Is is sad indeed, so much potential and talent. Alcoholism is a disease, but we all make choices.
I recalled that in the early 2000's he was arrested for battery on his girlfriend after drinking at the Classy Chassis. I don't remember how the case was resolved, and he has picked up at least two more OWI's since then.
It will be interesting to see what the BAC turns out to be. As noted above, this is going to be one expensive criminal defense for Mr. Unser.
Surprised I didn't run into him at the Classy Chassy. That's about the time (mid-life crisis ) that I was hanging out there a lot (2002). I even had a VIP card - no cover for me and a guest any time!
