Robert Aaron Long, 21, is the suspect in the three shootings. As confirmed to Complex by the Cherokee Sheriff’s Department, Long—who was arrested late Tuesday in Crisp County—took responsibility for the shootings in Cherokee County and Atlanta. On Wednesday, it was revealed—per the Atlanta Journal-Constitution—that Long informed investigators of his original plan to also drive to Florida to potentially carry out additional and similar acts of violence.

Earlier, APD said video footage from their video integration center placed the suspect’s vehicle in the Piedmont Road area around the time of those shootings. Additional video evidence also pointed to Long being responsible for all three shootings.

“I commend law enforcement for their quick work in arresting a suspect in the tragic shootings on yesterday,” Mayor Keisha Lance Bottoms said in a statement. “A motive is still not clear, but a crime against any community is a crime against us all. I have remained in close contact with the White House and APD as they work with federal, state and local partners to investigate the suspect who is responsible for this senseless violence in our city. My prayers are with the families and friends of the victims whose lives were cut short by these shootings.”

A 9mm handgun was found in Long’s car at the time of his arrest. On Wednesday, Long was taken to the Cherokee County Adult Detention Center. A rep for the Cherokee Sheriff’s Office told Complex he is currently charged with four counts of murder and one count of aggravated assault. He has no bond.
