State police are investigating the death of a 15-month-old girl left inside a vehicle for about seven hours while it was parked at her grandfather's central New York home.

Troopers in Herkimer County say they received a call around 2:30 p.m. Wednesday reporting an unresponsive infant in a vehicle parked in a driveway in the village of Dolgeville (DAHLJ'-vihl). That's in the Mohawk Valley, about 60 miles west of Albany.

Police say the baby's father had dropped off two other children at school around 8 a.m. and brought a third child to a relative's house before driving to the baby's grandfather's house.

Police say the father appears to have left the infant in the vehicle after leaving for work in a different vehicle. High temperatures Wednesday were in the low 70s.
