William Brock and Anthony Antwon McNair, Jr., both from Washington, D.C., have been sentenced to lengthy prison terms for their involvement in a series of armed robberies targeting Brink’s armored cars. The sentences were announced by U.S. Attorney Edward R. Martin, Jr., FBI Special Agent in Charge Sean Ryan, and Chief Pamela Smith of the Metropolitan Police Department.
Brock received a sentence of 657 months (54.75 years), while McNair was sentenced to 378 months (31.5 years) for their roles in the crimes that resulted in over $1.2 million being stolen. A federal jury found them guilty on September 9, 2024, of conspiracy to interfere with interstate commerce by robbery, interference with interstate commerce by robbery under the Hobbs Act, bank robbery, and brandishing a firearm during a crime of violence.
Co-defendant Erin Sheffey was also found guilty of conspiracy to interfere with interstate commerce by robbery and received an 18-year prison sentence on January 15, 2025.
In addition to their prison sentences, Judge Royce Lamberth ordered Brock and McNair to serve three years of supervised release and pay restitution totaling $1.2 million.
The robberies took place on October 6, 2021; December 8, 2021; and March 2, 2022. During these incidents, the defendants used firearms to assault Brink’s drivers and steal money. Court documents revealed that they were members of the Choppa City street crew and had conspired together to plan these heists using firearms on busy streets.
Each robbery occurred around 9 a.m., often on busy city thoroughfares posing risks to public safety. Testimonies indicated that assault rifles were used during these operations.
Brock meticulously planned these robberies by studying the routes and timings of Brink’s drivers. As drivers exited their vehicles for deliveries, they were ambushed by the robbers who sometimes assaulted them even after compliance.
Following the robberies, crew members flaunted their stolen wealth through social media posts showing off large sums of money and luxury purchases made shortly after the heists.
Attempts by all three men to intimidate witnesses before trial contributed to their severe sentencing decisions.
The case was investigated by the FBI's Violent Crimes Task Force alongside the Metropolitan Police Department and prosecuted by Assistant U.S. Attorney Cameron Tepfer along with Special Assistant U.S. Attorney Alex Schneider with support from other assistant attorneys.
