Whew!
The one thing I'd advise you to do is to stay firm. It's very common for a student to be caught in a crime and then his/her friends or parents will come put heavy pressure on the victim to drop the charges; I saw it happen many times in the past year. Those who think they're "helping" the student don't realize that another offense is likely to happen shortly.
Stay strong! See it through to the end, no matter how much you're pressured; enlist your friends' and parent's help too!
