This is a partial transcript from "On the Record," March 8, 2007, that has been edited for clarity.

MARTHA MACCALLUM, GUEST HOST: And tonight, Anna Nicole's autopsy. What really killed her? The police say that they have new evidence, evidence that just may put — that has, in fact, put those autopsies results on hold.

Joining us now is Dr. Joshua Perper, Broward County medical examiner. Doctor, good evening to you. Thank you for being with us tonight.


MACCALLUM: Was your report ready to go? Were you ready to release the results?

PERPER: Yes, I was. And the reason why I decided not to do so is because I was informed that there was some additional evidence, which I want to review before I have my final report. And that's the reason why my press conference is going to be delayed by a week or two.

MACCALLUM: OK. So they told you...

PERPER: It's not — they didn't tell me that they had an investigation, but I'm aware now that there is some additional information, which I have to review. And we review so much information that I don't want to dismiss any kind of additional information which might or might not be helpful.

MACCALLUM: So explain to people, if your tests are done, your results are done, how could this, you know, possible change that most people are interpreting as meaning that the police think there may have been some criminal activity that might have an impact on how you word your report, correct?

PERPER: No. No, not necessarily, because additional information might be important in either reinforcing my prior conclusion or weakening them or changing them. And I don't know what information there is there. It may well be that there's not going to be no change in my determination. So I think that there is a jump in conclusion, which is not — it's not reasonable.

MACCALLUM: All right. Did they give you — I know you don't want to say what your conversation was with them, but they give you an indication — do you know what they're working on?

PERPER: They did — I don't want to go into that, but they did not give me any indication that they are involved in a criminal investigation, no.

MACCALLUM: OK. You know, earlier, you did an interview that we played on my afternoon show, "The Live Desk," and it was about Dr. Kapoor. You said that you had not interviewed Dr. Kapoor, that he was the only person that you had wanted to interview and you did not. We received a response that was written to "The Live Desk," and this is the response from Dr. Kapoor. This is from his attorney. "Dr. Kapoor has been appropriately cautious about protecting the confidentiality of Anna Nicole Smith's medical treatment. It's apparent that such caution is justified when the Broward County medical examiner makes public statements about a supposedly confidential investigation." He also goes on to say that he has — that he will continue to cooperate with any formal requests that come in from authorities.

Do you have any reaction to his statement about your activities?

PERPER: This is absolutely unacceptable because medical examiners receive information from physicians, and they keep this information from physicians confidential. I didn't release any kind of information. As a matter of fact, I didn't release any kind of information except the information from my autopsy. So this is an attempt to clear himself from his failure to cooperate. In other words, he cannot point to any kind of disclosure from medical records, which was done by me or by my office.

MACCALLUM: But you can confirm for us tonight that you did contact him, that you requested to speak with him and that you declined to do so?

PERPER: Absolutely. And I even said to his attorney if he doesn't want to tell me about the medication which he prescribed, I want to know what was the condition of the person, what was the diagnosis. And I wouldn't have disclosed them, but this would have been important information for me to correlate with my findings.

MACCALLUM: All right. Well, we've invited Dr. Kapoor to respond to that tomorrow. And we thank you, Dr. Perper, very much for being with us tonight.

PERPER: You're very welcome.
