Titus Jackson, 26, was found fatally shot on Clay Street in Northeast Washington, D.C., on the evening of September 11, 2014. Police responded to reports of gunfire at about 6:10 p.m.; Jackson was pronounced dead at the scene and the Metropolitan Police Department’s Homicide Branch opened an investigation.

Detectives identified a suspect and on November 21, 2014, arrested 25-year-old Vernon Hedrick of Northeast D.C., charging him with first-degree murder. Investigators said surveillance footage from 6:09 p.m. on the day of the shooting showed Hedrick walking with Jackson and a third unidentified person in the same block where the shooting occurred. A judge found probable cause to hold Hedrick in December 2014, and the case later went to trial.

Does anyone have information about Titus Jackson, the people he was with that evening, or the third person seen on the surveillance footage?
