Procure a Luchadore vehicle and head to Sunset Park to pick him. In case you killed the decoy, just chase the other marker and kill the target. There will be two targets that will appear in the map. You should grab a police car and pull him over in Ashwood to execute him. No worries though since they'll be walking towards you anyway. Only one is the real target and the others are decoys. Grab her like what you normally do to get a human shield and several markers will appear. Just drive slowly around the district until you spot one of those hos walking around. Grab one of his fat, ugly hos in Henry Steel Mills to make him show up. Just spot some Luchadors, keep killing them until Almonzo appears as reinforcement. Harass his Luchador buddies in The Grove for him to show up.

Since you can't fire while driving a cart, you must immediately disembark and shoot the target's cart until it explodes. More targets will become available as you progress through the story so make sure to come back and check your Saintsbook regularly.
