A 17-year-old from Gwinnett County has been arrested in connection with a Roswell hit-and-run that critically injured two women in their 70s Saturday morning, according to authorities.

Officers got a call from a passerby reporting two injured pedestrians along Roxburgh Drive in the Country Club of Roswell around 6:30 a.m., police said. When they arrived, they found the women with critical injuries. An update on their conditions was not provided.

Using evidence left at the scene and license plate readers, police determined the suspected vehicle was a white 1996 Honda Civic, according to a police statement. Investigators then learned the alleged driver was Gerardo Ordaz.

The teenager was located later the same day and arrested, police said. He was booked into the Fulton County jail on two counts of hit-and-run, two counts of serious injury by vehicle, failure to exercise due care and driving while unlicensed.

No other details were released by police.

The investigation remains ongoing. Anyone with additional information is asked to contact Roswell police at 770-640-4100. Anonymous information can be provided through Crime Stoppers Atlanta at 404-577-TIPS (8477) or online at www.StopCrimeATL.org.
