A woman is in the hospital after she was shot while sitting in the back seat of her friend’s car on the Downtown Connector early Sunday.

Detectives met with the woman at Piedmont Hospital just before 2 a.m., Atlanta police said in a statement. The woman said she was sitting in the back seat when an “unknown vehicle” flashed its lights several times.

Then, the car approached the side of their vehicle and fired a single shot, police said.

Investigators said the suspect’s vehicle is a Black Lexus SUV. No other details about the vehicle or gunman was available.

Police are still trying to determine the circumstances that led to the shooting. The incident was one of three shootings Atlanta police were called to Sunday morning — and the second within five minutes, officials said.

Officers were sent to the 100 block of Williams Street at 1:53 a.m. after a man said he had been shot. The victim told police he was walking from his car when a group of men approached him. The men started an argument with the victim, and the dispute escalated into a shooting, police said. The victim was taken to Grady Memorial Hospital, where he is stable. No suspects have been identified.

Officers were sent to the 3200 block of Cushman Circle after a woman was shot in the leg about 6 a.m. She said she was walking across the road when a Black Chevrolet drove by and nearly hit her. Then, the car’s driver pulled out a gun and fired in her direction. The woman was struck in the leg, police said. She was taken to Grady Memorial Hospital.

All three shootings remain under investigation.
