A 2-year-old girl has died after her father left her in a hot car in Arizona, where residents are enduring triple-digit temperatures, according to authorities.

The father was running errands with his daughter, and when he returned home Tuesday afternoon, he allegedly knowingly left the 2-year-old in the car, Marana Police Capt. Tim Brunenkant told ABC News.

He left the car running and the air conditioning on, Brunenkant said.
