In that case, the victim was a billionaire's grandson (these things matter in Texas) and the killer actually injected the victim with the heroine which killed him.
I think it's a little early to be forming a lynch mob. The facts will come out. These kids are probably lawyered up, so it might actually be a very long time before all of the facts are known.
