An autopsy conducted on celebrated chef Charlie Trotter was inconclusive, but officials have found no evidence of foul play or trauma.
The Cook County medical examiner's office said in a statement on Wednesday that it will conduct additional tests, including a toxicology analysis, to try and determine a cause of death. The results could take six and eight weeks.
An ambulance was called to Trotter's home about 10.45am on Tuesday after Trotter's son Dylan found him unresponsive, according to a police report. Trotter was taken to Northwestern Memorial Hospital, where he was pronounced dead.
The family told police that Trotter was taking medication for seizures, high blood pressure and high cholesterol. He had flown to Jackson Hole, Wyoming, against doctors' orders to address a culinary conference on Sunday night, according to the reports.
"He got on a plane this weekend and his son found him unresponsive this morning," a police report stated.
