[Lemon:] Don Lemon here live in Las Vegas the scene of the worst massacre in modern American history. The killer Stephen Paddock killing at least 59 people, wounding 527 with a hail of bullets from his hotel room at the Mandalay Bay right behind me. CNN's Tom Foreman has more on why the attack killed so many people Tom.
[Tom Foreman, Cnn Correspondent:] Don all you have to do is look at the map to understand why this attack was so deadly. There is Las Vegas strip running through the middle of things this area where the festival was is right over here. And the window from which this man was shooting at the Mandalay Bay, you can see right up in here. From this vantage point he really had an over arching view of the entire area of this concert. Yes, it was about 400 yards away, but he was able to take advantage of certain things that made this extremely dangerous. For example, instead of trying to place shots, it seemed as if he was simply sweeping the ground with this very rapid fire. With people packed densely together like this, that was a way that he could hit an awful lot of people even if he wasn't aiming that well. Secondly, there were exits here from which people could leave, but many eyewitnesses say people tried to head back out toward the boulevard because that's where they came in along those gates, you can see on the left there. That led them actually closer to the gunman, not further away. And lastly, a lot of people because they didn't know where the gunfire was coming from, simply hunkered down in the middle of that space trying to tend to the wounded, and that left them completely under the guns of this man up here. And he was prepared for the attack. Authorities say when they finally managed to get into the room where he was already dead, having killed himself they believe, he had thousands of rounds of ammunition between there and his home. They say that he had 35 guns total 17 at the hotel that he apparently brought in, in ten suitcases over a period of days. He had scopes for some of the rifles. He also had a hammer that he used to smash out two of the windows. And in his car he had ammonium nitrate which could have been used to fashion a bomb if that's what he had in mind. Bottom line, a lot of preparation for an attack here and that's another reason it was so deadly Don.
[Lemon:] Thank you Tom. Appreciate that. And the number of guns now up to 42 a little bit more than when Tom taped that for us just before the show. Now I want to bring in Cory Anne Langdon. She is a Las Vegas cab driver who helped panicked concert goers escape in her taxi. Let's watch some of it.
[Unidentified Male:] Broken leg. Broken leg. Drive. Drive. Broken leg.
[Unidentified Female:] All right. Ok. Ok.
[Unidentified Male:] Broken leg. Broken leg.
[Unidentified Female:] Please. Ok. What happened?
[Unidentified Male:] Let's go. Is there somebody out there? All right. Gun. That's what happened.
[Unidentified Female:] All right. Go. Go. OK. All right. Oh, God, there is an active shooter. OK. Are you kidding me? No. Go. Go. Go.
[Don Lemon, Cnn Anchor:] Unbelievable. She's telling you so many people are dead. You didn't know, right?
[Corianne Langdon, Cab Driver:] No, I didn't know. I had it was unbelievable to me.
[Lemon:] Where were you when the gunfire started?
[Langdon:] I was actually staging at the Mandalay Bay in my taxi cab and it was very quiet. And we first I first heard a couple of pops and I just thought it was fireworks or firecrackers coming from across the street at the venue, the harvest festival venue. And after a while, then you started hearing a lot more and that's when I decided to turn my video camera on and my cell phone. And then it just continued to keep going and going and going. And but nobody was doing anything at the Mandalay Bay. Everybody was just kind of standing there. The taxis in front of me, were they weren't doing much of anything. And they you know, nobody was doing anything. I decided to get out and go check it out and the doorman wasn't doing anything. And then my fellow taxi drivers, on our dispatch radio, started saying, hey, they're shooting at the Mandalay Bay. Everybody get out of there. And I looked at the Mandalay Bay and I looked at the Bally and there wasn't anything going on. Everybody was just kind of walking around, doing whatever.
[Lemon:] It was happening above you.
[Langdon:] Yes, it was. And I could tell that it sounded like automatic gunfire. I don't know that much about guns but it sounded weird. And so I got out of line and I went around and I came back around and I looked up. And I could see the gunfire and the shots. Again, I don't know much it just looked like the lights going off. Yes, I guess.
[Lemon:] So then when you came around, and where did you pick up people between the hotel and
[Langdon:] No, actually, no. I got out of there and I came back down and I went around across Las Vegas Boulevard, over by where the entrance and exit of the harvest festival was. I knew something was going on because then that's when I saw all the cops there. I drove by and there were cop cars and cops on the ground with their rifles and everything. And as I came around, all these people some people were just walking, though. It was crazy. And then I looked over and there was people climbing over the fence and people started screaming and running. And then two people came up to my car and said, "She's got a broken leg," and I said, "OK, get in." And I don't know, me being the consummate taxi driver I turned on the meter and said, OK, where are we going? And we they said "Go, go, go. Just go, go. There's an active shooter. There's people dead everywhere." And then suddenly all these other people started trying to get into my cab and I think I had at least like five or six people in my car. And so I said, OK, nobody else, nobody else. There were still people trying to get in. I feel so bad. There was one guy in front of my cab, he was going, please, please and I didn't want to I couldn't take anybody else.
[Lemon:] Where did you take them all?
[Langdon:] I took them they wanted to go back to the Luxor, New York New York and, I said, no, I'm not going to take you that way. I'm going to take you away from the Strip. And they were screaming. They said they were covered in blood and they said that there was people laying on the ground dead and the active shooter and, you know, and the lady behind me, one of the ladies said, oh, my God, the guy behind me was shot dead and it was just so surreal. It was like the "Twilight Zone" for me. I was in denial that this could actually be happening in my town, my beautiful city.
[Lemon:] People think taxi drivers, you see everything. Especially nothing every you put six years you've been out here.
[Langdon:] Yes. Six and a half, yes.
[Lemon:] Nothing like this.
[Langdon:] No, nothing like this. And I feel so bad for the families and the victims and it's just so sad. And so awful. And I you know, the heroes are the people that the first responders and the cops and the EMTs and ambulance drivers and then the doctors and nurses at the hospital, and then the people that were on the ground, covering their loved ones.
[Lemon:] You said you're not a hero.
[Langdon:] No.
[Lemon:] You told me off air don't call you a hero.
[Langdon:] No.
[Lemon:] Because the first responders are the heroes.
[Langdon:] Yes, yes, definitely, yes. I just happened to be in the right place at the right time and I had a video camera with me and I think that's why I'm here, so...
[Lemon:] How do people get through this? How do you get in a crowd and feel safe ever again?
[Langdon:] You know, I guess I'm just I'm not going to let the terrorists win. I'm not going to be afraid and I don't think that we should be afraid, because then they do win. I'm going to go on with my life. I have a story to tell now and I think we need to grieve and feel terrible but still live our lives and don't live in fear and don't be afraid to go to a concert. You know, they have this wonderful concert here every year and it's just a tragedy what happened. But go out and live your life. Thank you.
[Lemon:] Thank you. Appreciate it.
[Langdon:] Sure.
[Lemon:] Did a good thing. Thank you so much. At least 59 people lost their lives and last night here in Las Vegas in this shooting. We're learning more about them tonight.
