Julio Ochoa is the currently serving mayor of Liberty City. His most notable works have been done in 2008. He does not appear through the game but is mentioned frequently in the in-game media, such as online websites and also during some missions and one of the helicopter tour. The closest he came to an appearance was in The Lost and Damned, while Thomas Stubbs III receives a call on his cell phone from Johnny Klebitz, while Stubbs is in a meeting with the mayor.
Ochoa has a campaign to remove the sale or possession of illegal firearms from the city and launched cases against Ammu-Nation stores across the country. During a helitour, the pilot mentions to Niko and the other tourists that Ochoa eased safety restrictions on helicopters and their pilots.
