First, you need to make sure you DO NOT speak to the police at all, under any circumstances. I will say it again, DO NOT SPEAK TO THE POLICE.
Second, you need to sit down and speak with a criminal defense attorney as soon as possible. You need to get representation. My firm offers free consultations and we would be happy to speak with you further about this matter.
Nothing in this communication should be considered legal advice. Nor should this communication lead you to believe that an attorney-client relationship has been created. Only after thorough analysis of your case with you in my office can I provide effective legal advice on your specific issue.
