Roger Murtaugh - Lethal Weapon 3

Lethal Weapon 3

Murtaugh and Riggs mishandle a car bomb, which destroys a building. As puinishment, both are reduced in rank to patrolman, but regain their previous rank when they foil an armored car robbery and reveal a gun running cartel. While investigating this cartel, Murtaugh kills a fifteen-year-old boy to save Riggs' life; the boy is revealed to be a friend of Murtaugh's son Nick. Murtaugh is overcome by guilt and turns to isolation and alcohol until Riggs helps him forgive himself. Murtaugh helps Riggs and Internal Affairs officer Lorna Cole (Rene Russo) destroy the cartel. As a comical sidelight, Murtaugh also helps Riggs quit smoking by giving him dog biscuits instead; he does show some anger towards Riggs, however, when he believes that Riggs is becoming romantic with his daughter Rianne.
