WASHINGTON – Raymond Mathis, 36, of Washington, D.C., was presented in Superior Court today on charges of first degree felony murder while armed stemming from the homicide of 32-year-old Matthew Miller, on September 6, 2023, in the city’s Wharf neighborhood, U.S. Attorney Matthew M. Graves announced.
Mathis is the third defendant charged in the case. He was arraigned before Magistrate Judge Judith Pipe and entered a plea of not guilty. The court found probable cause to believe that the defendant committed first degree felony murder while armed. Mathis is being held without bond pending a September 27 preliminary hearing before Judge Anthony Epstein.
An arrest on a complaint is merely a formally charged allegation that a defendant has committed a violation of criminal laws and every defendant is presumed innocent until, and unless, proven guilty.
In announcing the charge, U.S. Attorney Graves commended the work of those investigating the case from the Metropolitan Police Department (MPD) and the U.S. Attorney’s Office. 
Making sure that victims of crimes are treated with compassion, fairness and respect.
