Investigators ruled the crash an accident but Mr Favara was subjected to death threats and harassment for months, including having "murderer" spray-painted across his car.  The Gottis were crushed by their son's death. Victoria Gotti, the boy's mother, would reportedly walk out to the local baseball fields late at night in the hope she would find her son alive.  When Mr Favara tried to apologise to her, she attacked him with a baseball bat. He ignored advice to move away only to disappear after leaving work one day.  The Gottis proved to police they were in Florida at the time and no arrests were ever made. The police were reportedly later told that Gotti dismembered Mr Favara himself with a chainsaw when he returned from Florida.  Investigators now believe Mr Favara was forced into a van and shot in the legs before being taken to Brooklyn. There, they believe, he was killed and later pushed into a 55-gallon, cement-bottomed oil drum which was then dumped into the sea.  Gotti, who was only a captain in the Gambino family at the time, has provided New York with one of the city's most lurid Mafia careers.  Flamboyant and outspoken in public but brutal and quick-tempered in private, he reportedly beat his wife and elder son regularly.  During the late 1980s he was rumoured to be earning $1 million a month from organised crime as head of New York's biggest Mafia family.  He was dubbed the Teflon Don after twice being acquitted in court but, in 1992, he was convicted of 13 murders and numerous other charges. He died of throat cancer in prison 10 years later.  Carneglia, 62, has denied racketeering and five murder charges. Prosecutors claim he was part of a seven-strong hit squad that got rid of the Gambino clan's enemies.
A neighbour who accidentally ran over and killed the young son of the Mafia   boss John Gotti was shot dead and his body dissolved in a barrel of acid,   court papers have revealed.
