I wouldn't totally discount the possibility that Alex moved it, but if it was plugged in that does seem strange. When you first called it 'portable' I thought it might have been easy for one of you to move it and forget, but it doesn't sound like that's the case. It's more appealing than the idea of someone breaking in, though, and it's very strange that nothing else would be moved or taken. On the other hand, if you're sure it's a break-in, I'd report it on general principle, even if you haven't (yet?) noticed anything of large value gone.
