I'm 18... Me and a friend were drinking at his house, we stopped drinking and he went to bed, I was an idiot and tried driving home, wrecked then drove back to his house and his brother woke his parents to tell them I was drinking and wrecked, I fell asleep on the couch and his parents were concerned about his breathing and called 911 for him.... the ambulance and police showed up and saw me sleeping on the couch with a few minor scratches on my head so they breathalyzed me and took me to the hospital. I was way over the limit with a .2 something. A few days later I got a call saying I was being charged with underage drinking and couldn't be charged with D.U.I. because they couldn't find were I wrecked and didn't pull me over. And they also couldn't find the bottle of liquor. What are my defense if any in this case?
