12. Brown Shag Carpet

Complete story — includes the ending

Continuing their investigation into the serial killer introduced in the previous episode, the team convinces a reluctant Jane to appear as a guest on a number of television and radio broadcasts as a renowned psychic. During one radio show, he's contacted by a mysterious man identifying himself as "Lazarus" who cryptically discusses information on the case. The FBI realizes that Lazarus is indeed their killer, but find nothing but a rigged landline at the triangulated coordinates. Jane and another FBI agent are rammed by a car outside the radio station, with Jane being abducted by Lazarus. The killer, whose name is Joe Keller Jr., attempts to use Jane to communicate with the spirit of his serial-killer father and reconcile with his violent instincts. While Keller periodically leaves the house Jane is being kept in, Jane uses his resources to uncuff himself and set up a trap for Keller. This results in Keller being lured into a storage room, where Jane triggers an explosion using a lightbulb and a piece of chewing gum. Lisbon arrives at the house right as it explodes, but is able to rescue Jane from the wreckage.
