Replying to How to find where a teacher lives.

Alright so we have this dilemma. to begin, there is this physics teacher and everything about this guy is mysterious. My friends and I are destined to find he scoop about this man. Our main priority is to find where our teacher lives. This man is very safe with his personal life. We did a free background check and found out he has a P.O. Box. His Numbers unlisted and everytime we try to follow this man home he takes us for a "joyride" if you will. So my question is do any of you know where we can get more info such as his address by not following him home.
