Each week on the podcast, Taberski -- who says he was Simmons' friend -- interviews an array of people who knew the Sweatin' to the Oldies star in hopes of speaking with the once-outgoing celebrity and thus getting a better understanding as to why he stepped out of the spotlight in the first place.
"The podcast explores all the possible reasons Richard Simmons would stop being Richard Simmons. And some of them are outlandish. Some of them make total sense. And some of them are a little sad," he explains during a phone interview with The New York Times
. "I have my own theory, but we get to that toward the end. And it’s not really something that people have discussed, and it speaks less to this sort of weird mystery that nobody ever wanted in the first place."
In the third episode of the podcast, Simmons' former friend and massage therapist, Mauro Oliveira, alleges that the 68-year-old fitness instructor
is being held hostage by his longtime housekeeper, Theresa Reveles, who lives in Simmons' Hollywood Hills home and is said to be his closest confidant. Simmons' rep, Tom Estey, has vehemently refuted
Oliveira's accusations, calling them "a load of crap."
"It’s possible, for sure. I think our skepticism of the more outlandish parts of that theory are clear in that episode," Taberski says of the theory. "It had been reported before, and others who know Richard didn’t dismiss it out of hand, so we clearly needed to raise it."
He adds, "But I also think Richard’s friends are genuinely, deeply concerned for Richard and the eerie wall of silence around him. That is very real."
"There is no issue for the police to be involved with," an LAPD detective said. "Mr. Simmons simply wants privacy."
Taberski disagrees. "The concern is that he is not just taking time off. He’s not just retired. He’s not just stepping away from the spotlight. The concern is that he’s cut off every person he knows. It’s impossible not to be concerned about that," he tells the Times. "And every person I’ve talked to, every friend who’s known him for years, everybody is concerned."
ET also spoke with Oliveira
about what he thinks led to Simmons' retreat from the limelight. "He used to have friends over all the time, dinner parties all the time," he recalled. "That's why it bogs my mind that he decided to 'completely abandon the world.'"
Oliveira told ET that he believes Simmons has been "terribly advised" by the people around him. "They are doing a terrible job to take care of his legacy of himself," he said. "To take care of the amazing life that he had helping people."
