CHICAGO (CBS) – The deaths of two men initially believed to be possible victims of the cold were determined to be natural deaths on Thursday.
John Carson, 46, of the 9900 block of South Clyde Avenue, was found dead in his home on Wednesday. There was no heat working in his home at the time, according to the Cook County Medical Examiner’s office.
An autopsy Thursday determined Carson died of chronic alcoholism and his death was ruled natural.
