A: Thank you for coming, officer.

B: What seems to be the problem?

A: I was in school all day and came home to a burglarized apartment.

B: Was the door locked when you left?

A: The door was still locked when I came home, so maybe they came in through a window.

B: Do you live here alone?

A: I have a roommate, but she is still at school.

B: Have you seen anyone suspicious in the neighborhood?

A: No, nothing unusual.

B: Well, I am going to check the windows and look for fingerprints. I want you to figure out what is missing.
