On June 15, 1984, 15-year-old Reesa was brutally murdered in her grandparents’ house. Her 13-year-old sister, Jodie, immediately became a suspect, and Jodie says townspeople continue to gossip about her today, 34 years later, although Jodie adamantly denies any involvement in her sister's murder.

Laura, whose father was the police captain at the time of the murder, says she’s convinced Jodie killed Reesa, and she’s ready to be the voice for Reesa.

“My recollections of Reesa is that she had a heart of gold, always had a kind word to say to people. Jodie, on the other hand, seemed very dark. Jodie was the black sheep of the family,” Laura claims. “There was a lot of competition and tension between the two sisters. There was one time in particular I overheard her say to her sister, ‘I hate you. I just wish you were dead.’”

Laura continues, “What always seemed to bother me about Jodie is that she is more interested in clearing her name versus trying to find her sister’s real killer.”

Dr. Phil questions Laura about her claims. “You think you’re sitting across from a murderer?” he asks.
