Julio Ochoa is the current 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 in the Higgins Helitours. The closest he came to an appearance was in The Lost and Damned, while Thomas Stubbs III receives a call on his cellphone from Johnny Klebitz, while Stubbs is in a meeting with the mayor. Jon Gravelli claims he was going to receive a visit from him in the Hospital, he also claimed that he was going to receive a visit from two US Senators.
Ochoa has a campaign to remove the sale or possession of firearms from the city and launched cases against Ammu-Nation stores across the country, these regulations, however, have proved massively ineffective to prevent crime.
During a HeliTour, the pilot mentions to Niko and the other tourists that Ochoa eased safety restrictions on helicopters and their pilots. Julio Ochoa also settled the Diamonds case when he allowed Jerry Kapowitz to keep all proceeds on the sale of the diamonds after he found them, despite over a hundred claims of their ownership. The reason given was that it would be impossible to verify the claims. It would make him extremely unpopular with a number of people in the Liberty City underworld. Apparently, his term may have ended as of the events of Grand Theft Auto: Chinatown Wars as Ammu-Nation is again up and running, although it is a WebSite.
