Sorry for your loss. The driver will go to prison but sadly he will be back out eventually. I know this is sounds really dumb to hear and it is something that I need to work on myself but I hope you find peace. One of my childhood friends died from an overdose and I was very angry at his "friends" for not taking him to the hospital but I am begining to realize I can't change the past and even after one of the idiots died I still didn't feel much better. Time is the only thing that will make you come to grips with this. Also be sure to celebrate his life at every chance.
