsive in a vehicle located in the back yard of a home on Augusta Way in the Griffin Park neighborhood.

First responders arrived on scene shortly afterward and found the two unresponsive toddlers inside the parked vehicle.

 The first responders determined that the two 3-year-old children were deceased, and authorities immediately began a death investigation. A perimeter was established and all individuals present at the home were removed at the time.

Autopsies determined the children died from accidental heatstroke.

Georgia law allows charging caregivers with second-degree murder when children die because of cruelty stemming from criminal negligence. Foster is also charged with second-degree child cruelty.

Hinesville police Detective Bryan Wolfe told WSAV-TV that Foster's "lack of supervision for the children ... allowed them to enter the vehicle and pass away."

 Foster has been jailed without bond in Liberty County. It was not immediately known if she has an attorney.
