If you believe that there is a possibility that you will be charged with a criminal offense, you should start thinking about retaining a criminal defense attorney to represent you and to protect you against any negative fall out as the result of the charge or charges that may result.Since you are under 18 years of age, the charges if filed would place you in juvenile court which if you plea out or are convicted, your record would be sealed. Possibly you might be placed on court probation where if you adhere to the terms of your probation, the charge or charges if filed could be dismissed.Good luck.
