For the past 2 days, I've been listening to this great podcast called Missing Richard Simmons by Dan Taberski. In it, Dan explores the odd disappearance of Richard Simmons (who has been missing for a few years -- at least in public -- and the unfortunate people/friends Richard has sort of "left behind". It's a tragic story with a few really interesting twists. I would highly recommend subscribing. New episodes are still coming out weekly.
