A prosecutor says the preliminary autopsy results in the death of a 2-year-old West Tennessee boy who was missing for a week before his body was found show he died of hypothermia. Media report District Attorney General Jerry Woodall issued a statement Monday and said there were no signs of foul play in the death of Noah Chamberlin of the Pinson community. The child's body was found Thursday in a clearing in the woods near his home. The boy went missing during a walk with his grandmother and 4-year-old sister. Hundreds of volunteers were involved in the search. Final autopsy results will take eight to 16 weeks. The child's funeral is set for Wednesday.
