A Georgia man accused of killing his toddler son by leaving him in a vehicle on a hot day is set to appear in court for a hearing.

Cobb County Superior Court Judge Mary Staley is set to hear arguments on pretrial motions Monday in the case of Justin Ross Harris.

Police have said Harris left 22-month-old Cooper in an SUV for about seven hours on a day when temperatures reached at least the high 80s in the Atlanta area. He faces multiple charges, including malice murder, felony murder and cruelty to children.

Harris has been in custody since June 18, 2014, the day his son died. He was indicted in September 2014 and has pleaded not guilty. His attorneys have said the child's death was a tragic accident.
