A traffic stop has led to a death investigation after police in Georgia pulled over a speeding driver and found a dead infant in the backseat of the car.

The Associated Press reports that Greenville police stopped Cameron Ramon Reese, 22, for speeding on Wednesday morning. After police pulled him over, Reese reportedly ran from the car. Officers who looked into the vehicle then found the body of a 1o-month-old baby, Ayla Reese.

Police constructed a timeline of the events prior to the discovery of the dead infant, and told the Associated Press that Cameron Reese had been watching the baby at home when it stopped breathing. He then reportedly contacted the baby’s mother, Nikia Reese, who came to home, and the three of them then left in a car.

The baby’s mother reportedly noticed the baby had a mark under her eye, and when she questioned Cameron Reese about it, he allegedly threatened her with a steak knife. She then jumped from the car.

The baby’s cause of death has not yet been determined, pending an autopsy.

After the suspect fled the car, police reportedly apprehended him with the help of a K-9 unit.

According to KSWO, Reese charged with aggravated assault and concealing the death of another. The terms of his custody are not yet known.
