    GRETA VAN SUSTEREN, HOST: Francine Tate — she is the third Wisconsin woman to disappear in less than one month. Is a serial killer striking in Wisconsin?

    Now, it all began on June 23. College student Kelly Nolan vanished in college town Madison, and days later, her body was found murdered. On July 13, college student Mahalia Xiong vanished in Green Bay, home to another University of Wisconsin campus. Mahalia had been out bowling with friends. She has not been seen since. And last Tuesday night, Francine Tate left a church prayer meeting in Madison, and now she, too, has simply vanished.

    Ed Miller, correspondent for "America's Most Wanted," joins us. Ed, are the police — I mean, I don't want to jump to conclusions and scare people and say there's a serial killer. We do know a murderer is out there with Kelly Nolan. No one's been arrested. But are the police now suspicious that one person could be responsible for the two disappearances and one murder?

    ED MILLER, "AMERICA'S MOST WANTED": Absolutely. As far as the two college young women, they are comparing notes. We know for a fact that both Green Bay police and Madison police huddling together. However, our police sources at "America's Most Wanted" that are fairly high up and fairly responsible believe that Francine is not part of the equation, that it just doesn't match. Francine doesn't fit into the same kind of pattern.

    VAN SUSTEREN: Francine, though — I mean, you know, I guess that I would not exclude that as a possibility and be sort of dismissive. I mean, she's a rather young-looking 50-year-old woman. She disappeared at night. If you came up behind her, she has long hair, certainly, like Kelly Nolan — I mean, and not particularly far from where Kelly Nolan was nabbed. So I guess I wouldn't be so quick to discount it. Are they completely discounting it?

    MILLER: They are not completely discounting it. But again, our police sources are telling us there's a huge difference with Francine in that she had a couple of issues. One was that she had bouts of depression, that both police and the family have acknowledged that she was battling depression. I'm not saying she was taking medication for it, but she did have these bouts of depression which possibly could explain her mysterious disappearance.

    There's also a question of a man, a homeless man that stayed with them the night before she disappeared. Now, police are not saying that that man is responsible for her disappearance, but it does raise some questions. Again, it takes it sort of out of equation because she just seems to have some other issues involved.

    They did do extensive searching over the weekend for Francine because she had mentioned as she was leaving the Bible class that she might have left something in the park. so she — they thought she might go back to the park to look for it. So they did a lot of searching. No clues, nothing new on Francine.

    There are some new things that we can talk to you about Mahalia, if you like.

    VAN SUSTEREN: Go ahead. Tell me.

    MILLER: Mahalia is young, with the other young college student that disappeared. We do know that police and the family have gone through step by step every single business from that bowling alley back toward her home, looking at surveillance tape. We know that she made a cell phone call at about 2:00 o'clock in the morning, and the ping from that cell phone went to a — you know, a transmitting device about two miles away. So there was some talk that perhaps she had stopped at a gas station, you know, because that's where the beam would be, more or less in that vicinity.

    We now can confirm for you that the surveillance tape shows no sign of her in that gas station or in any other business along the way. We know for a fact that there are surveillance cameras on the bridges as you approach Green Bay, go into town. So she disappeared somewhere between the bowling alley and those bridges. So she had about 15 minutes there where something mysterious happened to her.

    VAN SUSTEREN: How about water? I mean, a lot of viewers have written in and send me e-mail questions wondering if perhaps she drove off the road and into some water. Is there any waterway that's sort of near or adjacent to her normal route?

    MILLER: There is. There is that river that runs along that. And as I mentioned the other night on the air, we did a story that a woman disappeared in San Francisco that they were absolutely convinced was carjacked, and she made a wrong turn in the middle of the night. And she was a physician. She obviously knew she what she was doing. This was not an irresponsible child by any means. And she made a wrong turn and ended up in San Francisco Bay. So that is a possibility.

    The other new little element that we can tell you about Mahalia is that we know now that we can confirm that she was leaving that bowling alley with a bunch of friends. They all got in their cars. And we know she was the last to get into her car. So in other words, they all left in sort of a ragtag caravan going back toward Green Bay, and her car was the last of the lot. So everyone sort of looked over their shoulder. They thought she was behind them, but they're not really sure. They do know she was the last to leave.

    VAN SUSTEREN: Do they know if this phone call to them — I know it went to the boyfriend's brother's cell phone. And I'll explain that with one of my next guests. But do they know that that was a real effort to make a phone call, or could that we what we call "pocket dialing," where you sort of hit the button? I mean, you can even have a struggle, I guess, and hit a phone button and get a redial.

    MILLER: No, they don't know. And you are absolutely right. It could have been a redial. There was some thought at the time that it might have been a distress call. And again, that's why they kind of zeroed in on those surveillance cameras. But again, I've talked to have the family and I've talked to police over and over again. They've looked at all these surveillance camera pictures. And again, they brought the family out, just to make sure that they weren't missing something. There is no sign of that white car, no sign of Mahalia.

    VAN SUSTEREN: Ed, thank you, as always.

    MILLER: Thank you.
