Original Story:

Officials have issued an Amber Alert for five-year-old Porter Stone. The little boy was at St. Louis Childrens' Hospital. He is on the list for a heart transplant.

Officials say his father, Jeffery Stone, took the boy as he was in the process of being discharged. Police say Jeffery Stone took Porter to his car and called the mother, who was still at the hospital, saying he was taking the boy.

Stone does not have legal custody of Porter, and police say he left without any of the medicine the boy needs.

They were last seen in a silver four-door Toyota Corolla with California plates.

Investigators think Jefferyâ??s mother is also in the car.

Porter was last seen wearing a grey tee shirt, black and white plaid shorts and Spider Man tennis shoes. He was also carrying a back pack that contains medical equipment.

Jeffery Stone is described as about 6-feet-6-inches tall and weighing 230 pounds. He has a shaved head and was last seen wearing a grey shirt, black shorts and a San Francisco Giants baseball cap.
