Police arrested a 17-year-old boy and identified two other suspects Thursday in a violent DeKalb County carjacking that sent a 74-year-old woman to a hospital last week.

Aaron Johnson is facing charges of robbery by force and elder abuse in the incident last Thursday at a Chevron gas station on the corner of Gresham and Cook roads.

At a news conference Thursday night, DeKalb police said Joshua Bryant, 20, and Tiffany Swanson, 19, are also wanted in connection with the crime.

The victim, Rosa Smith, was punched repeatedly in the face before her attacker took off in her red Nissan Rogue, according to police.

Smith’s terrier mix Daphne was still inside the vehicle. The dog was found wandering in the road later Thursday night in southwest Atlanta and has been reunited with her family.

Smith, a retired attorney, was hospitalized following the attack. She didn’t suffer any broken bones, but she was left battered and bruised with gashes on her forehead, mouth and cheeks, according to police. She also complained of extreme pain in her hips.

In surveillance video of the incident, Smith was left on the ground in the parking lot. The vehicle has not been recovered.
