Without a trace

Well, the joke about packing all the stuff in with paper was good. The thing that was NOT good at all is, that someone broke into the office right after it.
You don't understand it? Well, neither did I. Until yesterday...

The policeman left the office 15 mins ago. And that's what I told him:

Saturday in the morning two friends packed my office into paper. Two hours after they left you houskeeper wanted to clean the office but because there was no way in he left. Probably he forgot to close the back door. When I arrived at the office on Monday in the morning (I was in a hurry, I had to leave the second I entered the office) I didn't realize that anything was missing. I've noticed that the digital camera wasn't there but i rememberet that we lent it to a mate. and because of the special situation of all that paper I didn't think of anything else that that joke.

Yesterday, when I wanted to install the beamer I realized it wasn't there. I asked my mate but he didn't take it. Then I realized that the laptop was missing as well. And because it's always three I noticed that some money (SFr. 1500!!!!!) was not in it's place anymore.
Great. The door was open, the windows were closed, the robber had about 30 hours time to take out of the office whatever he or she wanted.
What makes me furious is that I didn't realize it before and that we extripated all the fingerprints and proofs. Without a trace...

Yes, shit happens...
