A summary...
She was driving drunk 25+ mph over the limit on the wrong side of the road. She killed a guy and she went to the hospital. While she was there - she tried to get an IV to dilute her blood alcohol concentration with an IV.
She got 15 years for pleading guilty to vehicular homicide, but will not serve any of the time after her sentence was suspended.
