Trotter was declared dead Tuesday at a Chicago hospital after paramedics found him unresponsive in his home. An autopsy conducted Wednesday ruled out foul play or trauma, but the Cook County Medical Examiner's office said an exact cause of death could not be determined until toxicology tests and other tests are completed. It could take up to eight weeks.
In a statement to The Associated Press, Rochelle Trotter said the aneurysm was discovered in January and that doctors had prescribed the "proper medication."
According to a police report obtained by the AP, Trotter's family said shortly after his death that the chef had flown to Wyoming "against doctor's advice."
Rochelle Trotter disputed those suggestions, saying "medical experts" cleared him to travel and that he'd returned Monday night from his most recent trip. She also said "the autopsy indicates the travel is not connected with his death."
Trotter closed his world-renowned restaurant in 2012, saying he planned to study philosophy. But a friend of his, Larry Stone, has said that Trotter's health may have played a role in his decision to close the eatery after a quarter-century.
