This murderous creep has a history of domestic violence. He has dead eyes in a previous booking photo.

And yet, according to the article, he had custody of this little girl.
A bit more digging to find out why:
Mom has MS; father had full custody (ABC Action News)
It still doesn't make sense.
This guy was charged with domestic battery 6 times. (Domestic violence means nothing to the courts in custody cases.) Apparently this final act was revenge against the mother who'd started dating someone else.
