Whatever...
Which part do you disagree with?
Did the mother party like a rock star in the days after her daughter's death (a death she was clearly aware of)?
Did her greaseball mother and father both have knowledge of the death of the child?
Did they all lie to the police?
Did they all conspire to cover up the murder?
Did the parents stand quietly by while their daughter fed misinformation to the police and media?
Which of that is untrue? Which is the behavior to be commended? Who won?
I'd like to kill a lot of people. They just moved up the list. I'd laugh if they died in a burning building. I'd be happy if a mountain lion got in their house and mauled them to death. I'd snicker of a swarm of african bees stung them all to death.
