Grand Theft Auto: Vice City/Treacherous Swine

Colonel Cortez will explain to you that Gonzales, his right hand man, took your money. He'll give you a chainsaw and tell you to kill for retribution. Drive to the dot on your map and park your car near the open doors of the building. Tommy will go in the building and a cutscene begins. Gonzales tries to escape and Tommy must chase Gonzales out of the building. (There will be a hidden package near where you start on the building.)

Ignore Gonzales' protests, and when he starts running, catch up to him and saw him up or run Gonzales over. Afterward, go to the Pay 'n Spray (if you haven't used it already, it will be free). You will lose the wanted level and you will have beaten the mission.
