Light turned off and jason aldean disappeared, we knew thing was wrong. After that, we just started running. Felt like it would never end. And there was just dead people everywhere. It was horrible. This is a classic wmd. This is a weapon and a man of mass destruction. Reporter First Responders risking their own lives to save others. There were Police Officers who laid over the women who were there to make sure they would nlt get thought sat. But for the fact that their selfless actions, weed have dozens more casualties. It was one of the most beautiful craziest things ive seen in the sight of a tragedy. Today authorities in las vegas continue their investigation into what led a gunman to commit the worst mass shooting of its kind. Opened fire on a Country Music concert attended by 22,000 people here in las vegas. He fired from the 32nd floor of the mandalay bay rezorsort and casino. Tonight police gave an updaten their investigation. Metro and its partners have executed a search warrant in mesquite, nevada. Theyre combing through the evidence and information that would help shed light on this horrible event. Weve recovered 23 firearms at mandalay bay and in his home in mesquite. They said they found a computer in the suspects hotel room that they are examining. Earlier today police said they found explosives and thousands of rounds of ammunition at the shooters home. They were searching a second home in reebo, nvl nv tonight. Were joined by nbc news reporter, ron allen and what is the latest tonight . Lot of unanswered questions. They dont seem to know a lot about this guy. They say they had no contact with him, not even a parking ticket before this incident. Theyre trying to piece together his life, where he was in the days leading up to this. Was he upset about a gambling debt, which is something we hear floating around. What kind of emotional problems did he have and why . Authorities say still interested in the girlfriend because they had 19 fairly significant weapons in their home. And if youre living with them like she apparently was, she would have something to say about how long it took to acquire this and probably something to report about his moods and what things he might have been thinking about. In some cases and theres no social media, they say. Theres no manifesto, no letters that he left behind. This guy seems to have come from nowhere, although thats where we are now. We heard from his brother today who, at his home yelled some responses to reporters. And everything he seemed to be saying was there was no reason to suspect anything about this. He did tell us that the guy was in effect a gambler for a living. That is the way he lived. But we didnt pick up anything from his brother and his brother, apparently wanted to take him at his word have no suspicion. Thats what he says. He also says hes a multimillionaire. But in these situations we try to find a logical explanation as to why someone would do the unthinkable. Theres no way to explain such a horrible thing. And there will be some explanation but why someone snaps like that and anileates so many innocent people is senseless. Thank you for joining us. Appreciate it. Reporter were joined now by joseph. He was here last night. Tell us. We were enjoying the music. Reporter it was right behind us. Right behind us. Jason aldean was on stage performing and we were having a great time. Then all the sudden we heard what sounded like fireworks in the distance but they kept coming and coming and coming. How many friends were you with . About 10 people. Reporter and so youre reacting with each other about what is this . We were all kind of looking. But we kept looking in the distance expecting to see a firework or something. None of us realized it was gun shots until jason aldean went off stage and people started shouting and screaming. And we realize we needed to get out of there. We ran. Our whole group just ran. And were you running with someone in particular . I was with my friend. Her names kristen and she was shot in the shoulder. And when did she know she was shot . She was complaining when we were walking out of the venue about she kept saying she got hit by a water balloon. And she was hyperventilating. I thought she was just not over reacting but dealing with the panic at the moment. And then when she started coughing blood, i knew she been shot but i felt her and i couldnt feel a wound and i go we need get out of here and you couldnt see a wound he was bleeding from . We actually climbed this gate right here behind the National Stage and ran up this street. When we got to desert rose we checked her again. There was actually concert goer, paramedic and she stuck with us. Eventually turned 92. Were you able to see her that hospital . I was with her all day. Are you stuck in las vegas . I live here now. And what about your other friends there. Somebody told me tlz rur another group associated with tough have you been sleeping . Ive had about two hours of sleep. Im dealing with emotions. Ive spoken to somebody. Ive spoken to a professional. And its good to come back here and kind of face what happened. And it actually does help a lot to talk about it and to be here. Some people would think youd want to get away from it and not think about it. I think being here and seeing how it is now, it just gives you another perspective because you just reclaimed what we saw last time and that was remember sad. And im sure youve seen a lot of the video that was shot last night. I havent been washing the news. That is the wrun thing i havent done. Im not ready for that yet. You think youd be reliving it watching the video. I saw a couple clips and did feel like i was the more it effects you less and less. When you were trying to get out of here, what was the point when you knew you were safe . When we got to the hotel i knew we were safe because we were out of range. And did you hear these reports going around last night that she was shooting in more than one place. But apparently all there was a lot of confusion. So once you got out of this area, you knew you were safe. Really appreciate it. Thank you. Coming up. It john on whats happened in his city. Remember that accident i got in with the pole, and i had to make a claim and all that . Is that whole thing still dragging on . No, i took some pics with the app and. Filed a claim, but. You know how they send you money to cover repairs and. They took forever to pay you, right . No, i got paid right away, but. At the very end of it all, my agent. Wouldnt even call you back, right . No, she called to see if i was happy. But if i wasnt happy with my claim experience for any reason, theyd give me my money back, no questions asked. Can you believe that . No. The claim satisfaction guarantee, only from allstate. Switching to allstate is worth it. Only from allstate. When food is good and clean and real, its ok to crave. And with panera catering, theres more to go around. Panera. Food as it should be. Its easydrinking. Its refreshing. If youve got the time its what american lager was born to be. Weve got the beer. Welcome to the high life. Miller beer. 9 out of 10 couples prefer a different mattress firmness, so we created the only bed that adjusts on both sides to your ideal comfort, your sleep number setting. You can even see how well youre sleeping and make adjustments. Does your bed do that . The most amazing part is they start at 699. Thats 200 off our queen c2 mattress s wll here we are again in the aftermath of another terrible, inexplicable, shocking and painful tragedy. This time in las vegas, which happens to be my home town and cletos home town and cleto srs home town and as you know 59 people are dead, hundreds others are wounded in what they say is the deadliest mass shooting in modern american history, coming a year after the previous deadliest mass shooting ever in orlando and of course we pray for the victims and their families and friends and we wonder why, even though theres probably no way to ever know why a human being would do Something Like this to other human beings who are at a concert having fun and listening to music. Reporter and that is how jimmy kimmel began his show tonight. Were joined by the editor of the nevada independent and a las vegas resident. John, this is your town. I cant imagine youve been sleeping since this broke just over 24 hours ago. Tell us what the citys been through. Tell us also what you have been through. What is the life of the reporter been today in las vegas. Now that ive become an editor and you have to supervise this entire team and have them sent out all over this valley to pursue stories. Remember when we were young and we could do that. Theyre not just pursuing the story, trying to piece this together, expressing the same kinds of frustrations that you and yob would express. They feel the frustration by the end of the day. As you engz ammed i live here. My son wanted to go to that concert very badly with his girlfriend. Tried to get tickets. They were sold out. His girlfriend called radio stations desperately to get tickets. Thank gad they failed. I cant imagine what people are going through thinking bot their loved ones and friends being there. Las vegas has a certain reputation. Its easy to mock las vegas or be cynical. This town really has responded incredibly a gofund me account with 2. 5 million. Hundreds of people donating blood and off duty policeman from california who happen to be at that concert. Its difficult to describe the enormity of whats happened here. But that at least is the silver lining. Lets listen more to jimmy kimmel who grew up in las vegas. Ive been reading comments from people who say this is terrible but theres nothing we can do about it. But we dont. We build walls, we take every precaution to make sure it doesnt happen again but when an american buys a gun and killed other americans, theres nothing we can do about that and Second Amendment i guess our forefathers wanted us to have ak47s is the argument i assume. And john, were going to be seeing more of that discussion with jimmy kimmel is presenting tonight. Its so depressing. I was talking to a friend of mine who own as big company and he just expressed his frustration. Were having the same discussion. The polaratiization. I thautd it was over after sandy hook. But people are in their camps right away. You mentioned jimmy kimmel grew up here. I only saw him once in person at wedding 25 years ago and he was this joyful, hilarious guy but since his experience with politics, the health care battle, he looks defeated and sad the way a lot of people do because its a replay. Just the same old thing over and over. I noted the assisted sheriff tonight in the press conference stressed how safe everyone now is in las vegas and how this was one person, one shooter. People did not have to worry about a bunch of false reports, indicating there was more than that. I have friends here who this morning kept their Children Home from school. Thats how afraid this city was when it woke up this morning anyway. And its different world. There was a report of a truck with bombs on it it at the luxor hotel. But even the truth is horrific. The guy is up on the 32nd floor shooting down into a bunch of sitting ducks with nowhere to hide and people, the distrust of instugzs. People might not believe the police its totally safe. I dont know if they plebelieve themselves. Since centration of people at big events, theres always been a fear that Something Like this could han and it has. We had a guest in my earlier hour tonight speculate this could stop. Basically stop outdoor concerts in las vegas because there are so many big buildings with lines of sight with this near the outdoor location sights in las vegas. Theres going to be all kinds of considerations, what to do. This town cannot exist without tourism. Are they just going to be afraid to go to outdoor concerts and small inclosed places with huge buildings . Are they going to be afraid to go to these hotels . Generally 99. 9 of the time its as safe as anywhere you can go. But now this is all over the world. So people will never feel the same, i dont think, about coming here. Where do you think this citys going to be at the end of this week, end of next weeking . You have to get past the preening by some of the politicians and desire to take advantage whether its politicians or special interests. Why did this guy do it . We know surden things about him but we dont know why he did this, what more might or might not come out. Sgl i have been very critical of don don. I was very surprised president ial he looked today but who knows what hes going to do in puerto rico. So who knows what kind of demeanor hell have. The governor is a huge critic of don don. They do not have a good relationship. Can everyone show unity during a president ial visit. With trump you never know. Thank you very fluch joining us and im really sorry for everything youve had had to endure in the last 24 hours. Coming up Rachel Maddow, chris hayes will join us.

Woman 2 and i know thats hard to hear, but the doctors caught it early. Hi, blake my dad has cancer. Woman and i know how hard that is to hear. But youre in the right place. Man and dr. Pascal and her team, they know what to do. They know what to do. The doctors know what to do. So heres the plan. First off, were going to give you all. voice fading away last night a gunman opened fire on a large crowd at a Country Music concert in las vegas, nevada. He brutally murdered more than 50 people and wounded hundreds more. It was an act of pure evil. That was the president addressing the nation this morning. And calling for unity and paeea after the las vegas shooting. Both the white house and congress observed moments of silence in honor of victims of the shooting. Pt will meet with Law Enforcement, First Responders and the families of victims. Heres the White House Press secretary on whether the shooting will have any impact on the president s position on gun control. This is an unspeakable tragedy. Today is a day for consoling the survivors and mourning those we lost. Our thoughts and prayers are with those individuals. Theres a time and place for a political debate but now is a time to unite as a country. Theres an open Law Enforcement investigation. A motive is yet to be determined and it would be premature to discuss policy when we dont fully know all the facts or what took place last night. Were joined now by Rachel Maddow and chris hayes. Watching Sarah Huckabee sanders say that, im taken back to orlando and watching then candidate trump the day after that shooting call on a full ban of a billion people to come in the country. There was no sense then that it was too early. There was a day to console victims, that we need to get the facts. And it should be clear are totally reasonable things to say. But that is a standard its almost kind of maddening because its unevenly applied by this white house whos jumped out, who has run with the first reports of all sorts of things and its a very different Sarah Huckabee sanders. Theyre happy to acknowledge, except when except when it doesnt fit in the box they have. Its been a really, to me, unnerving tendency of the president to tweet about things happening that appear to be act by say isis or jihadists of some sort. An hour into it. While people are figuring out what happened. You see all the suden the restraint that doesnt check that box. Because its about guns. And the thing that seems different about this and i mean even compared to pulse, even compared to sandy hook, even to virginia tech. Is this killer appears to have put together an arsenal that seems to have been maxing out what you can do with legal weapons. And we still dont know about the automatic weapons fire. We have subsitions whether he modified it and what that means. We just got it at the press conference. In the hotel room 23 guns at his property in mesquite. Were told through other reporting services, all rifles there. If we was using weird after market modifications on those guns, they make your gun dwli glitchy. You can solve that if you have 20 of them. As soon as one misfires, you grab another. It makes the financial aspect interesting, technological question interesting. Even before we know about his motivation or connections to anybody else and we, as a country decided we couldnt talk about that, at least at the federal level in terms of whether or not we can have a practical discuss. One thing they dont want to talk about is silencers towards deregulating silencers which would have made this even wursz. Tleing us they didnt think it was gun shots at first. Any kind of silencing capacity on this, what would it have taken . Thad stroor see the bodies falling before any of it to deregulate silencers. A lot of disinformation, not just miss information, they sartd saying that silencers tool see what kind of exotic weapons you can pay to shoot round here. And everybody told me oh, yeah, you can put silencers in that kind of weapon. Why you would need silencers when you can just use ear plugs. We have now come to apply to events like this and could be a terrorist attack from isis ear red flag. Some rage that descented to meet her again. At some level theres a. Standing here looking at what this person did is so gastly and horrible and took such a combination of planning and benevolence without any an mating reason that we know of that at this point it feels like it from thexs my capacity to conkeptual i have been a lifelong compone rnt of the second mendment. I cannot express how wrong whereby was. He has completely rehearsed himself on the Second Amendment and whats really surprising about that is we dont normally have Something Like that to refort. Even the person who changes their find the mind about it.
