The cause of death of fitness legend Richard Simmons is under investigation by the Los Angeles Police Department. The Medical Examiner's Office has deferred the case for further investigation, including additional testing which could take up to 3 months for an official ruling. Simmons passed away just one day after his 76th birthday, with no foul play suspected. Despite suffering a fall the night before, Simmons refused medical help and was found unresponsive the next morning. In a rare interview before his death, Simmons expressed gratitude for being alive and missed his fans, whom he interacted with through phone calls and emails. The reclusive fitness instructor had not been seen in public for a decade, but remained dedicated to helping people and connecting with his supporters.
