Hmm...was this a dog attack, or a murder staged to look like one?
Both possibilities should be investigated. Particularly if the husband and wife didn’t get along.
If the dog is at fault, put down the dog.
If the husband is at fault, then give him the death penalty.
Ever seen the movie “They Only Kill Their Masters”?
Five minutes into it, the Dobermann is condemned as the killer of his female owner.
At the end [spoiler alert] it’s discovered that the ex and his new girlfriend did it.
Only in the movies do people bother to fact check a ‘dog attack’ before they condemn the dog.
Perfect crime.
You can’t cross-examine the accused but you can just put a bullet in its head.
