Prosecutors in Washington, D.C., file new charges against a man accused of shooting National Guard members last year, a step that could expose him to the death penalty if convicted. CBS News reports that the Justice Department brings additional charges following the alleged fatal shooting of one National Guard member and the gravely injuring of another. The new filing is described as a superseding indictment, according to the New York Post. Both accounts say the conduct centers on an incident in Washington, D.C., involving the National Guard. The superseding indictment could allow federal prosecutors to seek capital punishment, depending on the outcome at trial and the applicability of the death-penalty statutes. The sources also indicate the case is active and moves through the court process, with the defendant appearing in court following the new charges. The reports do not describe details of a conviction or trial outcome, focusing instead on the procedural development and the potential penalties faced by the accused.
