New York Gang Member Sentenced To 25 Years In Prison For 2010 East Harlem Murder

For Immediate Release
U.S. Attorney's Office, Southern District of New York

Damian Williams, the United States Attorney for the Southern District of New York, announced that JAMAL ADAMSON, a/k/a “J-Rock,” was sentenced today to 25 years in prison for the June 20, 2010, murder of David Moore in East Harlem and other racketeering offenses.  ADAMSON previously pled guilty before United States District Judge Gregory H. Woods, who imposed the sentence.   

U.S. Attorney Damian Williams said: “Jamal Adamson callously took the life of another during a gang-related shooting.  As today’s sentence shows, those who commit acts of gang violence in New York City are subject to spending serious time in federal prison.”

As alleged in the Indictment and other documents filed in federal court and based on statements made in public court proceedings:

The Cash Money Boys (“CMB”) gang was a criminal enterprise involved in committing numerous acts of violence, including murder, attempted murder, robberies, and assaults, in and around Manhattan.  Members and associates of CMB engaged in violence to retaliate against rival gangs, to promote the standing and reputation of CMB, and to protect the gang’s narcotics sales. 

From at least in or about 2006 to in or about 2017, members and associates of CMB regularly distributed crack cocaine and other drugs in the vicinity of Lexington Avenue between East 122nd Street and East 123rd Street.  CMB controlled drug sales within this area by preventing non-members, outsiders, and rival drug dealers from selling drugs in the area controlled by the gang.  This included gang members shooting at, assaulting, and/or robbing other drug dealers and members of rival gangs who entered CMB’s territory.  

On June 20, 2010, after members of CMB and a rival gang got into a physical altercation, ADAMSON shot and killed David Moore, 23, near the corner of East 122nd Street and Lexington Avenue.

In addition to his prison sentence, ADAMSON, 28, of New York, New York, was sentenced to three years of supervised release.    

Mr. Williams praised the outstanding work of the Special Agents of the United States Attorney’s Office for the Southern District of New York and the New York City Police Department.   

The case is being prosecuted by the Office’s Violent and Organized Crime Unit.  Assistant U.S. Attorneys Maurene Comey, Dominic A. Gentile, Christopher J. Clore, and Peter J. Davis are in charge of the prosecution.
