D.C. Felon Sentenced for Possession of a P90 ‘Ghost Gun’

WASHINGTON - Dayvon Darius Marson, 31, a previously convicted felon residing in the District, was sentenced today in U.S. District Court to 24 months in federal prison in connection with his possession of a loaded pistol -- an unbranded, non-descript P90 ghost gun -- and attempting to flee from a police traffic stop with it at a crowded gas station, announced U.S. Attorney Jeanine Ferris Pirro.

Marson pleaded guilty on April 30, 2026, before Chief Judge James E. Boasberg to a charge of unlawful possession of a firearm by a felon. In addition to the 24-month prison term, Chief Judge Boasberg ordered Marson to serve 3 years of supervised release. Federal prosecutors had requested a 24-month prison sentence.

According to court documents, on Feb. 26, 2026, about 6:15 p.m., Metropolitan Police Department officers were patrolling the 3800 block of Minnesota Avenue NE, with members of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Homeland Security Investigations (HSI), and the FBI.

While patrolling, members noticed a Toyota Avalon sedan with heavily tinted windows at the Citgo gas station. Marson was in the driver's seat and a young child in the rear-passenger seat. Officers questioned Marson, who could not provide a driver's license. Speaking with Marson, an MPD officer spotted a half-empty bottle of tequila on the floor behind the driver's seat.

The MPD officer ordered Marson to step out of the vehicle. Marson refused to do so. An ATF special agent opened the driver's door and also ordered Marson to step out of the vehicle. Marson again refused to comply. Marson then put the transmission in "drive" and stepped on the accelerator, causing the vehicle to jolt forward as the ATF agent held onto the door. The vehicle dragged the ATF agent several feet before it collided with another parked vehicle.

After a brief struggle, members restrained Marson. As they did so, members spotted a brown P90 handgun with no serial number laying on the driver's seat on which Marson had been sitting. The firearm was loaded with one round of .40 caliber ammunition in the chamber and 12 rounds in the magazine. During a search of Marson members recovered 11 multi-colored pills in a clear plastic bag from his socks. The pills were field-tested and yielded a positive indication for amphetamines.

This case was investigated by the Metropolitan Police Department, the Bureau of Alcohol, Tobacco, Firearms and Explosives, Homeland Security Investigations (HSI), and the FBI Washington Field Office.

The matter was prosecuted under the Make D.C. Safe and Beautiful initiative by Assistant U.S. Attorney Mark Levy.  

Make D.C. Safe and Beautiful supports President Trump's Executive Order that cracks down on gun violence, prioritizes federal firearms violations, pursues tougher penalties, and seeks detention for federal firearms violators.
