Images and videos all disappeared from Motorola phone

Hey everyone, my boyfriend woke up this morning with everything gone from his phone. It froze for like an hour a bit ago and he couldn’t do anything and now everything is gone.

He’s somewhat phone tech wavy so he’s don’t a lot of the basic things like check the trash folder, archived, and he cant find them.

Any idea on how this can be recovered ? He’s very very upset as you can imagine !!!

I told him I feel like they’re somewhere they don’t just disappear.

Has anyone had this happen before? And what did you do to fix this?
