If you have receipts for an iDevice and you have the iDevice in your possesion, Apple could just unlock the device. They could also lock the device to an iCloud account even if the user doesn't enable FindMyDevice on it.
And I will re-iterate, what's with all this risk management from unpaid volunteers for the biggest tech company in the world? :)
An old invoice doesn’t necessarily indicate current ownership. I have the invoice of pretty much everything I’ve purchased in the past decade (I scan in anything physical), including for a lot of items that I no longer have ownership of.
Unfortunately, except for the invoice, all of the other evidence pointed to the blogger _not_ being the current owner.
If you have the receipt, and ID showing your picture and the name under which I ordered the device, and can receive physical mail at the address to which the device was shipped, and/or at the address listed on the cloud account that we both know the device effectively forced me to create, then yes.
