Okay.

Special Agent Campion asked Daniel to remove his boots.

Then he again asked Daniel about the elderly couple who had lived near his father.

Daniel said that he had been to Chip and Claudia's house once when his father first moved to the community.

It was just a, quote, welcome thing.

Neighbors, meeting neighbors.

But it turned out that Daniel knew quite a lot about Chip and Claudia's home.

He had actually been invited inside with his father two years earlier.

As another officer began opening the DNA swab packaging, Campion picked up Daniel's boots and began probing for more information.

Backed into a corner, Daniel Marsh seemed to see that he was trapped.

Daniel admitted to Special Agent Campion that he had spent years thinking about killing people and that he made it a reality on that April night.

Daniel said he had walked through his father's South Davis neighborhood in the middle of the night.

He scouted most of the street and checked out 50 homes.

Everyone had done a good job of locking their doors and closing their windows until I got home.

When he got to Chip and Claudia's home, he noticed that they had left a back window open.

So he cut the screen and climbed through.

He said at that point, Claudia woke up.

I just started standing over and over.

And he didn't stop.

Daniel Marsh stabbed both Chip and Claudia a combined 128 times.
