SAN ANTONIO — One woman is lucky to be alive following an wreck on Bandera Road near Evers Road this morning on the city's northwest side. 

The accident occurred just after 3 a.m. 

According to police, the driver drove off the road hitting a metal guard rail, flipping the car on its side.

Two cars pulled over, one carrying two young men who filmed the wreck on their phone and another carrying off-duty St. Mary's University police officer Sgt. Kenneth Hamilton.

Hamilton was heading home after working at the University when he spotted the flames.

He asked the two young men if someone was in the car, to which they responded yes. 

The Sergeant ran over to the car as the flames intensified and worked to break the windshield.

"She was stuck in the seat belt so I reached in through the top and cut her seat belt so I reached in through the top cut her seat belt, she dropped and I pulled her out," said Hamilton.

He managed to get the woman out just before flames reached her feet. 

As the driver was pulled away from the car, the car became totally engulfed in seconds. 

Hamilton says he didn't hear the tires popping or the roar of the fire, he just focused on the mission of getting that woman to safety.

The woman was taken to University Hospital with minor injuries.
