Member of Fitchburg Latin Kings Chapter Pleads Guilty Drug Distribution Charges

For Immediate Release
U.S. Attorney's Office, District of Massachusetts

BOSTON – A member of the Fitchburg Chapter of the Massachusetts Almighty Latin King and Queen Nation (“Latin Kings”) pleaded guilty today to drug distribution charges.

Dairon Rivera, a/k/a “King Mafia,” 27, pleaded guilty today to one count of conspiracy to distribute and possess with intent to distribute fentanyl. U.S. Senior District Court Judge Rya W. Zobel scheduled sentencing for April 1, 2021. Dairon Rivera was charged in December 2019, at which time he was a member of the Fitchburg Chapter of the Latin Kings.

The Latin Kings are a violent criminal enterprise comprised of thousands of members across the United States. As alleged in court documents, the gang uses drug distribution to generate revenue, and engages in violence against witnesses and rival gangs to further its influence and to protect its turf.

During the plea proceedings, Dairon Rivera admitted to selling over 40 grams of fentanyl to a cooperating witness in a series of audio/video recorded sales that took place between April and December of 2017. 

In December 2019, a federal grand jury returned an indictment alleging racketeering conspiracy, drug conspiracy and firearms charges against 62 leaders, members and associates of the Latin Kings. Dairon Rivera is the 26th defendant to plead guilty in the case.

The charge of conspiracy to distribute controlled substances provides for a sentence of up to 20 years in prison, a minimum of three years and up to life of supervised release and a fine of up to $1 million. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors.

United States Attorney Andrew E. Lelling; Joseph R. Bonavolonta, Special Agent in Charge of the Federal Bureau of Investigation, Boston Field Division; and Commissioner Carol Mici of the Massachusetts Department of Correction made the announcement today. Valuable assistance was also provided by the FBI North Shore Gang Task Force and the Bristol County and Suffolk County District Attorney’s Offices. Assistant U.S. Attorneys Philip A. Mallard and Lauren Graber of Lelling’s Criminal Division are prosecuting the case.

The details contained in the charging documents are allegations. The remaining defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.

This case is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation. OCDETF identifies, disrupts, and dismantles the highest-level criminal organizations that threaten the United States using a prosecutor-led, intelligence-driven, multi-agency approach.
