A 3-year-old southern California girl died in a hot car outside her family's Orange County apartment complex amid 104-degree temperatures Friday, and her mother is charged in the toddler's death. Making the tragedy even more unimaginable: The girl's brothers were killed at ages 5 and 9 in 2012 when a drunk driver ran over their tent at a campground in North Dakota. Their father, Juan Ruiz, was also injured in that incident. He and wife Sandra Hernandez-Cazares went on to become advocates for harsher DUI penalties—and to have more children, including Ily Ruiz, who died Friday, CBS News reports. Family members were alerted to the emergency when staff from the girl's 5-year-old brother's school called to say no one had picked up the boy, and relatives went to the Anaheim home to find the toddler and her mother unconscious inside the family SUV.
