A scene from “Unwrapped”

Hawkes: The note paper I found on the vestibule floor is very promising. It took me a while to figure it out, but it's a New York State inmate I.D. number.

Jo: So what's your theory? That the killer jotted down his inmate number and left it behind at the scene of the murder?

Hawkes: Wow, it is a tough crowd today.
