The Netflix documentary Joe Exotic, the founder of Greater Wynnewood Exotic Animal Park.
Divided into seven episodes, Tiger King documents the events that led to Joe's arrest and conviction for plotting to murder Baskin. Early on, both individuals speak about their respective businesses, with Baskin stating that “We are fixing the problem, they are creating the problem" and Joe calling her out for hypocritical statements and behavior. The third episode of Tiger King, "The Secret," is mostly dedicated to Baskin's backstory and various subjects' opinions about what actually happened to Lewis. Two days after the Netflix docies released, Baskin refuted all allegations and claimed that she was misled about the premise (via the Big Cat Rescue website).
Tiger King features a variety of entrepreneurs with questionable motives - including Joe, his former business partner Doc Antle - but the seven episodes heavily frame Baskin as the archetypal unreliable narrator. By questioning the woman's credibility from the start, Netflix sets up various revelations that essentially serve as murder mystery clues. Many Tiger King subjects believe Baskin married Lewis for financial reasons, and then killed him to capitalize upon his wealth. The foundation for Baskin's perceived guilt stems from her demeanor in Tiger King while answering questions about Lewis' disappearance. For example, she nervously giggles when addressing rumors that she put Lewis' body through a meat grinder and then fed him to tigers. ("People want to believe something that's just TOTALLY OUTLANDISH.") Baskin also speaks casually when discussing her ex-husband's disappearance, which can give the impression that she's cold and calculating, as implied by Joe and other interviewees.
Aside from Baskin's demeanor in the Tiger King, it's her behavior after Lewis' disappearance that makes her look guilty. A main talking point online has been her ex-husband's will and the power of attorney paperwork that Baskin produced. As revealed in Tiger King, the verbiage uses the line "Upon my disappearance," which implies that she was anticipating Lewis' being out of the picture for good. Interviewees also seems suspicious of Baskin for having Lewis declared legally dead five years and one day after his disappearance, which was the first day that she could technically gain control of his assets as listed in the will. It's also implied in Tiger King that Carol's brother, a police officer, somehow assisted her on the day that Lewis disappeared.
Following Tiger King, the Don Lewis case may be reopened, or at least that's what Chad Chronister, the sheriff in Hillsborough County, Florida, hopes. Other evidence has been brought futher into the public eye too. Robert Moor, who worked on a podcast about Joe Exotic, explained on Twitter that Jay Baykal, someone Carol dated after Don Lewis, but before Howard Baskin, had taken out a restraining order against her. In the court order, he claimed that he was worried about Don's disappearance, and when he asked Carole what she'd do if he turned back up, she replied: "A dead body cannot talk." The order as a whole, meanwhile, mentions that he thought she was dangerous.
The evidence against Carole Baskin, however, is circumstantial. And therein lies the reason why she published an essay to refute all allegation presented in Tiger King. Baskin reveals that Lewis' mental health declined significantly in the years before his death, and that interviewees in Netflix's Tiger King took advantage of him. Baskin also denies that Lewis was a "wealthy" man when she married him, and states that she used the phrasing "upon my disappearance" in power of attorney paperwork because Lewis had been loaning money to questionable acquaintances overseas. ("Our Costa Rican attorney, Roger Petersen, said the Helicopter Brothers were the local version of the mafia...")
Lastly, Baskin claims that Lewis was a sex addict who would leave the U.S. for sexual purposes ("He would go to Costa Rica during the week I was having my menstrual cycle"). Incidentally, she would remove "junk" that he'd been hoarding. When Lewis got upset, police allegedly told him that he needed a restraining order to get it back, which implies that it was a legal technicality and not the result of him being fearful for his life. Baskin also includes links to various legal documents to refute all allegations. Overall, she addresses various Tiger King interviewees by name and theorizes about their motivations, both in past business dealings and in the Netflix documentary.
