Just after Riggs frees Murtaugh and his his daughter, Rianne (Traci Wolfe), Joshua follows Riggs, Murtaugh, and out of the disco club and into the street. He steals a car, and Riggs and Murtaugh chase after him on foot. With a bullet in the shoulder, Murtaugh cannot keep up, but he notices that Joshua is headed for the freeway and tells Riggs to take the third Street bridge and cut him off. Riggs machine-guns Joshua's car, causing it to burst into flames. Joshua ditches the car, steals an Audi, and speeds away. Meanwhile, Murtaugh decides to go after McAllister, who is also making his getaway. To get away from Murtaugh, McAllister steps on the gas while pulling out into the street and is broadsided by a bus. The car flips over and bursts into flames, roasting him alive. Riggs catches up with Murtaugh and informs him that Joshua got away. Realizing that Joshua is probably going after his family, Murtaugh commandeers a patrol car, and he and Riggs head to the house. Joshua has already made there and shoots the two officers assigned to watch the Murtaugh home. Joshua breaks into Murtaugh's living room but finds no one at home. Suddenly, the patrol car bursts through the living room wall. Joshua shoots at it, but there's no one in it, because Riggs is standing right behind him with a gun pointed at his head. Riggs and Joshua go at it hand-to-hand on Murtaugh's front lawn, with Murtaugh taking command of the situation, letting Riggs "arrest" Joshua himself. The 2 battle until Riggs wins, clenching Joshua in a leg-scissor hold until he passes out. As the police haul Joshua away, however, he grabs the gun from the policeman's holster, forcing both Riggs and Murtaugh to shoot him first. In the final scene, Riggs puts flowers on his wife's grave then stops at Murtaugh's house to give him the hollow-tipped bullet he'd saved to commit suicide because he won't be needing it anymore. Murtaugh invites him in to partake of the world's lousiest Christmas turkey, Riggs invites in his dog Sam, and Sam and Murtaugh's cat Burbank immediately go at each other. 'I'm too old for this,' Murtaugh says as he closes the front door.
