GRETA VAN SUSTEREN, FOX NEWS HOST: There are new developments in the so-called "Craigslist Killer" case. Medical student Philip Markoff is already charged with killing on women and attacking another in Boston.

And tonight, more troubles for the doctor want-to-be, this in Rhode Island.

RHODE ISLAND ATTORNEY GENERAL PATRICK LYNCH: This morning in Kent County Superior Court in the state of Rhode Island, a warrant, an arrest warrant was signed by Superior Court Justice Steven Nugent for the arrest of Phillip Markoff, a second-year medical student, date of birth 2/12/86 of 8 Highpoint Circle, Quincy, Massachusetts.

Markoff is wanted in connection with an April 16 going into April 17 incident at the Holiday Inn Express, 901 Jefferson Boulevard, Warwick, Rhode Island.

The arrest warrant is for four counts. Count one is the assault with intent to rob. Count two, assault with a dangerous weapon. Count three, possession of a handgun. Count four is the use of a firearm while committing a crime of violence.

VAN SUSTEREN: Joe Dwinell joins us live, city editor for "The Boston Herald."

Joe it looks that problems are increasing. We've now got Rhode Island to the list. Is there any risk that there any other out there? Are you hearing anything from your sources?

"BOSTON HERALD" CITY EDITOR JOE DWINELL: No, not today.

The last thing that we've heard is that possibly he has up to 16 pairs of women's underwear stuffed under his bed.

So there still could be other victims out there. We just have not heard, Greta.

VAN SUSTEREN: I take it you don't know whether the fiancee has claimed ownership of those, or whether these are victims' underwear.

DWINELL: No, we don't. The fiancee actually sent me an email and said, "That's it. I'm not talking anymore." And, as you know, she has broken off with Phillip, and she is now heading off on her life.

VAN SUSTEREN: So the wedding's off, the engagement is off. She visited him last weekend in jail. She hasn't been back again?

DWINELL: No. Her lawyers told us that that's it. She's not coming back to Boston unless the D.A. asks her to.

So Phillip is now on his own. Even his parents have headed back to upstate New York, and his brother has also left the city. So all of the legal shoes are now dropping into place, and today was times four in Rhode Island.

VAN SUSTEREN: When is he due back in court in Massachusetts?

DWINELL: May 21. I believe that's the date, May 21, here in Boston, on the most serious charges, the murder of Julissa Brisman in the Copley Hotel.

VAN SUSTEREN: And I take it that he will first answer to all his Massachusetts problems before he gets sent off to Rhode Island to answer those?

DWINELL: You're right, Greta. Murder takes precedence in this case, so the most serious charge is that alleged murder of the masseuse in Boston, and that's up top first.

VAN SUSTEREN: And even it were not murder, Massachusetts will not let go of the body. They have got him. They are not going to let go of him until they can at least put him through the system there.

What about his computer? I suspect they have now combed through that computer to see how much chatting he was doing on craigslist, assuming that he is the craigslist killer that they have been looking for.

DWINELL: Right. We haven't heard a lot about the computer. That's a fascinating part of this case that hasn't come out yet. So we have not heard word one about that yet, just a little on the edges.

VAN SUSTEREN: How is he doing in jail? Do you get word on how he's doing?

DWINELL: Not for a little bit. We do know that he's in a paper suit, and then also on top of that, a protective kind of suit that they put on you so don't take your own life. He's under suicide watch. Our sources have told us that the guards are really keeping an eye on him. They do not want him to take his own life.

VAN SUSTEREN: When you look at this guy, and anyone who is in medical school, what a bright future you would have thought that had. And that's a profession, isn't it, where you go into it to save lives.

Boy, it's extraordinary how one person could so ruin other people's lives and his own.

DWINELL: It's a complete mystery. Here you have a second-year medical student. Some people say he was brilliant. Some people say he was weird. This is what you see in these types of cases.

One expert told me it's the mask of sanity. You know, he may appear to be, you know, someone that you admire. But then there is a dark side to him, and that's what we are hearing about, all of these allegations of just a real, cruel, alleged dark side.

VAN SUSTEREN: Indeed, very dark. Joe, thank you, as always.

DWINELL: You're welcome, Greta.
