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.

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

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.

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?

Daniel would starve himself for extended periods of time, and he regularly talked about death.

And was he taking medications?

Did he talk about what was going on in his head and his thoughts?

Daniel was sent to various therapists, according to Alvaro, and doctors tried to deal with his behavioral and health issues.

In 2012, Daniel told a school guidance counselor that he fantasized about killing people.

The counselor called police, who hospitalized Daniel because of the danger he posed to himself and others.

When Daniel would go through these depressive episodes, writing became an outlet for him.

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.
