In 1996, Seattle police faced an unusual challenge.

A severely wounded dog witnessed the murder of his two owners.

Could the dog identify the killers and if so, how?

How?

December 9, 1996, Seattle, Washington.

It was going to be a special day for 22-year-old Raquel Rivera.

She was starting a new job as a receptionist in a downtown office.

I seen her the night before and she was really excited about it.

She was a little sick but she wasn't worried about she was going to make it the work or not.

She was really excited.

Raquel shared this house in Seattle's South Park section with her long-time boyfriend, Jay Johnson.

The two had been together since high school and were talking about getting married.

Just after dawn, neighbors heard gunshots coming from the couple's home.

About four or five shots in a break and then maybe about six more shots.

When police arrived, they found the front door off its hinges.

The windows had been shattered by bullets.

Inside, with two bodies.

Raquel Rivera's mother, who lived only a block away, got the phone call.

Every parent dreads.

When I got there, the police said everybody, they would let me in their apartment.

And I said, it's kind of a Raquel.

The bodies were positively identified as Raquel and Jay.
