MARIETTA, Ga. (AP) — A Georgia man accused of intentionally leaving his toddler in a hot vehicle to die has pleaded not guilty to the charges against him.

Staci Brinson, the staff attorney for Cobb County Superior Court Judge Mary Staley, said a lawyer for Justin Ross Harris on Friday waived formal arraignment for his client and entered a plea of not guilty.

Harris has been in custody since he was arrested in June. He was indicted last month multiple charges, including malice murder, felony murder and cruelty to children.

Police have said Harris left 22-month-old Cooper in an SUV for about seven hours on a day when temperatures reached at least into the high 80s in the Atlanta area.

Harris' attorneys have said the child's death was a tragic accident.
