Two people were arrested after a fatal shooting in the parking lot of a Clayton County high school late Friday.

The shooting occurred around 8 p.m. in the parking lot of Mt. Zion High School in Jonesboro. It happened after the graduation of Perry Career Academy, which was held at a nearby Performing Arts Center, according to a spokesperson with Clayton County Schools.

Police say the shooting occurred after an argument.

A woman was killed after being shot three times in the chest, according to Clayton County Fire and Emergency Services. Her identity was not immediately released.

Another woman, 21, was shot in the leg and taken to the hospital. Her identity is also unknown.

"All of the sudden, we all heard a series of gunshots," said witness Shannon Delgado. "We didn't know where they were coming from. Everybody just kind of froze, then we didn’t hear police, we heard more gunshots, but like a lot, like, 'Pow, pow, pow, pow.' That's when we saw the cops, who were on the premises where the graduation was rush across the street because they were in the high school parking lot."

Clayton County police confirmed to CBS46 that two people were arrested in connection with the incident. Police say their names and charges are not being released yet, as additional charges are pending.
