Preston D. Walker was shot and killed on October 3, 2006, at about 3:47 p.m. in front of a residence at 1925 M Street Northeast in Washington, D.C. He was the son of Carolyn Walker Webb and Shirley Webb and was survived by two sisters and three brothers.

The shooting happened in daylight and remains largely unexplained. The Metropolitan Police Department responded, but investigators have reported a lack of substantial evidence and witnesses. Flyers were later distributed and authorities have repeatedly asked the public for help, but no arrests have been announced and the case remains unsolved.

Does anyone have information about that afternoon or recall seeing anything near 1925 M Street Northeast on October 3, 2006?
