"Keys are missing" on one and another that says needs locks. Repos maybe ? Possibly the guy is a tool dealer and they are trade ins ? Who knows. I think it would take a huge set of nads or a very small brain to show pictures of stolen boxes on Craigslist. Here in East Tennessee I go to alot of auctions and there have been many times where the seller had large lots of power tools and sometimes boxes & they had pawn shop stickers on them listing the date they were pawned, what the loan value was, etc. I got a nice electric grinder in a case with about a $100 assortment of grinding stones, cutoff wheels, etc. all for 10 bucks a few weeks ago.
