Quick and easy:
1- Make a police report if you have not already done so;
2- Send a copy of the report to all of the big three credit reporting agencies, Equifax, Experian, Trans Union;
3- Get a good consumer attorney at either NACA or MyFairCredit, linked below
Good luck with it.
I agree with the prior poster, that you should be able to get the identity theft items off your credit report, along with getting the collectors off your case. You may have to hire an attorney to assist you if your own disputes do not result in the items being removed, but most reputable consumer attorneys will take this type of case on a contingency basis if they believe your story is truthful, and they can try to obtain monetary damages for you. The prior poster was correct about that National Association of Consumer Advocates' web site as being a good place to find such an attorney. As far as pursuing the ID thief, unfortunately, that is best dealt with by the criminal side of the court system (and sadly, going after ID thieves is often a low priority in many jurisdictions). Most private attorneys won't be willing to go after the actual ID thief because it is too hard to collect from somebody like that, assuming you can even find them to serve them with the lawsuit.
