Dad Leaves 2-Year-Old Sleeping in Car During Arizona Heat Wave. She Was Later Found Unresponsive and Died

Authorities believe that the child could have been left in the vehicle anywhere from 30 minutes to an hour, and say the investigation is ongoing

A 2-year-old girl died after being left inside of a car alone on Tuesday, July 9, during the ongoing Arizona heatwave.

The Marana Police Department (MPD) said in a statement that initial information revealed the girl's dad "arrived home while she was asleep in the vehicle" and that he "left the vehicle on and running in the driveway, with the air conditioning on" while the child was inside it.

He then went inside. When the child's mother arrived home, "the child was discovered in the vehicle, which was no longer running and the air conditioning was off."

After calling for help, authorities arrived at the scene shortly after 4 p.m. local time.

The child was unresponsive and after attempting to resuscitate her, the child was "immediately transported to the hospital," where she was pronounced dead.
