O'REILLY: "Factor Follow Up Segment" tonight, O.J. Simpson currently in a Nevada prison serving nine to 33 years for an armed robbery conviction. As we know he beat a murder rap in L.A. but many believed he did indeed kill his former wife Nicole and Ron Goldman back in 1994.

But a new book says Simpson is innocent of those murders. Joining us now from Los Angeles private investigator William Dear, the author of the book, "O.J. Is Innocent And I Can Prove It." So Mr. Dear, you say you have the murder weapon, correct?

WILLIAM DEAR, AUTHOR, "O.J. IS INNOCENT": That's correct. I'm sitting here with it in my lap.

O'REILLY: Hold it up, hold it so we can see it all right. Take the sheath off, police. That -- you say, is the knife that killed Nicole Brown Simpson and Ron Goldman?

DEAR: In all probability, this is the actual knife. You will notice the indentation on the end.

O'REILLY: Ok, now you say in all probability and I mean, I don't know what that means. But let's just stay with the knife. Where did you get the knife?

DEAR: The knife came from my suspect's storage facility.

O'REILLY: Your suspect is O.J. Simpson's son, Jason, correct?

DEAR: That's correct. He was 24 at the time; 5'11," 235 and on probation for assaulting his previous employer with a knife.

O'REILLY: So you went to his storage facility and how did you get the knife?

DEAR: It was put up for sale. We had been watching it. We knew he had items stored in that facility. And so when he failed to pay the rent, we were ready and somebody bought it we bought it back from them. And that's how we acquired the knife. That's why we also acquired the picture of him wearing the knit cap and his diaries and a number of other pieces of information.

O'REILLY: All right. There are a lot of knives in the world. I mean, why are you saying that -- that knife is the murder weapon, why?

DEAR: We had it checked by one of the top experts in the country. And what really makes this so obvious in our mind is the fact that this is a Gerber replica of a Mark 1 which is designed to cut and to kill. The top had been removed and poured wax inside. When you take and compare this to the laceration on the skull of Nicole, you will find that it matches perfectly. On the outside of the sheath --

O'REILLY: Well how do you know that? I mean, you didn't do the autopsy? I mean, how would you know --


O'REILLY: -- that it matches perfectly? I mean, you're -- you're making a leap here but you didn't physically examine the body and you didn't do forensics on the knife. How would you know?

DEAR: We have the crime scene photographs. We took it to two of the experts in fact, one of the experts is the author of "Knife Wounds." And he's considered in gunshot and knife wounds as one of the top experts in the world. He took it up, blew up the pictures took the measurements of the knife and the bottom of the knife compared it to the lacerations on Nicole Simpson's skull and said as far as he's concerned it was the knife.

O'REILLY: All right. But again it's not going to hold up in court. Why don't the Los Angeles police have the knife and why don't they do an investigation based on what you're saying?

I mean, the case is still unsolved. Nobody, you know, legally knows who murdered Nicole Brown Simpson and Ron Goldman. Why aren't the cops taking your knife and then doing all of the forensics necessary to lodge charges against the younger Simpson?

DEAR: Well, in our book, you'll see that we made four attempts to contact them. They were not interested. In 2008 we've met with the attorney general --


O'REILLY: What does that mean they are not interested? They have to be interested. It's their job to be interested.

DEAR: I know. You are absolutely correct.

O'REILLY: Who did you bring it to them, give me a name, give me, give me a name that you brought it to.

DEAR: We wrote to Chief of Police Bernard Parks. We wrote to the district attorney's office. We had the letters that came back to us from them saying that it didn't --

O'REILLY: Maybe they think you are a nut? Or maybe they think you are crazy.

DEAR: Well, if they look at my track record, I hold the world's record as far as the largest number of people arrested and convicted in the history of the United States for a single murder.

O'REILLY: It's hard to believe though that you -- it's hard to believe that you say you have this murder weapon and the Los Angeles Police Department isn't out trying to check your story.

And now you've got a big book out. Do you think this is going to bring them in? Because that's what it hinges on, you give them the knife. They look at the -- at the autopsy. They get in and then you can charge the kid. I'm not going to convict the kid here. The kid is, you know, I don't know what he is doing now.

But it doesn't seem like this is that complicated. If you have a knife and that knife matches the wounds on Goldman and Nicole Brown Simpson, they've got to charge the kid, am I right?

DEAR: I would think so. I -- in fact, I have been doing this for a long time, 45 years. And I would have thought so. Other than the fact that they don't care, they're not interested in bringing this out. They've had enough embarrassment over this case. Look at the socks. If you follow the --

O'REILLY: All right, well we're going to -- we're going to follow the police chief and the attorney general of California and we'll make them care, all right?

DEAR: I appreciate that.

O'REILLY: Listen, I mean, I want justice in this case. And you know, you wrote the book, you can write whatever you want. I don't know if it's true or not. But you have a piece of evidence there and they should be able to match it or not match it. So we'll find out.

All right Mr. Dear, we're going to follow up on this. We're going to do it and we'll let everybody know what happens. Ok? Thanks for coming on.

DEAR: Great.
