The death of Richard Simmons is under investigation as the LAPD awaits the medical examiner’s report. Simmons, who died Saturday, a day after his 76th birthday, was discovered at his L.A. home.

“We are awaiting the final cause of death ruling from the coroner’s office before we can officially close the case,” said Norma Eisenman, LAPD public information officer. The test results could take up to six weeks.

In an interview with People magazine days before his death, Simmons expressed gratitude for being alive. “I am grateful that I’m here, that I am alive for another day,” he said, adding that he planned to spend his birthday helping others.

Simmons, who had been out of the public eye for over a decade, had always downplayed his celebrity status, describing himself as shy and introverted. In 2016, he called into NBC’s “TODAY” show to dismiss rumors that his housekeeper was holding him hostage.

“No one is holding me in my house as a hostage. You know, I do what I want to do, as I’ve always done,” Simmons asserted.

In 2017, the podcast “Missing Richard Simmons” explored his withdrawal from public life.

A day before his birthday, Simmons thanked fans for their birthday wishes on social media, expressing his gratitude for the overwhelming messages.

In March, Simmons raised alarms with social media posts about being diagnosed with basal cell carcinoma, which he later clarified was from years ago, urging people to get screened.

A cryptic message posted days before claimed he was dying, but Simmons later clarified he was trying to be inspirational, urging people to embrace every day.

“Sorry many of you have gotten upset about my message today. Even the press has gotten in touch with me. I am not dying. It was a message about saying how we should embrace every day that we have. Sorry for this confusion. Love, Richard.”

Earlier this year, Simmons also made headlines for criticizing two movies about his life starring comedian Pauly Shore.
