Erin Moriarty

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.

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.

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.

I later sat down with Alvaro Garibay in 2018, five years after Chip and Claudia were killed.

Alvaro was then 22 years old with a full beard.

They thought you were involved.

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.

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?

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.
