Legal Question in Criminal Law in North Carolina

I am not quite sure what you want to report.

If you are upset that you feel that your friend lied, unfortunately no crime as occured. Lying to people is not criminal. Your friend would have committed a crime if she reported false allegations to the police or child protective services.

If you feel that your friend really is in trouble and adults are covering it up, you may want to speak to another adult that you trust, someone liek the guidance counselor at your school. Allegations like these can be very dangerous, especially if false...or if they are true and the adults are able to cover it up, your friend may be further victimized and encouraged never to try and seek help when she is ready.

What? You heard all those things and chose not to report them at the time - presumably over the course of 3 years! Now that you have been told they are untrue, you want to report something that didn't happen or that you were possibly lied to? I believe your priorities are a bit out of order. Why don't you consider talking to a school or other counselor as to what may be be best course here because after all you don't really know anything other than what you have been told. It could certianly be the case that your friend is telling the truth and the person who told you she is lying could be covering up for someone.
