HAMPDEN, Maine (AP) – The Maine medical examiner’s office says a Hampden teenager whose body was found near a gravel pit last March died of hypothermia.

The cause of 17-year-old Nathan Clark’s death was withheld for nearly five months pending the results of out-of-state toxicology tests. His death is listed as an accident.

The Bangor Daily News says it’s unclear if the autopsy results will have any impact on a criminal case stemming from the investigation into Clark’s death.

Police say Clark had attended a party at the home of 44-year-old Michael Joseph Fortunato before he went missing. Fortunato, of Hampden, is charged with furnishing marijuana and muscle relaxers to teenagers, as well as letting a minor possess or consume alcohol in his home.
