An Atlanta woman is being credited with ending a potentially deadly carjacking after she discreetly let a police officer know that something was very wrong.

Atlanta Police Captain Rick Mason told Fox 5 Atlanta that he was on patrol when he noticed a car driving notably slowly in the opposite direction. It swerved toward him, allowing him to make eye contact with the woman in the front seat.

“She looked right at me and mouthed ‘Help Me,'” Captain Mason told the news station.

When the captain turned his car around to follow them, the woman and her husband took their cue that help was on the way. They reportedly stopped the car, jumped out and ran toward the police officer. After them, the alleged car jacker stepped out, stunned and confused.

A gun in his right hand, a panic look on his face, he ran around the back of his car, fumbled with the gun, jumps in the driver’s seat and hits the gas,” Captain Mason told Fox 5 Atlanta.

After a high speed chase caught on the patrol car dashcam, the suspect, Jeremy Summers crashed into another car. There were no reports of injuries, and Captain Mason was able to apprehend the 33-year-old man, who is now facing numerous charges. Earlier that same day, he had carjacked another vehicle.

The woman’s husband told Fox 5 Atlanta that he is grateful for saving their lives, and called her a hero.
