On the night of June 19, 2007, William Marquez Aull, a 20-year-old father from the 1600 block of Trinidad Avenue NE, was found in an alley behind 1211 18th Street NE after neighbors reported the sound of gunfire. Officers discovered Aull with gunshot wounds to the head and upper body; medics pronounced him dead at the scene. Detectives in the Metropolitan Police Department’s Violent Crimes Branch handled the investigation and circulated a reward flyer listing Detectives Edward Truesdale and Tony Paci and offering up to $25,000 for information leading to an arrest and conviction.

Police and court data compiled later classified the killing as a shooting with robbery suspected and the case status as open. Family and friends have kept his memory alive through obituary guestbook posts and remembrances.

Does anyone who lived in Trinidad that June night remember activity behind 1211 18th Street NE or have information that could help solve this case?
