Jimmy Cast is, in 2008, an organized crime expert who lives in Liberty City. He told the Liberty Tree that "Mobsters are all vain - this war is not only a war for financial power, it is also a war for social control over the city. Expect more bodies to turn up before things calm down. The Alderney mob are known to be lawless and I imagine the older families will also be nervous as the DA's office uses this as an opportunity to indict several mobsters across the city in another massive crackdown on organized crime."
Cast is also apparently an author of non-fiction books, one of which has been made into an award winning Vinewood movie. The movie is called Mafia.
