To mirror what MPfive 0 said... In my state, this would fall under "Theft by Deception" ... However, it is not uncommon to have the local Police Department come out and say it is a "Civil Matter"...... In many cases when that has happened, people have gone to the District Attorney's Office (whom has their own investigators etc) and the DAs Office will sometimes elect to take the case and charge appropriately... It is also highly likely that Restitution would be requested in any criminal prosecution. To try and make the victim (you) whole..... So, it may be worth speaking with your local DA's Office to see if they can help get the case into the courts... Terrible situation you're in. I hope you come out on top.
