The Mentalist Season 2 Episode 22

At a San Desidera, California Human Rights conference, Sheltering Light Foundation against human trafficking leader Hector Brava has his skull smashed with a hotel fire extinguisher just before his speech. According to his researcher and PA Russell Bigelow, he was to expose that Christopher Lynch's World Anti-Traficking Coalition is a front for traffickers eliminating their competition. Patrick soon realizes Hector and his widow Ilsa Engels reproached each-others affairs, he perhaps with the mysterious Carmen whose call lured him to the murder place. Patrick is most skeptic about collaborating with 'psychoic analyst' Kristina Frye, whom sheriff Andy Burnside enlisted.
