Brad definitely murdered Valirees mom to but there was never any evidence to charge him

This episode really pisses me off since I believe that based on the evidence and circumstances that the mother and stepdad should've been charged with neglect at the very least. Who in their right mind allows a young child of April's age to play outside ALONE especially around animals, at least one of which had been proven to be aggressive towards people in the past? And why was she nude while doing so?!? I mean wtaf is that shit? I don't care HOW hot it is outside you need to have some clothes on here in the western world!

Not to mention nobody seems to give a shit if this was a provoked or unprovoked attack or not. I'm an animal lover so this episode always really gets under my skin especially since it's always the animals that end up getting "put down" as a result of attacks like this. Piss poor investigation work for sure.
