(Riverton, Wyo.) - Fremont County Coroner Ed McAuslan said Friday that preliminary autopsy results on 60-year-old Thomas Ybarra, who was found dead in his apartment in the 800 block of East Adams, indicated a combination of hypothermia, acute alcoholism and pneumonia.

McAuslan said he is awaiting toxicology tests to determine if the cause of death was accidental or of natural causes. “There is nothing suspicious in the death,” he said.

The Riverton Police were investigating the case as a homicide unless autopsy results showed differently. The case has not yet been closed.
