I haven't read this thread, so I may be repeating other people's advice, but my general advice would be this:
(1) Stop posting in this thread or saying saying anything that has anything to do with this situation. Don't even post what the police might have told you. Nothing you post is in any way going to help you, and you never know how some seemingly benign comment might be used against you at a later date. There is just no advantage, for you, in discussing the issue in a public setting.
(2) Get legal counsel asap. If you can't afford a lawyer, get one appointed by the court.
(3) Do not under any circumstances speak to the police or a DA for any reason, unless your lawyer advises you to do so. Period. If they already believe you have done something criminal, you aren't going to help yourself by speaking to them. If they try to contact you, tell them you are not speaking to them anymore accept through or in the presence of your lawyer. If they ask you what your favorite color is - do not answer.
That is general advice, and not specific to your situation. That is why you need legal counsel - to get advice appropriate to your specific situation.
