Alonzo Robinson Jr., 19, was shot and killed in Hagerstown, Maryland, on the evening of September 27, 2019. He had been at a cookout to celebrate his father’s birthday when an altercation involving Robinson, Ayaga McKell, and Juwan Campbell occurred. Later that evening the dispute continued at the intersection of Madison Avenue and West Washington Street, where Robinson was fatally shot.

Investigators charged Juwan Campbell in connection with Robinson’s death; a criminal information was filed January 15, 2020, and counsel entered for Campbell on January 17, 2020. The case went to trial November 15–19, 2021. Testimony at trial included accounts of the cookout altercation, electronic messages recovered from a mobile phone, and an officer’s testimony linking a phone number to Campbell through communications with Ayaga McKell and another person. An appeal was later filed raising issues from a May 25, 2021 hearing and trial rulings.

Does anyone have information about Robinson, the cookout that night, or events near Madison Avenue and West Washington Street on September 27, 2019?
