Where the heck are my tubs?

I just went into the attic to get down some storage tubs for a quick sweep of the floor, and there were only 3. Lots and lots of lids and no boxes. My dad and my brother straightened up the attic when they were working up there, and a conspicuous thing missing is the 2 huge stacks of empty storage tubs that I had placed to the right of the attic opening, so that I wouldn't have to sift through the spiders when I needed one.

They're gone. Just the lids remain, and Dad knows nothing about it, of course. Did my brother take them? Or maybe it was that guy he hired to do my roof, who's now in jail for theft and drugs?

That's just great though. I have nothing to put this junk in, to keep the puppy safe.
