CAMDEN, N.J. (AP) — Federal prosecutors say a leader of a large-scale drug trafficking organization in southern New Jersey has been sentenced to 20 years in prison.

Jeffrey “Jazzy” Jones of Camden will also have to serve 12 years of supervised release once he’s freed from prison. And during that time, the 36-year-old Jones will not be allowed to live in or enter Camden, Gloucester, Burlington counties or Philadelphia without prior permission from his probation officer.

Jones had pleaded guilty to a complaint charging him with conspiracy to distribute 280 grams or more of crack cocaine. He was sentenced on Wednesday.

Prosecutors say Jones was a leader for a trafficking organization known as “The Firm,” which distributed about $4 million worth of cocaine from several locations in Camden from 1990 to 2007.
