I agree with Mr. Leroi -- hire a criminal defense attorney as soon as you can to understand all of the possibilities. The allegations are serious.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
The prosecution can choose to add additional charges in your case at any time up until the trial begins. I agree with my colleagues that you should retain an attorney now and have him/her deal with the Deputy D.A. when your case comes up for hearing.
