Authorities suspect Jerice Hunter beat and kept her daughter Jhessye Shockley in a bedroom closet at the family's suburban Phoenix home depriving her of food and water until she died.
Hunter has pleaded not guilty to charges of first-degree murder and child abuse.
Prosecutor Blaine Gadow says Hunter stuffed Jhessye's remains in a suitcase and threw her in a trash bin in a neighboring city.
Hunter's lawyers say there's no proof that Jhessye is dead after authorities sifted through a landfill for 96 days and found no remains.
The jury is expected to resume deliberations on Wednesday at 10:30 a.m.
