I merged this topic with an older one that deals with the same subject. Doktor, I suggest you check out the previous posts.
What it boils down to is that Kickstarter will do NOTHING, other than to tell you to contact the local authorities.
You may be able to bring a case against him if you can present your evidence to his state's attorney general's office. You could try it in your own state, but it seems to make more sense to pursue him using his own state's AG. I haven't checked for updates in a while, but another person, I think the guy in charge of the Founders deck debacle, was being pursued in New York by the AG here after said AG received enough complaints.
Gather together other dissatisfied backers and get them behind this - it will lend a LOT more weight to the issue and make the AG more inclined to pursue a fraud case when presented with dozens if not hundreds of victims.
Be prepared for the process to take months, if not years. Nothing moves quickly through the courts anymore, at least not in New York. Also consider that receiving the full amount of your investment is very unlikely, though there is a chance you'll get some portion of it back if the AG is successful. It will largely depend on the con man's available funds and assets which can be liquidated.
