The Mentalist Episode 2.04 Red Menace

The team is called out to investigate a carjacking homicide, but some details make them think it's more personal. The victim's name is Gordon Hodge, a lawyer to the motorcycle gang Sinner Saints, one of the top gangs in the state. The investigation begins with gang members who deny any involvement. Jane focuses his attention on the leader Von McBride but is unable to get any information out of him. However he does begin to plant the seed that there's an informant amongst them. Von's girlfriend Diamond becomes their first suspect when they uncover the affair she was having with Gordon. Diamond denies having anything to do with the murder, citing that if Von knew they would have found her dead body as well. She does divulge that the only other person that knew about the affair was Gordon's wife, Nina. Early on in the investigation a woman showed up at the Saint's bar screaming murder, but no one claimed to know who she was. Looking into the vandalism of Gordon's office, they discover it's the same woman, Felicia Guthrie who blames McBride for the murder of her brother as well as Hodge who as McBride's lawyer was able to have the murder case dropped. Jane has Felicia wrongly accused of Hodge's murder by planting his missing cufflink in her dumpster. Under arrest, Hodge's wife and his son, Lucas are called down to CBI to witness her booking but Lucas breaks down and confesses to the murder, unable to allow Felicia to take the blame. Jane's tale of an informant among the gang members pays off when he tricks McBride into looking like the informant.
