(Scroll down for video) Two police officers were placed on leave after a 3-year-old girl died in a patrol car.

Police officer Cassie Barker of Kiln, Mississippi, left her 3-year-old daughter Cheyenne Hyer, in her patrol car while she went to visit her supervisor Clark Ladner.

The two spent four hours together while the girl was dying in the car.

Hyer was pronounced dead at around 3:30 p.m., after she was left unattended in the vehicle. Police said that the car was left running with the air conditioner on for up to four hours.

Investigators said that they are “fairly certain” that the little girl died from the heat, but they are waiting for an autopsy and toxicology results.
