Jevaughn Mark, a 33-year-old resident of Washington D.C., has pleaded guilty to charges related to the distribution of fentanyl and cocaine in the metropolitan area. His activities included selling fentanyl that led to the deaths of two men from Northwest D.C. in December 2023.
Mark, also known as "Ledo," entered his plea before U.S. District Court Judge Tanya S. Chutkan. He admitted to conspiracy for distributing 40 grams or more of fentanyl and 500 grams or more of cocaine, along with unlawful possession of a firearm by a felon. His sentencing is set for June 13, 2025.
The announcement was made by U.S. Attorney Edward R. Martin, Jr., DEA Special Agent in Charge Ibrar A. Mian from the Washington Division, and Chief Pamela A. Smith of the Metropolitan Police Department (MPD).
Mark faced eight counts related to unlawful distribution involving fentanyl, cocaine, and heroin between January 10, 2024, and March 13, 2024. The charges were based on six controlled purchases conducted by undercover DEA and MPD taskforce officers who contacted Mark seeking "Special K" or ketamine but received mixtures containing fentanyl instead.
Following an indictment, law enforcement searched Mark's residence where they found firearms, cocaine, fentanyl, approximately $38,000 in cash, body armor vests, and drug trafficking equipment.
On June 13, 2024, Mark was charged again with distributing substances on December 26, 2023—identified as causing the deaths of Brandon Román and Robert Barletta at their home in Northwest Washington. As part of his plea agreement, Mark confessed to selling what he claimed was "ketamine" but was actually fentanyl to one victim who then shared it with another victim; both were found unresponsive shortly after.
The case continues under investigation by the DEA’s Washington Division alongside the Metropolitan Police Department and is being prosecuted by Assistant U.S. Attorneys Iris McCranie and Dan Seidel from the Violence Reduction and Trafficking Offenses section.
