Aaron Justin Wornum, a 25-year-old Black man, was fatally shot in Dorchester on the evening of June 26, 2011. The shooting happened around 9 p.m. near the corner of Sumner and East Cottage streets. Wornum was taken to Boston Medical Center, where he died of his wounds.

Boston Police identified a suspect and arrested 20-year-old Anthony Robertson of Dorchester in July 2011. Prosecutors said Robertson had been on the phone with Wornum just before the shooting and that Wornum was shot multiple times after an argument. Robertson was charged with murder and unlawful possession of a firearm, arraigned in Dorchester District Court, and held without bail.

Robertson was convicted of first-degree murder in Wornum’s death, but the conviction was later overturned by the Supreme Judicial Court on grounds related to how the trial judge handled the prosecution’s dismissal of two men of color from the jury pool, and the court ordered a new trial. Does anyone have information about Wornum’s life, his activities in Dorchester that night, or witnesses who saw the shooting?
