Lydia Faulk

Lydia Faulk is the hidden villainess from The Mentalist episode 6.20: "Il Tavolo Bianco."

She was played by Merle Dandridge.

Lydia Faulk is a corrupt prosector who made a monetary deal with Jon Ocardo, who killed a man named Elijah Macey. She tampered with the grand jury and presented the case in such a fashion that Ocardo would avoid indiction. To catch Lydia, a sting was set up which included Patrick Jane testifying over his role regarding the death of Thomas McAllister, aka notorious serial killer Red John.

After Ocardo was finally indicted, Lydia was confronted with evidence of her meeting with Ocardo, as well as a large sum of money deposited in an offshore account in her name. With the mounting evidence against her, the evil Lydia ended up arrested for tampering with the grand jury.
