Well… Jimmy Pergorino suspects Ray Bonicco of being a snitch, and so it is your job to deal with him (and his body guards). You can complete the GTA 4 Mission Pest Control. Follow the simple steps below
Start the mission by going to Jimmy Pergorino, skip the cut scene and about 2-3 minutes later you will receive a call from Jimmy, telling you to kill Ray.
Kill Ray and his guards before he gets to the chop shop. To help you a little bit, Jimmy (who is still a little of a friend of Ray’s) tells Ray to fill up his car at any gas station (this is where you should plan your attack to take place).
When Ray and his guards arrive at the fill-up station, park you car across the street, take cover behind your car, and let the fireworks commence. Aim for Rays car to begin with, which if the RPG hits, should ignite the station pump, which should in turn either blow up or light their car on fire, which will blow it up.
Note
If you put one of Packie’s car bombs on Rays Car, you can aim for the guards car and explode Rays car later.
