Jeez, aren’t we attorney-happy enough already? What happened to innocent until proven guilty? Are you sure he was in the house? Why don’t you just ask him? Or tell him what happened (you saw him in the driveway, the door was unlocked, etc). Before running to a lawyer, why not give the guy the benefit of the doubt or at least give him a chance to explain? What if he wanted to leave you an easter basket? 🙂 The whole shower/door/driveway story would never hold up in court, and it will make any judge think you are a “jump the gun” type of renter who goes around making reckless accusations (which will doubtlessly cause him to favor the landlord). If you suspect the guy, set up a sting operation and catch him in the act with video if possible. THEN think about getting a lawyer.
