What is the best thing to do after you have a break in?

I came home today to find my room ransacked and things missing like my computer and TV. I stay in a sleeping room and is on disability so I don't have renter's insurance. I feeling about who done it because there was no sign of forced entry and the building manager is the only one with the key. I'm always paranoid about keeping my door locked and even locked it everytime I left my room even to go to the bathroom. I really don't trust my people and I'm from gulible. I know I'm not getting my things back which hurts because of writing on the computer. Not sure if I printed everything out. What should I do besides filing a report with the police. I'm not vendictive and I believe in Karma and that maybe something good will come out of this. I'm a good person and hopefully this is only a dark shaded area of the big picture.

Call the police and file a report telling them what's missing. You really should have insurance, it's not that expensive (around $10 per month or so) and it's worth it. I learned that after lightening struck my apartment and zapped my computer and all of my phones.
