I don't get it

Preliminary autopsy results on the death of three month old Natalie Hill indicate
that she bled to death as a result of rat bites last week.

I am wondering if the authorities have taken blood samples from the parents. I don't want to pass judgement until all the facts are in. This is too tragic.

And it's not only in Louisiana:


In Ohio, three people have been accused of letting rats bite a 6-week-old girl and chew off her toes at their cluttered home.
