Patty Scoville

But it turned out much of the evidence was badly contaminated by the only witness to the crime, Jennifer's cat, Mr. Binks.

It took the lab quite a while to actually differentiate between the cat hair, human hair, any kind of fibers.

Did the evidence collected point to any specific suspect?

I mean, you obviously have circumstantial evidence that would lead you to believe it was somebody who she knew.

With that in mind, investigators focused on the two men who fit that description best, Ralph Sepulveda and Brian Travers.

In fact, they needed to know a lot more because it turned out Travers wasn't just Jennifer Servo's coworker.

Travers was with Jennifer just hours before the time investigators determined she was murdered.

Brian said they worked a late shift together, made the decision that they were going to go to Walmart.

Seen here on this security video, it would be Jennifer's final appearance on camera.

Did you drop her off at home?

Jennifer returned home shortly after midnight.

Sometime after that, police believe, Jennifer opened her door to a killer.

Who do you think killed your daughter?

Ralph Sepulveda.

Why do you think he did it?

I think he was a jealous, bitter person.

If he couldn't have her, nobody could.

While investigators lacked the evidence to reach the same conclusion, they did discover a stunning reason to move Sepulveda to the top of their list of suspects.

Meaning?

She told you that?
