Jon Gravelli Jr. is an unseen character in Grand Theft Auto IV.


He is the son of Jon Gravelli, Don of the Gambetti Family.

He was disowned by the Gambetti organization due his development of a cocaine addiction. According to the Liberty City Police Database, he is currently in police custody. Although he is heavily in debt and no longer considered part of the Gambetti Family, his father has ensured that no one attempts to collect on his debts.

Jon has been arrested three times: once in 1995 for possession of a controlled substance (cocaine), again in 1998 for possession of another controlled substance (crack cocaine) and finally in 2004 for armed robbery.
