GRETA VAN SUSTEREN, FOX NEWS HOST: Now, the last time the JonBenet Ramsey case shocked the headlines, it was thanks to John Mark Karr. Now, John Mark Karr was arrested in August of 2006 in Thailand after confessing to JonBenet's murder, and this was amid a spectacular media frenzy, including TV cameras on board his flight to the United States. The Boulder DA had flown John Mark Karr back to the U.S. and Karr was eventually released after his DNA did not match DNA found at the crime scene. John Mark Karr joins us live.

Nice to see you, John Mark.

JOHN MARK KARR, FORMER SUSPECT IN JONBENET RAMSEY MURDER: Nice to see you, Greta. Thanks for having me.

VAN SUSTEREN: So what do you think about today's announcement that -- a formal letter to John Ramsey that his family has been cleared?

KARR: Very pleased. I think that it should have been something that should have been done almost 12 years ago, and certainly two years ago, when I was arrested. But I'm extremely pleased that someone like District Attorney Lacy would acknowledge once and for all that this family and any members of this family is not responsible for their daughter's death, and their sister's death. It's just this should have happened a long time ago. I'm very pleased with that. It's a wonderful day that we can acknowledge that this family is innocent. They're wonderful people and they should never have suffered like they did.

Watch Greta's interview with John Mark Karr

VAN SUSTEREN: You know, John Mark, you and I have had an unusual -- we've done interviews a couple of times, and you know, it's always been sort of unusual in that I keep telling you I don't think you did it, but you keep dropping hints that you're the one who did do it. Now, your DNA wasn't found at the scene. That doesn't necessarily mean anything. But did you murder her?

KARR: Well, I'm not here to answer questions like that. I've already answered that question over and over, and I don't rescind anything that I've said in the past.

VAN SUSTEREN: But you've never said yes or no to me. I've never gotten a yes or a no out of you. And I just sort of want to -- you know, if I can just figure it out because that'll give me at least some sort of direction where I should go with the next question.

KARR: Well, you know, I don't think that's a yes or no question, Greta. If it was, then I would say yes or no. I don't think that I've said yes or no in 2006, did I?

VAN SUSTEREN: I -- certainly not to me.

KARR: And I don't think that I ever have.

VAN SUSTEREN: Can you explain -- most people deny crimes when they're accused of them, you know, innocent and guilty ones. A lot of them deny it. You don't deny it, though, do you?

KARR: That's -- I don't think that's true that most people deny things that they've done, that they take responsibility for. There are a lot of people who take responsibility for their past actions. That's not true that most people deny things. If a person takes that responsibility, then that's what they do. I'm not the only person who's taken responsibility for my actions.

VAN SUSTEREN: Do you think that the D.A. should arrest you?

KARR: I think the D.A. already arrested me.


KARR: And I think that...

VAN SUSTEREN: Do you think she should again?

KARR: I think that the DA needs to do what they feel is right. I'm not here to talk about -- you know, I think the news today is that the Ramsey family has been granted at least some degree of closure, not complete closure at all, but I think that it's very important that someone like Mary Lacy, who is the district attorney in Boulder, would acknowledge that they are innocent.

VAN SUSTEREN: Is the reason...

KARR: It should have been done a long time ago. That's what the news was today. The news today has nothing to do with DNA. The news today is that there is someone in Boulder, Colorado, named Mary Lacy who's a district attorney who finally, after almost 12 years, acknowledges that this family is innocent.

VAN SUSTEREN: Is the reason, John Mark...

KARR: And they are and they always have been.

VAN SUSTEREN: Is the reason, John Mark, that you were arrested is because you had written something to someone indicating intimate knowledge about something with the crime that nobody else knew except for the person who did it? Is that what got you arrested?

KARR: Yes, that's my understanding. Absolutely.

VAN SUSTEREN: Well, now, that's odd. I mean, it's odd that you would have this intimate knowledge. It's odd that your DNA is not there. It's odd that you won't say yes or no. I mean, there are a lot of -- I mean, this is a very peculiar situation with you.

KARR: I just think that there's a time and a place to say yes and no, and I don't think that that question -- first of all, I think it's a -- it's a very -- it's a question that doesn't have a yes or no answer. I answered as best I could in 2006 in front of probably 150 cameras.

VAN SUSTEREN: Indeed, there were a lot of cameras.

KARR: I don't see any reason that I have to do that again because I'm telling you I'm not rescinding what I said. But I think the important thing here is that this is a process, and whatever process the district attorney sees appropriate to take, then that's what they're going to take.

VAN SUSTEREN: All right. John Mark Karr, thank you for joining us, and good luck. And it's always nice to see you. Glad you came back. And sooner or later, this case will be solved. Thank you, John Mark.

KARR: Thank you.
