:52:00
It's a hybrid life form.
:52:04
A bug-born fungus.
:52:06
It's a variety
we haven't seen before.
:52:10
This is a kind of mite.
And these spores attach themselves.
:52:14
So you're saying mites
carry the fungus to the brain?
:52:18
Exactly. These insects seek out
the body warmth of living organisms.
:52:21
They'll find a host...
:52:24
...especially in small,
contained spaces.
:52:27
That's why the killer shot the fungus
into the a/c units. Very smart.
:52:31
The mites enter through the nose...
:52:33
...find their way up to the warm
brain and embed themselves.
:52:37
The victim doesn't feel a thing.
:52:39
But were you able
to establish cause of death?
:52:44
Yes and no.
:52:46
We found high amounts of serotonin...
:52:48
...and dopamine in the victims' blood.
:52:50
What's dopamine?
:52:53
A naturally occurring chemical.
:52:55
Same as morphine.
:52:56
How much is "high"?
:52:58
- Are those elements toxic?
- Not usually.
:53:00
Just the opposite, in fact.
:53:02
It's considered to be healing.
:53:04
The amount in the victims' blood
is about 50,000 times...
:53:07
...any previously recorded count.
:53:10
To secrete this amount, you'd
have to do a ton of cocaine...
:53:14
...and then have an orgasm
that lasts 40 years.
:53:17
What a way to go.
:53:20
So you're saying the dopamine...
:53:24
...made the victims feel
like they were drowning...
:53:27
...or being consumed by fire?
:53:30
Well, it could. Just like what
drugs do to the brain.
:53:34
- Why different hallucinations?
- Yeah, why?
:53:38
Do you mean the killer
can control their delusions?
:53:45
Actually, we don't know.
:53:47
None of this has ever been studied.
