Hi, 48 hours listeners. It's me, Aaron Moriarty. This week, we're doing something a little different in your 48 hours podcast feed. I'm taking you inside one of the most chilling cases I've ever covered. The brutal murders of Claudia and Chip Moppin, a beloved couple in their golden years who were killed inside their home

in Davis, California. For months, investigators had almost nothing to go on. No physical evidence,

no clear suspect. They even had to look closely at members of the family.

And then a tip led them somewhere almost no one expected to a 15-year-old boy. It's the focus of my latest six-episode podcast, 15, inside the Daniel Marsh murders.

All week long, you'll hear 15 right here in place of your regular 48 hours episodes.

You don't have to do a thing.

Just keep listening every day this week.

Thank you for being such loyal 48 hours listeners, and I hope you'll join me for 15.

Went to their bedroom. I opened the door.

They just kind of stood over their bed watching them sleep for a few minutes.

My body was trembling. I was nervous but excited and exhilarated.

I was actually going to do it. I was there.

It's finally happening.

I will never understand how he did what he did.

My name is Victoria Heard, and Claudia was my mother. I'm her eldest daughter. My mom was my best friend.

In 1995, Claudia Moppin packed up her bags and left her home in Fairfield, California,

to move 30 miles northeast to Davis.

In her late 50s, she was looking to start a new life.

She had been single for a while, and she had decided that she was ready to settle down.

When I talked to Claudia's daughter, Victoria, she was sitting with her own daughter,

and they couldn't stop giggling as they recounted the move.

I remember very well.
