I am pretty sure that he was ruled out or discounted awhile ago. If you goto

So many people ask me if there is any chance that Scott may be involved in Kristin's disappearance. I have decided that now is a good time to let you know what I know and leave it up to you to make up your own mind.[/font]
[font=Arial,Helvetica,sans-serif]
First, regardless of whether or not Scott is involved, one thing is for sure...Paul Flores is definitely involved in the respect that at the very least he knows more than he is saying and he and his family are refusing to cooperate with investigators. This is not a case of either/or. It is more a matter if Paul had any help and if so, was Scott Peterson one of those who helped.[/font]

The common thread here is Cal Poly in San Luis Obispo. All of the main players went to college there at the same time. That includes Kristin, Paul, Laci, Scott as well as Ermelinda Flores (Paul's sister) and Brett MAcArthur - the man Ermelinda eventually married.[/font]

I am not positive that Ermelinda and Brett attended Cal Poly at the same time - but I was told that they were also students.[/font]

After Kristin vanished, investigators covered the campus with a massive interview sweep which included, as I understand it, about 600 letters to students who were living on campus asking if anyone knew anything about Kristin's case.[/font]
[font=Arial,Helvetica,sans-serif]
Scott Peterson was mailed one of those letters but he never responded. That isn't saying all that much though because as it was told to me - a lot of students didn't respond.[/font]

When the bright light of justice began to seriously bore in on Scott, this naturally brought much needed attention to Kristin. San Luis Obispo Sheriff's department did look into the possibility and even called the Smarts wondering if Kristin had ever mentioned Scott.[/font]

Then, rather quickly, San Luis Obispo Sheriff's department made a statement saying that there was no connection to Scott having anything to do with Kristin's case.[/font]
