First go to the stairs by the resturant on the second story when you first come out of the security room. Go halfway up and jump on the blue marquee follow it and you will see a bear a box and orange juice.

Keep following to find an uzi jump down and head toward the store but don't use the uzi. When you get the store you will see a cutscene. Right after jump on top of one of the aisles because he will try to run you over.

When he stops start blasting with the uzi. When you run out of the uzi wait till he stops and jump down to hit him with a sledge hammer or 2 by 4. One or two hits should do.

BE CAREFUL: HE HAS A SHOTGUN
