The team arrives at a bridge in Sacramento to investigate the death of Kristen Marley an intern for Senator Melinda Batson. Jane rules out Kristen's death as a suicide when he notices she's wearing one shoe while the other is missing. There are a number of suspects in this case. There is a rumor that Melinda's husband, Elliott was having an affair with Kristen, but Jane discovers that Walter Crew, Melinda's father was the man Kristen was having the affair with. Going through phone records from the night of the murder, the team brings in Harlan, Kristen's step brother who was released from a carjacking arrest the night of her murder. While in questioning, Cho and Rigsby find Kristen's missing shoe in Harlan's trunk. Harlan still maintains his innocence, saying the shoe was planted. Jane, claiming he'll deliver the real killer in 12 hours, gets Lisbon to hold off on booking Harlan for Kristen's murder. Jane discovers a bug in one of the lights. He traces the bug back to Art Cavalleri, a private investigator hired by Walter Crew who posed as the CBI janitor and was responsible for Kristen's death. Art escapes Jane & Lisbon but is killed in a car chase. Using Art's body as a bargaining chip, Lisbon brings in Elliott and Melinda Batson and Walter Crew for questioning, offering leniency if they confess to any of the details relating to Kristen's death. Elliott steps forward, admitting to his arranged marriage and Melinda's affair with Kristen. Kristen broke it off with Melinda, favoring Walter and when Melinda found out about her affair with her father, she killed her and her father helped cover it up. With the case closed, Jane makes a peace officering to Bosco and his team, but uses the opportunity to bug his office and listen in on their progress of the Red John investigation.
