PEORIA, Ill. -- A Peoria County Coroner's jury ruled Tuesday afternoon councilman Gary Sandberg's death to be 'natural' in nature.
Sandberg was found dead in his Adams street home on July 19.
Peoria County Coroner Johnna Ingersoll said an autopsy showed that Sandberg died of heart disease, with heat stress as a contributing factor.
She said it was 97 degrees in Peoria the day Sandberg's body was found in a state of decomposition. She added that nothing was detected in toxicology tests.
Sandberg was found on the second story of the building, which was undergoing renovations. Johnna said the area where he was found had no fan or air conditioning and only had one partially opened window.
It is unclear how long Sandberg could have been in the apartment. Ingersoll said that cell phone records indicate his last outgoing call was made in the early evening of Sunday, July 14. That is five days prior to his body being found.
A Peoria Police detective said no trauma was found to Sandberg's body and there is no criminal investigation at this time.
