At age 10, Corey, 21, claims he was manipulated by his “abusive” stepmother, Judith, into shooting and killing his father — and telling police it was an accident. Judith is now serving a life sentence for aggravated murder and other charges, but Corey says he also blames his birth mother, Wendy, for his father’s death. Did she put Corey in harm’s way? Plus, a mother loses custody of her newborn child — is her sister to blame?

Ultimate Betrayal: Forced to Kill His Father

When Corey was only 10 years old, he was manipulated, he says, after years of torture and abuse by his step-mother, Judith, and forced to put a gun to his sleeping father’s head and pull the trigger. Corey kept the secret for nine years, claiming Judith threatened to kill him if he ever told the truth.

Eventually, though, Corey confided in a teacher, who reported it to the police. After an investigation and trial, Judith was sentenced to life in prison without the possibility of parole.

Corey details the abuse he suffered at the hands of his stepmother — and how she manipulated him into killing his father.

But Judith isn’t the only person Corey blames for his father’s death and for the life of abuse he says he lived. Corey says he also blames his birth mother, Wendy, who signed over her parental rights to his father and Judith when he was 8 years old. Wendy tells Dr. Phil she had no idea Corey was being abused and thought, instead, that she was giving him a stable family environment.

See why Corey holds Wendy responsible for his father’s death. And, Wendy faces her son.

Having heard their stories, Dr. Phil wants Corey to think about the future.

"There’s no way I can make sense out of this,” Dr. Phil says. "There’s nothing that I can say, or she can say or anybody can say that will make any of that OK. Nobody can give you back those years. Nobody can take away the pain and the hurt and the suffering and now the guilt you feel about what you did. And I’m telling you, your goal has got to be to forgive yourself.

“There’s a truth I believe that says, ‘The only thing necessary for evil to prevail is for good men to do nothing.’ And if you do nothing, if you just stay paralyzed and frozen, [Judith] wins."

"What does Corey want from Wendy? Do you want to spend the rest of your life hating her?"

"You have to set a goal and say, 'I am going to sort this out, and I am going to forgive myself. When you do that, you’ll find it in your heart to forgive her."

Dr. Phil offers professional resources to Corey, to help him with his feelings of guilt, anger and bitterness, and to help him build a new relationship with his mother, if he chooses. Corey and Wendy agree to participate.

Betrayed by Her Sister?

Michelle says she believes her sister, Tashena, caused her to lose custody of her 6-month-old daughter, who has special medical needs. Michelle says someone contacted CPS, claiming she and her boyfriend smoked weed and physically fought around their daughter — claims she denies.

Tashena denies contacting CPS but says she is happy that somebody did. She claims her sister's irresponsible parenting, including missing about a dozen doctor's appointments, is what is really to blame for Michelle losing custody. "I think I'm more attached to my niece than my sister is," Tashena says.

Has Michelle been doing all she can to get her baby back? Dr. Phil reviews her list of requirements.

Does Dr. Phil think Michelle is ready to get her child back?

Dr. Phil tells Michelle that he thinks Tanesha is trying to help her, not hurt her. He encourages Michelle to continue working on her list of requirements to get her daughter back.
