Eight people were killed and another person was wounded in a shooting spree Tuesday targeting massage parlors in the Atlanta area.

The shooting first began at Youngs Asian Massage in Acworth, a northwest suburb of Atlanta. Four people were killed in that attack, which took place at roughly 5 p.m., according to the Cherokee County Sheriffs Office.

Atlanta police later responded at 5:47 p.m. to a robbery at a massage parlor in the northeastern part of the city, where three women were found dead. Upon arriving at the scene, police received word of shots being fired at a spa across the street, where authorities found another woman dead.

Jay Baker of the Cherokee County Sheriffs Office confirmed in an email to several media outlets that Robert Aaron Long was arrested in Crisp County later Tuesday. Authorities had released images of Long outside one of the massage parlors asking the public for help identifying him.

Baker said Long is suspected of being behind all three shootings, but Atlanta police said it was still investigating whether the shootings were connected.

Many have asked whether these shootings are related to Cherokee Countys shootings, John Chafee, an Atlanta Police Department spokesman, said in an email to The Hill Tuesday night. At the moment, it is too early to confirm that, but we have spoken with Cherokee County officials and we are looking into that possibility.
