IntroductionKing Courney tells you Cisco's eating at a restaurant in town and he thinks it's the perfect time to take him out.
Beat Him With Your Bare HandsDrive to the restaurant in the park. When you arrive, you'll see his guards out front. There's six of them. I'm sure they wouldn't be too difficult to kill, however I preferred to walk around the side of the building and avoid them.
After the cutscene with Cisco, he'll want you to fight him. Whip out a gun and give him a few blasts. Once his health is all of the way down, he'll talk to you and eventually invite you to go back to his place for further discussions about the death of Vinnie.
