Joe Exotic was the "star" of the Tiger King documentary on Netflix that caught the public eye during lockdown. It was all anybody talked about for like a year.
Joe badly mismanaged a big cat zoo (tigers mostly) and Carole Baskin runs a tiger sanctuary. He constantly ranted about her trying to shut him down, and he claimed she had killed her previous husband Don Lewis.
Joe is currently in federal prison and running for president again in 2024.
In the documentary after you're introduced to the weirdness that is Joe Exotic, Doc, and Carole Baskin, you learn that Carole's millionaire husband, Don Lewis diseapeared out of nowhere and Carole did some shady stuff to get his money instead of his ex wife and kids.
To this day nobody know what happened to Don Lewis.
The most funny theory is that Carole feed him to the tigers... they snaking.
