Grimm, Season 1

Hank:
What about the wounds on his neck?

Nick:
Well It could be vampires, or someone who wants to be a vampire. Or somebody who wants to get a lot of blood fast. These are about the size of an IV needle. My hope, it's an IV. Okay. So, how does a kid get stuck in the neck with an IV needle and end up in a river going over a waterfall?

Dr. Harper:
I saw a lot of this sort of stuff in the late 80's. When the Satanic cults were all the rage. But not lately. Maybe they're making a comeback.

Hank:
So, what killed him?

Dr. Harper:
Oh, he drowned. But my guess is he drowned because he was incredibly weak from loss of blood.

Hank:
So, was it an accident or a homicide?

Nick:
Nobody puts IV needles in their neck by accident.
