Narrative:

IFR flight terminated just after midnight. The tower and the approach services were both closed. Center provided GPS approach to runway 1. I monitored the local frequency until on final approach and then recontacted center with my tail number and requested cancellation of IFR flight in the air. Center responded; and I believed that my IFR flight was cancelled. The landing was normal. One hour later I was contacted by the local police who were sent to find the pilot of a missing aircraft. I called 1-800-wxbrief and they relayed the flight plan closure to center and told me that no additional action was required.in the future; when landing at an untowered (or tower closed) airport; I will make extra effort to communicate an IFR flight plan closure and make sure that I definitely am told that IFR cancellation is received.
