I reckon it was the courier that did it. I worked at a computer shop (special needs / education sector, so not a competitor!) for several years. We'd send laptops RTB for warranty repairs, and a few times a year, the manu would receive an empty box. What was happening, was the depot staff would slit the box underneath, pull the laptop out, then re-seal it with parcel tape. As laptop boxes normally have a carrying handle and the underneath wasn't in view, the driver was none the wiser. Cue disgruntled customer for not backing up their data, and disgruntled computer shop for having to foot the bill. This wasn't a single courier company btw... Fedex, Citylink, DHL... They got away with it because the depot staff are usually students / temps and tend to move on from the 'crime scene' sharpish.
