An autopsy today determined that the death of an 80-year-old south suburban man was due in part to the severe weather, authorities said.
Elias Contreras, of the 2200 block of Olive Street in Blue Island, died of hypothermia and cold exposure, according to the Cook County medical examiner's office.
A secondary cause of death was listed as heart disease and diabetes and his death was ruled an accident, according to the medical examiner’s office.
Contreras was pronounced dead at Metro South Medical Center in Blue Island at 9:15 p.m. Monday after he was found unresponsive at his home, according to the medical examiner's office.
Blue Island Deputy Police Chief Michael Cornell said a relative returned home and found Contreras outside on the back steps of his home about 7 or 8 p.m. Monday.
Contreras, who was inside when the relative departed an hour or two before, had possibly had fallen and he was not dressed for the severe weather, Cornell said.
