WASHINGTON – William Brock, 33, and Anthony Antwon McNair, Jr., 36, both of Washington, D.C., were sentenced today to 657 months (54.75 years) months and 378 months (31.5 years) in prison respectively for their roles in a series of armed robberies of Brink’s armored cars in Washington, D.C., that resulted in the loss of more than $1.2 million. 

           The sentences were announced by U.S. Attorney Edward R. Martin, Jr., FBI Special Agent in Charge Sean Ryan of the Washington Field Office’s Criminal and Cyber Division, and Chief Pamela Smith of the Metropolitan Police Department (MPD).

           Brock and McNair were found guilty by a federal jury on September 9, 2024, of conspiracy to interfere with interstate commerce by robbery, interference with interstate commerce by robbery (Hobbs Act Robbery), bank robbery, and brandishing a firearm during a crime of violence. The jury also found co-defendant Erin Sheffey guilty the same day of conspiracy to interfere with interstate commerce by robbery. Sheffey was sentenced January 15, 2025, to 18 years in prison.

           In addition to the prison terms, U.S. District Court Judge Royce Lamberth ordered Brock and McNair to each serve three years of supervised release and pay $1.2 million in restitution.

          The three Brink’s truck robberies occurred on October 6, 2021, December 8, 2021, and March 2, 2022. In those robberies, the defendants used firearms to assault the drivers of Brink’s armored cars and steal money. In total, the defendants stole over $1.2 million. 

            According to court documents and the evidence at trial, the three defendants were members of the Choppa City street crew. Brock, McNair, and Sheffey conspired together and with others to plan and carry out the robberies, brandishing firearms on busy District streets while doing so. 

           Each robbery occurred on a Wednesday at about 9 a.m., and two occurred on busy city throughfares, causing a significant risk to the public. Testimony in the case revealed that the conspirators used assault rifles to carry out their robberies. 

          Brock planned the robberies for months, learning the routes and arrival times of the Brink’s drivers, to ensure the robbery team was in place. As the Brink’s driver exited his armored car vehicle to deliver money to a business, the robbers ambushed him. In two cases, the defendants assaulted one of the Brink’s drivers, even after he had complied to their demands and had turned over his courier bag.

          Members of the crew used social media to show off large sums of money they stole during the robberies and photographed themselves making high-end luxury purchases. For example, within two days of the robberies, Brock purchased vehicles in cash totaling over $36,000. 

           Leading up to trial, all three men attempted to intimidate witnesses in the case. These attempts, among other things, were cited as bases for their decades-long sentences.

          This case was investigated by the FBI Washington Field Office’s Violent Crimes Task Force and the Metropolitan Police Department. It was prosecuted by Assistant U.S. Attorney Cameron Tepfer and Special Assistant U.S. Attorney Alex Schneider. Valuable assistance was provided by Assistant U.S. Attorneys Josh Gold, Meredith Mayer-Dempsey, and Thomas Strong.
