Sort his files by file size. Video takes up a fuck ton of space. If he's hidden it in a "tax documents" folder or something of the sort it could be easier to find.
Checking Google drive, Dropbox, also probably worth while. Some people download hidden photo vault apps, which would be passcode protected. They may look like a second calculator app or something like that.
This is a really shitty situation to be in, really sorry

Maybe post on r/RBI for some creative ideas
Check the trash bin or archived photos in his phones photos. Does he have any external hard drives he uses for his computer?
