We have new details now from that dramatic interview we had yesterday with a woman who was stranded on a roof in Houston as those flds were quickly rising all around her and her family. Iashia Nelson waited and waited and waited and finally all of that waiting paid off and the rescue came and just moments ago look at that. She reunited with her rescuer and iashia is going to join us live again with her rescuer in just a moment but first we want to take a look at what happened. As the hours pass after this emotional plea -- Please help us. I'm scared. Reporter: Iashia Nelson's situation grew increasingly desperate. We don't have no food. I haven't ate in two days. No water. I'm praying that they get us because if they don't get us sooner's not going to get us at all. Reporter: The 36-year-old mother of three remaining trapped in a Houston apartment building with about 30 other people watching the floodwaters rise and live streaming the grim details across social media. We need help. We need help right now. They got a whole family out there in the water. And people is drowning. I seen three dead bodies. Please help us. Reporter: These videos shared hundreds of times across Facebook until finally -- Put on a life jacket. Reporter: Volunteer rescuers arrived in a boat first bringing children to the safety of the shelter then quickly returning to help iashia and the others. The family reuniting here at this packed shelter a few hours later. Their lives now forever changed since their ordeal began just three days ago. And joining us now is iashia Nelson along with her sister Melissa Nelson and their rescuer James Murphy Jr. Thank you so much for being with us and, iashia, when we last spoke to you 24 hours ago, you were desperate. Tell me how you and your family are doing now. We are grateful. We are grateful that we was able to get out of that water. I wouldn't wish that on nobody. It was so scary because you just didn't know when help was coming. And finally help came in the form of James right there so, James, tell me what happened. How you came upon iashia and what the rescue was like. Well, basically the water in order to get to them, we tried a few boats. Boats, very dangerous. The currents were strong as you can see in the videos. It was a big risk and we just wanted to basically get them to safe grounds. First we had to screen the entire property to know what we were working with. So with that being said, though, currents is just strong out there. I want to just wish anyone that's in this water to be safe and be aware of the currents. The currents are very strong out here. Yeah, you can see that in the video just how fast that water was moving and how quickly it was rising. Iashia, can you describe the moment when you saw that help was here and that they were going to be taking your children and your family to safety. What was that moment like after so many hours of not knowing? I was so emotional, I couldn't hold back my tears. I was crying. I was so happy to see my kids getting on that boat and all those children we had with us getting on that boat. I don't know what I would do if James and the cajun Navy and another set of volunteers, Robert Rojo, I don't know who the others were but I'm so grateful for those who came and their service, especially James, they were the first ones to come through. He came through with a boat and he passed us up first and we were hollering and he said I be back for y'all. I promise. He kept his word and I'm forever grateful to him. I don't know what I would have did. I know you were on that roof. Melissa, you had no food, no water. What are you going to take away from this experience? What I'm going to take away is like -- it's just so much because when James first came I was the first one to spot him so I started rolling my camera and asking for help. They couldn't get through because of the current. He and his friend came. His boat was getting hit and pushed because the current is in front of my door and even though the boats was there, he still was coming. He was just let me get the kids first. Putting them kids and all the people and trying to get as many people as we can on the boat. We was the last -- I know I was the last one to leave before the helicopters came by. The cajun -- Cajun Navy. The cajun Navy and James -- His friend, they was the best. We are so grateful. And Mr. Robert Rojo. I don't know who those people were. We're glad you are okay. James, you saved more than 100 people yesterday and I know you're going back out in the water today. So thank you for all that you've done and we're just so happy you are all okay. I want to thank you and I want to give special thanks to Mr. Rudy, that was his boat and he allowed me to assist him with great teamwork and just thank you, Mr. Rudy. That's incredible. Well, thank you all for joining us. Hope you have a much better day today and it's important to note when we got that, that call from her and we were talking to her you asked for her address. Our producers were calling the coast guard, calling officials trying to get help and just kept getting a busy signal and that's how backed they are. If not for James there's no telling how long it would have taken. Whole team of heroes. Other news to get to
