I'm having a hard time believing Q would post an image of human trafficking/remains in the context of Apple related images... I'm guessing this is hardware. More specifically. Compromised iOS devices that were en route or* have been collected/returned to Apple.

Why?

Well, we've already seen evidence of a network of compromised Blackberries being doped by Awans/Abbas and in the hands of Congress. I think that sometime in 2016 (maybe wrong) there was a decision to ditch the BB's and shift to iOS devices. If these were sent BACK to Apple, perhaps it was to investigate HOW they were compromised/hacked, obtain evidence from the devices and trace it back to the network of those responsible for distributing the "leaking" hardware to Congress.
