A 3-year-old girl died at a Pomona, Southern California, hospital after she was found unconscious in a vehicle on Father's Day during a hot afternoon in Pomona.
Authorities said the death appears to be a "tragic" heat-related accident. The child remained in the vehicle after other family members exited outside a home on Rancho Jurupa Place at about 5 p.m.
"When they returned home, everybody exited the vehicle and, as is sometimes common, they assumed that the other children had unbuckled the infant," said Sgt. Marcus Perez, of the Pomona Police Department.
It was not immediately clear how long the girl was inside the car. Family members took a nap as the child remained in the vehicle, parked in the blazing sun in the driveway during a day of 90-degree heat.
"The windows were up, it was a very hot day," said Perez.
Authorities do not suspect foul play, Vasquez said.
