Police spokeswoman Julie Parker says 8-year-old Natalie Hernandez-Cruz has died of her injuries. Another child is in critical condition, and the three others have minor injuries.
Parker says Natalie's mother, Maria Anna Cruz-Lopez, mistakenly stepped on the accelerator instead of the brakes and accidentally drove her SUV into the children around 8:45 p.m. Thursday. She says the mother has not been charged, and alcohol and drugs aren't a factor.
Police are trying to determine the relationship between the woman and the other children.
