Under no circumstances should you speak with the police without an attorney being present. The fact is that you are under no obligation to do so. You could say something incriminating about yourself regarding the investigation. In fact, even if the police come to your home to question you, you do not need to speak with them. The fact is that questioning you without your having a lawyer is to their benefit. They can try and get you to implicate yourself. At this point you should consult with a criminal law attorney ASAP.
