My purse got stolen at work.

My purse got stolen at work today. I lost all my credit cards, driver's license, gift cards and about 200$ cash. Also two of my paycheck stubs. I got really upset since I felt I was robbed of my trust in the students. They weren't my students. I was sharing the lab with other two classes. I couldn't imagine how anybody dared to take it when he/she was surrounded by people. I left it on the chair. I told the vice pricipal and the security guard. They looked in trash cans for it but couldn't find it. I even lost my car key.

I hate this. Is there anything I can do or I should do now? I know at least two students were suspects but nobody saw them doing it and I can't accuse them.

I'm really upset.
