Possession of Machine Gun While on Probation for Two Armed Robberies Nets Felon 57 Months in Prison

            WASHINGTON – Derkwon Johnson, 26, of the District of Columbia, was sentenced today in U.S. District Court to 57 months in prison in connection with being a felon in possession of a loaded Glock 23 equipped with a machine gun conversion device, while he was on probation for two armed robberies, an assault, and other crimes.  The sentence was announced by U.S. Attorney Jeanine Ferris Pirro.

            Johnson pleaded guilty on Jan. 29, 2025, to unlawful possession of a firearm and ammunition by a felon. In addition to the prison sentence, Judge Loren L. AliKhan ordered Johnson to serve three years of supervised release.

            According to court papers, in December 2023, MPD investigators were alerted to Johnson’s posts on Instagram depicting large clear plastic bags of a green leafy substance, a firearm, and ammunition. On Jan. 4, 2024, Officers with the Sixth District Crime Suppression Team executed a residential search warrant on Johnson’s home on the 3600 block of Minnesota Ave. SE.

            Officers entered Johnson’s apartment shortly after 6 a.m. to find six occupants – Johnson, Johnson’ half-sister, and her four small children – in a bed in a second bedroom. In the first bedroom, which was not occupied as police entered, officers recovered a .40 caliber Glock 23 pistol from the top of a piece of bedside furniture. The pistol, loaded with 28 rounds of ammunition, was equipped with a machine gun conversion device.

            Police also recovered a loaded ammunition magazine, a firearm laser attachment, addition ammunition, a bag containing 335 grams of a green leafy substance, a pill bottle containing 40 white pills stamped RP/10 325 (oxycodone), a scale, and $4,704 in cash.

            Investigators searched Johnson’s Instagram account and discovered multiple chats, videos, and messages advertising or arranging for the sale of pills and marijuana between Oct. 4, 2023, and Jan. 4, 2024.

            At the time of the January 4 arrest, Johnson was on probation for 2018 convictions in D.C. Superior Court for conspiracy to commit robbery, two counts of armed robbery, two counts of possession of a firearm during a crime of violence, possession with intent to distribute (PCP), and assault with a dangerous weapon.

            This case was investigated by the Metropolitan Police Department, the FBI Washington Field Office, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. It was prosecuted by Assistant U.S. Attorney Sarah Martin.
