On the morning of August 20, 2014, a daylight shooting in New Kensington, Pennsylvania, killed 43-year-old John T. Russ III and his girlfriend, Shannon Bongartz. Russ was found inside his car and Bongartz was found in the street nearby; both had sustained multiple gunshot wounds. Russ was a father of two sons, a lifelong area resident and a self-employed handyman.

Investigators quickly tied the killings to a dispute over a drug debt and said witnesses reported seeing a man dressed in black fleeing the scene. Police identified 18-year-old Brian Hall of Penn Hills as the prime suspect. The next day Hall was found shot and killed in the Homewood section of Pittsburgh, and authorities publicly named him as responsible for the deaths of Russ and Bongartz.

Who in the community might have information about the dispute or the man seen running from Fourth Avenue that morning?
