A 4-year-old boy with autism who went missing from his grandmother’s house in South Carolina on Christmas Eve was found drowned in a nearby pond on Friday. Jayden Morrison, of White Plains, New York, was found in a retention pond in Little River, in the same pajamas he wore when he was last seen. Morrison’s mother had left to Wal-Mart on Christmas Eve and left the boy in the care of his grandmother. Drones, helicopters, and four-wheelers were used in the search, which lasted through Christmas Day. “Our thoughts and prayers are with the Morrison family at this difficult time,” Horry Conty Police Department Lt. Raul Denis said in a statement.
