Enzo Bonelli is a minor character in Grand Theft Auto V.
Bonelli is the leader of a powerful, unspecified crime family that operates in Los Santos, who used his criminal connections to become a real estate developer by securing the majority of all city contracts through extortion, murder and labor racketeering. His hostile takeover left most of the city's older real estate firms in ruins including Gold Coast Developments, a firm in which Lester Crest has a great sum of personal stock.
To keep Gold Coast from going under, Lester hires Franklin Clinton to assassinate Bonelli at his construction site in Downtown Los Santos. However, Lester's contact within Bonelli's organization betrays him and informs Bonelli of the plan, leading him to beef up security in the building. Nonetheless, Franklin shoots his way through the guards at the site and catches up to Bonelli as he is taking off via helicopter from the roof. Franklin kills the last of his men and then shoots down the helicopter, causing it to crash and result in Bonelli's death.
After his death, the stock for Gold Coast receives a massive bump in share prices.
