Marlon Thompson, Drug Trafficking and Firearms Offenses, New York 2024

A federal jury in Central Islip, New York, convicted Marlon Thompson, 41, of Selden, on all four counts of an indictment charging him with conspiracy to distribute fentanyl, heroin, and cocaine base, the distribution of fentanyl that caused the death of 36-year-old Fredrick Koenig on Christmas Day 2018, and illegal possession of firearms.

The verdict followed a six-day trial before United States District Judge Joan M. Azrack. Thompson faces a mandatory minimum sentence of 20 years’ imprisonment and up to life in prison.

Breon Peace, United States Attorney for the Eastern District of New York, Frank A. Tarentino, Special Agent-in-Charge, Drug Enforcement Administration (DEA); and Rodney J. Harrison, Commissioner, Suffolk County Police Commissioner (SCPD), and Raymond A. Tierney, Suffolk County District Attorney, announced the verdict.

“Today, the defendant was held accountable for trafficking fentanyl that caused the tragic overdose death of a young man on Long Island,” stated United States Attorney Peace. “The large quantities of fentanyl the defendant distributed all over Suffolk County had a devastating impact on the community, including by taking this young man away from his family too soon. This Office, together with our federal and local partners, will continue to work tirelessly to prosecute those who contribute to this serious problem.”

The evidence proved that, from January 2017 through May 2019, the defendant conspired to distribute fentanyl, heroin, and cocaine base throughout Suffolk County. On Christmas Day in 2018, the defendant supplied fentanyl to the victim, who suffered a fatal overdose at his parents’ home in Selden, New York. The defendant continued supplying fentanyl, heroin, and crack in Suffolk County for months after Koenig’s death.

When sentenced, Thompson will face a mandatory minimum sentence of 20 years’ imprisonment and up to life in prison. The government’s case is being handled by the Office’s Long Island Criminal Division. Assistant United States Attorneys Samantha Alessi, Gabriel Park, and Catherine M. Mirabile are in charge of the prosecution with assistance from Paralegal Specialist Adam Bernard.
