Missing MacBook

Hi all,
There was a partially dissasembled MacBook Air that I had ordered some new parts for sitting on a shelf (next to the entry to the workshop) that I had tentatively reserved and was using to store a number of my other items, however I had not lableded the shelf (a mistake i will not make again).
Through my cleaning, I have recovered all the other items, however the laptop is still missing. I was wondering if anyone might know where it could be?
I know this is my fault for not labeling the shelf, but help is appreciated none the less.
Cheers, Ryan.

Hopefully this should clear things up.
