On the night of June 24, 2026, 19-year-old Oscar Ruiz Mejia Jr. was found fatally shot in the 200 block of Ivanhoe Court in Fredericksburg, Virginia. Calls to the Fredericksburg E-911 Center came in just after 11 p.m.; officers arriving at the scene discovered Mejia with multiple gunshot wounds and he was pronounced dead there. Witnesses reported an argument between Mejia and another person immediately before the shooting.

Police say they located a man nearby who matched witness descriptions and recovered two firearms. That individual, 24-year-old Emmanuel Trevor Villamont Killeen of Fredericksburg, was initially arrested on concealed-weapons charges and identified as a person of interest. On June 29, investigators filed first-degree murder and a firearm felony charge in connection with Mejia’s death, and Killeen remained held without bond while the investigation continued.

Who in Fredericksburg might have seen activity on Ivanhoe Court that night or knows more about the argument before the shooting?
