- "Listen to this music, and stop stealing cars! Bang the women, not the gangs! In my day, well, different kind of gang-banging."
- ―Sergio Boccino
Sergio Boccino is a Radio DJ on Double Clef FM in 1998, the setting of Grand Theft Auto: Liberty City Stories. His station was the favorite of the Leone Family, the Forelli Family and the Sindacco Family. As of 2001, the setting of Grand Theft Auto III, Morgan Merryweather replaces him as DJ of Double Clef FM.
He is heavily disliked by Morgan Merryweather for, in his words, "being an over-emotional pedophile with a terrifying Oedipus complex and a complete misunderstanding of the music he plays".
Also, according to Morgan Merryweather, Boccino is a "holder of loads of pornographic material that could get him deported from the city".
He is voiced by Robert Blumenfeld.
