(FOX 11) - A Fontana mother has been arrested after her children were locked in a hot car over the weekend.
It was in the parking lot of the Walmart in Ontario on Saturday where temperatures were nearly 100 degrees.
Some civilians and a security guard spotted two children, ages nine months and one year locked in this SUV.
The car was off and a window was cracked but the air conditioning was off.
Police and firefighters arrived and a few minutes later the mother walked up and unlocked the doors.
She was questioned while firefighters treated the children-- they were not transported to the hospital.
Ontario police arrested 34-year-old Crystal Gonzalez and she has been charged with child endangerment.
The two children were turned over to child protective services.
