Judas on a PoleEdit
Robert Kirby suspended Special Agent Seeley Booth for bringing up the issue of Marvin Beckett being released after being falsely arrested for the murder of Augustus Harper, an FBI Agent. It is later revealed that Kirby killed Agent Harper and tried to kill Russ and Seeley. Later, Booth and Temperance Brennan find a pool of blood at her house which is found to belong to him. Max Keenan stabbed him with a Misericorde, gutted him, and set him on fire postmortem on a rooftop and is later arrested for Kirby's murder. Max however is acquitted due to his lawyer making it sound like Temperance also had a motive, means, and opportunity to kill Kirby, resulting in Max's release.
