i know its too late now, but for future reference, its always a good idea to walk around the vicinity of where your theft happened, and look in trash cans, dumpsters, out of the way areas for your shit.
a lot of times what happens is they grab the purse/bookbag/briefcase whatever out of your car then dip out. they go through it, take what they want and then ditch the bag.
i had my shit broken into once and i found my bookbag in a trash can about a block away. still had the books in it too. not surprising, since i highly doubt someone who breaks into cars on the regular is even literate.
