TUCSON, Ariz. (AP) — Police in southern Arizona say a 7-month-old girl died this week after being left in a car for up to eight hours before her father noticed her unconscious in the backseat.

Tucson police have identified the baby as Isabel Ledo Herrera but say they are withholding some information as the investigation continues. No arrests have been made.

Sgt. Chris Widmer says detectives confirmed that the father was driving his vehicle and that he didn’t know anyone else was in it. Widmer says the father immediately called 911 when he noticed his daughter.

Authorities received a 911 call at 5:19 p.m. Wednesday. The girl died at a hospital after firefighters found her unresponsive.

Widmer says preliminary information indicates the child was in the car for as long as eight hours.
