I knew it was going to be a difficult case because standing at the foot of Julie's bed, I didn't see any obvious things that caused her death. There were no stab wounds. There were no bruising.

I think Mark Jensen's dishonesty and evasiveness and sneakiness came through in that interview, particularly when he was asked about Kelly Labonte.

I was the DA back then in 1998, and I responded to that crime scene. Over the next two or three years, I would take this case to prosecutors' conferences with me. I'd lay out the facts. And the overwhelming response I got was that there's not enough to charge this case out.

In some ways, it's a better case without the letter. It's a cleaner case without the letter. But I said, you know, one of the reasons I want to put this letter in is because this is Julie's voice. And I think this victim deserves to be heard.
