After the cut-scene go get a fast car, then go to the Washington Mall. Park by the North exit (the exit facing the sea). You will meet a French guy upstairs in the mall. The French guy will run and SWAT will be after you in the mall only. Do not bother trying to shoot the SWAT guys, just get out of there as fast as you can. The Courier will exit towards the north, take your fast car and hit the French guy's motorbike. Then, if he is not dead run him over with your car again before he gets on his bike. Collect the suitcase floating above him, you will have 2 wanted stars at this point. Return to Colonel Garcia at the port to complete mission.
