WOMAN: You've heard
 of the Zodiac Killer.
And you've heard of Son of Sam.
 The Golden State Killer
 was one of the most prolific,
 violent serial rapists,
 and eventually, a murderer.
And the tragedy of this case
to me
is that it's not better known.

PATTON OSWALT: Patton Oswalt,
 sitting here with the lovely,
 and intelligent
 Michelle McNamara, my wife,
 and creator of
 one of the best written,
 and creepiest crime blogs
 on the web.
MICHELLE MCNAMARA:
 I just obsessed over it.
What drives me is the need
to put a face
 on a unknown killer.
 After my husband
 and daughter fell asleep,
 I hunted the killer
 with my laptop.
WOMAN 2: She was doing
 two things at once.
 She was writing a book,
 and she was trying to solve
 a case.
She had material that other
investigators had never seen.
WOMAN 3: She introduced you
 to the lives of the victims
and made you care.
MICHELLE: I had a murder habit,
 and it was bad.
 I would feed it
 for the rest of my life.
OFFICER: I know she never had
 a badge and a gun.
 Michelle always was one of us.
MICHELLE:
 Open the door.
 Show us your face.
 Walk into the light.
