The Sheridan County Coroner's Office has confirmed that an autopsy performed on 33-year-old Felipe De Jesus Aragon shows that he died of hypothermia that was brought on by exposure to the elements. Aragon was found over the weekend in the Big Horn Mountains after he was reported missing in February. Aragon had been working at Bear Lodge Resort at the time of his disappearance. Full results of the autopsy won't be available for several weeks. Officials haven't ruled out the possibility that alcohol played a role in Aragon's death.
