Joanna Lyle (The Mentalist)

Joanna Lyle (Amy Pietz) is the main villainess from "Days of Wine and Roses," episode 5.11 of The Mentalist (airdate January 6, 2013). She worked at Oasis Ranch, a rehab facility, and served as the personal drug counselor for Charlotte "Charlie" Coates, a model and Congressman's daughter who was at the facility due to her drug addictions.
During her first encounter with Patrick Jane, Joanna revealed that she is a recovering alcoholic, but it was also later revealed that she is a compulsive gambler. Joanna racked up massive debts due to her gambling, which persisted even after losing her house and her kids' college fund, and she borrowed money from unsavory people. When she found out about Charlie stealing a valuable ruby necklace that belonged to her mother, the scheming Joanna saw it as a way out of her financial woes and planned to steal it.
Charlie had felt guilty about stealing the necklace (which was worth at least $250,000) and had wanted to return it. Joanna used Charlie's guilt to her advantage, manipulating her into sneaking out with the necklace and telling her that she should return it during her 30-day chip ceremony. Joanna drove Charlie out of the facility and stopped at a nearby park where addicts often score drugs, doing so under the false pretense that one of her tires just went flat. She sent Charlie to check on the tire, and at that moment, the evil Joanna grabbed a flashlight and bludgeoned Charlie to death before taking the necklace. The villainess committed the murder at the park to make it appear that Charlie was killed looking to get high, and after the murder, Joanna hid the jewels inside a wood stove.
After Jane passed himself off as a kleptomaniac at the facility, Cho informed Lisbon that a ruby necklace was found in Jane's car. Joanna went to the wood stove and found the necklace there, and it was there that Cho caught her. She later confessed to the theft and killing Charlie while being interrogated by Rigsby, who called out Joanna for making Charlie's parents believe that she did while looking for drugs. In response, Joanna blamed her addictions for her decisions, stating that she was powerless and that her addictions were a disease. Joanna was later arrested (off-screen).
