Patricia "Tricia" Thornburg was the daughter of Brooke Thornburg, the stepdaughter of Judge Thornburg, the older half-sister of Josh and the biological mother of Brian. Her biological father left her and her mother when she was five, her mother got a job where she met Thornburg and have been married ever since.
At 11 years old, Tricia had sex with her stepfather and had a son with him, Brian, a year later. Since then, she had been a troubled girl, but had been really crying out for help.
She was killed by her mother after she told her that the father of her grandchild/adoptive son is Walt Thornburg.
