I parked my 2005 SE Taurus in a city on a lighted street with parking meters. Left the car there for 3 hours, it was locked, alarm system set & operating, windows closed tight, only one key and it was in my possession. When I returned the front windows were both wide open, glove compartment opened and all the stuff left on the front seats, had golf clubs in the truck but were not taken, nothing I could tell was stolen. Question is how can someone enter the car and then roll down the windows when I have the only key and the windows won't operate without the key in the ignition? I saw no entry marks, scratches and the hood was closed. No forced entry from what I could tell. Cops could not answer how, nor could my insurance agent or garage mechanic.
