In August 2008, Gotti was arrested and indicted on racketeering and murder conspiracy charges brought in Florida. The charges stemmed from an alleged drug trafficking ring Gotti operated along with former associate-turned-government witness John Alite, and with the murders of George Grosso in 1988, Louis DiBono in 1990 and Bruce John Gotterup in 1991. Prosecutors charge that the ring distributed at least five kilograms of cocaine in the late 1980s and early 1990s. Gotti's trial was later moved to New York, where he pleaded not guilty, and began in September 2009.
