JOHN GIBSON, CO-HOST: Breaking new developments in the abroad murder case. In Italy, a fourth suspect has just been arrested for the stabbing death of a British student who police say was killed after refusing to take part in some sort of extreme sex game. A bloody fingerprint led police to him, this as one of the other three suspects in custody is released from jail, but not the American student, Amanda Knox, also known as Foxy Knoxy. "Big Story" correspondent Douglas Kennedy has been reporting on this story from the start. He has brand new details for us. Douglas.
DOUGLAS KENNEDY, "BIG STORY," CORRESPONDENT: Yes, John, this is allegedly Amanda Knox's drug dealer, and Italian police say he has been on the run since the night of murder. He is yet another character in the case that already has several suspects.
KENNEDY (voice-over): Police say she was murdered after refusing group sex. Today, the facts are the same but the group has gotten bigger.
HEIDI NAEGEL, GERMANY POLICE OFFICER (though male translator): This morning, they arrested a 20-year-old man, as a fare dodger, caught without a ticket, was under suspicion of possibly having participated in the murder case in Italy.
KENNEDY (voice-over): Italian police are announced the arrest of Rudy Herman Guede, an Ivory Coast national, seen here in a bizarre video he posted on the internet nine months ago.
And just a few hours later, the police in Perugia release nightclub owner, Patrick Lumumba, saying there was no evidence to link him to the murder of 21-yead-old British student Meredith Kercher. Police say Kercher had her throat slit on November 2nd after opting out of sex games in the Perugian apartment she shared with 20-year-old college Washington State College student Amanda Knox.
Knox has a sweet American face but according to Italian police, a cold heart and is still considered a suspect. Police say it was Knox's word that originally linked Lumumba to the crime, quoting her as saying "Patrick and Meredith were in Meredith's room while I stayed in the kitchen. I can't remember how long they were together in the room but I can only say that at a certain point I heard Meredith screaming and I was scared. So I covered my ears. After that, I don't remember everything. My head is very confused. Police found DNA from both Knox and Kercher on a knife discovered in the apartment of Knox's Italian boyfriend, Rafael Sollecito. Knox and Sollecito remain in prison in Perugia though Sollecito's father hailed the new arrest as great news.
What you can say about the fourth man?
FRANCESCO SOLLECITO, FATHER OF RAFAEL SOLLECITO (through translator): It's time we start speaking in a more precise manner, the only person man.
KENNEDY: Police has described Guede as a Perugia drug dealer who supplied Knox with the hashish she allegedly smoked on the night of the murder. They say he has been on the run in Germany ever since, finally catching up with him when he jump a turnstile at a train station near Frankfurt.
ARTURO DE FELICE, PERUGIA, ITALY POLICE CHIEF (through translator): In the early hours of the day, this young man has been found, and our German colleagues alerted and ,previously in contact with us, arrested him.
KENNEDY: Well, Knox and Sollecito maintained they are innocent. Meanwhile, police say a bloody fingerprint on Kercher's pillow led then to the alleged drug dealer. They say he should be extradited back to Italy in the next few days. It is another twist, John and Martha, in a very already twisted case.
GIBSON: It really is. Extreme sex murder. This new suspect has been arrested. One was released. How does this affect the American's case, that's foxy Knoxy?
KENNEDY: Yea, you know, it's a — it's a perfect great question, because you have the other suspect's father saying absolutely this is the guy, this is the guy that actually did it. This is the one and only suspect, but you have to remember Knox was the one who pointed the finger at Lumumba in the first place. She said he was there, and if he is completely innocent, then her credibility is once again thrown into question.
GIBSON: All right. Douglas Kennedy. Douglas, as always, thank you.
