Peggy then called her son, Robert.

It was evening when Robert rang his father's doorbell.

No one answered.

He looked through the front windows and didn't see anything out of the ordinary.

Robert decided if no one was home, it wasn't worth going inside.

So he left.

Another hour passed, but still, no one could get in touch with Chip and Claudia.

Around 7.30 p.m., Claudia's daughter, Laura, decided to visit the house.

Like Robert, she rang the front doorbell, and again, no one answered.

But Laura wasn't satisfied leaving it at that.

She walked around the back of the house.

She saw a few lights on inside.

And that's when she noticed that one of the back windows wasn't just open.

The screen had been meticulously cut.

She stepped forward to get a closer look.

She could just barely see into Chip and Claudia's shared bedroom.

But even in the dim light, she could see something wasn't right.

It wasn't clear to her what had happened or whose blood it was, but it was enough to make her call 911.

Several officers from the Davis Police Department arrived at the scene.

They tried to get into the house, but couldn't gain entry through the front door.
