She was mad, and drove right into him - maybe just to hurt him, but she was driving so fast that what the heck did she think would happen??
I figure the abuse thing, and the suicidal crap was all nicely invented after the fact.
The fact remains, she WENT there and CAME back - whatever they were fighting about was enough for her to snap, run him over, take off, and try to cover it up with a fake story. Her lack of credibility astounds me - at 17 and an A student - she must have a brain, so to conveniently forget things and then remember them bugs the hell out of me..and then when you read on line everybody has a different story and none of them match
Bottom line - it was vehicular manslaughter, or dangerous driving causing death or whatever you want to call it - she deserves the time..
