Maybe its me, but if the thief already knew the building the car was located it would be trivial to find out the unit the author lives in and could show up looking for his missing wax.
True, but I don't think the thief knows that the police gave them to me! Additionally, the DA said this person has a criminal history and may end up going to prison for this offense. In any case, if they did show up, they'd do so whether I have the records still or not!
