You should consult with a criminal law attorney ASAP. The fact is that you should not speak with the police until you do; this is true even if they come to your house. That having been said, if you recognized yourself, chances are that somebody else did as well, so the police will more than likely get your name. The best thing for you to do if to go to them first and explain things. However, to repeat, do not allow yourself to be questioned regarding this incident without legal representation. The authorities are experts at getting people to incriminate themselves or others, whether or not they are innocent.
