What could happen if a minor is on probation and home supervision, and goes on the run, until he turns 18. Also what could happen if he was to turn himself in, the day before he turns 18.What if the police are trying to say, he was in a fight, and cut someone. I know that I will probably need a Lawyer, because he says, he hasn't done such a thing , and they have the wrong person. He was 17 when it supposedly happened. If he turns himself in a couple days before he turns 18, will he still be tried as a minor, or an adul,. if charge him with it ?. Also if he has taken a polygraph and passed it, me being his mother, am I allowed to obtain a copy of it ? and if so from who. Thank you all for your response.
