One person was killed and another injured in a shooting that occurred after a graduation ceremony in Clayton County, Ga., Friday night, the Associated Press reported. A third victim was not shot but was injured after being pushed, officials told 11Alive.

Shots were fired in the parking lot of Mount Zion High School off Mount Zion Road, south of Atlanta, after an argument between people leaving a commencement ceremony for the Perry Learning Center, an alternative-learning high school, Clayton County Schools Safety Chief Thomas Trawick told the Associated Press. The ceremony was held Friday evening across the street from the high school, at the school’s performing arts center.

“The last thing you want to do is have a situation at a graduation that results in anyone being injured and definitely not being shot,” Trawick told 11Alive.

A police statement said “one person is now confirmed deceased,” the Associated Press reported.

Clayton County Fire Department officials told 11Alive that the woman who died was in her 40s and was shot three times in the chest. She was taken to Southern Regional Medical Center, where she was later pronounced dead.

A 21-year-old victim suffered gunshot wounds to the leg and was taken to Atlanta Medical Center. A pregnant woman was taken to Piedmont Henry Hospital, officials told 11Alive.

The shooting happened on the same day as a mass shooting at Santa Fe High School in Southeast Texas that left at least 10 people, mostly students, dead.
