VAN SUSTEREN: Was an accident or arson? Joining us in New York is Chief Larry Feld and Assistant Chief Tom Magno of the Dix Hills Fire Department. Chief, have you made a determination yet if this is a crime, if this is arson?
CHIEF LARRY FELD, DIX HILLS FIRE DEPARTMENT: Not right now. It is being investigated by the Suffolk County Arson Squad and the Fire Marshal's office.
VAN SUSTEREN: Assistant chief, this seemed to go up in flames so fast. From what I understood, 45 minutes after you arrived you put it out, but what a flame.
ASSISTANT CHIEF TOM MAGNO, DIX HILLS FIRE DEPARTMENT: We were met by a large volume of fire.
VAN SUSTEREN: Any idea, chief, where this fire started in the house?
FELD: The fire was located on the first and second floor, the central part of the house. But it was a good volume fire and intensity when we arrived.
VAN SUSTEREN: When you say first and second floor, do you mean there were two locations where the fire started? What exactly do you mean by that?
FELD: It was just that the total house that was engulfed in flames upon our arrival.
VAN SUSTEREN: Assistant chief, what is this structure? It looks like it is wood.
MAGNO: It was a two-story private dwelling, vinyl siding, a basic construction.
VAN SUSTEREN: Is this a bad fire? Is there anything about the material that it seemed to flame so badly?
MAGNO: I cannot tell you. When we got there we were met with a very intense fire.
VAN SUSTEREN: Chief, what time did the call come in?
FELD: It came at about 4:59 a.m. in the morning.
VAN SUSTEREN: And how long before the trucks were at the site?
FELD: We were on the scene in about five minutes, all volunteers from my department, assisted by five mutually aid companies from the Huntington Township.
VAN SUSTEREN: You got volunteers there that quickly?
FELD: Yes, about five to eight minutes, approximately.
VAN SUSTEREN: When was the last time they had to respond to a fire?
FELD: We actually had a fire Sunday at a playground.
VAN SUSTEREN: Assistant Chief, that sounds amazing that you got those people out there that quickly.
MAGNO: We have been very lucky to have the volunteers we have in our department. They are very committed, and we are very thankful for that.
VAN SUSTEREN: Chief, explain the criminal investigation. What do they do? Can you give us an idea?
FELD: I really cannot comment on the investigation right now. The Suffolk County Arson Squad is going through the phases of testing stuff. And, like I said, it is under investigation by the Suffolk County Arson Squad and the Huntington Town Fire Marshal's offices.
VAN SUSTEREN: I guess I meant what do they do? Do they take samples? I wasn't asking for what they learned, but how they do it.
FELD: My knowledge is that they take some material and take it back to the crime lab, and they test for possible accelerents, if there would be. Like any other fire we call in the arson squad in just to be sure.
VAN SUSTEREN: We should emphasize nobody was hurt.
MAGNO: Thank god that's right. We had one very minor eye injury, and that is all.
VAN SUSTEREN: That is extraordinary when you look at the flames, a $2.4 million mansion, up in flames. I am astounded you got there so quickly. It is amazing. Congratulations. Thank you both.
FELD: Thank you.
MAGNO: Thank you, Greta.
VAN SUSTEREN: 50 Cent and his ex-girlfriend are locked in a bitter battle over the house. How bad is there battle? It is bad.
TMZ.com has video of the former couple screaming at each other on the street Monday afternoon.
(BEGIN VIDEO CLIP)
UNIDENTIFIED MALE: That is 50 Cent right there.
(END VIDEO CLIP)
VAN SUSTEREN: We spoke with TMZ.com's Harvey Levin.
VAN SUSTEREN: Harvey, it's always nice to see you.
HARVEY LEVIN, TMZ.COM: Hi, Greta.
VAN SUSTEREN: I understand 50 Cent is having a little girlfriend- boyfriend problem. What is the story?
LEVIN: It is huge. It is just an incredible story.
50 Cent had a baby with this woman, her name is Shaniqua. And they never got married. They split up. She was getting $25,000 in child support.
And then 50 made a lot of money off of this water product that he had. And she wanted more, and the judge ended up knocking it down to $6,700.
And then it got really bitter, and he was asking for rent from her. She did not want to pay it. They went back to court; they're fighting.
Four days ago, they have a deposition in this case, Greta, and somebody trashes the lawyer's office in the middle of the deposition. It gets so heated. They two of them are in the street. We have this video of the two of them fighting on the street.
And now her house burns down. And she is inside, the kids are inside. People are inside. And they suspect arson. So it is an incredible situation.
VAN SUSTEREN: You say her house burned down. Is it her house? She is suspicious that he is somehow responsible for this?
LEVIN: When I say her house, I mean the house she is living in. It is the house that he wanted her evicted from. And it is the house where he wanted $4,500 in rent from her.
So she is pretty much saying he is the guy who did it. And he is saying--he did not come out and actually say, I did not do it, but he is not in that area right now. He is shooting a movie somewhere else, and he is basically saying I am really horrified by what happened. But she is clearly pointing the finger at him.
VAN SUSTEREN: His own son was in that house when the fire started, right, or when the house was engulfed in flames?
LEVIN: Yes. And I know where you are going on this. It is unfathomable that his son is in the house, that she is in the house--she is the baby-mama. But that is certainly what she seems to be alleging. And the fire department is telling us that they are suspecting arson here.
They're not saying him, they are saying arson.
VAN SUSTEREN: Their relationship--I take it that at some point it was on good terms. Was this a relationship of any great length of time?
LEVIN: Yes, it went on and off for a while. Again, they did have this kid together, but never married. But it was not just a one-night stand, that is for sure. It was a relationship of some substance.
VAN SUSTEREN: And now he is now filming a movie and his mansion burned down. His child is homeless and his girlfriend is pointing the finger at him. That is where we are?
LEVIN: That is pretty much it in a nutshell, Greta. It is a mess.
VAN SUSTEREN: "Mess" is a great word to describe it.
LEVIN: What is interesting, Greta, is that if this shapes up to be a real investigation where they're looking at him, or whatever, it is just an incredible soap opera. Like you say, how could it be that a child is in the house?
In some ways, if they ever do point the finger at him, that is his best defense is only a monster would do something like that.
VAN SUSTEREN: And this is a soap opera--Tmz.com, that is where I have been following it. As always, Harvey, thank you.
LEVIN: Sure, Greta, see you.
