Federal prosecutors have charged a man who allegedly sold a firearm to the person responsible for the Old Dominion University shooting, even though the shooter had been previously convicted in a terrorism case. The charges were announced Friday by the Justice Department. The case highlights serious concerns about how someone with a terrorism conviction was able to obtain a weapon. Federal law prohibits people with certain criminal backgrounds, including terrorism convictions, from purchasing or possessing firearms. While Old Dominion University is located in Norfolk, Virginia, the federal charges underscore the broader regional impact of gun violence and the ongoing efforts to hold accountable those who illegally provide weapons to prohibited buyers. The investigation appears to be part of federal authorities' continued focus on tracking how firearms end up in the hands of people who shouldn't have them. Details about the specific charges and the timeline of events have not yet been fully released, but the case represents another step in the legal proceedings following the university shooting incident.
