Jon Newman, 45, was found dead on June 7, 2017, in Fort Lauderdale, Florida, the victim of a violent altercation that resulted in a fatal gunshot wound. His body was discovered in the early morning by a passerby who alerted authorities, and police treated the case as a homicide from the start.

Witnesses reported raised voices and a gunshot but did not see the shooting itself. Investigators recovered surveillance footage showing a shadowy figure fleeing the scene, but the video quality prevented a positive identification. Police identified several persons of interest and followed leads, but the investigation eventually went cold for lack of new information.

What did anyone in the Fort Lauderdale area see or hear that might help identify the person who fled that night?
