He was a "Gangsta Cop" according to federal prosecutors.
Vancito Gumbs, a so-called police officer in DeKalb County outside Atlanta, GA, is among four dozen low lives charged in a federal indictment for their alleged roles with Gangster Disciples as reported by the Chicago Tribune: "prosecutors say [Gumbs] claimed to be a hit man for the violent gang and tipped off other members about police activity."
Of course, the most notorious crooked cops with ties to organized crime have been with the historically corrupt NYPD.
Just last year Big Apple taxpayers shelled out $8.4 million to settle wrongful death actions for five notorious gangsters who were whacked by NYPD Mafia Cops Louis Eppolito and Stephen Caracappa as reported by John Marzulli for the Daily News: "the city agreed to pay $1.85 million to the estate of Lucchese soldier Anthony DiLapi; $1.8 million to Lucchese associate John (Otto) Heidel; $1.75 million to painter's union head and informant James Bishop; $1.5 million each to Gambino capo Edward Lino and soldier Bartholomew (Bobby) Borriello."
Eppolito and Caracappa were convicted in 2006 for multiple murders, and last year Brooklyn federal judge Raymond J. Dearie ruled that wrongful death lawsuits against the city by the victims' survivors may go to trial because "there was evidence to suggest the rubouts would not have occurred had Eppolito been kicked off the force or disciplined after he was 'caught red-handed' passing confidential police records to a mobster in 1984" as reported by Frank Donnelly for the Staten Island Advance.
