Jayden Morrison disappeared while his family was visiting his grandmother in Little River. His mother went shopping and left her three children at the house, and minutes later, around 5:30pm, his grandmother noticed the door ajar. The search began immediately. "We've always been in a gated situation," the boy's father, told reporters on Christmas Day. "We knew he was a wanderer when he was younger, but he was always in an enclosement. We never put him in a position to go out and freely wander." Investigators believe the non-communicative boy wandered into the water shortly after he was reported missing, NBC News reports; an autopsy shows that he drowned.
