Aaliyah Felder, 6, was recently killed in a car crash. The automobile was driven by her eight-year-old brother.
The mom bathed the children and put them to bed at 9:30 p.m. on Wednesday night, and then went to bed at 10 p.m.
Before she noticed the kids were missing and called 9-1-1, Phoenix police received several calls from people who reported seeing the car (video below).
One caller said the car hit fence and then drove off, while another caller said the car was being driven by a child.
Two police officers spotted the car, but it crashed into a pole after police turned on their emergency lights.
The boy suffered an ankle injury, but Aaliyah died on Thursday from her injuries.
According to police, her seat belt was not fastened and her airbag failed to work.
"First believing that her children were kidnapped, then to discover that it was her eight-year-old son who took this vehicle and now her six-year-old daughter was involved in this fatal collision, extremely traumatic for her," Sergeant Steve Martos told AZFamily.com.
The fatal car crash happened only a block from the apartment where the family lived.
According to police, the children drove three miles from their home and then backtracked.
Joshua Garcia, 8, survived a car crash into a river, swam ashore, walked a mile barefoot to his home, woke up his mother and asked her to call 911 to save his injured father.
While the boy is being called a hero, the dad may be facing arrest (video below).
Early Thursday morning, Eugene Garcia was driving a car with his son Joshua as his passenger in Fitchburg, Massachusetts. Eugene's car hit a guardrail, flew into the air and landed on a sand bar in the Nashua River at 3 a.m.
Eugene was trapped in the car, but Joshua was able to make it out and his dad was eventually rescued.
Authorities told ABC News that speeding may have been the cause of the accident, but would not comment on any potential charges.
The Fitchburg Police Department called Joshua a "hero" and Joshua’s aunt Priscila Columna told CBS Boston: "I’m really proud of him, he was brave."
However, after Joshua and his father were treated at the Health Alliance hospital in Leominster, Massachusetts, the Department of Children and Family Services removed Joshua from his parents' custody.
The Department of Children and Family Services claims that it has to investigate the family, the crash and why father and son were driving in the middle of the night, which is lawful in Massachusetts.
