An Ohio coroner's investigator said a 3-day-old infant died hours after she was attacked by a family dog while sitting in a swing.

The investigator told The Blade in Toledo the baby girl suffered head trauma at a home near Beaverdam in northern Allen County on Thursday evening. He said the attack apparently lasted only seconds.

He said the girl's parents were in a different room and said they didn't hear noises from the dog or the infant.

She was flown to a Toledo hospital, where she died. An autopsy was planned.

A sheriff's officer said the dog appeared to be a "pit bull" mix. It was put in the custody of the county dog warden.
