Will She Go to Juvy?!?

My sister is sixteen years old and is currently “in the system.” She was arrested around sepetember of 2008. She had charges of domestic violence, destruction of property, and ID theft ( she did not steal someone’s identity…a debit card was in the wallet, although, just as bad.) She had to go through the Juvenile court system because the ID theft was a felony. Her case was DISMISSED on March 6, 2009. She was not on probation or anything. On the night of March 6, she was arrested for falsification (lying to a police officer), underage consumption of alcohol, and cigarettes. My family & i are very concerned as to what may happen to her. Would it be probation, community service, house arrest? Or even juvenile detention center? Help!
…
I would like to add that she is, besides all this, a generally good kid. She has a great positive attitude with straight a’s and is also involved in a lot of extracurriculars ( she is an outstanding athlete). She also goes to an alcohol and drug abuse outpatient rehab as it is, would this help her out any?
