A wild police chase in Dallas Wednesday came to an end thanks to a protective mother. 

Authorities say they were chasing a robbery suspect in a stolen Dodge Challenger when he crashed into a minivan.

Minivan driver Jessica Liesmann dragged the suspect out of the car and pinned him down with her boyfriend until police arrived at the scene. 

KDFW reported:

“I asked [Alexander], ‘What is wrong with you? What are you thinking? You're in a school zone!'” said Liesmann. “And he had nothing to say and acted like he was trying to run, so I remember kicking the door. All I can think about from there is, ‘You're not getting away, you're not getting away.'”

Liesmann had just picked up her 13-year-old son, T.J., from school and was going to get her daughter when they were hit.

T.J. was in the backseat and took the brunt of the impact, but he quickly forgot the pain.

“I just saw my mom go, ‘Whack! Whack! Whack!'” said T.J. “My stepdad slammed him on the ground and that's about it.”

Police later found a gun in the Challenger that Alexander is accused of stealing -- something Liesmann is grateful Alexander didn't use on her.
