According to celebrity news website TMZ, Beth is suing Oxygen because of the false claims they made over her daughter's whereabouts.
She believes that she was tricked into giving her DNA when the reality is that they never found a body. Beth is reportedly "horribly embarrassed" and would've never taken part in the show had she known that they were more interested in the ratings than giving her family closure.
She described the series as a "pre-planned farce" and also filed a lawsuit on behalf of her daughter using a legal theory called "outrage."
Beth's stance on how the events unfolded is very different from Dave, who was the one that struck the deal with Oxygen.
In a previous interview with InTouch, Dave said he was only interested in the new findings because it could be a "real, plausible lead," and that he wouldn't involve his family, including his ex-wife, Beth, unless it was legitimate.
He recalled his previous involvement in the pursuit of another lead back in 2015, to further drive his point home.
"How many of those things can you go through? I swore to myself — right then — that I would never involve my family and lay out their emotions on a lead ever again. And when this one came up, I briefly mentioned it and I slapped my mouth,” he said. “I said, ‘Look, no matter what, I can’t bring my family into this and expose them to another potential devastation.’ So T.J. and I kept it among ourselves, and I said to myself, ‘If anyone is going to take the fall for this, it’s going to be me. I’m not going to allow my family to even know about this and eve get involved emotionally only to be crushed again.’"
It's unclear whether or not Beth's lawsuit also named Dave since details surrounding the court case are scarce.
