UPDATE | Ga. dad in hot-car death charged with murder

ATLANTA (AP) — More than two months after his son's death in a hot car, a Georgia man who prosecutors say sat in his office exchanging nude photos with women while his son languished for hours was charged with murder today.

A Cobb County grand jury indicted Justin Ross Harris on multiple charges, including malice murder, felony murder and cruelty to children. The malice murder charge indicates that prosecutors intend to prove Harris intentionally left his son Cooper in the hot car to die, and it opens the door for the district attorney to seek the death penalty.

The eight-count indictment also includes charges related to sexually explicit exchanges prosecutors say Harris had with an underage girl.

Harris has been in jail since his arrest the day his 22-month-old son died. Harris' lawyer, Maddox Kilgore, did not immediately respond to a phone message and email seeking comment.

Harris has told police he was supposed to drive his son to day care the morning of June 18 but drove to work without realizing that the child was strapped into a car seat in the back.

Police have said the toddler was left in the vehicle for about seven hours on a day when temperatures in the Atlanta area reached at least into the high 80s. The medical examiner's office has said the boy died of hyperthermia — essentially overheating — and has called his death a homicide.

In June, police had charged Harris with felony murder and second-degree child cruelty — charges that imply negligence but not intent. The new charges supersede those.
