Criminal Minds, Season 1

Gideon:
Anyone recognize these faces?

Student:
Victims of the Footpath Killer.

Gideon:
That's what Virginia newspapers are calling him. We refer to him as the Unknown Subject or Unsub. I told Virginia P.D. they're looking for a white male in his twenties, who owns an American made truck in disrepair. Works a menial job. I told 'em, when you find him, don't be surprised if he speaks with a severe stutter.

Student:
Not to sound skeptical, but come on... a stutter?

Gideon:
Where'd the murders occur? Hiking paths. Isolated. If I'm a killer who has to use an immediate application of overpowering force, even out in the middle of nowhere, I lack confidence. I can't charm them into my car like Ted Bundy did. I can't because I am ashamed of something.
