WASHINGTON – Mark Thomas Moore, 35, of the District of Columbia, was sentenced today in U.S. District Court to 180 months in prison in connection with a string of armed robberies that targeted service workers at businesses and a U.S. Post Office in the District, announced U.S. Attorney Jeanine Ferris Pirro.
“Mark Moore targeted hardworking employees who were simply doing their jobs. He threatened them at gunpoint, leaving many with lasting trauma,” said U.S. Attorney Pirro. “Today’s sentence ensures that Moore will be held accountable for his actions and will not be able to harm anyone in our community for a long time.”
Moore was convicted Nov. 6, 2025, following a bench trial before Judge Amit P. Mehta, of two counts of interference with commerce by robbery (Hobbs Act), of one count of armed robbery while armed, of one count of possession of a firearm during a crime of violence, and of one count of armed postal robbery.
In addition to the 180-month prison sentence, Judge Mehta ordered Moore to serve five years of supervised release. Federal prosecutors had requested a prison term of 180 months.
According to court papers, in the fall of 2022, Moore armed himself with a BB gun to rob service workers at business in the District and Arlington, Virginia.
On Oct. 26, 2022, Moore entered a McDonald’s restaurant on the 1500 block of Pennsylvania Avenue SE, where he lurked for about 15 minutes before following a female employee into a restroom. There, he held the worker at gunpoint. The employee had recently immigrated into the U.S. and spoke no English. She attempted to use a translation app on her phone to communicate with Moore. Moore took her phone and forced her through the restaurant to the cash register where he ordered another employee to fill a bag with money before fleeing.
On Nov. 9, 2022, Moore entered a 7-Eleven on the 1500 block of Independence Ave. SE. He pointed his BB gun at an employee and demanded cash.
When the employee attempted to conceal some of the money, Moore threatened him with the gun.
On Nov. 28, 2022, Moore was armed when he entered the U.S. Postal Service facility on the 600 block of Pennsylvania Ave., SE. As employees fled in fear, Moore stood over one who had fallen while trying to escape. He pointed the weapon at her threatened her as she pleaded for her life. He then forced a third employee to the register at gunpoint before fleeing the post office on a distinctive green bicycle.
On Nov. 28, 2022, Moore also robbed a CVS in Arlington, Virginia. During the robbery, Moore took a bank note containing a GPS tracker. He fled on the same distinctive green bicycle. Law enforcement later located Moore and recovered a BB gun consistent with the weapon seen in the surveillance footage from the three District robberies. Investigators also recovered clothes recovered from his girlfriend’s apartment, along with DNA and fingerprints, that further linked him to the offenses.
This investigation was conducted by the FBI Washington Field Office, the Metropolitan Police Department and the Arlington County Police Department. The matter was prosecuted by Assistant U.S. Attorneys Caelainn Carney and Jared English.
