Before we begin, just a trigger warning. The following episode contains references to graphic physical violence and suicide. Please listen with care.

11.497 - 21.093 Corporal Allen

23.808 - 56.313 Erin Moriarty

For two months, police have relentlessly searched for the killer of Chip Northup and Claudia Maupin. Officers had interviewed the family and people who knew the couple. They'd set up a hotline to receive tips. But nothing had panned out. And then, late on the evening of June 15, 2013, 911 dispatch received an anonymous call. they transferred it to the Davis Police Department.

0

58.617 - 64.567 Corporal Allen

Okay, what are you calling to report, sir? The double homicide that happened in April this year.

67.912 - 84.473 Erin Moriarty

To determine if the caller was a crank or not, Corporal Scott Allen asked the person to share details about the crime. And then he introduced the caller to Corporal Kirith Bresnik, who knew more about the continuing murder investigation.

84.514 - 95.732 Corporal Scott Allen

Would you mind kind of giving me the details of the information that you have?

95.752 - 100.339 Corporal Allen

Yeah. The person who did it, he told me everything. He told me everything. He did it step by step.

103.289 - 113.046 Erin Moriarty

The caller clearly knew a lot about the murders and had information that the police hadn't shared with the public or even the victim's family.

Chapter 2: What details did the anonymous caller provide about the double homicide?

151.073 - 172.477 Erin Moriarty

But what this caller revealed was beyond anything they had imagined. The person the anonymous caller knew better than anyone else was named Daniel Marsh. He was 15 years old.

0

172.497 - 179.668 Corporal Allen

I think the word is psychotic, basically. He's the kind of person that likes to see something hurt.

0

185.808 - 217.569 Erin Moriarty

I'm 48 Hours correspondent Erin Moriarty, and this is 15 Inside the Daniel Marsh Murders. Episode 3, A Strange Tip. After spending hours on the phone with police, the clearly nervous anonymous caller finally agreed to come down to the police station to talk in person.

0

219.492 - 223.459 Alvaro Garibay

Can I get some water? Yes, please. I just wanted water for that.

0

224.249 - 246.718 Erin Moriarty

The teenage tipster was Alvaro Garibay. He arrived at the station early the following morning. There, police led him into a small room and offered to grab him some snacks. Alvaro was skinny, with long black hair that was pulled up into a ponytail. He wore dark-framed glasses.

247.679 - 258.912 Erin Moriarty

A camera in the room captured Alvaro as he nervously rubbed his hands together and tapped on the table next to him until the officers came back into the room.

260.154 - 267.402 Corporal Kirith Bresnik

How old are you?

267.423 - 273.347 Unknown

I'm 17. We just met. Do you mind spelling the name again? A-L-V-A-R-O.

273.367 - 291.544 Erin Moriarty

At first, investigators weren't sure what to make of Alvaro's phoned-in tip. Given his intimate knowledge of the crime, they had to consider the possibility that he himself could have been involved. So they read him his rights.

Chapter 3: Who is Alvaro Garibay and what role does he play in the investigation?

329.961 - 341.459 Alvaro Garibay

Oh, yeah. I mean, I mean, I retrospect, I totally get it. I mean, I'm like some random kid saying that this person committed a crime. I'm like, you know, kind of freaked out at the time.

0

342.541 - 354.139 Erin Moriarty

The story that he had shared with the police still haunted him. The story of his once close friendship with a teenage boy named Daniel Marsh.

0

356.853 - 360.08 Alvaro Garibay

When I first met him, he was very shy and very quiet.

0

360.14 - 380.067 Erin Moriarty

Alvaro met Daniel in seventh grade at Holmes Junior High School. Both of them were lonely, self-described outcasts who bonded over their mutual love of the heavy metal band Disturbed. Like, we just hung out a lot. What would you do when you'd hang out?

0

380.168 - 395.944 Alvaro Garibay

Just like play video games and then just like watch music videos and go on YouTube. Like watch like the dumbest YouTube videos ever. And we'd just sit there and laugh for like hours. You know, like those like, like, like can't breathe kind of laughing.

395.985 - 420.067 Erin Moriarty

Alvaro said that he and Daniel became fast friends, almost family. Daniel would talk to him about his rocky home life. When Daniel was 10 years old, his parents separated, and his mother had an affair with a woman. When his parents divorced shortly after, Daniel said he felt abandoned.

420.828 - 430.718 Erin Moriarty

Alvaro told me that the situation infuriated Daniel, who over time directed his anger at the woman that his mother was involved with.

430.698 - 445.454 Alvaro Garibay

He hated her. Like, absolutely, like, because he would tell me that I know this woman was involved in my parents' divorce, and I just want to, like, strangle her to death. I remember him saying that to me.

445.874 - 449.198 Erin Moriarty

Did you think he was serious when he talked about wanting to kill her?

Chapter 4: What disturbing interests did Daniel Marsh exhibit as a teenager?

464.893 - 466.24 Alvaro Garibay

Talked about it, yeah.

0

468.717 - 500.761 Erin Moriarty

The conversations disturbed Alvaro, but he remained close with Daniel. In high school, they smoked marijuana together, played guitar, and watched YouTube videos. But eventually, Alvaro said, Daniel started spending hours watching very disturbing content, videos of torture and beheadings. As I warned you earlier, what you're about to hear is disturbing.

0

500.801 - 520.864 Alvaro Garibay

There was this one torture video that really like hit me, that made me feel like more uncomfortable and more unsettled, which was a video of this person drowning somebody. They have like a video of somebody like, you know, like a scarf on their face and just like putting them under a tub and just drowning them.

0

521.333 - 527.441 Erin Moriarty

Alvaro was upset by what he saw, but he said that Daniel seemed to enjoy the videos.

0

528.422 - 535.131 Alvaro Garibay

He just sat there, you know, just kind of like, oh, what's going on? I think, like, fascinated by it.

537.535 - 551.273 Erin Moriarty

When we spoke, Alvaro explained that he thought Daniel's interest in violence and hurting people was just a way to de-stress, not something he'd try to replicate.

552.434 - 558.006 Alvaro Garibay

That's how I took it. I never thought in reality this person was actually gonna go do something about it, you know?

567.79 - 587.122 Erin Moriarty

After Daniel's parents divorced, things became even more tense between Daniel, his parents, and his mother's new partner. According to Alvaro, Daniel, then 14 years old, became fixated with his weight. How thin did he get? I mean, was it really a problem?

587.142 - 592.11 Alvaro Garibay

He got really thin. I think I have a couple photos of him and I hanging out, and he looks like bones now.

Chapter 5: What was Alvaro's reaction to Daniel's confession about the murders?

653.168 - 659.036 Alvaro Garibay

I was like, uh, just stuff. And I was like, oh, okay, like lyrics? And I was like, nope. I was like, oh, okay.

0

659.957 - 679.366 Erin Moriarty

The police had shared with me pages copied from Daniel's personal journal from this time period. And I showed them to Alvaro. You want me to go through this? Yeah, tell me. Because this is like crazy stuff. Well, tell me why you say it's crazy stuff.

0

679.386 - 687.924 Alvaro Garibay

Because it's like, it's just random streams of consciousness. What the hell is this? It's hard to read at all.

0

688.546 - 689.868 Erin Moriarty

It looks like someone with a gun.

0

690.269 - 690.53 Alvaro Garibay

Yeah.

690.871 - 718.048 Erin Moriarty

In his mouth. I pulled out one page that Alvaro had already seen. Daniel himself had shown it to him. The page was covered with drawings of skulls mixed with references to serial killers Ted Bundy and Jeffrey Dahmer and song lyrics about sex and murder. This is kind of scary when you look at it, isn't it?

719.193 - 732.95 Alvaro Garibay

Oh my gosh, like you don't even, okay, so when I first saw this, I didn't think too much about it. Now, I'm like 22, looking at this, it blows my mind that I like didn't even like think about what like could happen.

734.772 - 737.856 Erin Moriarty

Another page was covered in expletives.

739.057 - 743.783 Alvaro Garibay

There's one that's like kill, kill, kill.

Chapter 6: Why did Alvaro hesitate to report Daniel to the police?

785.182 - 800.402 Erin Moriarty

Some of Daniel's journal entries involved his girlfriend. And these ones didn't just talk vaguely about murder. They showed just how seriously Daniel was thinking about killing. Okay.

801.02 - 801.401 Alvaro Garibay

Wow.

802.383 - 802.904 Erin Moriarty

What is that?

0

804.488 - 813.308 Alvaro Garibay

This is him planning to kill her ex-boyfriend. But he keeps writing, I am ready.

817.507 - 852.035 Erin Moriarty

In his original interview with police, Alvaro described the weekend of April 13, 2013. It was the weekend of Alvaro's 17th birthday, the same weekend that Chip and Claudia were murdered. Alvaro spent the time playing video games. He went to Guitar Center with his family. His friend Daniel didn't join him, but he did invite Alvaro to hang out that Sunday to talk about something important.

855.96 - 864.051 Corporal Allen

He said, I want to tell you something important. Yeah, and he told me he had an interesting night and he wanted to talk about it.

865.651 - 873.054 Erin Moriarty

Avro said Daniel wanted to tell him about the interesting night he had had hours earlier.

873.074 - 879.795 Corporal Allen

Like he started off by telling me that he killed two people and then I told him I don't want to hear about it. I want to know about it.

Chapter 7: What led Alvaro to finally call the police about the murders?

927.447 - 929.492 Alvaro Garibay

Oh, okay, well, I'll just talk to you about it later.

0

933.1 - 946.817 Erin Moriarty

Later on, in social studies class, someone told Alvaro about a story they had read in the newspaper. It was about a double homicide that had taken place over the weekend.

0

948.639 - 954.887 Alvaro Garibay

And I was like, oh, snap. All right. And then that's where everything kind of just like turns into a movie.

0

957.31 - 965.636 Erin Moriarty

Alvaro began connecting the dots. Later, he received a text from Daniel to come over to his house.

0

968.68 - 989.221 Alvaro Garibay

And then when I go to his room, like, you know, like, I just walk in. He's sitting on his, you know, rolling chair, you know, by his computer. And I sit on the side of his bed. And then he starts telling me, like, you know, he's like, so I actually did it. And then. I don't like talking about this too much.

989.882 - 993.147 Erin Moriarty

I know, but tell me what you can. Just describe what he told you.

993.368 - 1000.839 Alvaro Garibay

So when he gave me basically, I'd say like a rundown of what he did.

1004.244 - 1028.368 Erin Moriarty

And this is what Daniel told him. that on Saturday, instead of attending Alvaro's birthday celebrations, Daniel had put on all black clothing and a ski mask over his face. He told Alvaro that he had grabbed his mother's six-inch hunting knife and then left his home in the darkness of the night.

1030.37 - 1035.376 Alvaro Garibay

He showed me the knife, the weapon. His shoes?

Chapter 8: How did the police respond to Alvaro's information during the investigation?

1076.131 - 1078.034 Alvaro Garibay

I honestly, I think about that a lot.

0

1078.715 - 1080.277 Erin Moriarty

Did he seem proud of what he had done?

0

1080.617 - 1089.969 Alvaro Garibay

Yeah. Oh, yeah. He seemed very, like, content and, you know, took a lot of, I mean, it sounded like he took a lot of pleasure out of it.

0

1090.329 - 1093.754 Erin Moriarty

Did you get the impression he was kind of bragging to you about what he had just done?

0

1094.114 - 1098.58 Alvaro Garibay

Yeah, he was chuckling. He was laughing about, you know, putting inanimate objects in their body.

1101.766 - 1111.019 Erin Moriarty

The details were so upsetting to Alvaro, so difficult to absorb. He didn't know how to respond to Daniel's story.

1111.039 - 1129.545 Alvaro Garibay

I felt like throwing up. I felt like I couldn't feel anything. I felt very numb. And I just walked out. My head's just running, spinning. And then I'm like looking at the door and I'm like, oh my gosh, like I need to get out of here. And like, I had this feeling that the police were going to break in here. And I'm like, I need to get out of here.
