Patty Scoville

Initially, Sepulveda cooperated with investigators, consenting to interviews, searches, and DNA sampling.

But that didn't last long.

Would not take a polygraph.

Later on, subsequent interviews, he refused to talk to us as the investigation proceeded.

Why was he never arrested for the murder?

It's been more than six years since the murder of Jennifer Serval, but this case is far from closed.

Of all the people you looked at as possible suspects, have all of them been cleared today?

No, they haven't.

The people you had as suspects five years ago remain suspects?

Pretty much.

Investigators say neither man has any history of criminal activity.

In 2005, Brian Travers relocated to Chattanooga, Tennessee.

Ralph Sepulveda re-enlisted in the Army and served a one-year tour in Kuwait.

Now living in Tacoma, Washington, he is currently stationed here as an environmental science officer.

He has declined our requests for an interview.

We owe it to the city, Jennifer's family, and ourselves to find out who did this.

Jennifer Servo was a young girl with a big dream, a dream shared by everyone who knew her.

Now, all they can share are the thoughts of what might have been.

And she was determined to make her dream come true.

Never giving up, it's a powerful conviction for families of crime victims.
