You should contact an attorney as soon as possible. Even though there are some facts that are favorable for you, you are still charged with a serious crime and you will need an attorney to help you fight it.
You need to hire a criminal defense lawyer in your area ASAP. There may be a diversion program available for first offender. Your lawyer will know what options there are. Get counsel.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
