Contributing to the Delinquency of a Minor is a class 4 felony, meaninf the maximum penalty is two to six years in the Colorado Department of Corrections. Is that worth hoping for a good eresult without counsel?
Get an attorney. Now.
As a former prosecutor, I can tell you judges do not like these sorts of cases at all and they tend to sentence sternly. Not only did you do something stupid, you had kids doing stupid things, too. Your history (or lack therof) helps, but it is not going to just carry the day.
Good luck to you.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
