At my work, they recently cleared out the lost and found and were going to trash stuff. I ended up with a clean practically new iPad. The previous owner was not contactable for over a year. He left his Apple details on and his passcode was 12345 (I kid you not). I want to unlock it from his Apple account so that I can hard reset it. What can I do here?

*Edit: So, after exploring it a bit more, I found a password list in the Passwords. Literally, the first password I put in was the correct one. Lol. It has been freed.
