(Portland, OR)  --  A man who's accused of a hit-and-run crash in Gresham that seriously injured three people reportedly told police he had fallen asleep at the wheel.  KATU-TV quotes court documents as saying 33-year-old Sky Marsh told police he woke up to a "bang, boom, and boom" but that he continued driving.  Marsh reportedly told investigators he had a drink of whiskey at a Portland Trail Blazers game and later drank ginger ale at a bar prior to the Friday morning crash on Southeast 181st Avenue.  Marsh is facing multiple charges, including assault and reckless endangering.
