when you are the plaintiff you must prove your case. So, you say; you went into my apartment. They say; no we didn't. They win because you have not proven your case. So, how do you prove your claim? How do you prove they are lying?
So, what do you have to prove your case?
So the door was locked. That suggests somebody has a key. Is the landlord the only one other than you with a key? I don't know.
maybe your apartment was broken into and nobody realized it.
again, you have to prove your claim and nothing so far proves anything other than you are missing some stuff.
another thought; how are you certain you locked the door when you left? After all you were packing until 4am. You must have been dog tired. Maybe you forgot to lock the door.
