Don’t mess with Texas.

A Dallas woman shot a suspected carjacker in the head after he tried swiping her SUV at a gas station — while her two small children were inside.

“I’m not a killer, but I do believe in defending what’s mine,” explained Michelle Booker-Hicks.

Speaking to FOX 4, the mother-of-two recounted what happened Wednesday night at the local Shell station near Interstate 35 — where she nearly lost both her car and children in one fell swoop.

Booker-Hicks had been paying for gas when she saw the male suspect climbing inside her SUV and attempting to drive away, according to police.

Her 2- and 4-year-old sons were in the backseat.

“I proceeded to jump in…and asked the gentleman to stop, to get out the car,” Booker-Hicks said. “He would not get out of the car.”

The suspect turned around and looked at the frantic mother — “with his eyes bugged” — but kept going, she said.

“I reached into the middle of my armrest, to get to my glove compartment,” Booker-Hicks told FOX, noting how she had a gun inside. “That’s when I fired at him.”

According to police, Booker-Hicks shot the man once in the face and caused him to crash into a nearby telephone pole. He was transported to a local hospital for treatment and is expected to face kidnapping and carjacking charges.

“I hope that woke him up,” Booker-Hicks said.
