This is not a do it yourself case. You should not surrender yourself and try to explain to the police why you are innocent. The prosecutor will use your words against you. An experienced criminal defense attorney could arrange your surrender and may be able to help you get bail or release on your own recognizance. The attorney could also point out to the prosecutor that this is an old case. Apparently, the police never bothered to execute the warrant. Perhaps the antiques were returned. In fact, the warrant may already have been vacated and the background check was based on out of date information. Get yourself an experienced criminal defense attorney as soon as possible.
