I'm a columnist for The Record newspaper in New Jersey and USA TODAY.

Sarah Butler is a 19-year-old college student.

She grew up in Montclair, New Jersey.

But she went away to college,

not very far, at New Jersey City University.

It was only... 10 miles.

Sarah Butler is barely an adult,

Sarah doesn't disappear,

- Sarah Butler grew up not poor, exactly,

but not as affluent as most people think of as Montclair.

She was really into dance.

There was a dance school around the corner from her home.

Dancing and performing herself became her community.

She's the first member of her family to go to college

and she struggles.

She doesn't meet a whole lot of friends in college.

She's also having some money trouble.

And just paying for college is a struggle for her and her family.

NARRATOR: But Sarah sticks it out.

College is important to the Butlers.

Even if school's a struggle, the future is bright.

So there's no good reason for Sarah Butler to go missing.

CHRISTOPHER: November 25th, a friend of Sarah's sister spots the family's minivan.

Sarah' sister and some friends arrive

after the police are already there.

And police are searching the van.

Sarah's sister and friends notice the same red hair that Sarah was wearing

the night that she went out.

That's a very important piece of evidence.

So the parking lot where the van was found is searched by police and a cadaver dog.

They don't find anything.

NARRATOR: The abandoned van and hair proved to police

that something likely did happen to Sarah.

As law enforcement dust the car for fingerprints

and scours what they now believe is a crime scene,

one of Sarah's sisters has an idea.

CHRISTOPHER: Sarah's sister and friends know all of her passwords

to all of her accounts.

So they get into her Facebook, they get into Tagged

NARRATOR: It doesn't take long for them to find a suspect of their own:

a man Sarah went to meet on the day she went missing.

CHRISTOPHER: A man reaches out to her there,

his username is LilYachtRock.

After a very short preliminary hello,

LilYachtRock writes,

"Sex for money?"

And Sarah Butler is taken aback. She says, "Wow."

Then she says, "How much money?"

And they negotiate a little,

and a price is agreed upon. $500.

And she says, "You're not a serial killer, right? lmao."

NARRATOR: Sarah is cautious,

but college is expensive

So she gives LilYachtRock her number

CHRISTOPHER: He tracked and found women using his phone.

He plotted ways to kill them using his phone.

Everything was with his phone.

And what's interesting about this case

is how these women used his tools against him.

NARRATOR: It's like he turned his own phone on himself

and pulled the trigger.

- The murders that he committed,

his cell phone put him at every location.

He never cracked.

No facial expression, no remorse,

no nothing.

But when you have a mountain of evidence

that's pointing in your direction, you know, you can't deny that.

I mean, when they brought the cartons of evidence,

there was... It was so high. [laughs]

You know, there were so many boxes of stuff against him.

You know,

how can you sit there and say it... it wasn't you?

NARRATOR: That mountain of evidence takes three months to present at trial.

But it only takes the jury two hours to determine Wheeler-Weaver's guilt.

WOMAN: As to count one, what is your verdict?

JURY MEMBER: Guilty.

WOMAN: Count two? JURY MEMBER: Guilty.

WOMAN: Count three?

NARRATOR: Guilty... on all 11 counts.

I tried everything I could do to make sure that the people heard me

and that he was gonna be locked up.

Him saying that he still didn't do it

makes me feel like he has no type of remorse about it at all.

On sentencing day

is when I felt the power.

Yeah.

That's when I felt it.

ASHLEY: There's a lot of Black girls that have been missing.

There's a lot of sex workers that have been going missing.

Have he been doing this?

Because don't nobody just wake up today and just wanna just kidnap four people.

He could've done this to many other girls,

and this is all y'all know about.

NARRATOR: The possibility that there are even more women who lost their lives

is haunting.

But the actions of these four young women

and their friends

caught a killer.

CHRISTOPHER: It's absolutely true

that the women who were victims of Wheeler-Weaver

and women who put themselves in the path of becoming his next victim

stopped him.

Without their intervention,

it seems likely that he would've murdered many more women.
