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

The investigator told The Blade in Toledo that the baby girl, identified as Makayla Darnell, suffered head trauma at a home near Beaverdam in northern Allen County on Thursday evening. 

"It all appeared to happen in a matter of seconds," Steve Kahle, investigator with the Lucas County coroner, told the newspaper. 

He said the girl's parents, Audrianna Myers and Jared Darnell, 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.
