Looking at 50 individuals dead and over 200 individuals injured. This is a country of wash and guns. The worst mass shooting in u. S. History. A few minutes ago, President Trump from the white house calling it a, quote, act of pure evil. Announcing he is willing he will travel to las vegas on wednesday to meet with Law Enforcement and First Responders. Here is the very latest. Police say at least 50 people were killed, more than 400 others taken to area hospitals. Some are reportedly in critical condition. We now have photos of the gunman. Identified as 64yearold Stephen Paddock. He lives in mesquite, nevada, 80 miles from las vegas. His brother telling reporters this morning that this comes as a complete shock. The gunman erupted at 10 08 p. M. Las vegas time. The shooter opening fire an automatic weapon who his 32nd Floor Hotel Room at the mandalay bay resort. He targeted the crowd across the street on the final night of a threeday Country Music festival. Witnesses say the shooting continued for five to ten minutes before police burst into his hotel room. Police say the shooter died by a selfinflicted gunshot wound. Heres what it sounded like as it unfolded. We want to warn everyone, you may find this disturbing. [ gunshots ] heres the Police Response as heard on the lay vegas police scanner. Coming from upstairs. Mandalay bay. Upstairs mandalay bae, hay, hal up, i see shots coming from the mandalay bay. Multiple casualties. Be advised, it is automatic fire. Fully automatic fire from the elevated position. Take cover. Multiple gsws. Medical tents. 4a. South off reno. Clip after clip after clip. Bullets flying everywhere. Everybody running. It was really, really bad. Jason aldean was performing, ten minutes in, and we heard what we thought were fireworks. It looked like smoke from mandalay bay. Then he kept performing. We heard it again. They cut the music. Everyone said drop, and everyone dropped. Then everyone just got up and they said, run. Everyone started stampeding and charging. Knocking over grills. Jumping over fences. We were hiding because there was shots going everywhere. There was just dead people everywhere. It was horrible. No other way to describe it. Horrific attack. We have a team of correspondents standing by with all the latest. Starting with Nbcs Joe Fryer joining us live from a room in the mandalay bay resort, a few floors above where the gunman opened fire. Joe, you have a unique Vantage Point. Were looking at images of the hotel where you can see the smashed through window. You can see the curtain blowing through. It wasnt just one window. It was a second. As we learned from pete williams, the gunman, Stephen Paddo paddock, was going from window to window to get a different Vantage Point, as he opened fire on the 22,000 people attending the Country Music festival. Reporter yeah. Thats right, stephanie. So we were actually staying here. It is technically where we are, a four seasons hotel, but it is part of the mandalay bay tower. It takes up a few floors. We were on the 38th floor, and were already here, because we were covering o. J. Simpsons release. It was 10 00 last night. I was asleep and didnt hear anything, but inside this room was my producer. She was also asleep. Awakened by machine gun sound. Thought it sounded like a gun but thought it must have been something to do with the concert that was still going on downstairs. Eventually realized what was going on. It is about six floors below where we are right here. 60 feet below that the gunman opened fire on the crowd below. We want to take a closer look now that the run has risen. You can see from the Vantage Point, this is where the Country Music festival was taking place. 10 00 last night. This area was filled with 22,000 concertgoers. They were listening to jason aldean, who was the headliner here. Imagine about 60 feet below here, this is essentially the Vantage Point that the shooter had when he decided to open fire on all of those people down below. You can imagine if youre in that situation, at first you dont know where the gunfire is coming from. You may not realize it is gunfire. Youre not sure which direction to run. Obviously, there are a lot of places where youre not able to run to, although there were different places s where you cd try to take shelter. In the grassy areas, you do see a lot of items, lawn chairs, blankets in the grassy areas that people obviously left the items behind as they were running for cover and trying to run for safety. Along this area is, of course, las vegas boulevard, the famous strip. Typically it is a bustling area. Right now, the only cars that are on the streets are Police Vehicles and any other Emergency Responder vehicles. Were looking through glass right here. You can see this glass right now, the window does not open. It is a floor to ceiling window. Thats basically the way it is in most of the vegas hotels right now. Obviously, the window did have to be shot out to have any sort of access to shooting toward the concert down below here. Put that in perspective. Down on the ground, blankets and lawn chairs. Thats where people were. 22,000 people came to vegas for a Country Music festival. Think about how their night ended. Joining us by phone is host of the highway on sirius xm. Hes been on lockdown from tropicana for hours now. You were feet from the stage in the artist area when the shots began. What did you think when you first heard it all . Ive heard this from a lot of people already, it sounded like fireworks. Wed been there for three days. This was the last act of our threeday festival. We thought it made sense that it was fireworks. But it was the first time, everybody thought that. The second time, people started to wonder what was going on. When we went outside, it was coming from up above, so somebody actually said, maybe they thought it was from the power lines, that something was going on. About the third time, people started to realize, you know, it was gunfire. We were right by the side of the stage. Everybody started to dive under the artists tour busses that were parked there. We were all underneath the busses for a while. Then security at the venue, at route 91, all of a sudden started trying to get everybody up and moving. We had to actually cross right across the stage. That was our easiest route to get away from mandalay bay. Directly across the stage. Then we kind of merged with all the concertgoers who were trying to escape, as well. It was just chaos. How did you know that being under the bus was the safe place to be . Could you tell where the shots were coming from . No. We knew it was from up high. There was really not a lot there. We were in a tent, so we knew it wasnt safe. The busses were the biggest, heaviest things there. We got underneath. My son had come to visit. He lives in los angeles, goes to school there. I said, ill be in vegas. He came. I threw him under the bus and got on top of him. The bullets were pelting the ground and the dirt was coming up. You could feel it in your face, where can bullets were going by. We thought they were safe there. We didnt know if they were moving toward us or not, so thats why security decided to make everybody run. We did. It was there were people that couldnt keep up. It was people wounded, as well as people who were not so much getting trampled, but it was chaos. There were bottlenecks. It was hard to get out. It was just just trying to get away as fast as you could. Buzz, set the scene a bit more. Because you were in the artist area and you were able to run across the stage and under the bus, there were structures that you could hide under. There were 22,000 people in a completely open area on blankets and lawn chairs. What could they do . How could they run for cover if they were in the middle of the area . There wasnt. There were structures for us. We were around the scaffolding, the stage and the busses. The middle my room at mandalay bay was on the 23rd room. When my son got there to visit, we were looking out the window the day before. I said, look, theres the venue right there. We could look down on it from the same Vantage Point that the gunman had. You saw the stage. You saw some bleachers in the background. You saw some catering. You saw some tents. Then you saw a huge area that was basically a parking lot where the 22,000 people were watching the show. I had been on stage just before that with jake owen. I brought him on stage and looked out from the stage. All i saw was a sea of kocountr music fans. I couldnt see the end of it. It was this lull of people and i didnt know where it ended. I couldnt see it. You had a large team with you from xm. Is everyone accounted for . Yeah. That was we all went in different directions. I had my son with me. I had another one of my coworkers with me. We got split up. We started a text chain immediately. Then we had to reach everybody through email. Our team is all safe. We have a lot of people from our National Community there. I tried to get in touch with as many people as i could from nashville. Luckily, we havent heard of any of our friends who got hurt yet. But a lot of people did. Everybody we didnt know where everybody was. The closest place for me to go was tropicana. Once we got there, we didnt know what was going on. All of a sudden, people are getting snippets of news from their phones. Somebody yells, theres another gunman. Hes at mgm. Then tropicana. So it turned into chaos again. Finally, security there was graet great. They got us into the Convention Hall and padded down everybody. We were in lockdown there. I finally just got out. Of course, not going back to mandalay bay for a while yet. Thats where all our stuff is. All right. You said two things. It was chaos but security did an extraordinary job. Talk us through your experience. I mean, what the Las Vegas Police department had to do last night, all the people that they did protect, and putting themselves in the line of fire when somebody from up above, with an open shot at 22,000 people, and as we learned, a variety of assault weapons were firing down on the thousands of people. Talk us through, from your perspective, what the police did last night. Security on hand was phenomenal. They were they were there getting us out. Police were on hand for the entire festival because the traffic, just the foot traffic alone, they were there for that. So there were squad cars everywhere. So when this broke out, one of the first things i saw, the road that runs parallel, the other side of las vegas boulevard, the other side of the venue, we crossed there and there was a squad car. They were crouched behind it with their rifles aimed up toward mandalay bay. Unfortunately, i did see an officer who appeared to be down there. A couple of his comrades covered him up. The Police Officers, sirens immediately. It seemed like the whole thing went on maybe ten minutes. It wasnt long before we heard the sirens. Then when we finally got to what we thought was safety, the Las Vegas Police department did everything they could to tray to let us know what was going on. A Police Officer who spoke to us while we were in the Convention Center said, you know, please dont let this be hold this against our city. Were here for you. They just try to keep us informed. Try to let us know what was going on. They did a great job. All right, buzz. Were so relieved to hear that you and your team and your son are safe. Thanks so much for joining us and sharing your experience last night. As we are trying to figure out exactly what happened and why. Live on the phone now, karen sherman, who was at the concert and witnessed the shooting. Karen, were glad to hear youre safe. Everyone who was with you, are they accounted for and safe . Yes, they are. Thank you. Where exactly were you when it all happened . We were towards the back of the crowd. My friend and i, she wanted to move forward to the stage. I said, lets stay here because there were too many people up front. No sooner did she say that, we heard a first shot, which we thought was a firework. We were thinking, oh, jason aldean brought fireworks. This is an awesome concert. The next shot went off. After that, it was this da, da, da, and we thought it was not gunshots i mean, this is not fireworks. This is gunshots. We took off running. We didnt see anybody physically get shot, but we just took off running. We were parked on the side of the venue. It was like vip employee parking. We ran to my car. Everybody was pushing each other, trying to get through to a safe area. When you say you took off running, how did you know where to go . Did you know where the shots were coming from . No. I had no idea. It sounded like it was coming from the far right of the stage when youre facing it, but it was just hard to tell. They were getting louder and louder. We just took off running. Just followed a lot of other people. But people were running every which way. How long did it take before you got to safety . How long was it im sorry . How long did it take for you to get to safety . From the time you heard the gunshots fired till the time it took you to get to your car or whatever you were safe, how long was that . Oh, gosh, it must have been i dont even know. Probably, like, ten minutes to get to the car. We got in the car. We started driving off. Three people jumped in the backseat of my car, trying to get to safety. I didnt know who they were. I said, just get in the car. We have to get out of here. We drove to the closest exit that we found and then there was a girl standing in the middle of the street and waving her arm. People were passing her up. My friend said, stop the car. The girl put her arm up and blood was pouring out of her arm. She was shot. So we grabbed her, put her in my car and we went to a place called sundance helicopters. It was the only place we could go to get everyone to safety. What happened to the girl . We got her inside. They put us into a hangar, helicopter hangar, and we got her inside. We were screaming for, like, anybody that was a nurse or doctor. We need help. An emt came and a nurse came. My friend took off her shirt and wrapped the girls arm up. Then the emt and nurse took over. Was your friend a nurse . Shes not, no. She just knew what to do though. Karen, thank you so much for sharing your story. Thank you for your act of heroism last night. You most likely saved that womans life. Thank you. Lets bring back nbc news justice correspondent pete williams, live in washington. Pete, i know youve learned more about the shooter. A little while ago, we were sharing more of the statement from his brother, bruce. We should put into perspective that his brother, bruce, has not spoken to Stephen Paddock in ten years. I do want to share the statement he made, where he said, quote, hes not mentally deranged. Hes quite smart. Hes not been involved with the police like i have my whole life for minor stuff. He never got into fights. He never did anything violent. Hes kind of laid back. Never in a hurry. He was always lawabiding. Again, a lot can happen in ten years. As the psychological profile is built out from Law Enforcement, theyre going to learn a lot more about this guy. What have you learned . Clearly. And his brother, eric, has spoke en to our affiliate in orlando and says that he was in very regular and close touch with Stephen Paddock. He says that paddock texted to find out if everything was all right after the recent hurricanes. Checking on the condition of his mother who lived in florida. That erics the brothers son says that the son recently contacted Stephen Paddock to see if he was coming to his wedding. The brother says that he Stephen Paddock lived for a time in melbourne, florida, and then decided to go back to nevada. Were told that in nevada, he was a frequent person at the casinos and hotels in las vegas, so was certainly familiar with them. We know that from 1985 to 88 Stephen Paddock worked for lockheed, we believe as an accountant. Lock seed heed says theyre cooperating with authorities, providing the information they can. Eric, the brother down in orlando, says the two of them own some apartments together for a while. We believe that was in texas, that they owned apartments together. Now Stephen Paddock had been living at this Retirement Community called the sun city Retirement Community in mesquite. Is isis, terror group, claimed that paddock converted to islam and he was, as they say, a soldier of the caliphate. The federal Law Enforcement and intelligence people we talked to say they have absolutely no reason to believe that that is true. They simply dont know. The brother down in orlando says that he didnt believe that there was any religious motivation or any religious conversion or anything else, significant event in his brothers life that would lead him to it. The brother in orlando says he is completely at a loss. Totally stunned by this. Never saw it coming and didnt think his brother was capable of it. But you had said earlier he is a regular in vegas. Likes to gamble, likes the shows. Yes. And had spent, according to Law Enforcement, stephanie, had recently, in the last couple of weeks, moved a fair amount of money through these casinos. Tens of thousands of dollars. We cant tell from the data here whether this was tens of thousands of dollars in losses or tens of thousands of dollars of wins or he just put the money in play and took it back. The point is, he was apparently a frequent gambler and a high roller at that. How about any sort of history with the law . Well, no criminal connection with the police, according to the police in las vegas, and his brother says he never had any runins with the authorities in florida either. There was a civil fine of some kind at some point, but no co
