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 IRVIN CARTAGENA, a/k/a “Green Eyes,” pled guilty today to conspiring to distribute heroin, fentanyl, and fentanyl analogue.  As part of the conspiracy, CARTAGENA distributed the fentanyl-laced heroin that resulted in the death of Michael K. Williams.  CARTAGENA pled guilty earlier today before U.S. District Judge Ronnie Abrams.

U.S. Attorney Damian Williams said: “Irvin Cartagena sold fentanyl-laced heroin in broad daylight in New York City, feeding addiction and causing tragedy.  In doing so, he dealt the fatal dose that killed Michael K. Williams.  This Office and our law enforcement partners will continue to hold accountable the dealers who push this poison, exploit addiction, and cause senseless death in our community.”

According to the allegations in the complaints, court filings, and statements made in Court:

Between at least in or about August 2020 and February 2022, a drug trafficking organization (the “DTO”) was operating in the vicinity of 224 South 3rd Street in the Williamsburg neighborhood of Brooklyn, New York.  The DTO sold heroin laced with fentanyl and a fentanyl analogue on the street in front of, and from an apartment inside of, the apartment building located at 224 South 3rd Street, among other places.  On or about September 5, 2021, members of the DTO sold Michael K. Williams heroin, which was laced with fentanyl and a fentanyl analogue, with CARTAGENA executing the hand-to-hand transaction.  Williams died as a result of using that fentanyl-laced heroin.  Despite knowing that Williams died after being sold the DTO’s product, CARTAGENA and his co-conspirators continued to sell fentanyl-laced heroin in broad daylight amidst residential apartment buildings in Brooklyn and Manhattan.

CARTAGENA, 39, of Brooklyn, New York, pled guilty to one count of conspiracy to distribute and possess with intent to distribute fentanyl analogue, fentanyl, and heroin, which carries a mandatory minimum sentence of five years in prison and a maximum sentence of 40 years in prison.  As part of his guilty plea, CARTAGENA stipulated that the substances he conspired to distribute and possess with intent to distribute resulted in the death of Michael K. Williams.

The statutory minimum and maximum penalties are prescribed by Congress and are provided here for informational purposes only, as any sentencing of the defendant will be determined by the judge.

Mr. Williams praised the outstanding work of the New York City Police Department and the New York/New Jersey High Intensity Drug Trafficking Area Intelligence Analysts.  Mr. Williams also thanked the Organized Crime Drug Enforcement Task Forces New York Strike Force, the United States Marshals Service, the New York/New Jersey Regional Fugitive Task Force, and the New York Division of the Drug Enforcement Administration for their assistance in this case. 

This case is being handled by the Office’s Narcotics Unit.  Assistant U.S. Attorneys Micah Fergenson and David Robles are in charge of the prosecution.
