Kelly claims when she was 11 years old, her father began grooming her to be his “wife.” She says her father made her iron his clothes, have food on the table when he got home from work and maintain the house they shared with her other siblings.

Then when she turned 12, she claims her father forced her to become his sex slave.

“I was raped by my father and basically held prisoner in my own home for 12 years,” says Kelly, who claims she gave birth to two children fathered by her father. “My dad brainwashed me, manipulated me and he threatened me so I would stay quiet.”

“How did this happen?” Dr. Phil asks Kelly. “How did people in your world, people in your life, your mother -- how did somebody not step up and say, ‘This just looks wrong. This relationship doesn’t look right?’"

“A lot of people had suspicions and nobody spoke up,” Kelly says. “I feel let down from those people, kind of.”
