Could be a couple of different things.

So the fear of getting caught. Eliminating a witness.

Maybe it was a physical issue where he got scared

The activity is same M.O.

but different weapon altogether now.

the damage to Claudia Gutierrez's body

had to have been somebody that was very close to her.

- Early in the morning, we responded to a call of a body

that was found inside a car in the area of Baseline Road.

Upon arrival, we found that a female had been shot

in the passenger side of the vehicle.

Carmen Miranda, 37-year-old mother,

was killed with a .380-caliber handgun.

The evidence was clear that she matched

the other victims of the Baseline Killer.

Her pants had been pulled down.

that Carmen Miranda was simply washing her car in the afternoon

at a self-service car wash,

and she happened to be on the phone with her boyfriend

when a suspect came up behind her

as she was vacuuming the back-seat area of her car.

She was pushed into the vehicle.

The suspect shot her in the back of the head

There was a junkyard next door to the car wash,

where there was a stationary camera

that had just happened to be pointed toward there,

and we were fortunate this was captured on videotape,

but it was a very old system, and it was very grainy,

but it showed a suspect

wearing a dreadlock fisherman's cap disguise.

The tape wasn't of great quality,

but it appeared that a flash of light in the moment

after she was shoved in the vehicle

was consistent with her being shot at that time.

- For him to be so bold, to approach a person

who's on the telephone with somebody,

to just take her and throw her in the back of the car.

Maybe he was feeling like,

"Nobody can catch me. Nobody can touch me."

the fear really set in

because it had been captured on a surveillance video.

- At that point, the media glommed onto this case.

- Two suspected serial killers on the loose.

- In the city of Phoenix, you could feel it.

It led the evening news. Well, it led all the newscasts.

That was the number-one story.

- The media coined it the "Summer of Fear."

And I think that was probably mild

compared to what was really happening.

- I was 30. I had just moved here.

I was scared. Of course, I was scared.

I think lots of people were just staying in

and changing their behaviors just to stay safe.

- It's scary because of the fact

that they're unable to catch him.

for releasing very little information.

All that residents have been told is to stay alert.

How much information can we provide to the public

to put them at ease while safeguarding the investigation?

and on the news daily, and it starts to get this bigger story.

And I think that's when it turns into a competition,

- So at the end of July, in 2006,

we got a tip from a person named Ron

So we started doing background checks

and found that Sam had actually lived

in an apartment in Mesa, Arizona,

very close to one of the areas

where one of our victims was shot.

The apartment was registered to a person

by the name of Dale Hausner.

So we set up a surveillance on the apartment,

was found inside the apartment

with different types of ammunition,

both for shotguns and for rifles.

Hausner denied ever having anything to do with it.

- Sammy Dieteman sobered up and realized what he had been doing.

He was only involved in the last two or three murders.

So they located him at his house

and then ultimately followed him to a Target store,

where the undercover detectives walked up to him

just in passing to see him up close and personal.

They, in turn, said he's a dead ringer for the composite.

- Mark Goudeau, who had grown up in the south side of Phoenix

in a big family.

He was one of 13 children. His mother was a maid.

His father parked cars at a car dealership lot.

In 1976, Alberta, his mom, died.

Mark was only 12.

- He had a police record.

Several people in his family had police records.

- Only he knows what his first criminal act was.

When he was in high school, he was accused

of a sexual assault with his brother in the '80s

that he was never charged with.

In August of 1989,

he was charged with abducting a woman,

brutally raping and bludgeoning her.

- He went to prison.

He married his wife, Wendy Carr, during that time.

And after 13 years, he was granted parole.

- He was on parole in our target area.

He lived right by where Carmen Miranda

had just been murdered.

Early in the investigation, he was interviewed

by one of our detectives who was going door to door.

And during that interview, he expressed fear

for the suspect being out there.

In addition, when we were trying to determine a list

of possible suspects of people

who had been recently released from sex crimes,

that list didn't include him because, in a plea agreement,

he was convicted of aggravated assault and kidnapping,

not the sex crime.

When the samples of DNA were extracted

from our sexual-assault victims and entered into CODIS,

Mark Goudeau's name did not hit

because DNA collection was not in use

during the beginning of his violent crimes,

and he wasn't in the system.

where she was found shot and killed in her bathtub.

It was a surprise, what she ultimately told us.

- As soon as I saw him on TV, I remembered,

hey, that was Mark, one of my mom's friends.

And then connecting the dots

as that person could have hurt my mom.

- Sophia Nunez's child recalled being at the mall in Tempe,

where serial killer Mark Goudeau was introduced to her,

and she positively identified him as

being one of her mother's "friends."

She thought she was a victim of his.

- I had met him when we went to the mall,

and he seemed like a normal person.

- Mark Goudeau had met Sophia Nunez at a bar somewhere,

and she finds out he does odd jobs.

♪

- Then later on, he did come to my house

to put on a security door for us because he was a handyman,

and my mom thought she was helping somebody

who could use the work.

And I went out to the garage and offered him water.

- DNA on her breast, initially collected at the scenes,

turned out to be a full STR profile on Mark Goudeau,

and we were able to connect Sophia Nunez

to Mark Goudeau through his cellphone.

- The police went back through Sophia Nunez's phone records

and found all these calls from Mark Goudeau.

Now, this was very different

from the M.O. in all the other cases,

which were just sort of grabbing someone off the street.

- There was no forced entry.

Clearly, he was allowed in or walked in.

Why he ended up going there and murdering her

is something we'll never know.

♪

Ultimately, Mark Goudeau

was later charged with all nine murders

and 71 associated felony counts

related to the Baseline Killer series of murders.

In 2011, he went to trial on the murders.

- The prosecutor was so businesslike and methodical.

No emotion. Just stacking this evidence.

- He was found guilty and given nine death sentences

and over 1,700 years in prison.

- One of the things that I can never forget about the trial

is during the sentencing, when the families of victims

are allowed to make victim impact statements.

And Liliana's mother got up,

and she spoke in Spanish and said...

"I wish I could take my hand and stick it inside my chest

and pull my heart out and show it to you."

Holy smokes!

I mean, that just is pure grief.

Pure evil.

♪

- And then when they announced everything, I was happy.

But I wasn't happy because it didn't bring my Sophia back.

He'll probably not die in my lifetime,

but maybe my daughters will see it.

Or my granddaughter.

♪

- Unfortunately, as of today, he still remains in prison...

...whereas our victims and families

have been destroyed

when he should be dead nine times over.

♪

- She's still my Baby Sophia.

I miss her. I miss her so much.

- We didn't save my mom,

but we were able to keep this man off the streets

and away from other people

and also provide justice for the many other victims.

There is peace in it, but we also still want to be able

to call her up and talk to her.

You'll just have to look up and talk to them.

And that's something we have to sit with for the rest of our lives,

is that's something that we have to carry with us.
