Marna’s daughter, Kristin, claims her mom “constantly lies about things that sane people don’t lie about.” She says Marna tells people she works as a phlebotomist at a hospital and has a history of faking cancer. “My mom has told me that she has had breast cancer, lung cancer, thyroid cancer, and melanoma.”

Kristin says she doesn’t think Marna’s fiancé, Mark, knows the truth about her mother and she says that’s not fair to him. “My mother is 100% lying about everything - all the time – and she needs to come clean.”

When Dr. Phil sits down with the three of them, Marna admits there are things she’s been keeping from Mark, as well as Kristin, including the fact that she’s been arrested three times for driving under the influence.
