United States Drug Enforcement Administration

BROOKLYN, N.Y. – Marlon Thompson was arraigned yesterday in federal court in Central Islip before United States Magistrate Judge A. Kathleen Tomlinson on an indictment charging him with conspiracy to distribute cocaine base and heroin from April 2018 through May 2019, and distribution of a controlled substance containing fentanyl resulting in the fatal overdose of a Fredrick Koenig of Selden, New York, on Dec. 26, 2018. Thompson was ordered detained pending trial.

Thompson was previously detained on state charges and was transferred into federal custody today.

United States Attorney for the Eastern District of New York Richard P. Donoghue and Drug Enforcement Administration New York Division Special Agent in Charge Ray Donovan announced the charges.

“Marlon Thompson showed no regard for human life when he allegedly sold a lethal dose of fentanyl to the victim,” said United States Attorney Donoghue. “This Office will continue to work tirelessly with our law enforcement partners to prosecute those who contribute to the opioid epidemic.” U.S. Attorney Donoghue thanked the Suffolk County District Attorney’s Office and the Suffolk County Police Department for their assistance on the case.

“Drug trafficking trends indicate that poly-drug doses are being sold on the street without customers’ knowledge of its potency,” said DEA Special Agent in Charge Donovan. “Case in point, a toxic cocktail containing fentanyl resulted in a fatal overdose. I applaud our law enforcement partners on their diligent work throughout this investigation.” SAC Donovan commends the Eastern District of New York and the Long Island District Office for their diligent efforts throughout this investigation. 

If convicted of distributing a controlled substance causing the death of Koenig, the defendant faces a mandatory minimum term of 20 years’ imprisonment and up to a maximum of life in prison.

The charges in the indictment are allegations, and the defendant is presumed innocent unless and until proven guilty. The government’s investigation is continuing.

The government’s case is being handled by the Office’s Long Island Criminal Division. Assistant United States Attorney Catherine M. Mirabile is in charge of the prosecution.
