Transcript for New ‘Tiger King’ documentary looks for clues in star’s disappearance
Back now with an ABC news exclusive. "Tiger king" star Carole Baskin is being sued for defamation by the daughters of her former husband who disappeared mysteriously more than 20 years ago. Now the new docuseries exploring new theories about the open case, and Amy is here with the first look. Good morning, Amy. Reporter: Good morning, Michael. That's right. It's called "Joe exotic: Tigers, lies and cover-up," and it may offer new clues in the investigation into what happened to Baskin's former husband, don whoa, oh oh Reporter: This morning, as Carole Baskin dances in the ballroom -- the family of her ex-husband, don Lewis, filing a defamation lawsuit against the "Tiger king" star. I keep it inside, and wait until everybody's gone before I can break down. Reporter: The family saying in the lawsuit, Baskin is currently appearing in "Dancing with the stars" and is complicit with jokes about don Lewis' death. For me, it was kind of sedated. Reporter: Lewis' daughter is pushing for renewed attention on the disappearance of their father. Do you know who did this, or if Carole Baskin was involved? Reporter: She has denied any involvement, but in the new docuseries, "Joe exotic: Tigers, lies and cover-up," they're taking a deeper dive, exploring new theories about what may have happened to don Lewis. One month and a day after don Lewis was reported missing, lo and behold his wife at the time went ahead and sold three properties to the handyman. The price for all three of them was $9,080. So essentially $3,000 per property. Reporter: They were reported at $100,000. Anything over $10,000 would have to be reported with a paper trail. Reporter: Baskin allegedly not telling police about the sale until three years into the investigation. Baskin claims the county evaluated the properties higher than the true worth and she was only trying to help the handyman get into real estate. She claims he failed to keep up with payments and re-deeded the properties back to her. Baskin has said she did not believe father did not have anything to do with don's disappearance. Police said they have no suspects or persons of interest. The docuseries also conducting a search for Lewis' body. Lo and behold, we have the cadaver dogs which are trained in human remains and they started alerting in and around the west side of that lake which is in close proximity to don Lewis' lakehouse. Reporter: The search ended without finding a body, but Baskin said, there is no one who wants to have the mystery of his disappearance solved more than I do. Joe exotic asking for a presidential pardon after conspireing to kill Carole Baskin who was his rival. Somebody that has a little bit of influence can get to our dear president and show him that this is wrong. Reporter: Now lawyers for Carole Baskin say they could not comment on pending litigation, but Michael, I think it's safe to say there is much more to come on all of this. Oh, absolutely, Amy. You can see parts one and two of "Joe exotic: Tigers, lies and cover-up" premiering on Instagram discovery this Sunday, and the finale on Monday.
