What evidence the jury will be allowed to hear in the trial of a Georgia man accused of intentionally leaving his toddler son in a hot vehicle to die is certain to be a central issue in a hearing set to begin Monday.

Justin Ross Harris faces charges in the June 2014 death of his 22-month-old son, Cooper.

Cobb County Superior Court Judge Mary Staley is set to hear pretrial motions at the hearing, which is expected to last several days.

Police have said Harris left the boy in an SUV for about seven hours on a hot summer day. He was indicted on multiple charges, including malice murder, felony murder and cruelty to children.

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