Ray Machowski

Ray's cover is blown. Claude smuggles the marked cop across Staunton through Cartel and police roadblocks, gets him to Francis International, and onto a flight out.
Marked Man is the final mission in given to protagonist Claude by corrupt police officer Ray Machowski from the toilet block at the Belleville Park district of Staunton Island, Liberty City.
Claude drops by the toilet block in Belleville Park. Ray tells Claude that he is a "marked man" and needs to escape Liberty City. He wants Claude to take him to the Francis International Airport so that he can catch his plane out of the city to Miami. If Claude successfully drives Ray to the airport, Ray will reward him some items.
Claude and Ray have three minutes to their way to the airport. However, the Shoreside Lift Bridge is guarded by CIA officers (who are armed with M16s and are able to survive up over twice the amount of damage), so Claude finds an alternate route, one being the Porter Tunnel. Claude drives through the Porter Tunnel, and he and Ray eventually reach the airport to allow Ray to catch his flight. Once they reach the airport, Ray gives Claude the keys to a lockup in Newport, and enters the airport. Claude drives back to the lockup and when he arrives, Ray pages Claude asking him to take care of the bullet-proof Patriot. Other equipment, including a rocket launcher, a sniper rifle, an M16, and a flamethrower, as well as some money, are also stored in the lockup as a gift from Ray to Claude.
