My question involves criminal law for the state of: Virginia
I am 18 and my boyfriend is 22. We were sitting on a bench at night time when cops came up to us and started asking us questions. He had an open alcohol bottle on him and more beers in his backpack, which one cop found after searching him. I was searched as well and had nothing. I was then given a breathalyzer test and blew a .031, which came from me having some of my guy's beer in a restaurant in another jurisdiction. The cop asked me if my boyfriend bought the alcohol and gave it to me, I was scared and worried for him and tried to say that I bought it (a mistake I'm really worried about now). He knew I was lying and got me to admit that he bought it. I didn't say that he gave it to me, though. I was charged with Underage Possession and my boyfriend was charged with Trespassing and being drunk in public.
I was appointed a public defender, but am beginning to wonder if I should find the funds to hire a lawyer instead. My public defender has not told me what I should be expecting in the actual court case. All that she has said so far is that she doesn't think the cops had a valid reason to charge my boyfriend with trespassing. I plead not guilty. Do I have any grounds to stand on? Would I still be found guilty of possession in court?
