(Atlanta, GA) -- Another suspect is under arrest in the kidnapping of a 14-year-old girl from her home near Atlanta last month. The FBI nabbed Tony Maurice Graves on Friday. Graves is the third suspect taken into custody in the case, while investigators say a fourth suspect remains on the loose. Ayvani Hope Perez was abducted on September 17th after the suspects entered her home, demanded money and jewelry and shot the family dog. Her kidnappers released the teen a day later.
