The two slain victims of Tuesday’s mass shooting at a Virginia high school graduation ceremony have been identified as an 18-year-old senior and his father who was killed just minutes after watching his son graduate.

A family member named the father and son as 36-year-old Renzo Smith and Shawn Jackson.

Gunfire erupted around 5:15 p.m. Tuesday outside Altria Theater in downtown Richmond, Virginia, as a crowd of graduates and their families were filing out of the venue.

Police said seven people were struck with bullets, leaving two dead and five wounded. At least 12 others were hurt in the chaos, or required treatment for anxiety.

Jackson’s 9-year-old sister was reportedly hit by a car in the mayhem triggered by the shooting.

A 19-year-old suspect tried to flee on foot but was arrested and will be charged with two counts of second-degree murder.

Police believe the accused gunman, who was not immediately identified, knew at least one of the victims.

“This should have been a safe space. People should have felt safe at a graduation,” Richmond Acting Police Chief Rick Edwards said. “It’s just incredibly tragic that someone decided to bring a gun to this incident and rain terror on our community.”
