Henry: Portrait of a Serial Killer1986

Henry:
If you shoot someone in the head with a .45 every time you kill somebody, it becomes like your fingerprint, see? But if you strangle one, stab another, and one you cut up, and one you don't, then the police don't know what to do. They think you're four different people. What they really want, what makes their job so much easier, is pattern. What they call a modus operandi. That's Latin. Bet you didn't know any Latin, did you kid?

Otis:
Big f***ing deal.

Henry:
What?

Otis:
Nothing.

Henry:
It's like a trail of sh*t, Otis. It's like the blood droppings from a deer you shot, and all they've got to do is follow those droppings, and pretty soon, they're going to find their deer.

Otis:
Why don't you use a gun?

Henry:
You can use a gun. I'm not saying you can't use a gun. Just don't use the same gun twice.
