Harris told authorities that his son, Cooper, was left accidentally in a carseat in the backseat of a four-door SUV during a day when temperatures reached the low 90s.
Cooper remained in the vehicle until he was discovered by a distraught Harris at a Cumberland-area strip mall parking lot. By then the unresponsive toddler had died.
WSB reported Tuesday that a source close to the investigation said there’s evidence that the Marietta father did have contact with the vehicle during the seven-hour window when Harris said he was at work at the Home Depot headquarters and the boy was in the vehicle.
The medial examiner’s report has yet to be released.
Harris, 33, has been charged with murder and cruelty to children. He remains in the Cobb County jail without bond and is expected to be there this weekend when his son is buried.
The Tuscaloosa, Ala., native’s next court appearance is set for July 15.
