I don't know that I would want to see the person either.
Does this person feel remorse for what they have caused you & your family? Not that it can bring Amylynn back but maybe if you heard it directly from the source you may feel more relief.
I'm not trying to say you shouldn't be upset & angry or hurt, but was this accident the 1st time he's been drunk behind the wheel?
I'm just asking because part of this story hits close to home for me & I know a person that would be extemely hurt & sad if anything were to come of his mistake/s. (not your situation however)
Personally, I've never been in your situation & can not tell you what to do. You have to go with what your heart tells you to do. That's all I'm going to say!
Good Luck & I'm Deeply Sorry for your loss!
