Unfortunately, unless the judge has specifically stated a time period for the property to be turned over back to you, it falls in the hands of the local police department. In Michigan, you have a right to a forefiture hearing to push the envelope if the police fail to return property previously confiscated due to the criminal offense. I would give the police a little more time, and then pursue a criminal defense attorney who has experience dealing with forefiture hearings in your area to seek the next step in forcing the police to turn over your property in a timely manner.
