Lieutenant Disher: Well, there was an extra set of keys in the desk out front. Which wasn't locked. Somebody could've lifted them and made a copy.
Dr. Kroger: Wait, wait, you're saying one of my patients?
Captain Stottlemeyer: To be honest with you, Doc, that's how it looks. We figure somebody broke in, looking for a file. Probably his own file. Look, I realize that you're reluctant here, but I happen to be a homicide detective, and this happens to be a homicide investigation.
Dr. Kroger: I- I understand.
Captain Stottlemeyer: I truly hope you do, because if you do know something... If you believe one of your patients could be involved in this, you are legally obligated to help us out here. Go on, ask your lawyer. He'll tell you. [Kroger's lawyer nods]
Dr. Kroger: All right. There is one patient. He's delusional, borderline schizophrenic. He always thought that I was talking to his ex-wife behind his back. He wanted to see his file to prove that I wasn't lying. Of course I refused. He threatened me. He- He threatened to break into my office. I didn't think he meant it. What have I done?
