Antonio McCallister was 23 when he was shot and killed in Southeast Washington, D.C., on Friday, July 24, 2015. The shooting happened about 10:30 p.m. in the 2700 block of Langston Place SE in the Woodland Terrace neighborhood. McCallister was with friends when a gunman approached from behind and shot him; he was taken to a hospital and died of his wounds.

Police identified a neighbor, 23-year-old Eric McDuffie, as the alleged assailant and charged him with first-degree murder while armed. The case went to trial; an April 2018 trial ended in a hung jury. At a second trial, prosecutors presented eyewitness testimony, including McCallister’s mother, who said she saw McDuffie behind her son when the shooting occurred. The defense questioned witness credibility and said police had not fully investigated another potential suspect reportedly identified by a neighborhood boy soon after the shooting.

In December 2018 a jury acquitted McDuffie, leaving McCallister’s killer officially unidentified. Does anyone in Woodland Terrace remember that night or have information that could help close this case?
