Most trials I've watched (and admittedly it hasn't been a ton) have been quirky and strange to one degree or another. I've seen parents pointed at as if they were the perp, victims blamed for their own deaths, groupies formed for men who are eventually found guilty and end up on death row, murder cases bring out the strange, along with the regular folk. You always see lots of crazy theories, usually some theory includes some drug lord or drug party, lots of 'vans' talked about, friends of the victims pointed at. It does show a certain pattern as these kinds of cases progress.
The only thing guaranteed is that in the end the victim(s) stay dead, hearts are broken forever by those who loved them, people get hurt along the way (innocent people), and while there might be legal justice, there can never really be closure.
