Live Free or Die Hard
Russo firing his Beretta Px4 Storm at the MP guards
Russo was in the Hazmet truck with Emerson and two other henchmen when they arrived in Woodlawn. He killed two MPs guarding the main gate in Woodlawn and secured it so that they can download the finanical data.
Later, Gabriel sends him to Camden, New Jersey to kidnap John McClane's daughter Lucy, posing as a FBI agent sent to rescue her. Russo brings Lucy to Woodlawn, despite resisitance and a punch to his face from her.
Russo then checks out an alert in the third sub-basment floor. He spots McClane and computer hacker Matt Farrell and helds them in gunpoint. But McClane managed to overpower him. Then, McClane pushes him into the office chair and tosses him down the stairs, breaking his neck, but not killing him. McClane confronts Russo into revealing where Lucy is, but refuses to do so. Gabriel tries to contact Russo, but McClane mocks that he is going to meet Gabriel's dead girlfriend, Mai Linh. Russo tries to reveal where McClane is to Gabriel, but McClane fires a shot, pretending to kill him to scare Gabriel. McClane takes his pistol and ammo and leaves him in the stairway. Russo's fate afterwards is unknown.
