If they did know who the killer was and it was a family member...I think it was kept quiet.
Her family was rich and they more or less had powerful friends, including the police.
So if it was one of them, I think it was all covered up so no one did time :\
You'd think that would never happen but it does.
There was another case where this woman who was a cop, killed her on and off boyfriend's wife.
When someone reviewing the case started noticing "Hey, this cop seems suspicious >>" she took it to the the other police and they more or less threatened her to stop working on it.
The cops knew a fellow cop did it and they covered it up.
BUT she was eventually found guilty and is doing time 8u
So no matter who you are, you will one day face judgment. Whether you're alive or dead, you will face it eventually.
I have a major soft spot for animals, the elderly, and little kids.
Anyone who hurts or kills them is just the world's biggest coward in my book.
