On Monday afternoon, March 29, 2021, 21-year-old Dominic Billa was shot and killed in the food court of the Philadelphia Mills mall after a dispute turned into a physical altercation. Witnesses and surveillance footage show the fight escalated when 23-year-old Gregory Smith produced a handgun and fired; Billa was struck twice in the chest and pronounced dead at the scene. The mall locked down as shoppers fled.

Investigators say Smith and another man confronted Billa over an ongoing dispute, then fled on a SEPTA bus and went to a hotel in South Jersey. Billa was the stepson of a Philadelphia homicide detective. Surveillance footage helped identify a suspect, and within a month authorities arrested Smith and charged him with murder and related offenses.

Does anyone have information about Dominic’s activities at the mall that afternoon or recall seeing the men involved before the shooting?
