The short answer to your question is YES.
The charges that your daughter are facing are EXTREMELY SERIOUS. Even though she is a minor, there can be very negative consequences.
An attorney will be able to meet with your daughter, obtain documents (evidence) from the prosecutor that will be used against your daughter, speak to the detective in charge, and evaluate your daughter's involvement in the incident.
An attorney may be able to discuss a possible plea agreement with the prosecutor, including an agreement that would defer prosecution of the case for a period of time. Your daughter would be placed on probation for a period of time with conditions (ie. pay fines/costs/fees, obey all house rules, attend school, no absences, no tardies, community service, no further offenses, etc.). If she completes probation successfully, then the charges would be dismissed. That type of disposition would keep your daughter's record clean.
Depending upon the circumstances of your daughter's case, if there is a need to go to trial (your daughter maintains her innocence, which is her right), the attorney will be best able to advocate on her behalf. S/he knows the court rules, evidence rules, etc.
You would be best served by hiring an attorney. Make sure that s/he is qualified in juvenile law. You can contact your local bar association for a referral.
