Norcross, GA (WXIA) -- Police believe four people shot and killed inside a local spa late Tuesday were targeted by the gunman, who later killed himself.
According to police, the victims were shot to death inside the Su Jung Beauty Health & Sauna . Norcross police responded to the business just before 9 p.m.
Surveillance video shows a man entering the spa, talking to an employee, and then opening fire. Four people inside were shot.
According to police, the gunman goes in and out of the frame of video during the shooting and apparently kills himself off camera.
Norcross Police Chief Warren Summers said they are investigating the relationships between the shooter and the victims, but they already know he was a frequent visitor to the spa.
About 20 people were inside the building at the time of the shooting, but not all of them were witnesses. Many of the workers and customers were in other parts of the 50,000-square-foot building.
The Georgia Bureau of Investigation assisted Norcross Police at the scene. Chief Summers said the interviews were complicated due to a language barrier.
Police are not releasing the names of the victims or the shooter pending notification of relatives.
