[19:00:00] WOLF BLITZER, CNN ANCHOR: Erin is in Las Vegas right now.

UNIDENTIFIED MALE: This is CNN Breaking News.

ERIN BURNETT, CNN ANCHOR: Good evening, I'm Erin Burnett live in Las Vegas tonight. And welcome to our viewers across the United States and around the world.

OutFront tonight, the horrific breaking news. At least 59 people are dead tonight, 527 are injured. This is the deadliest mass shooting in modern American history. It is an unspeakable tragic, and it began late last night here where we are along the Las Vegas Strip.

BURNETT: That was the sound of the storm of bullets that hit a massive crowd of concert goers. And we are just learning new details about the gunman and how this could possibly have happened. He's a 64-year-old former accountant, his is Stephen Paddock. Firing a barrage of bullets from a hotel room. He was 32 stories above that crowd.

Moments ago, police revealed that the shooter had 16 guns with him inside his hotel room which was at the Mandalay Bay which is the casino directly behind where we're standing. Police also found ammonium nitrate which a highly explosive inside the shooter's car.

(INAUDIBLE) which is another highly volatile explosive was found in the shooter's home. The carnage from this mass shooting is truly horrific. There aren't words to imagine what happened here.

I want to warn you that the video we're about to show you is very disturbing. This is what you see here, this was the scene. Witnesses saw bodies everywhere. Everywhere is what they're telling us.

The injuries were horrible. So many people shot, others were trampled, others hit by fragments and all of the pavements that came up. Chaos as 22,000 people ran from the gunfire that to so many seemed never to stop. The big question tonight is still, why? Why would this person from Mesquite, Nevada, 80 miles from Las Vegas, living in a retirement community, described by his brother as a multimillionaire, why did he do this?

Paddock's brother, Eric spoke out earlier today, and he says that he's equally mystified about his brother and how this could have happened.

(BEGIN VIDEO CLIP)

ERIC PADDOCK, BROTHER OF LAS VEGAS SHOOTER: We're lost. I don't understand. It makes -- there's no anything. Not an avid gun guy at all.

The fact he had those kinds of weapons is just -- where the hell did he get automatic weapons? He doesn't have a military background or anything like that. I mean, when you (INAUDIBLE). He's a guy who lived in a house in Mesquite and drove down and gambled in Las Vegas.

(END VIDEO CLIP)

BURNETT: And we begin our breaking coverage with martin Savidge. He is here with me in Las Vegas. Martin, they just gave an update and now you have more information on part of this why. And his brother talking about this, where did this arsenal come from.

MARTIN SAVIDGE, CNN CORRESPONDENT: Yes. You know, every time we have one of these updates, you just get more stunning revelations. And so, they're working on the crime scenes. As we know, they're working on the hotel room, they're working on the concert venue and then of course, two residences belonging to the gunman.

It's the Mesquite residence, a primary residence where authority say, in addition to what was found in the hotel room, they had found 18 more weapons. They don't go into details but they also say thousands and thousands of rounds of ammunition.

So it is another arsenal that was found there. And on top of that, they said they found explosives and they found electronic devices. Again, they don't go into detail on that. So, that's what they discovered so far as the weaponry and it's just amazing.

BURNETT: It is impossible to comprehend. I know that we also know that they are saying that he killed himself perhaps just before they entered the room. But you're learning more about that incident?

SAVIDGE: Right. It's been back and forth on this one. You know, it was initially reported that perhaps he had taken his own life at the very moment the SWAT Team was making entry on his hotel room in the 32nd floor.

Now they've clarified that point, they say that as the SWAT officers broke in the door that the gunman charged them, made it through the door, struggled with the officers and was able to get at least one shot wounding one SWAT officer in the leg and then the gunman was killed. BURNETT: There was interaction. All right, Martin Savidge, thank you very much. And, you know, when you think about what happened here, it happened over 10 to 15 minutes which can seem like an eternity or sound like not much time at all for such horrific carnage. At the end, 59 people as of this moment have died, 527 more are wounded tonight.

(BEGIN VIDEO CLIP)

BURNETT: Just after 10:00 p.m. Monday night, gunfire rained down on a crowd of 22,000 country music fans, out in the open along the Las Vegas Strip.

[19:05:07] 10:08, the first 911 calls to police.

UNIDENTIFIED MALE: I'm inside the Mandalay Bay on the 31st floor. I can hear the automatic fire coming from one floor ahead, one floor above us.

BURNETT: As you can see here, the crowd is some 400 yards away from the sniper's nest in the Mandalay Bay Hotel, completely exposed in an open field. Authorities believe the shooter used a hammer to smash out the windows on his room on the 32nd floor.

UNIDENTIFIED FEMALE: The gunshots lasted for 10 or 15 minutes. It didn't stop.

UNIDENTIFIED FEMALE: Everyone said, hit the floor, so everyone was just like literally laying on top of each other trying to get out of the way. and the shots just kept coming.

BURNETT: At first, confusion in the crowd. Then panic. Chaos, thousands of people literally running for their

lives.

UNIDENTIFIED MALE: Get down. Get down.

UNIDENTIFIED FEMALE: Why is there blood?

UNIDENTIFIED MALE: No matter which direction you went in, no matter where you took cover, there is at least two to three bodies that you're a part of it and you didn't know where you were safe.

BURNETT: Within minutes, dozens lay dead, hundreds more injured.

UNIDENTIFIED MALE: People are climbing the fences, pushing their way through the barricades. We're coming down, people were screaming, crying, everybody was just trying to get out.

UNIDENTIFIED FEMALE: We had a man come running up to us, blood down his shirt saying his friends were dead. His friends were dead.

BURNETT: Las Vegas first responders were quick on the scenes, but faced with an overwhelming task. The gunman holed up somewhere inside a 43-story hotel with more than 3,000 rooms. But thanks in part to 911 calls from inside the hotel, officers were able to locate him quickly.

UNIDENTIFIED MALE: We have sight on the suspect's door. I need for everybody in that hallway to be aware of it and get back. We need to pop this and see if we can get any type of response from this guy. See if he's in here or if he's actually moved somewhere else.

UNIDENTIFIED MALE: Breach. Breach. Breach.

BURNETT: 11:28, almost an hour and a half after this nightmare began, police blow the shooter's door. Inside, 64-year-old Stephen Paddock lay dead. Police believe Paddock shot (INAUDIBLE). (INAUDIBLE) in the room, at least 10 rifles.

PADDOCK: He was my brother. It's like an asteroid fell out of the sky.

BURNETT: Eric Paddock seemingly in disbelief that his brother could be behind the deadliest mass shooting in modern American history.

PADDOCK: There's not even anything I can say. I mean, how do you -- I mean, my brother did this. This is like it was done, you know, like he shot us.

(END VIDEO CLIP)

BURNETT: OutFront tonight, someone who was on stage during the shooting, country radio host Storme Warren. Storme, your life has completely changed.

STORME WARREN, COUNTRY RADIO HOST: Yes. Everyone who was there, everybody who's watching the coverage of this, I think all of our lives have changed.

BURNETT: And you were there, obviously. You were really on stage essentially as this started?

WARREN: Yes. Jason Aldean was about 30 minutes or 20 minutes into his final headlining set for the entire festival weekend, and rat a tat tat, we thought it was pyrotechnics, maybe an audio glitch in the system. We didn't think (INAUDIBLE) we knew definitely we were under fire. And I got Jason and the band off stage, got everybody off the stage and started tending to people as quickly as possible.

BURNETT: (INAUDIBLE) but so many people are filming the concert with their phones, there is audio of some of what happened. And I just wanted to play a piece for you because when people hear it, they -- it might feel, you know, probably as I know you felt it first, it was sort of part of the ac. Let's give a chance for those who were not there just to hear that first moment.

(Gunfire)

BURNETT: I can't imagine what it's like for you to -- you probably hear that in your mind all day?

WARREN: Yes, yes. I mean, we had to turn the volume down last night like 3:00 in the morning. We couldn't sleep. Every clip played those bullets back and forth. And the gunfire -- it's a sound no one should have to hear in our country, anywhere.

BURNETT: And you -- at first you didn't think it was part of the act, but then immediately you started rushing in to try to help people as people start to run because after there was that first barrage of bullets, there was then a pause, right? A brief pause as you ran out to help.

WARREN: Well, there's a -- I guess he was reloading and there's volley after volley of machine gunfire. We didn't know when it's going to end. It seems to go on at least 20 minutes or so. And at that point we were just hiding and just trying to make sure that we were not going to be exposed.

[19:10:02] We didn't know exactly where it was coming from. We kind of assumed it was coming from the rooftop of the Mandalay. But we just tried to put something between us and where those shots were coming from.

And only after about maybe 20, 25 minutes of silence did we feel like we could go out and then try to tend to people. That's where the true horror actually revealed itself. Because we saw a few wounded, like somebody did get hit. And we walked into the ball where all the fans were, and it was empty beer cups, trash, and bodies.

BURNETT: And that's when you realized people were dead.

WARREN: I didn't realize to the extent of what the carnage was. It's too tough actually for anybody. Then to have the injuries and people screaming for help, and not enough help right at that moment. I think the first responders got there as fast as they could and they did an amazing job, but (INAUDIBLE) the humanity that revealed itself last night.

Veterans, (INAUDIBLE) I have medical training, I can help, is anybody hurt, and helping everybody, whether it was comfort, water, towels, whatever, everybody chipped in and tried to do whatever we could.

BURNETT: So many people there lying, wanting help. From what you could see, were the people who could still benefit from help, getting it?

WARREN: Not as fast as I think they or any of us would have liked. That was the hard part. Some people dying literally. Some things we just couldn't do.

BURNETT: When you think about what happened, do you have any comprehension -- you were saying you had a feel for where the bullets were coming from. And now you're starting to hear these things about this person. How anybody, anybody could do something like this person did?

WARREN: I can't put it in words, I can't think about it. I can't think of what person breaks an open window, points a rifle out the window at a sea of people having the time of their lives, and what he plans to get from that. What is the goal? He ends up dead anyway. What did help he want to achieve?

And I don't think any of us were going to have those answers.

BURNETT: What do you do now Storme?

WARREN: (INAUDIBLE) as much as we can. We'll still have these festivals. Entertainers will still entertain. Country fans will still come out and enjoy the music, and we will not let this stop us, but we're going to pause for a minute.

BURNETT: Of course, you have to. Storme, thank you.

WARREN: Thank you.

BURNETT: OutFront next, more details about the shooter. This big question of how a human being could do something like this. His father was a bank robber, he was on the FBI's most wanted list. But how did he get into such a major hotel with 16 firearms.

Automatics or semiautomatics there is Las Vegas is my guest. And there heroes, there are so many heroes (INAUDIBLE), people who rushed in to try to help people and save a life of someone who was clinging to it on the ground. One man risked his own life to get others to safety. We're going to talk to him tonight. And we'll be right back.

(COMMERCIAL BREAK)

[19:16:57] BURNETT: Welcome back to our viewers in the United States and around the world. The breaking news, a SWAT Team about to enter the home, one of the homes of the gunman behind what is now the deadliest shooting in modern American history. We are learning disturbing new details about the 64-year-old shooter.

The county sheriff revealing that in addition to 16 guns in his hotel room, they're saying there were 18 additional firearms at his home. The home that they believe he came from here to the Mandalay Bay, as well as several thousands rounds of ammunition and explosives.

Authorities also found ammonium nitrate in his car which is -- of course what was used to carry out the Oklahoma City bombing in 1995, essentially fertilizer. Kyung Lah is in Mesquite, Nevada near the shooter's home. And Kyung, obviously we are learning moment by moment here so much more.

KYUNG LAH, CNN NATIONAL CORRESPONDENT: And what's becoming very clear, Erin in those frightening numbers that you're sharing is that it appears he was stock piling in this retirement community, that he potentially could have done a large amount of damage with all of that ammunition and that weaponry and the explosives. But what is not clear is the motive, the why.

(BEGIN VIDEOTAPE)

LAH (voice-over): When the SWAT Team broke down the door of a room on the 32nd floor of the Mandalay Bay casino, gunman Stephen Paddock was already dead of a self-inflicted gunshot wound. Leaving investigators to piece together why a 64-year-old retired accountant would gun down a crowd attending the Route 91 Harvest Music Festival.

SHERIFF JOE LOMBARDO, LAS VEGAS METROPOLITAN POLICE: We've checked all the federal databases and local databases and state databases and we had no knowledge of this individual.

LAH (voice-over): Paddock checked into the Mandalay Bay on September 28th but it wasn't until Sunday night that he broke through the windows of his hotel room to begin his murderous rampage. Police would find 10 or more guns in the hotel room.

LOMBARDO: This is an individual that was described as a lone wolf. I don't know how it could have been prevented if we didn't have any prior knowledge to this individual.

LAH (voice-over): The gunman's brother, Eric Paddock says he also had no warning. He lives in Orlando, Florida and says the last time they spoke was after Hurricane Irma.

PADDOCK: He was my brother. It's like an asteroid that fell out of the sky. Last time I talked to him was he texted me to ask how my mom was after we don't have power for five days in the neighborhood.

LAH (voice-over): He says his brother was rich, playing $100 hands of video poker. Paddock was divorced with no kids.

PADDOCK: Steve had nothing to do with any political organization, religious organization, no white supremacist, nothing as far as I know. Yes, he had a couple guns. I mean, it's legal to own a couple guns in the United States. He did not own machine guns that I knew of in any way, shape, or form.

LAH (voice-over): The only unusual part of Paddock's family says his brother, his father a convicted bank robber Benjamin Hoskins Paddock was on the FBI most wanted list from 1969 to 1977.

PADDOCK: He's dead. Yes, he died a handful of years ago. I was born on the run and that's the last time he was ever associated with our family.

[19:20:07] LAH (voice-over): Paddock decided to retire in Mesquite, Nevada, a community of some 18,000 people, about 80 miles from Las Vegas. Police there is searching the home he shared with his girlfriend and finding some guns and ammunition, but few obvious clues about a motive.

OFFICER QUINN AVERETT, MESQUITE POLICE DEPARTMENT: It's a nice, clean home and there's nothing out of the ordinary.

(END VIDEOTAPE)

LAH: Well, certainly something was out of the ordinary as investigators laid out those numbers for us, 18 weapons found in the home. Several thousand rounds of ammunition and again, explosives found in the car in the form of fertilizer, Erin. There are going to be a lot of questions about this live-in girlfriend who's now in Tokyo. How much does she know, what does she know, and how she could have not known. Erin?

BURNETT: All right, thank you very much Kyung. And now, the former assistant director for investigations with the U.S. Marshals Art Roderick join us me along with former FBI special agent James Gagliano. Why?

JAMES GAGLIANO, FORMER FBI SPECIAL AGENT: What we found since really the first mass shooting in the U.S. you asked was August 1, 1966 at the University of Texas Clock Tower shooting. What we found is there's generally a process that happens. Somebody comes up with a grievance and targeted a particular group. Somebody that has (INAUDIBLE) and then there's a trigger event.

Now we know that the concert was basically announced last February. It looks like from the weapons that they found from the planning, from the execution, it looks like this plan was in place for a long time.

Because the number of weapons and now we're finding about other weaponry, what he planned to do with that, we don't know. I mean, you're talking about 16 guns in the hotel room, 18 in his home plus some scopes, tripods on the hotel room.

ART RODERICK, FORMER ASSISTANT DIRECTOR FOR INVESTIGATIONS, U.S. MARSHALS: That's something that struck me. It is the planning that went into this particular incident. I mean, I spent -- in my younger days I was a counter sniper with the U.S. Marshals Special Operations Group. And you not only had to be a good shot, but one of the things you had to do is pick the location to shoot from.

I think at some point he was standing in the middle of that parking lot where they had the concert and looked up and found the best location to shoot from. And he took the corner suite so that he had two different angles to shoot from. And he picked a distance of a quarter of a mile away so that the individuals that he was targeting, you know, he's shooting into a mass group, he wasn't picking any particular individuals off.

But it was confusing for them because they couldn't tell right away where the rounds were coming from.

BURNETT: I mean, because you're talking about here 300 to 400 yards away, across the street from where the actual concert was taking place right, James and he's shooting down. And he killed 59 people. He injured more than 500, you're talking 527 that we know of right now.

Is this -- and we don't know of any military history or anything, but he did have tripods. Is this someone who had training or is this just -- he just let a gun go.

GAGLIANO: It certainly somebody that was in possession of automatic weaponry. When I listened to the sounds this morning, the chilling sounds of those automatic weapons, he either obtained an automatic weapon illegally or he bought a semiautomatic weapon and then used a modification kit and illegally modified that weapon. He had -- I understand there were a couple of tripods there and as Art pointed out, the fact that he had two cornered window, broke them out and basically set up a killing field.

And the problem for the victims on the ground, it's so difficult to determine where the shots are coming from. Storme pointed out, your last guest, he could see the rounds impacting on the stage. The people at ground level had no idea. So instead of being able to run out of the killing zone, some of them might have been running back into it.

BURNETT: Or of course getting low which would be one of your first instincts and of course makes you in this case more prone.

UNIDENTIFIED MALE: Exactly. Yes.

BURNETT: So Art, when you think about what happened here in the planning, you're saying you actually think he may have selected even the event itself?

RODERICK: Yes.

BURNETT: There also would have been some breaking point, we didn't know what that might have been with the grievance was, what role if any his girlfriend who is now in Tokyo may have played. We do just do not know.

All we know is, our Drew Griffin just spoke to the neighbors of his -- he had a home in Florida, investment home that he sold in 2015. They said he was wealthy, gentle giant. His brother didn't seem to have any idea. We don't know anything except that his father used to be a psychopathic bank robber.

RODERICK: Right. And I mean, he has a very odd profile. You wouldn't think of this type of individual actually coming out and doing something like this. But to me there was a lot of planning that went into this. I think he left a note or something somewhere to describe what he's doing here because he knew once he started this he was either going to kill himself or law enforcement was going to kill him if they (INAUDIBLE).

BURNETT: And what about that? The miracle -- I mean, it feels like a horrible word to use but he could have killed and kept killing. They got to that room very quickly.

GAGLIANO: The new paradigm as we deal with terrorists whether they're domestic terrorists or international terrorists is this, they don't stick around for protracted negotiations anymore.

[19:25:03] It's not 1975 in dog day afternoon. It's literally let me kill as many as people as possible and I'm going to kill myself or await suicide by cop.

BURNETT: But they got in that room quickly is just something that you were talking at one point.

GAGLIANO: They did an amazing job. It was a dynamic entry. Not all SWAT teams, not all police departments are quipped with folks that are able to use explosive breaching, the use of explosive breaching to get inside. The subject obviously knew that the gig was up at that point in time and killed himself. But the speed, surprise (INAUDIBLE) and that critical fail-safe breach all worked in their favor in this instance.

BURNETT: They saved lives.

RODERICK: Absolutely. Yes, I mean, the interesting thing too about this whole negotiation issue, we talked about this during Orlando. Because that particular individual was negotiating so he had more time to kill more people. And that's exactly what we have to look at from law enforcement now, is how do we handle these types of situations because they're just stalling for time so they can get a higher body count.

BURNETT: All right, thank you both very much. So many questions tonight.

Security is beefed up at the hotels along this strip tonight. How did the shooter get 16 guns into his hotel room without anybody noticing?

And then into action, carrying victims to safety, applying makeshift tourniquets. So many people, heroes, one of our guests doing all of those things trying to save lives. We'll be OutFront.

(COMMERCIAL BREAK)

BURNETT: Welcome back to a special edition of OutFront. I am live in Las Vegas. Five hundred twenty-seven people right now injured, fighting for their lives. Fifty-nine people murdered in the deadliest shooting in modern American history.

We are learning new details tonight about the shooter, a, 64-year-old man. Police say they found 18 firearms, explosives, and thousands of rounds of ammo at the shooter's home near Las Vegas. They say they found ammonium nitrate in his car.

The motive, though, remains a mystery. They simply do not know. They have no answers on that, as to why he would suddenly come and fire on thousands, tens of thousands of concertgoers attending a music festival right across the street from his home or from his hotel, which, of course, is behind me.

Dan Simon is OUTFRONT in the Mandalay Bay, where the gunman launched the attack.

And, Dan, the Mandalay Bay has reopened. I was just there a few moments ago. What is the security situation there where you are?

DAN SIMON, CNN CORRESPONDENT: Right, Erin.

And we are told that security personnel have lifted all restrictions to the property, that means people can come and go as they please. They can go to their rooms. They can leave their rooms.

The same applies to all MGM Resorts. Now, we know that at least one casino in Las Vegas has stepped up security. We saw security personnel at the Wynn Resort. They were looking at bags as people were going into the hotel.

But, Erin, there are still questions about what happened, of course, at the Mandalay Bay. How did the shooter get all those guns up to his room, all 16 of them? Did he make multiple trips? Did he do it himself? At a certain point, did he put a "do not disturb" sign on the door? Those are going to be questions for investigators. Of course, still so many questions left unanswered, Erin.

BURNETT: So many questions, as I said. This is going to be a long investigation. They simply right now are trying to find out who to ask those questions of.

OUTFRONT now, the Las Vegas mayor, Carolyn Goodman.

Mayor Goodman, so sorry for what has happened here in your city. No words to describe what you are dealing with tonight.

MAYOR CAROLYN GOODMAN, LAS VEGAS: Thank you.

BURNETT: Mandalay Bay, I know, is trying to have -- yes?

GOODMAN: The entire community is just devastated by this. And, of course, the families that lost those 59 victims, we just can't even imagine how they are suffering.

BURNETT: Do you have any idea at this point, Mayor, any idea as to why this man did this, why he targeted this event?

GOODMAN: No, I don't think we've yet gotten that. The sheriff is going ahead with a thorough investigation. The killer came from a town nearby.

I understand he owned property there and another piece of property in northern Nevada. I'm not sure how long he lived there, but I did call my friend, the mayor of Mesquite, and he said he was unaware of the man, and that's a very small community because even here in Las Vegas, we know each other pretty well.

BURNETT: So, do you have any idea as to how he managed to do what he did, and by that, I mean, the latest we understand from the sheriff is he had 17 guns in the hotel room in the Mandalay Bay, multiple rifles among them, scopes, tripods, any idea how he was able to bring that into that hotel?

GOODMAN: Wherever you travel in the world, you travel with your bags. And if, in fact, you gone on an airplane, of course, you know, it's always searched.

Here, when you travel by car here or by bus or by rail, there is none of that. And all of us have to insist upon the freedoms to be able to take our baggage and go where we want to go. So I don't think there was anything, you know, that was suspicious. I don't believe there is the type of security that we have to go through at the airport.

And so, for him to take bags up to his room, just -- I'm sure just was no matter how many because people come here, they're entertainers. Some of our entertainers have a lot of bags. Then we have performers that come here. And I'm not sure they did anything but look at, you know, his signup credentials and his credit card.

But the reality, you know, having spent most of this morning, early this morning over at UMC and our number one trauma unit, and the confusion among those who had been shot at and had wounds, as to where the gunshots were coming from -- and first of all, there were gunshots at all, because, as you know, this was a great outdoor concert that was going on. It was in its third night and there were loud speakers and everything was so much technology today, really speaks out of explosive things happening and fireworks.

And so, the initial reaction -- and when I spoke to some of these patients was, they didn't know what it was or even where it was coming from, much less that it was coming from up on the 32nd floor of the nearby hotel.

[19:35:13] BURNETT: And, Mayor, of course, this is not something anybody would have ever thought would happen, as you just explained yourself, with the baggage or coming from the 32nd floor. No one would have ever thought of this happening. But now, it has. And there's fear. And you have tens of thousands of people coming here daily for conferences and concerts.

Do you think anything will change?

GOODMAN: You know, no, you know, what we found out from all of this is how unbelievably bonded and supportive our community is here. First of all, our first responders and law enforcement, oh, my heavens, they are so phenomenal. We had about 22,000 people at that site that night. They had been there for two days. And, of course, we had law enforcement there to make sure that the people that were coming to the concerts were legitimate and paid their fare coming in and were acting orderly, which, of course, they were.

And this is -- you know, western music. These are kids in cowboy boots and cowboy hats, and just out for a nice, good time and so many young people, but really and truly all ages.

And so, you know, when you have one crazed individual, and we've gotten phone calls and emails -- I mean, I can't tell you how supportive this country's been. And Buddy Dyer in Orlando, and my goodness, look what they went through with Pulse. And then, of course, from the Governor Malloy in Connecticut and Sandy Hook.

I mean, you look at --

BURNETT: Yes.

GOODMAN: -- crazed people that are bent on doing the most destructive things. And I think this town is very resilient. We have a wonderful community. Our law enforcement is absolutely unequalled.

I mean, they are so phenomenal. And our first responders -- and we have people who have come here from different counties in Nevada, as well as from neighboring states to help us. BURNETT: All right. Well, Mayor Goodman, I appreciate your time.

Thank you.

And next --

GOODMAN: Thank you.

BURNETT: -- ricochet all around them, but they survived. A couple who began the night enjoying like the mayor was talking about, a young couple enjoying the concert ended up running for their lives.

And many people did what they could to help, anything they could do to try to help people who were lying around them. My next guests didn't think twice before dragging strangers to safety.

(COMMERCIAL BREAK)

BURNETT: Welcome back to OUTFRONT.

We're live in Las Vegas after the deadliest shooting in modern U.S. history, right outside the Mandalay Bay behind us. Fifty-nine people dead after a gunman opened fire from the 32nd floor of that casino on people who were attending a country music concert, 527 people also injured.

At University Medical Center, which you just heard the mayor mentioned, right now, 12 people are fighting for their lives. They are in critical condition.

OUTFRONT now, one of the men who jumped into the action to save lives as the shots started to ring out for that interminable 10, 15 minutes, Brendan Hoolihan.

And, Brendan, we're so glad you're OK. Your family is OK. I know you were there with them and you had really wandered away to get something to drink, out of nowhere you heard the shots. What did you think when you first heard that noise?

BRENDAN HOOLIHAN, RESCUED INJURED VICTIMS: To me, it just sounded like fireworks. The people that I was with -- I was standing next to, we were all talking about, you know, why would someone bring fireworks to a show like this? And we started seeing flashing coming from Mandalay Bay and people just falling down. It was kind of set in that someone was shooting, an active shooter.

BURNETT: I know then your family, your mother, your aunt, your cousins were all with you. They went back to the hotel. They were evacuated and safely, but then you went back. What made you go back?

HOOLIHAN: Yes, I knew they were going to be safe. They were on the other side of the concert by the Malibu booth. I knew there was an easy exit out of the (INAUDIBLE), that they would be OK. The main thought that was going through my head was if my family was on that other side of the stage, I would want someone to treat them like the way I treated other people and, you know, go to their aid.

BURNETT: What did you see?

HOOLIHAN: Initially, when the first burst of gunfire came out. I ran through the house of blues, trying to get everybody to go through there, hopped a fence with one of the guys that I was with. We pulled down the fence because so many people weren't able to climb over the fence, so we just pulled on it so we could finally bend the metal on it.

And then we started seeing people running out with blood all over them. That's kind of when it set in, like, we need to do something right now because, you know, you don't want casualties. It is a big family venue. You know, everybody there is just so, so nice. So, it's just one of those things that you got to take them in as your family.

BURNETT: And I know you were trying to do everything you could with a makeshift tourniquet or trying to help people who were bleeding. As these people were running by, so many people injured. I mean, how many people were you able to help?

HOOLIHAN: I want to say anywhere in the ballpark of 14 to 16 that were at least hit with gunshot wounds. I know we had a girl with a broken ankle that we helped get into the parking lot.

[19:45:06] And at first, it was just me and this other guy, and another guy joined us, so we had -- it was just the three of us, and we were able to pick people up and carry them.

And we were meeting people in the parking lot that had vehicles ready and running through this (INAUDIBLE) to get them out of there and to the hospitals. As far as the tourniquets go, just from training, I received prior, we were grabbing clothing and, you know, breaking metal legs off chairs just to tie it around someone, just to get it on them. And we couldn't find something strong enough, we'd just tie it as tight as we could and have someone stayed away (INAUDIBLE).

BURNETT: Well, Brendan, thank you very much. I know there are many who are grateful for what you did and others like you who tried so much to help people and save lives. Thank you.

HOOLIHAN: Thank you.

BURNETT: And next, police are getting ready right now. They're going to raid a second home belonging to the shooter as they're trying to understand exactly what he was planning. It seems like he had much, much more in terms of his arsenal and why.

And a nurse, police department employee, and teachers, we're going to honor the memory of those who were killed in this attack.

(COMMERCIAL BREAK)

[19:50:18] BURNETT: Breaking news, we now know the gunman who killed 59 people and wounded 527 more in the Las Vegas Strip outside the hotel behind where we are standing had a massive arsenal. Thousands of country music fans were running for their lives when the gunman opened fire from the 32nd floor of the Mandalay Bay Casino behind us.

Officials say they found 17 firearms in his hotel room. More than 18 additional firearms, as well as explosives and several thousands of rounds of ammunition were found in one of his homes near Las Vegas, in Mesquite. Plus, ammonium nitrate, which is a fertilizer that was found in his vehicle and an explosive called Tannerite in his home. That's what we know in that home.

Right now, a SWAT team is actually preparing to enter another one of the shooter's properties, this in Reno.

Art Roderick and James Gagliano are back with me.

This raid, as we understand, about to happen in Reno. We know about the one home, 17 firearms, fertilizer, ammonium nitrate and now they're about to go into another one.

JAMES GAGLIANO, FORMER FBI SPECIAL AGENT: Absolutely. And they have to assume the house has been booby trapped. Somebody like this had -- was in position of ammonium nitrate and Tannerite, that's somebody that could make a pipe bomb or do something to booby-trap the house.

I believe the police in this instance will not use a dynamic (INAUDIBLE). They'll do a slow and methodical law enforcement clear for their safety and security because remember, they're not looking to start more loss of life and they'll probably use a robot.

ART RODERICK, FORMER ASSISTANT DIRECTOR FOR INVESTIGATIONS, U.S. MARSHALS: A robot, right. That's what I was thinking --

BURNETT: A robot to go in because you also think it's possible at this location --

RODERICK: They have to assume that. Ammonium nitrate is what Timothy McVeigh used in Oklahoma. You saw the damage that could be created for an explosive like that. So, yes, they are probably going to use robots, they're going to use other means, and they can take the time on this. They don't have to execute this quickly.

BURNETT: What about the timing, again, we just don't know the motive, which is obviously going to be crucial.

But, James, when you think about the stuff in his vehicle, they found all this ammonium nitrate, but he had not turned that into an explosive and he -- it's almost as if was he planning on this not about event? He was suddenly motivated to act more quickly or does it make sense?

GAGLIANO: Your preface to that question was perfect. It's spot-on. We don't know a motive. That's what they're going to look for in the house.

RODERICK: Right.

GAGLIANO: They're going to search for a manifesto. They're going to search for something he's either written, something he's been online with. They're going to go through his digital exhaust. And what did his cell phone say? What did a laptop say?

What would -- maybe there were handwritten notes underneath his bed. So, it's going to start out and be clear to make sure that there are no other weapons or anything else to hurt somebody. The next phase is going to be a painstaking crime scene where they're going to go through and harvest evidence.

BURNETT: And they're hoping that this location is going to be (INAUDIBLE) would fester something. They just don't know. They don't seem to have gotten --

(CROSSTALK)

RODERICK: I just can't imagine him planning all this, going through this, looking at the plans, establishing this as his target and not writing anything down. I think they're going to find something either in the house in Mesquite or the house here.

BURNETT: So, because what we understand at this point is, he didn't have a military background. He didn't have a criminal background. There's no evidence at this point. We don't know of any kind of sense of gun training.

There's nothing that would indicate it fits a profile of anybody we've seen before, history of illness or anything that we are aware of.

GAGLIANO: Sure. And he's 64 years old which puts him just to the outside of really where we find the age to these folks. But, again, you're going to look for somebody that might be politically motivated? Sure. The definition of terrorism, it is violence or intimidation, threats of (INAUDIBLE) in pursuit of political aims or social aims.

So, he just could have been disgruntled but there's always a component of mental health. This was not a stable individual. It was a depraved maniac.

BURNETT: And what do you think the significance is? We talked about the explosive a moment, Mike, in his vehicle, which means he had gotten it here?

RODERICK: Exactly.

BURNETT: All right? But not yet taken it to the next step.

RODERICK: And Tannerite, too.

BURNETT: Right.

RODERICK: I mean, when you look at both of those, what was he planning to do with that?

BURNETT: The Tannerite, of course, we clear was in the home in Mesquite.

RODERICK: In the home, right, but I mean, you put all this together and you got somebody, possibly has a bomb factory, was trying to make an explosive device. You know, was that car going to be used as a bomb, did he have enough time, was he going to shoot into the vehicle to try to explode, you know, the ammonium nitrate in the car? So, this is all going to be sorted out maybe because the response by law enforcement was so quick.

BURNETT: Do you think anybody else knew anything?

GAGLIANO: That is something that is absolutely in the forefront of the investigators' mind right now. First of all, they got to find out if anybody else knew of it because they are an adversary, and also from a human intelligent standpoint. What can we tell them about something potentially happening going on down there?

[19:55:00] RODERICK: This is why they want to question the girlfriend so badly.

BURNETT: Right. And as we know, she's in Tokyo right now. We don't know anything about why the state of their relationship or anything, which obviously could be very crucial as well.

Thank you both very much again.

And next, a woman described as a loving kindergarten teacher. She's among the 59 people dead tonight. We remember the victims.

(COMMERCIAL BREAK)

BURNETT: Fifty-nine people were killed in the Las Vegas attack. We want to remember the first victims who have been named as we are just starting to learn the names of people who lost their lives.

Sonny Melton was a nurse from Tennessee and just got married. He was 29 years old. His wife is a surgeon who survived the attack. She says he saved my life but at this point I can barely breathe.

Jenny Parks was a kindergarten teacher. She was from Lancaster, California. A relative say she was truly one of the most loving people you could ever hope to meet. She always went out of her way to help anyone. Her husband was one of the 527 injured.

Rachael Parker, she was a ten year veteran at the police department in manhattan Beach, California. She survived the initial shooting and died in the hospital.

Sandy Casey was a special education teacher at a middle school in Manhattan Beach, loved by students, colleagues. The school board president says we lost a spectacular teacher who devoted her life to helping some of our most needy students.

And Angela Gomez, we just learned her name, described as a fun-loving, and sweet young woman. She was an academic honor student at Riverside, California. She really did have her whole live ahead of her.

And Susan Smith, she was a wife, a mother and office manager at an elementary school in Simi Valley, California. Always welcoming, we are told, and always smiling.

Thank you for joining us.
