IF anything, I'm a true dumba$$ when it comes to tech stuff. I do know that there are apps for this type of recovery off smart devices & more so you well know that LE forensic techs are super capable---burner phones probably pose different approaches. But... what we put out there digitally can be followed back thru that 'path' it takes. I want to ask a friend more, who was a state trooper & is now with our state ATF, about this. He did online investigating into pedofiles posing as young kids in social media (his assignment between trooper & ATF duty). As I said, that digital trail lives forever.
