Well stated. It just goes to show how painful something like this is and that even after 28 years the father is still in deep agony. It's against the natural order of things. Kids aren't supposed to die before the parents.
I don't know WTF is up with the 'justice' system. Remember that SOB that abducted a girl from a sleepover, raped and killed her, and the judge allowed him to address the court giving him an opportunity to say something like, "she told me just don't do me like my daddy does?"
If I were the father I would be silent on the topic and arrange things rather than being so vocal. A piece of human refuse like that isn't worth prison and there would be plenty of people much more skilled at eliminating people like this.
Revenge is a dish best served cold and there's no murder if nobody ever finds the body.
