Season 4: Episode 6 - Where in the World is Carmine O'Brien

Where in the World is Carmine O'Brien: ­When the body of a police officer is found dead, the CBI travels to a small resort town in the mountains in order to investigate. While on the case, Theresa Lisbon crosses paths with her younger brother, Tommy Lisbon, and his daughter Annabeth. Agent Lisbon is startled to learn that Tommy is a bounty hunter now, and he’s been tracking escaped fugitive Carmine Alexander since St. Louis. Once it starts to look like Alexander might be responsible for the cop killing, though, the Lisbon siblings realize that they’re both after the same man for completely different reasons.
