Getting behind the wheel with the kind of BAC she had is an incredibly dangerous, selfish, and short-sighted decision. And it's apparently one she'd made before, given her track record of "tearing up" previous vehicles.
When you do that, there is a very good chance you will end up ruining/ending your own life and the lives of others. Which is exactly what happened here, because of her decision to get behind the wheel absolutely plastered. Wtf was her BAC at the time of the crash, I wonder? And she had an enabling family who kept helping her get more vehicles...
The way she ended up losing her life and ruining someone else's is a bit novel, but it's still a predictable result of that kind of enormously intoxicated driving.
Charges may have been appropriate, and it may be appropriate for him to stand trial... but I can't help but feel bad for someone who is simply asleep in their home, someone who has dealt with previous burglaries, and who suddenly is awoken and scared shitless by what he believes is another break in... and his life effectively is over because he didn't handle it better.
I really wish we could know what really went down exactly. Because there are in fact versions of his actions which would make me lose ALL sympathy for him. I just find it hard to believe that those versions are likely. It seems more likely he really was afraid.
Sucks for her and for him that she conducted herself in such a highly illegal way that night which resulted in her needing to be at his doorstep.
