[22:00:00]

UNIDENTIFIED MALE: This is CNN breaking news.

DON LEMON, CNN HOST: This is CNN Tonight. I'm Don Lemon.

We are live in Las Vegas. Here's our breaking news. Investigators piecing together clues to the worst massacre in modern American history. And what we're learning is stunning.

New photos from inside Stephen Paddock's hotel room at the Mandalay Bay right behind me. The photos obtained by the Daily Mail show a luxurious room scattered with guns and ammunition.

And in one what police confirm tonight is the lifeless body of the shooter. Police also just minutes ago, releasing body camera footage showing officers responding as bullets rain down.

(BEGIN VIDEO CLIP)

UNIDENTIFIED MALE: Get them down. Get them down. Hold your fire. Go that way. Get that way. Get out of here there's gunshots from over there. Go that way. Go that way!

At this point they're just trying to figure out where the rounds are coming from.

UNIDENTIFIED MALE: Go that way, go that way.

UNIDENTIFIED MALE: They're shooting right at us, guys. Everyone stay down.

UNIDENTIFIED MALE: Get down, get down on the window.

UNIDENTIFIED MALE: Good couple of officers hunkered down next to patrol vehicle. One Las Vegas (Inaudible).

UNIDENTIFIED MALE: Get back! Get back!

UNIDENTIFIED FEMALE: Get back!

UNIDENTIFIED MALE: This video is obscured. Those yellow reflective vests, those are what you're actually seeing.

UNIDENTIFIED MALE: Everybody, get down, get down, get down.

UNIDENTIFIED MALE: Very difficult to tell from that video, but the officers actually standing over another woman.

UNIDENTIFIED MALE: Get down, get down.

UNIDENTIFIED MALE: I have a vest on.

UNIDENTIFIED MALE: What do you say I have a vest on?

UNIDENTIFIED MALE: This way, this way. Go, go, go. That way, that way. That way.

(END VIDEO CLIP)

LEMON: It's really unbelievable. Our law enforcement analysts are standing by live here in Las Vegas. But first I want to get the latest on the investigation now.

CNN's Kyung Lah joins me on what we heard from investigators, holding that press conference, releasing that body cam footage. Kyung, it is stunning. We know the first 911 calls started at 10.08 according to investigators. The shooting went on for 9 to 11 minutes. You see in that video the unthinkable becoming real to first responders and concertgoers. What else do we know?

KYUNG LAH, SENIOR U.S. CORRESPONDENT, CNN: What we know is that there were a dozen or so volleys and that's really extraordinary. If you think about those responding officers, they were forming of on their own. These were officers already working that event. That's why they're wearing those yellow vests. They were, you know, trying to help out on the job, keeping the public safe there.

And then they formed up on their own and they started up in the face of all of that gunfire, a dozen or so volleys, they started to approach. The key that top law enforcement there did say is that the shooting stopped sometime 9 to 11 minutes, about 10.19 or so they say the shooting stopped.

So, he said, and I'm going to quote him here, think about that, "with all that firepower they were able to stop the shooting quickly."

[22:04:59] What we still don't know, Don, is exactly when SWAT reached the door, that he said that they will be working still on those fine details and trying to release that information as soon as tomorrow, Don.

LEMON: Let's talk about the cameras that we also learned today, Kyung, I believe in a press conference they said that the shooter had two cameras in the hallway, one in the peephole so that he could see down the hall and see who was approaching.

LAH: The key here is, why did he have those cameras. And what we heard earlier in the day and then in that press conference as well, is that they believe, that law enforcement believes the reason why those cameras were set up is not for broadcasting purposes.

We haven't found any video on social media. It was so he could watch law enforcement approach, the peephole, so he could see law enforcement down the hallways. Those cameras simply to see law enforcement approaching. And so for what purpose and clearly that first incident he had, where he first faced off with law enforcement, he did exchange gunfire with law enforcement, there was a security guard who was shot. So, all of this weaves into the preparation that this man took.

LEMON: And Kyung, tonight new pictures and video of Stephen Paddock's hotel room showing just some of those guns that he had with him. In this photo, this one is obtained by Daily Mail, confirmed tonight by Las Vegas Metro Police. You can also see Paddock's body. Explain this photograph to us.

LAH: What you're looking at is shortly after law enforcement was able to enter that room. What we do know is that law enforcement says that the gunman took his own life. That's what you're seeing a portion of his body that law enforcement did confirm for us. The law enforcement did confirm for us.

But the frightening things that you see thrown amid that hotel room, are the number of guns and a number of spent shell casings. It is extraordinary. I mean, we already get a sense from the sound of all of those bullets that were hitting the crowd, they were flying into the crowd. But when you see just in one small snapshot, the number of shell casings on the floor, it is simply, simply bone chilling.

LEMON: Kyung Lah with the latest on the investigation for us this evening. Kyung, thank you very much.

More and more clues tonight, but what does all of this tell us about the shooter and his motive? That's the big question here what was the motive here and why did he do it.

I want to bring in now forensic neuropsychologist John White, who is a former detective and as has mass shooter database, has a mass shooter database, CNN law enforcement analysts, Art Roderick and James Gagliano.

My goodness, guys. Art, I'm going to start with you.

ART RODERICK, LAW ENFORCEMENT ANALYST, CNN: Yes.

LEMON: When you listen to that firepower, I mean, that is war zone. That stuff of war zone.

RODERICK: That's absolutely war zone. And he had three levels of weapons in that room. He had a handgun, he had shotgun, which was for close-in confrontation, he had medium range weapons. The .233 that you saw lying on the floor. That had the stuck on it that made it an automatic weapon, and then the high powered long distance weapons that were monitor, two of them on the bipod. So, I mean, he was ready for long distance, medium range and short range.

LEMON: Look at this picture. What is this, I guess a piece of furniture.

RODERICK: Yes. You see that there is a .233, it looks to me like a .223.

LEMON: The one in front of the piece of purple furniture.

RODERICK: To the left.

LEMON: Right.

RODERICK: And it's got the extended magazine. It also has a front grip that you can convert into a bipod. But that's a medium range weapon.

LEMON: OK, and the one.

RODERICK: The one on the right is the one I'm talking about. Its model on the bipod.

LEMON: OK. Hold on, one at a time.

RODERICK: That is a sniper. Yes.

LEMON: This one that we see right here.

RODERICK: That on the floor right there looks like a .233 to me.

LEMON: Next to the purple furniture.

RODERICK: Next -- right. Right there, and it's got a red dot scope on it...

LEMON: How far...

RODERICK: It's got extended magazine.

LEMON: What's the range?

RODERICK: The effective range is usually to about 400 yards.

LEMON: OK.

RODERICK: The weapon to the right, which is the bipod, there's two of them there, there are bipod mono weapons.

LEMON: Right.

RODERICK: Those look to me to be like a .308 into a sniper configuration with a regular scope that we usually see on hunting rifles and that thing can reach out to a 1000, 1200 yards.

LEMON: So it's most likely that the one on the right is the -- it wasn't, was it -- the one on the left couldn't reach that far, could it?

RODERICK: It could reach the middle of the parking lot because it's about 400 yards from his window to the middle of the parking lot. And he's not trying to pick out individuals with that.

LEMON: OK.

RODERICK: He's just spraying into the crowd.

LEMON: OK. So, James, let me bring you in here and talk about 9, 11 minutes, 10.08 to 10.19, 20 volleys. What is that? Explain that.

JAMES GAGLIANO, LAW ENFORCEMENT ANALYST, CNN: Well, Don, if you look at the picture of the suspect splayed out on the floor there, you notice he's wearing gloves.

LEMON: Right.

GAGLIANO: And that's because those barrels, those types of automatic weapons that Art was describing, those things cycle 750 to 900 rounds a minute. So, as he moves back and forth between shooting positions barrels would probably heat up.

I think another important thing here is understanding that, again, from that 32nd floor, Don, he was using plunging fire, which means indirect fire. Because Art pointed out, those weapons the maximum effective range is 550, 400 or 550 yards. But that's a direct fire.

RODERICK: Right.

GAGLIANO: They're also the bullets will reach out to 3,600 meters. So if you shoot them up in an indirect fashion as he was doing plunging fire and then it comes down on the crowd exactly, you're shooting in an area, you're not shooting at one person.

[22:10:07] LEMON: So that's why they said it was raining -- it was like raining fire and raining bullets.

GAGLIANO: Raining fire.

LEMON: OK. Let me ask you a little bit more before I get to doctor. Twelve bump fire stocks.

GAGLIANO: Yes.

LEMON: Explain that.

GAGLIANO: OK. So, you can mechanically reconfigure a firearm. It takes a kit to do that. And you really don't have to have to be an armor, professional armor to do that. Now what's interesting was the ATF special agent in charge mentioned in the press conference, those bump stocks are not illegal.

Because there's nothing -- it's not a modification of the weapon. You're sticking it in so it keeps the weapon firing. But it's just a stick.

So, now, when he puts those things in there and it fires I think that what happens was some of those weapons jammed and that's you have the delays as he was moving in between positions and changing weapons out. LEMON: All right. So, Dr. White, as you listen to this, as you look

at these pictures and you listen to the body cam footage, what do you think of this? What do you make of what happened?

JOHN WHITE, FORENSIC NEUROPSYCHOLOGIST: Well, obviously a lot of anger, a lot of preparation. This is very organized. This is not someone who's a mad man who went out and just impulsively did all this. He's had years of planning and preparation for this. He's getting back at somebody. This is an anger retaliation-type behavior.

LEMON: You heard the brother say he's the last, one of the last people I expected to do that, I'm paraphrasing. And also saying it's like an asteroid falling from the sky.

WHITE: Right.

LEMON: But according to law enforcement over 20 years, and you said that last night that he was a collector...

WHITE: Yes.

LEMON: ... he probably started.

WHITE: Right.

LEMON: Over 20 years collecting guns. Family members never saw that? There were no clues in 20 years.

WHITE: Well, there are a lot of guys that live two lives. I mean, they have their public life and a private life. In a private life is full of fantasies. Fantasies of violence that they just haven't had a precipitating event to push him over the edge yet.

And I think that's what law enforcement will probably find when they do their investigation. They're going to find something that pushed him over the edge.

LEMON: What about his dad and his dad's history as a bank robber?

WHITE: Yes.

LEMON: That's not a determinative or a factor in this.

(CROSSTALK)

WHITE: Well, we don't know yet but it certainly could be. I mean, he was young, that was his formative years when his dad was most wanted in the FBI list. So there could be some self-esteem or just anger at the government, anger with anything at that point.

LEMON: Yes.

WHITE: And I think one other -- being a neuropsychologist, I also really hope that law enforcement and the autopsy really looks that bring behavior and sees -- you know, Charles Whitman climbed upon the University of Texas tower back in 1966 and it shock most people and they found out that he had a tumor. Now, that's no excuse. Don't get me wrong, that's no excuse. This is a hard behavior pattern, but it might help us understand.

LEMON: Yes, let's talk about his companion.

RODERICK: Yes.

LEMON: You know, there's a report that we read tonight about him possibly being abusive. Again, that's reporting. But what are they looking for from his companion. They're bringing her back. They don't think she was involved, but also reports about money that was asked at the press conference about money being wire.

RODERICK: Right. I mean, she's been up and down as a person of interest and not a person of interest.

LEMON: Right.

RODERICK: I think now they realize, hey, we really have to sit down and debrief her. I mean, to me, she's the key to finding out what this, what was going through his head in the past few months. You know, we don't know when she left, we don't know why she left. We know that there was money transferred to the family before in a couple different amounts but it seem like a fairly large amount of money. That's interesting, too. I mean, is this sort of his will here.

LEMON: Right.

RODERICK: There's some money I'm going to take myself out.

LEMON: Yes.

RODERICK: What was that payment for? So there's a lot of questions hopefully she'll be able to answer.

LEMON: Yes. And we have to remember also, James, that law enforcement they run into this. Everybody else is running away. Also off-duty officer Charles Hartsfield...

GAGLIANO: Yes.

LEMON: ... was talked about at this press conference and the undersheriff just broke down.

GAGLIANO: Don, what we've seen is post-Columbine in 1998. We've seen that the first responders, it's never going to be a homogenous unit. It's going to be a mix matched of folks that are full of their heraldry and courage and bravery.

LEMON: Yes.

GAGLIANO: And they've got to put together a hasty plan. What ended happen here is once the shooter stopped shooting and you knew that there wasn't a hostage involved, now you've got to dial back and put together a deliberate plan. And that's why you've that hour and 15 minutes before you had the tactical team making entry. That a homogenous tactical team as oppose to the brave folks that got together and just went to stop the shooting.

LEMON: Yes. Then of course our hearts go out to the family of everyone involved and the police officer who risked his life and gave his life to save other people.

Thank you so much, gentlemen. I appreciate that. Much, much more. We're going to have more on that video, the body cam video and also on the pictures that were taken on this massacre. I'm going to ask a Nevada congresswoman what she has learned.

Plus, new developments in the Russia investigation to tell you about. What CNN has learned about which voters in which states were targeted by the Russians on Facebook?

[22:15:04] (COMMERCIAL BREAK)

LEMON: We're back now live in Las Vegas with our breaking news. Police tonight saying shooter Stephen Paddock purchased guns in four states. Law enforcement officials telling CNN he had been accumulating those guns for more than 20 years.

And police believe he acted alone, but they still don't know his motive. That's a big question here.

Releasing body cam video footage from the shooting a little less than an hour ago. Watch this.

(BEGIN VIDEO CLIP)

UNIDENTIFIED MALE: Go that way.

UNIDENTIFIED MALE: There's gunshots right here.

(END VIDEO CLIP)

LEMON: Congresswoman Dina Titus, a Nevada democrat joins me now to talk about the latest on the investigation. Congresswoman -- Representative, thank you very much.

DINA TITUS, (D) UNITED STATES REPRESENTATIVE: Thank you.

LEMON: You look at that video and you hear it, it's unbelievable what they were up, the firepower that they were up against.

TITUS: It was just raining down on them. And what was so scary they didn't know where it was coming from. Thankfully there were some officers there and some off-duty policemen who helped locate that it was coming from above.

LEMON: Yes. As I understand they've been really transparent, by the way, releasing this. Are you surprised that they released so much, and right, and gratefully so, I think.

[22:20:03] TITUS: Well, absolutely. This is my district, and so we want to know what's going on. We respect them for keeping some things back until they know for sure. LEMON: Right.

TITUS: But they've had periodic press conferences. They're working closely with the fire department and the FBI. It's a really good coordinated effort.

LEMON: And their stretch. They're stretch.

TITUS: No question.

LEMON: Yes. You mention the FBI. You've been getting FBI briefings. TITUS: Yes.

LEMON: Is there anything you can share with us that you're learning from those briefings?

TITUS: Well, probably nothing that you don't already know. The main thing is that they are bringing back the girlfriend. They want -- that she's a person of interest. We'll see if she can shed any light on what his motives were, and also they're looking into that $100,000 that was wired to the Philippines.

LEMON: They were asked about that in the press conference. I think it was the undersheriff or someone from the FBI said that they -- I was just listening on audio, not on television, saying that they had financial warrants out...

TITUS: Yes.

LEMON: ... but they couldn't confirm it at this point, but they are trying to figure out that part of it out, correct?

TITUS: Why send the money, where, when if there's any connection.

LEMON: OK. I want to talk about, this is the president tweeted this tonight. He said, "It's a miracle how fast the Las Vegas Metropolitan Police were able to find the demented shooter and stop him from even more killing."

He was referring to comments today at what happened in Las Vegas was a miracle. Because he said it was a miracle.

TITUS: Yes.

LEMON: I know that you were standing behind the sheriff, and Sheriff Lombardo when he talked about the first responders.

TITUS: Right.

LEMON: And the sacrifices they made. Tell me about that.

TITUS: Well, it's absolutely true. I think they saved hundreds of lives because of their coordinated effort. They work with the Fire Department. They work with security. You know, Las Vegas has the best private security of anyplace in the world. So Mandalay Bay security actually helped them to identify where the shooter was and lead them to the room where he was located.

LEMON: Do you think security or the way people are protected here, do you think that should change?

TITUS: Well, we have had a target on our back for a long time, but we were soft targets like News Year's Eve or the racetrack or concerts. Now I think we'll look at considering them more like hard targets.

LEMON: I've got to ask you this question. So much has been made of what should happen now when it comes to guns and whether what type of guns should be available to citizens? Some have questioned the appropriateness of talking about it now and saying that it's a political issue.

TITUS: Right.

LEMON: Where do you stand on that?

TITUS: Well, those questioning the appropriateness of the time and never do something on it. We've got hundreds of phone calls saying we've got to do something about this now. First it was children and then the congressman himself and how many other shootings. When are you going to do something? And so, I think the time is right. We grieved, we mourned, we did that yesterday. Now let's get to work.

LEMON: You're doing something with the bump.

TITUS: Exactly. You know, that is just huge loophole that allows you to convert a weapon to something that's like an automatic gun. And so, Congressman Cicilline from Rhode Island and I will be putting in a bill to outlaw those kits.

LEMON: So that they can't be used the way that they were used the other night with the bump fire stocks.

Thank you so much, Congresswoman.

(CROSSTALK)

TITUS: Thank you. Thank you for being here and telling our story.

LEMON: Thank you very much. We'll learning much more tonight about some of the 58 people who lost their lives in Sunday massacre.

Heather Warino Alvarado was a three -- was a mother of three married to Cedar -- to city of Utah firefighter Albert Alvarado, and was happiest when she was traveling with her family.

Michelle Vo was also a victim of this massacre. She worked for New York life insurance in their greater Pasadena office. Kurt Von Tillow was a father and grandfather from Cameron Park, California. He was a 55-year-old truck driver who owned his own businesses. And some members of his family were with him during the shooting and were hospitalized. His wife, his daughter and son-in-law escaped unharmed.

Fifty-six-year-old John Phippin was also killed. He was with his son Travis who was wounded in the arm when he stopped to help someone during the shooting. John stayed with him and he shouldered a woman from a bullet which ultimately led to his death.

[22:25:00] (COMMERCIAL BREAK)

LEMON: We've got much more ahead here in Las Vegas on the worst mass shooting in recent American history. I'm going to talk to FBI and ATF agents about the new reporting we have on the killer's arsenal.

But we also have breaking news tonight on the Russia investigation. We're learning that some Russian linked Facebook ads specifically targeted Michigan and Wisconsin, two states crucial to Donald Trump's victory last November. That's according to four sources with direct knowledge of the situation.

I want to bring in now CNN's Dylan Byers, and also national security analyst Juliette Kayyem. Let's starts with the reporting first. Dylan, you have this new reporting tonight on this Russian-linked Facebook ads. What are you learning?

DYLAN BYERS, SENIOR MEDIA AND POLITICS REPORTER, CNN: Well, Don, sources tells CNN that at least some of these Russian bought Facebook ads during the 2016 campaign were targeted at the states of Michigan and Wisconsin. Not just some of the ads targeted a key demographic group.

Obviously, both of these states were crucial in the 2016 campaign. You remember Donald Trump won Michigan by just over 10,000 votes. He won Wisconsin by just over 20,000 votes. It was within a 1 percent margin in both states.

So, the fact that some of these ads were targeted to those states is going to be something that Senate and House intelligence committee members are going to be looking at amid this ongoing investigation.

We have also learned that among the ads some were targeted towards audiences that would be susceptible to an anti-Muslim message. And those ads pushed an anti-Muslim message.

Pull back, larger picture, we're talking about a level of sophistication, of strategy on the part of this Russian ad buyers, understanding how they can influence American politics, understanding how they might be able to influence the 2016 campaign.

[22:29:57] LEMON: Dylan, do we know if the Russians were helped in choosing where to target?

BYERS: We don't. And that's something that investigators not just on the Hill but of course the special counsel Robert Mueller are looking into. The big question here, was there any sort of collusion between the Trump campaign and these Russian ad buyers?

Did one help out the other in terms of the targeting? If that's something that special investigate -- the special counsel finds, obviously that's a bombshell, Don. What we know now is that the ad buys, and these were over 3,000 ads

reaching over 10 million Americans during the time of 2015 to 2017. They were geared at sewing discord, basically amplifying the chaos that has been the reality of the American political landscape for well over two years now.

But the fact as part of that campaign you had ads like these targeted at key swing states in the lead up to the election. The fact, as we've reported earlier, that you had Black Lives Matter ads targeted towards cities like Baltimore and Ferguson, Missouri.

Obviously there's a level of strategy here that understands the political landscape, understands how to exploit it.

JULIETTE KAYYEM, NATIONAL SECURITY ANALYST, CNN: Yes.

BYERS: And when you talk about those swing states, you start talking about potentially a real effect on the 2016 election.

LEMON: Juliette, Michigan and Wisconsin, obviously two states that Donald Trump unexpectedly carried on Election Day. What's your reaction to this new reporting?

KAYYEM: I think it's significant because we need to take a step back. There's this sort of theory out there that the Russians wanted Trump and didn't want Hillary and did all these sort of, you know, crazy things to sort of interrupt social media.

I think Dylan's reporting and CNN's reporting tonight shows what we've kind of suspected for a little bit which is that this was a targeted kill. This was not just throwing a lot of things at the wall. This was Russia choosing two states, which were significant and known as swing states to, as Dylan says to create discord.

But what I want to remind people, discord leads to voting. I mean, in other words, it's not just discord. Why Trump won is because his base came out much stronger than I think Hillary Clinton's campaign assumed. So that the discord actually leads to voter turnout. It has a voting implication.

The $64,000 question is the fact that the Trump campaign strategy was the same as the Russian strategy, is that a coincidence, or is that the piece of this sort of growing collusion issue that we've been talking about for several months?

But the long and short of it is Facebook was used. And they've admitted it as weaponized. We don't know what they're going to do to stop it next time quite yet. But Russia's sophistication was directly targeted at a bulls eye towards Hillary Clinton and I think this proves it once again.

LEMON: Juliette Kayyem and Dylan Byers, thank you so much. When we come back, the ATF saying tonight a total of 47 firearms have been recovered from three different locations all belonging to Stephen Paddock. We're going to get more details on this deadly arsenal, that's next. [22:35:00] (COMMERCIAL BREAK)

LEMON: Breaking news. Police have recovered a total of 47 guns from shooter Stephen Paddock's hotel room and his home in Mesquite, Nevada, and also one in Reno, Nevada. They also turned up loads of ammunition.

I want to bring in now CNN senior investigative correspondent Drew Griffin. Drew, officials announcing tonight a total of 47 different firearms has been recovered. What more did we learned tonight. Do we know how he acquired these weapons?

DREW GRIFFIN, SENIOR INVESTIGATIVE REPORTER, CNN: Apparently, he'd been acquiring it, Don, for years, like many, many years. It didn't, you know, come to anybody's attention. They were all apparently so far at least legally bought. Keep in mind that this person, this killer had no criminal record, had no history of mental illness therefore was completely legal to buy weapons in this country, and Don, he bought a lot of them.

LEMON: Yes. These photos of the gunman's hotel suite, I mean, it's just unbelievable when you look at the fire power. They were acquired by the Daily Mail, by the way, show a truly shocking number of guns, Drew. What can you tell us about these weapons?

GRIFFIN: Well, and also what we heard from the ATF spokesperson tonight that one of the weapons -- and I don't know which pictures you have up right now -- but you can clearly see an aftermarket thing called a slide stock or bump stock.

According to the ATF 12 of these long firearms have this bump stock on it, which is a way, Don, legally - legally to basically turn these automatic, semiautomatic weapons into machine guns. So, as long as he had the ammunition, which we can see that we did. He had this big banana clips in there and other clips and these bump stocks, he could modify that gun and just shoot as if it were a machine gun.

And that may be surprising to learn for many people that you can do this. We actually have video that we see online from a manufacturer that shows you. And I'd like to just show this to your viewers so you can see this is legal to own in the United States.

Now, that to me, Don, that looks like a machine gun, it behaves like a machine gun. But according to the ATF it is legal because it doesn't change the dynamics or the mechanics of a gun. It's one of the loopholes or work around that you have the congresswoman on saying she is going to try to attack. But right now those are legal, and they were used in this massacre.

LEMON: It is unbelievable. Drew Griffin, I appreciate that reporting.

When we come back our experts who spent years - years working for the FBI and ATF, they're going to weigh in on all of this. We're going to break down everything we know about Paddock's weapons cash.

[22:40:00] (COMMERCIAL BREAK) LEMON: Breaking news, police recovering 47 firearms connected to Stephen Paddock. Sources telling CNN he accumulated guns for more than 20 years.

I want to bring in Chris Swecker, former FBI assistant director for the criminal investigative division. Jim Maxwell is also here, he is a retired FBI special agent. And Sam Rabadi is a former special agent in charge of the ATF in Philadelphia. First, Sam, sine you're here, ATF, that's your specialty, as you look at these pictures and these weapons tell us about it.

SAM RABADI, ATF SPECIAL AGENT IN CHARGE: Well, one of the first things that jump out at me and I believe is the second photo in the series of the three were the number of magazines that were stacked up. I'm not sure if you have it up on your screen just yet. But where the purple pillar is in the middle, you can just see the stack of a SureFire magazines. I believe that's what they are.

And essentially those magazines can hold up to 100 rounds. It was very telling to me, because if not but for the, just the absolute heroic actions of that tactical team, I believe Mr. Paddock probably intended to spend quite a bit of time just shooting into the crowd.

[22:45:03] And essentially with all that ammo, he could have gone on for quite a long time. Thank God that tactical team was able to get in there and the police be able to stop what was going on. Otherwise we would have had a much, much higher death toll.

LEMON: You know, police say, Jim, that they also found several pounds of ammonium nitrate in the gunman's car. Explain to our viewers what ammonium nitrate is used for in this context and why it would have been left in his car.

JIM MAXWELL, RETIRED SPECIAL AGENT, FBI: Well, there are one of two reasons here. Ammonium nitrate are both explosives. And if there were other paraphernalia, timers, vessels to contain explosives, wires, electrical sources, then I would say maybe he's dabbling in building a bomb.

But a guy who's an avid shooter, especially practicing shooting at great distances, would use a mixture of ammonium nitrate and other chemicals to build what they call an exploding target. And this is a very common thing among people who are avid shooters, especially shooters who are testing their weapons or sighting their weapons at great distances.

LEMON: I want to ask you about this bump stock.

MAXWELL: Sure.

LEMON: I want to ask about this bump stock and our Drew Griffin had some video from earlier where he showed something online. And there it is right there. And so it takes a semiautomatic weapon and then it turns it basically into an automatic weapon.

But according to Drew Griffin, but it's legal because it doesn't change the configuration of a weapon. They recovered I think it was 12 of these. How do they work? Can you explain that, Chris?

CHRIS SWECKER, FORMER FBI DIRECTOR: Well, best I can tell is it uses the recoil itself to simulate a weapon on auto fire. And, you know, it's legal because your finger is on the trigger, and your trigger finger is actually operating the weapon. It's a technical explanation. I heard the ATF as they explain it. I think it's a distinction without a difference as far as I'm concerned. As far as I'm concerned it's an automatic weapon.

LEMON: Yes, and it would appear from all intents and purposes it is. But, Chris, I want you to also look at -- go ahead. Did you want to talk about that? No.

Sure. Yes.

LEMON: So, Chris, I want you to look -- so let's look at some of the body cam video that we had earlier. We can put that up. This is from the press conference. And they played this. Let's listen to this a little bit.

(GUNSHOTS)

UNIDENTIFIED MALE: Go that, go that way, go that way.

(END VIDEO CLIP)

LEMON: So, Chris, what did law enforcement do right here? It looks like they were standing behind concrete walls.

SWECKER: Sure, they're trained to get behind cover as opposed to concealment. Concealment is OK, but cover is much better. That's something that will stop a bullet or at least slow down those types of rounds. They know to get behind the engine block of a car, behind a wall.

I notice in these videos they're all behind some type of good, solid cover. I mean, they are -- they are helping people and they're trying to get them behind the cover as well. Of course fog of war, it's chaos. They're all trying to figure out where the shots are coming from. But their training kicks in. You can tell that, you know, the law enforcement has the response that they have to get behind that cover.

LEMON: Sam, CNN learned tonight that the gunman despite the massive arsenal apparently wasn't a big gun enthusiast even though 20 years or so or more he collected them. The owner of the Reno, Nevada gun shop told us that, quote, "he didn't seem to know his way around a firearm. He didn't have the basic knowledge at the time and seem fairly unenthused by firearms."

Could someone make all these modifications without being a gun enthusiast or having some sort of expertise?

RABADI: I don't believe so. And I'm not sure how the gun storeowner saw that. For somebody who's owned these types of firearms for 20 plus years and to accumulate that many firearms and to be able to have the modifying placed on those guns and to be able to fire those weapons, you know, it's going to take a little bit of practice using the bump fire stock on those weapons, to be able to control it. That means he had to have possibly gun out to a range somewhere and practiced over and over again.

[22:50:05] So, you know, I don't necessarily agree with that. You know, he may not have wanted to tip his hand when he was going into these gun stores. But having something like these weapons for this period of time, I would say you have to have a pretty decent knowledge of how they're used and how they operate.

LEMON: So, Jim, wrap this up for us, if you will. Because, you know, nine minutes straight we learned from there, we learned that it was 47 guns, and we also learned about this bump stock as well. What do you think?

MAXWELL: Well, I can tell you right now kudos to the Los Angeles -- the Las Vegas Police Department. They had their act together. They made the dynamic decision to go up to that room and end it. If they waited five minutes, ten more minutes, how many more people would have died?

They -- I can't say enough good things. It shows good training, good leadership, and they did what they're supposed to do in an active shooter scenario. This is a textbook response and they did it correctly and I think in the final analysis they saved a lot of lives.

LEMON: Jim, Sam, Chris, thank you, gentlemen, I appreciate it.

We're learning much more tonight about the people who lost their lives in Sunday's massacre. Thirty-four-year-old Tara Roe was an educational assistant and a model. She was at the concert with her husband but they got separated in the commotion. Her sister is now taking care of their two young children.

Off-duty Las Vegas Police Officer Charleston Hartfield is described as everything good about America by his National Guard commander. Hartfield was a dedicated youth football coach.

Co-workers say that they are grateful for the time they had with Dorene Anderson. She had come all the way from Alaska to see the show. And 25-year-old Jordan McIldoon. McIldoon died holding the hand of a stranger at a concert.

I talked to the stranger Heather Gooze last night.

(BEGIN VIDEO CLIP)

HEATHER GOOZE, LAS VEGAS SHOOTING SURVIVOR: I'm not the one that was running in there when we thought the gunman was still on the grounds getting people out of there. All he did was sit with somebody so that he wasn't alone. I would have hoped somebody would have done with that with me.

(END VIDEO CLIP)

LEMON: Heather Gooze stayed with Jordan for hours. She called his girlfriend and his mother to break the horrible news.

[22:55:00] (COMMERCIAL BREAK)

LEMON: Hospitals in Las Vegas treating hundreds of victims of the deadliest massacre in modern U.S. history.

Joining me now is Dr. Clarence Dunagan, the chairman of the emergency department at Mountain View Medical Center. And Colonel Brandon Snook, a trauma surgeon and director of the SMART program at the University Medical Center. We're so glad to have you both here and really people here are very lucky to have you both.

I want to start with you Dr. Dunagan, because you were treating victims as they were coming in the hospital on Sunday night and you say the injuries that you saw were similar to what you saw serving in Iraq and Afghanistan. Explain that.

CLARENCE DUNAGAN, CHAIRMAN OF E.R. DEPARTMENT, MOUNTAIN VIEW MEDICAL CENTER: Yes, sir. I'd say unfortunately was even worse. You know, when you're deployed, our soldiers have, you know, have armor protection on their thoraxes and the poor people that were shot the other night didn't have any of those protections. So I saw worse injuries.

LEMON: And you got called in as many people...

(CROSSTALK)

DUNAGAN: I got called in. Yes. Our group we have about 100 E.R. docs here in Vegas. They sent out a mass text at 11 o'clock saying we needed help. About 20 of us docs and their respective chiefs went in. I initially went to my hospital to Mountain View because they were expecting patients there. When I got there it was empty so I diverted and went to Sunrise and got there about midnight.

LEMON: Listen, this is what you do but nothing to this extent where you...

(CROSSTALK)

DUNAGAN: Nothing.

LEMON: The reaction that you got there.

DUNAGAN: I mean, this is what we train for so we're all adrenalin junkies and, you know, enjoy the procedure aspect of taking care of sick people and taking of critical people and trying to save them. But the enormity of just, you know, Sunrise saw 214 patients.

LEMON: My goodness.

DUNAGAN: So when I got there at midnight, there was 230 patients in a place that usually has 60 patients. LEMON: Yes.

DUNAGAN: So just incredible volume.

LEMON: Colonel Snook, you created a program, this program is called SMART. It places those who serve in the military into rotations at hospitals to help keep their skills sharp. So you were at the hospital on your normal rotation, I understand, and jumped into action when these victims started coming in. How prepared were you and your colleagues for what was happening that night?

BRANDON SNOOK, DIRECTOR OF SMART PROGRAM, UNIVERSITY MEDICAL CENTER: I think we were actually fairly well prepared but at the same time this situation was just something that you really can't predict. I would say that I was actually had just gotten home, I was actually the secondary trauma surgeon on-call so I had just gotten home that evening probably about 9.15 or so and kind of got the call to come back in because we had multiple patients coming in.

LEMON: Yes. And I also understand that your team, you say your team had to call up on certain skills used in war zones on Sunday night. Tell me more about that.

SNOOK: Well, I think kind of like Clarence was saying, unfortunately they was a situation where we saw a lot of injuries that are very closely parallel to what we see in the deployed environment, penetrating trauma, injuries from this situation with gunshot wounds. And that's unfortunately what we see oftentimes when we're deployed, so.

LEMON: Dr. Dunagan, talk to me what survivors who are recovering tonight face. I imagine it's going to be a really long road ahead.

DUNAGAN: Sadly I just got the numbers right before coming on. So, of the 214 patients that Sunrise treated, 59 are still there with 31 in the intensive care unit. So depending on their injuries and Dr. Snook can speak more to the surgical aspect but they will have months and months and, you know, this has change their life forever.

LEMON: You want to talk about that, Dr. Snook?

SNOOK: Yes, I think definitely, you know, a lot of these are extremity injuries. People are, you know, kind of starting to learn how to walk again, some brain injuries, you know, there's a lot of kind of rehabilitation and recuperation from these injuries. These patients are a lot of times going to require multiple surgeries even kind of beyond -- definitely beyond now, so.

LEMON: Dr. Snook, Dr. Dunagan, I know you guys don't like to be called heroes but you are, you definitely are lifesavers. So, thank you so much. We appreciate you both for joining us here on CNN.

This is CNN Tonight. I'm Don Lemon.

We are live right now in Las Vegas.

It is the top of the hour. Our breaking news tonight. Major developments in the worst massacre in modern American history.

[23:00:00] What we're learning tonight is stunning. There's some new photos from inside the shooter, Stephen Paddock's hotel room at the Mandalay Bay right behind me. The photos obtained by the Daily Mail, they show a luxurious room scattered with guns and ammunitions.
