Long Island Man Indicted for Causing Overdose Death in Suffolk County

Marlon Thompson was arraigned this afternoon 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 December 26, 2018.  Thompson was ordered detained pending trial.

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

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

“Marlon Thompson showed no regard for human life when he allegedly sold a lethal dose of fentanyl to the victim,” stated 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.”  Mr. 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.”

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.
