Fingerprints, hairs or anything . No. Did one man have a motive . Without proof, how could anyone convince a jury. Could anyone solve the mystery . Hello and welcome to dateline. When someone goes missing, one of the hardest things for those left behind are understanding was it voluntary or foul play. The truth about what really may have happened may have been the hardest thing of all. Here is more. The key was waiting for them under the matt. That evening outside their moms house, silence. No one home. Where was she . She was always there on time to pick them up from their dads place. This night, dad had to drive them. Across the middle, stopped. What was this . Once we took a few more steps in, we realized something was wrong. This was the moment, the defining one. Nothing the same after this. There was a lot of blood everywhere. We just dropped our stuff and split throughout the house. Con ray was 15, Little Sisters 14 and savannah 10. Three kids trying to make sense of a frightening scene. My mom keeps it completely pick and span. Nothing is ever out of order. Where the desk was, you could see there were papers scattered around. Drawers were ripped open. You went into the bedroom . That was the first place my sister went. She quickly called us there, we followed her. There was blood on the ground. Her moms bed, it was made. It was kind of haphazardly made. She would have done it a different way. By that point, you were pretty upset. What scared me most was that wed find her somewhere in the house. They did not. No debbie hawk. Not anywhere. There was some drag marks, smear marks leading out to the garage where they stopped. Her van was gone too. My initial reaction was my god what could have happened, who could have done this. They ran to a neighbors house. They called 911. We went to my moms room, the bathroom. There was blood. After the shock. I thought, lets not over reability. Clearly, she cut herself with a knife or something and drove herself to the hospital. Where was debbie hawk and what happened to her . What happened to the sacred bond that once held three children together. Back in the beginning, even the police were confused. This case was very unusual from the start. This one did not smell right at all. It appeared she was drug out of the house. Whatever happened here was planned. It looked like a staged crime scene. Had somebody been trying to make it look like she had been kidnapped or just an intention to look like she left home. The bed was made. Most crooks dont do that. And had the perpetrator been looking for something. There was paper scattered. And this financial document was on top. What was significant were the sounds neighbors heard overnight. Several neighbors heard a loud scream. It was a blood curdling type. Why didnt anyone call 911 . That was not the neighborhood bad things happen in. Debbie was an accomplished woman successful. Very popular. She was very reegle and to us royalty. She fitted the bill of princess. She should have been aiken di. That is why the ribbons put up were royal purple. By then, the whole town new about the disappearance. Something else too. Two days after, there was a find. It wasnt good but it wasnt debbie. Police found her van parked on the street in a highcrime area. The drug samples she kept for nasal allergies were gone. The keys left in. Windows down. The backseat covered in blood. At that point, whoever drove would have been a suspect. We are interrupting normal programming this hour because we are following the president in seoul, south korea. We expect him to arrive here 6 08 local time, 5 08 eastern aim. We are looking at pictures of marine one. Arriving and here to address u. S. Military at a location, which when we have a wider shot, you can see is flanked by various planes. Very dramatic location he likes to be in with the American Flag in the background. What do we expect the president to say here as he makes his way to the podium . I expect he will make a brief topper. He may have more time to have more sound there. President trump is very attuned to have the media consume his content. Hell likely tell them how hes rebuilt the military. This is standard fare. Hell probably do a tour. He tends not to use notes in front of the military. He may invite some soldiers on stage to tell some stories. That is the back drop he favors with marine one in the background. Hell address the troops and get back on the plane, the 747. Hell head on home and will probably have to stop for some gas. A long day today. When he heads overwhelm, he was saying earlier that hes looking forward to the r r or a little time in air force one. The nose in that plane, there are two very comfortable beds, also a shower and there used to be a treadmill. I dont think President Trump uses the treadmill too much. I dont know if it is even on there. Hell get some sleep. I think this is the first time he has admitted to fatigue. He seemed to suggest he was pretty tired and could use some r r. Recapping the last two days, the last 72 hours full of headlines. The headline from the last hour from those who might be just joining us was he at the dmz with kim jungun. In the last 24 hours, it sounds like the president is about to start. Hes there live. This is great. Sounds good. But the other actually even sounds better. Thank you very much. At ease, at ease. We are going to have some fun. So we are about 2 30 hours late. I understand instead of losing people, we gained people. Got a hell of a lot of people here, great military people. [ cheers and applause ] it was a little unexpected. Look at all that media back there. Thats a lot of media. We have a lot of media following us. We are doing a great job. You are doing a great job. So important. The reason i met with kim jungun and we had a great meeting because we are all in this together. We want to get this thing solved. It has been going on for a long time. We had a great meeting. It was unexpected. I put out yesterday, maybe ill meet with chairman kim. He saw it. Social media. Pretty powerful thing, social media. We left and i said, you know, this was unexpected. We are going to keep a lot of great military people waiting. Thats what you do. You love your country. That was a good thing to do. I said, theyll understand. [ cheers and applause ] theyll understand. I said theyll understand. So im thrilled to be here this afternoon with the very heroic men and women with the u. S. Air force korea, great place, great country. Ive toured it all. Some day, im going to get back home. It has been a long time. Days. I left japan. I met with every leader. President s, prime ministers, dictators. I met them all. Our country is doing well. Our country has probably never had a better economy than we are doing right now. We are doing great. It is nice to know. You know, you are fighting. You are great people. You are fighting, fighting hard. Just your presence. You have a presence like no other. No other.

I got to see a lot of your fighting comrades. We talked to them. I gave one little speech to a group of guys, another little speech. Then i met with chairman kim and met with president moon. I gave another speech to a group of guys and now im giving a speech to a big group of people and a good looking group. We had a very productive meeting. I outlined the incredible prosperity that awaits north korea when all of this gets settled. Theyve been waiting for this for a long time. Ive had a Good Relationship with chairman kim. You see what is happening. It is very different. They said it was so different before we had the meeting. It was different. It was really hostile. You understand more than anybody. It was really hostile. Since our first meeting in singapore, we got along. When you go back home, youll see it on the television. Youll see it. Today, there are so many forms of looking at things. As soon as you pick one, there is another one and the first one becomes obsolete. I actually stepped in with chairman kim, i stepped into north korea. They say that is a very historic moment. I think it is a historic moment, a very good moment. He asked me, would you like to do that . I said it would be my mondayhon. We went over the line. Many people were very happy. People from korea were literally in tears crying. It is a big thing, a big thing. We are now going to work on something. We have a tremendous team of people that know how to do this.
