On the evening of May 11, 2015, 26-year-old Jamel Brown was fatally shot near Prospect Park in Brooklyn. The shooting happened in the early evening, when the park and nearby streets were busy, and also left a woman injured; she was taken to a nearby hospital for treatment. NYPD officers found Brown with a gunshot wound and emergency responders pronounced him dead at the scene.

The NYPD opened an investigation, canvassed the area for witnesses and evidence, and had not released details about a suspect, motive, or any arrests in the initial reports. The killing was one of several shootings in Brooklyn during that period, feeding concern about rising gun violence in the borough.

Did anyone in the Prospect Park area that evening see or hear anything that could help investigators?
