No, there is definitely a place (in fact, there are lots of places)- and it could have a body.

The fact that you have a phone, which could contain something, doesn't make the phone case any different.

Which you might not have the password for. You could've recently changed it and forgotten it (I've had to reset phones of friends and family who have done this). Or you never locked it but someone else did. Or a number of other situations where the password, like the body, might not exist.
