Terrie says in 2017, her daughter, Kelly, accused her of molesting her 5-year-old daughter, Terrie's granddaughter. Terrie insists this is completely untrue and insists she has never molested anybody. Terrie says Kelly is tearing apart the family with her horrific accusations. Terrie says just before Kelly's accusations began, she attended a week-long desert retreat that she believes completely changed her daughter's personality. Terrie says Kelly tells people she saw aliens on the retreat who may have abducted, raped and impregnated her. Kelly says she is 100% convinced her mom molested her daughter. She claims her mom is a serial child molester who has also molested her and her sister, Katelyn, which Katelyn and Terrie say is completely untrue. Kelly says she is tired of her mother using the desert retreat as a means to tell everyone in the family that's she's "crazy." She's hopeful that with Dr. Phil's help, she can finally expose her mother, whom she hasn't spoken to in over a year. Did Terrie molest her granddaughter? Is Kelly just confused?
