What do you think will happen to my case?

If you are being charged as a juvenile probably probation and community service. By the way please please think before you act in the future. Do not throw your life away before it starts. You are only 16 with plenty of time to change. Go back to school get your High School degree then go to college. You have the ability. You have brains because you would not have been on the website if you did not.
