Got home. Put key in lock. Turned. Met no resistance. Pulled key out. Cylinder came out of lock with key. Looked closely — heavily scratched around the key entry. Freaked.
Went in another door. Entertainment unit still there. Computers still there. Music equipment still there. Digital camera still lying in plain sight on desk. Called cops. Called landlord to come replace lock.
Waiting for cops.
Update #1: Got a call from the Sheriff's office. "Just want to let you know, we haven't forgotten about you! We're really busy tonight, but a deputy will be there."
"Okay, thanks. Any idea of a rough timeframe?"
"He should be there within half an hour, forty-five minutes at the most. Are you in an apartment or a house?"
"A house."
"Well, I can't promise you anything, but he should be there even sooner then."
Hmmm.
Update #2: It's been more than forty-five minutes. I'm missing my Oktoberfest dinner, damn it!
Update #3: No usable prints. But the case is on file, and the landlord is coming early tomorrow morning to change the locks.
