:40:01
- Bruises?
- No, they're burn marks.
:40:04
We've got them here too
on our female from Dayton.
:40:06
And these marks relate to the marks
found on Fulcher and Speck how?
:40:10
They don't. There were no burn marks
on Speck, Fulcher or Starkey.
:40:13
And we have no slash-circles
here on these bodies.
:40:16
Right.
:40:18
My office, as soon as someone
finds something useful.
:40:28
No luck on
the behavioural specialists.
:40:30
I do have a couple other leads
that I'm following up on.
:40:34
- I'm hopeful they're gonna pan out.
- Great, thank you.
:40:38
A professor of criminal biology,
Professor Daitz, just called.
:40:44
He says he's got time
for you on Saturday.
:40:48
Thank you, Katie.
:40:50
I was operating under the assumption
that O'Ryan was somebody's fantasy.
:40:55
Oh, no, he's real.
He was a student of mine.
:40:57
That fax you sent me,
this circle with the slash through it?
:41:01
That's his construct, his theory.
:41:03
He called it "Suspect Zero. "
:41:06
Suspect Zero?
:41:09
He posited a theory
that a serial killer...
:41:12
...could cross the entire country
without ever getting caught.
:41:16
What makes a killer catch able?
:41:17
Patterns, repetition of behaviour.
:41:19
He imagined someone
with no patterns...
:41:21
...no telltale fetishes, no rituals...
:41:23
...just a random killing machine
that never leaves a clue.
:41:27
But a serial killer by definition
is condemned to repetition.
:41:30
I mean, isn't that
what he's all about?
:41:33
Well, he is until he isn't.
:41:35
And this Suspect Zero, is that
something that you believe in, doctor?
:41:39
It's something O'Ryan believed in.
:41:41
He swore guys like that existed,
only we couldn't see them...
:41:44
...because they didn't obey
the usual laws, like cancer doesn't...
:41:48
...or the HIV virus that
tricks your immune system...
:41:51
...into thinking it isn't there.
:41:53
So you're saying a guy
like that could exist?
:41:55
Do you know the definition
of a black hole?
:41:58
Not precisely, no.
:41:59
It's a celestial body
with a gravitational force so strong...
