We had a similar story here in Calvert County. One story said the dog was munching on her intestines. https://patch.com/maryland/edgewater/calvert-county-woman-fatally-mauled-fiancees-dog
I looked up the one I posted and she WAS another that was indeed killed then eaten. She was found disemboweled and totally naked except for a single shoe. They ate so much of her their stools had her hair in it.
She had raised those dogs from pups by the way.
