GRETA VAN SUSTEREN, FOX NEWS HOST: Thursday, December 11, the day the toddler's bagged body was found, investigators went back to the house of Cindy and George Anthony. They remained there late into the night. What were investigators looking for?

Forensic pathologist Dr. Michael Baden joins us live. And Dr. Baden, before we go into what they might be looking for, as Geraldo just noticed, your wife has recently joined the defense team?


VAN SUSTEREN: What's her assignment on this team?

BADEN: She's going to assist Jose Baez in the whole trial, and she -- her special expertise is in forensic evidence.

VAN SUSTEREN: All right. And I actually know Linda, so we're not going to get anything out of you on this with the attorney-client privilege, so I'm not even going to go there.

All right, now, they went back after discovering this skull in this plastic bag. Why'd they go back?

BADEN: Well, the two obvious reasons would be that they -- to see if there's any other plastic bags that would be related to this one. When a plastic bag is taken out of a container, it has certain markings on it that would relate it to other plastic bags in that container.

VAN SUSTEREN: So they go into the house to see if -- they'll pull every plastic bags container...

BADEN: Right.

VAN SUSTEREN: ... Out of the house that there might be, in case there's -- it's left over, if it was on a roll, for instance.

BADEN: If it was on a roll or because when they tear it apart, the edges can be like fingerprints. But they should have done this six months ago. Hopefully, they did that six months ago.

VAN SUSTEREN: But they wouldn't have known that she was wrapped in a bag, assuming this is Caylee. We're making that assumptions.

BADEN: But if they think that maybe there was a murder in that household, was the reason they went to get evidence, normally, they would take the vacuum cleaner that would have the evidence in it, which they went back and they took now. Normally, they would take duct tape and plastic bags because those could be used in getting rid of a body. Now, the duct tape also that was described contains a load of evidence. The duct tape has a sticky surface that keeps fingerprints, hairs and fibers, other evidence for years against whatever surface it is. And we've had bodies three years later in snow in the Adirondacks and all that not only had fingerprints but had bite marks on it when they bit off the -- the -- and tore the duct tape.

VAN SUSTEREN: You know, it's sort of interesting. We went into the home and we sprayed it with -- I mean, we shot everything we saw inside. I even have pictures of the cats and the dogs. I want to go back and look at our pictures, see if...

BADEN: Right.

VAN SUSTEREN: We were in the bedroom, see if there's a roll of plastic there. I mean, those are the type of things that I assume the investigators would go back and look at even photographs they shot...


VAN SUSTEREN: ... So see if there's anything there.

BADEN: And there may be other things that they found in the plastic bag that we don't know about that they want to connect up.

VAN SUSTEREN: And of course, the analysis -- do you find it unusual that the defense was not allowed to go in and watch this autopsy?

BADEN: I think it is unusual, maybe not for Florida, but for the rest of the country. In 40 years or so doing this, if the defense, when we do an official autopsy, wants to be there, it's to our advantage to be there. They're there, they're looking. We ask if they want -- Do you agree with everything? What don't you agree with? And we straighten everything out at the autopsy table. Whereas in this instance, if the autopsy is done three weeks from now, after they've identified the body, maybe Dr. Smits (ph) will find things that -- who's been asked to come down there -- that the first person missed, that if he were there, they would have all straightened it out together.

VAN SUSTEREN: All right. We have 10 seconds left. I would expect this autopsy would be videotaped anyway and handed over to the defense. I realize that's not as good as being there, but videotape?

BADEN: It should be, but they already brought up an issue that in Florida, they don't give out photographs because -- which I think is bizarre. It should be videotaped, it should be photographed, all that turned over to the defense. But it's more important that the experts be there...

VAN SUSTEREN: To see it themselves.

BADEN: It's better than photographs.

VAN SUSTEREN: Got it. Dr. Baden, if you'll stand by?

Up next: Caylee Anthony's grandparents go "On the Record." Cindy and George Anthony tell you about that heart-stopping moment, that moment they say they first realized their granddaughter was missing. You will hear the frantic 911 call when Caylee's grandmother first told police the toddler, her granddaughter, was gone.
