NoVa burglaries

For those of you out in the hinterland, we've been suffering a bit of a crime spree here.  Over 100 burglaries in the last few weeks have been blamed on the same perpetrator.  Pretty impressive.  What's even more interesting is that no one has seen "him", and "he" has left virtually no clues.  I use the quotation marks because whoever is doing this is obviously an expert at not being noticed or appearing suspicious.  A middle aged white woman in a fancy jogging outfit would fit such a niche in most of the up-scale neighborhoods where the burglaries have been committed, (they almost never take anything but cash, one wouldn't need a satchel, or even a vehicle, to carry the haul).  My second guess would be someone with a Cox or Verizon truck.  The damn things are everywhere, hooking up or repairing cable lines; and the disguise comes equipped with a full tool belt and ladders - perfect for entering homes.  I'd be interested if either company has sold off or is missing any vehicles lately....
At any rate, we'll see what happens.
