KATY, Texas -- Some shoppers jumped into action Monday, smashing open a car after spotting children inside as temperatures hovered above 90 degrees.

They thought they had no time to spare, so shoppers in a parking lot took matters into their own hands after noticing two small children in a hot Jeep.

"It was a crazy situation man," Gabriel Del Valle said.

Del Valle stepped out of his nearby shop after hearing the sound of children crying out in desperation.

"The kids were in there crying," he said. "I mean you would understand. It's real hot."

Del Valle shot video with his phone. He says one man used a hammer to smash open the windows.

"Even then they could barely open the doors because there was a child lock on," Del Valle said.

After several minutes, the kids were freed. The children's mother apparently said she had left them there only temporarily so she could get a haircut.

But Del Valle said nothing justifies treating children like this.

"Even a dog can die," he said. "Imagine a person."

The mother came out and pleaded with everyone, saying she just made a terrible mistake. Police were not called.
