Jayla Brown, a 19-year-old woman from Pittsburgh, was killed on August 9, 2007, when at least two gunmen fired more than 20 rounds into a car in the Lawrenceville neighborhood. She had been celebrating her birthday and was on a first date that evening; she and her date, 22-year-old James Johnson, had gone to a movie, dinner, and later to a recording studio on Butler Street. Jayla was struck and killed in the vehicle; Johnson was wounded.

Police early on treated Johnson as the intended target and Jayla as an unintended victim. Investigators say Johnson initially gave a false name, was later identified, and had an outstanding warrant for drug and firearms violations. The shooters were described as men in hooded sweatshirts who fled in a dark green and gold Chevrolet Astro van. No arrests have been announced and no suspects have been publicly identified.

Who in Lawrenceville that night might have seen the van, the shooters, or anyone following the car?
