On the island of Aruba, there are four suspects in custody, still no sign of Natalee Holloway. We're going to talk to her mom in a moment, but CNN's Karl Penhaul has been tracking the investigation all weekend. There've been a lot of developments as the father of one suspect has repeatedly been called in for questioning. Let's get the latest from Karl in Aruba.
(BEGIN VIDEOTAPE)
KARL PENHAUL, CNN CORRESPONDENT (voice-over): Suspect Steve Croes covers his face with cuffed hands as police bring him to court. On a judge's orders, he'll be kept in jail for the time being while prosecutors investigate his links, if any, with Natalee Holloway's disappearance.
His ex-wife Janet Croes waits with their 3-year-old son, little Steve. She's anxious but convinced he's innocent.
JANET CROES (through translator): He's a charming person, a very good father and very hard working. I'm 100 percent sure he's not involved in this case.
PENHAUL: Croes was arrested Friday. He's the DJ on this party boat. His boss says he's an able seaman, too, but declined to tell CNN whether the vessel was at sea the night Natalee vanished.
Investigators will not detail how they think Croes may be tied to three other suspects in this case. The chief prosecutor, Caren Janssen, was keeping mum as she left the court.
CAREN JANSSEN, CHIEF PROSECUTOR: I'm sorry. I can't tell you.
PENHAUL: Seventeen-year-old Joran Van Der Sloot, Satish Kalpoe, 18, and his brother Deepak, 21, have not been charge with anything, but under Dutch law, the prosecutor has accused them of murder one, murder two and kidnapping leading to death, to hold them in jail. They were the last people known to have seen Natalee. There's still no conclusive evidence whether Natalee is alive or dead.
Over the weekend, police questioned Paul Van Der Sloot, a judge and father of the suspect Joran Van Der Sloot. Police say they regard him as a possible witness, not a suspect. As he left the police station in downtown Oranjestad, Judge Van Der Sloot was in no mood to talk publicly about what he knows. But Natalee's stepfather, George Twitty, is demanding answers.
GEORGE TWITTY, NATALEE HOLLOWAY'S FATHER: I've met him. I met him the night I got here. I got here, you know, 12 hours after it happened, and the guy's -- he's sickening to me. He's a chicken. You can tell. Why's he running this morning on TV? If he has nothing to hide, why's he running to his car? He's -- he makes my stomach turn.
PENHAUL: It's three weeks since Natalee disappeared, and her parents say they will not leave Aruba until they find out what happened to their daughter.
(END VIDEOTAPE)
PENHAUL: The question many people are asking is why, on an island just 19 miles long and six miles wide, is it taking so long to hunt down clues for Natalee, and why is it taking police so long to check out the stories of these three young men -- Anderson.
COOPER: And Karl, I know a little bit later on in the program, you are actually going to sort of take us through a little bit of the search, kind of show -- try to answer some of those questions about why it is so hard to search on this island. We'll look forward to that report, Karl, a little bit later on 360.
Also coming up, I'm going to talk with Natalee Holloway's mother. She's in Aruba. Hear what she thinks of the investigation and how she's dealing with all of this. Can hardly even imagine how she's doing that.
(COMMERCIAL BREAK)
COOPER: It was there weeks ago today Natalee Holloway was supposed to fly home. Her bags were packed, her passport was waiting, but when they went to the airport, Natalee was not there.
Joining us live from Palm Beach is a woman to whom all our hearts go out, Natalee Holloway's mother, Beth Holloway Twitty. Beth, thanks very much for being with us. Thanks for sparing us some of your time. I can only imagine how it's been for you. How are you doing? How is the rest of your family doing?
BETH HOLLOWAY TWITTY, NATALEE'S MOTHER: It's -- sometimes it's extremely difficult, and then, you know, at other times we're able to stay focused and driven and get some answers. So -- but as you know and everyone who is experiencing it, it is frustrating and it's very difficult. COOPER: Yeah, and it's got to come in waves. A fourth person is in custody, this guy Steve Croes. Do you believe that police are at this point any closer to finding your daughter?
TWITTY: Well, I'm not sure how much information Steve Croes has, and I'll be anxious to find out once that is disclosed. But I do feel that, you know, they are making progress in it, and, you know, just one step closer. Still frustrated, because I don't have answers, but I do feel we are slowly getting one step closer.
COOPER: How much are they in communication with you, the authorities down there? I mean, because publicly they are not saying anything, and I can understand why that may be, but to you privately, I mean, do you feel like you are having good communication?
TWITTY: I do now, yes. I do at this point.
COOPER: Police have questioned the father of one of the suspects, this guy, Judge Paul Van Der Sloot, twice over the weekend. Your husband, Natalee's stepdad, said that Van Der Sloot is acting like he could be hiding something. How do you think he might be connected in all of this?
TWITTY: I think he could be very, very instrumental in helping us find the answers to what happened to Natalee, and I think it is a good idea that he has been questioned.
COOPER: Do you think he learned something directly from his son, or do you think he overheard something?
TWITTY: You know, just from Jug and I, just our intuition, and when we arrived on the island and his attitude, I mean, we felt from the very beginning, as early as May 31st, between the hours of 1:00 and 3:00 a.m., that he could very well be instrumental and have some information.
COOPER: So you met with him pretty soon after you got on the island?
TWITTY: Yes, Jug did.
COOPER: Jug did. And what was -- I mean, what was his -- what about the way he was acting, what about what he was saying that raised suspicions?
TWITTY: Well, I really -- I really can't disclose that, since most of my information was, you know, obtained -- most of it was secondhand. I did have one brief encounter with him that I would not like to comment on, but, you know, it just raised a huge, huge suspicion in Jug and I, at the moment -- from the time we met him.
COOPER: Is -- I understand there is a group of volunteers from Texas, that's coming down to search for Natalee. I mean, what is your sense -- how many people are on the police force down there in Aruba? Do they need more help? I mean, do you need people coming down there?
TWITTY: You know, I'm not going to comment on whether we need more help, but we have certainly not turned any down. We have been so graciously accepting anyone's help, so.
COOPER: And where -- I mean, is there an area right now that you are most interested in looking at, or is there one piece of information or one person you most want to hear from or, you know, where you are kind of focusing your energies on?
TWITTY: I mean, not particularly. We feel like we've exhausted a lot of areas just through family searches and just through the searches by the authorities. So, you know, we really don't have any areas right now to concentrate on, no. We need some answers from those individuals that they have in custody.
COOPER: Let's hope that happens soon. Beth Holloway Twitty, again, our hearts go out to you, and we think of you always. Thanks for being with us.
TWITTY: Thank you so much for having me.
COOPER: All right, you take care now.
Charming?? Those are the one's to watch out for!! Why then is he her ex-husband?
After reading how Natalee's stepfather, Jug, and Beth feel about daddy van der sloot, I wouldn't be surprised if he was arrested next. I hope so. The man isn't acting normal and obviously knows something.
