Under no circumstances should you go in for fingerprinting or speak with the police without an attorney present.  You are under no obligation to do so (unless they have an actual warrant).  You do not have to voluntarily put yourself in a position to incriminate yourself. In fact, even if the police come to your home to question you about this case, you do not need to speak with them. Getting you to come in, at least without an attorney, is to their benefit. They will only try and get you to implicate yourself.  No matter how low friendly they may appear, or conversely, no matter how intimidating they seem - do go down to the police station without a lawyer.  At this point you should consult directly on the matter with a criminal law attorney in your area.
