Erin Moriarty

Authorities finally had a suspect in Chip Northup and Claudia Maupin's murders.

And with physical evidence, DNA samples, and a complete confession, it seemed like the case against Daniel was solid.

But the fact that the suspect was a teenager would complicate things for the prosecution.

I'm 48 Hours correspondent Erin Moriarty.

This is 15 Inside the Daniel Marsh Murders.

Episode 5, A Killer's Mind.

Victoria Heard had finally gotten the call she had been anxiously waiting for.

I just remember shaking my head, going, what?

What?

That anyone could kill her mother and stepfather was difficult enough to believe, but a 15-year-old?

A teenager?

Who was this boy named Daniel Marsh?

But Victoria would have to wait even longer to see him.

Because Daniel was a minor, his face was hidden by a wall at the arraignment.

Finally, she saw Daniel's face through a TV monitor.

Daniel's father is Bill Marsh.

We spoke in 2018.

Did it ever hurt you that your own son could be involved in something like that?

You never saw any sign of that?

Bill seemed to still struggle with what his son was accused of.
