jill snyder of the a.t.f. told cbs' norah o'donnell that paddock had been stockpiling weapons for years. >> reporter: how many firearms were purchased in last year? >> he purchased 33 sphooir arms, the majority of them rifles. >> reporter: that didn't set off a red flag anywhere in the a.t.f.? >> we wouldn't get notified of the purchases of the rifles. we would only get notifie notiff there were a multiple sale which is two or more handguns in an individual purchase. >> reporter: police body cam shows the firepower the officers faced and how they tried to help civilians. >> get out of here! there are gunshots coming from over there! >> reporter: the gunfire continued for more than nine minutes. swat stormed paddock's suite on the mandalay bay 32nd floor about an hour after the shooting and found paddock dead of an apparent gunshot wound. paddock was a regular at the gun shop near his moment in mesquite, nevada. he bought five guns here, including a bolt-action rifle,

three days before the shooting, says general manager christopher sullivan. >> over coffee i was having a moment in myself thinking that i may have very well been the last person to shake hands with that man. >> reporter: marilou danley's attorney said last this afternoon she had no idea he was planning the rampage. the thousands of dollars he wider to her in the philippines, she said, was meant for her to buy a home there. danley thought paddock was planning on breaking up with her. anthony. >> mason: john blackstone, thanks. justice and homeland security correspondent jeff pegues continues to work his law enforcement sources and has more now on the investigation. >> reporter: f.b.i. agents could be seen today sifting through the hotel suite stephen paddock used to rain down bullets on the concert crowd. >> go that way! get out of here! there are gunshots coming from over there! >> reporter: law enforcement is still searching for a motive. f.b.i. deputy director andrew

mccabe spoke to cnbc. >> we don't have any immediately accessible thumbprint that would indicate the shooter's ideology or motivation or really what compelled hill to get there. >> reporter: in the last 36 hours, f.b.i. labs began processing electronic devices like cell phones and computers recovered during searches of his properties. >> i think it's the quieter and harder work that we have to do now, in terms of identifying people who may have known him, who may have seen him, who crossed paths with him in the days and weeks leading up to the event, and that's really where we're focused right now. >> reporter: investigators are also focusing on paddock's mental health, and whether something happened in october of 2016 that pushed him to stockpile most of the 47 guns and rifles in his arsenal. also of interest, whether paddock was considering targeting another large concert that took place in las vegas' week life the country music festival. >> every stay down. >> reporter: manny gomez is a former f.b.i. agent. >> this person was looking for

the best target opportunity, and it didn't matter what crowd he was going to fire into. he was looking for the largest impact for this attack. >> reporter: investigators say paddock spent a lot of his time gambling in the days before the attack and more than a dozen currency transaction reports filed with the u.s. treasury department back that up. anthony. >> mason: jeff pegues, thanks, jeff. we are back now at street level, as you can see, across from the festival grounds where the shooting occurred and police are just about to open up this street finally, three days after the shooting. nearly 50 people are still in critical condition tonight. the president met with some of the injured and the doctors and nurses who saved their lives. here's chief white house correspondent major garrett. >> reporter: president trump landed in the shadow of the mandalay bay hotel and then drove near the scene of the massacre in the center of a grieving city he came to

console. >> i have to tell you, it makes you very proud to be an american when you see the job that they've done. >> reporter: at university medical center, the hospital that received 100 victims, the president thanked doctors and nurses. the president also toured the las vegas police command center and hailed the bravery of officers and civilians who faced the terror head on. >> in the depths of horror, we will always find hope in the men and women who risk their lives for ours. >> reporter: on behalf of a nation, the president offered a promise: >> we know that your sorrow feels endless. we stand together to help you carry your pain. you're not alone. we will never leave your side. >> reporter: and he reflected on how america endures. >> in the darkest moments, what shines most brightly is the goodness that thrives in the hearts of our people. >> reporter: and of the shooter, the president said his

wires were screwed up. >> he's a sick, demented man. >> reporter: the president left as he arrived-- with the crime scene never far away. near the end of his remarks, the president said the nation will wrestle with the las vegas tragedy for some time. there is no sign that reckoning will include any reassessment of the president's opposition to new gun-control laws. anthony. >> mason: major garrett. thanks, major. there was no shortage of heroes sunday night at sunrise hospital. it is the closest trauma center to the las vegas strip and got the most patients as the injured streamed in. so did 100 doctor doctors and n, 100 nurses. today, some shared memories of that awful night. >> ambulances were just coming from everywhere. there were pickup trucks with

parties just cutting in front of me, and just trying to come right to the emergency room. >> reporter: sunrise hospital and medical center's administrative director of emergency services, dorita sondereker. e.r. doctor jason katz, and medical director scott scherr, were in the middle of the chaos as the wounded flooded in. >> there was blood everywhere, and honestly, i want to say bodies on stretchers everywhere. >> oh, my god! >> patients kept rolling in and we were just trying to find placement for everybody. >> mason: scott, what did you see? >> all penetrating wounds, whether it was shrapnel or whether it was direct hits. un, the sickest patients were the ones that had direct hits to the torso or the abdomen and gunshot wounds to the head. >> mason: as all these patients are coming in, are you you, in your head, wondering what's happened? >> none of really, truly knew what happened. we didn't know how many people were shot. we didn't know how many assailants and things like that. >> mason: you don't have the time-- you don't have time-- >> we didn't have time, no. >> mason: did you have places

to put anybody. >> we had an influx of over 200 patients. we were already busy. it was a challenge, and i think the most important thing that i felt and saw that night was the calmness throughout the chaos. we knew we had to remain calm, take care of the patients, triage and keep going. at some point it became just space. if there was a hallway space, a patient went there. if there was an empty chair, a patient went there. >> mason: i'm sure you've seen a lot in a hospital. what surprised you, good or bad, about what you saw? >> no matter how many patients we had-- we had 214 patients that night-- and the communication wo you would think would be broken burke the communication was so impressive. >> one thing that surprised me is seeing a lot of these people that were shot and things and families is how well they handled it. and that, to me, is amazing. >> the patients actually said, "he's hurt more than i am. i'm going to go back here and let them have my bed." >> mason: you see this from a completely different side from most people. what do you take away from this? >> how horrific this was and the

evil that's out there. and, number two, the sense of humidity that was shared with our community, with the caregivers that, you know, came in to help. and last night i-- when i got home, i had tears. i had tears of joy, of pride, of our team and our community, and tears of sadness glmed they did an extraordinary job at sunrise on sunday night and monday morning, and all the families i have spoken with are profoundly grateful. rex tillerson made an extraordinary appearance before cameras at the state department today to refute reports that he had disparaged the president and had to be talked out of quitting. margaret brennan has that story. >> he loves this country. he puts americans and america first. he's smart. >> reporter: the press-averse secretary of state declared that he never considered quitting his job but did not deny having

referred to the president as a moron. >> we don't deal with that kind of petty nonsense, and it is intenned to do nothing but divide people. and i'm just not going to be part of this effort to divide this administration. >> reporter: the state department spokesperson later denied it. >> the secretary did not use that type of language to speak about the president of the united states. >> reporter: the president was told tillerson made the remark after this july meeting at the pentagon. days earlier, the president had blown up at tillerson over sharply differing views on the iran nuclear deal. tillerson himself was frustrated. he'd been undermind on other key,including venezuela and a mideast dispute. it also became personal. tillerson, a lifelong boy scout, was dismayed by mr. trump's comments at a boy scout gathering. >> who the hell wants to speak about politics when i'm in front of the boy scouts, right? >> reporter: the president has been personally frustrated by tillerson's reluctance to defend

his equivocation on charlottesville. >> i think there's blame on both sides. >> the president speaks for himself. >> reporter: but the two men spoke by phone today and tillerson's spokesperson said they're all good and despite the president's tweet this weekend telling the secretary of state to stop wasting his time by trying to start talks with north korea, he said today he has total confidence in him. >> i'm very honored by his comments. >> reporter: senator bob corker, who is chairman of the senate foreign relations committee, said today that while some in the administration are trying to undermine tillerson's authority, it's tillerson, along with defense secretary jim mattis and chief of staff john kelly, who are helping to separate the country from chaos. anthony. >> mason: margaret brennan. thank you, margaret. and still ahead on the cbs evening news from las vegas, a call to ban the device that made an arsenal much more deadly. yes. so let me ask you this... how does diabetes affect your heart?

it doesn't, does it? actually, it does. type 2 diabetes can make you twice as likely to die from a cardiovascular event, like a heart attack or stroke. and with heart disease, your risk is even higher. you didn't know that. no. yeah. but, wait, there's good news for adults who have type 2 diabetes and heart disease. jardiance is the only type 2 diabetes pill with a lifesaving cardiovascular benefit. jardiance is proven to both significantly reduce the chance of dying from a cardiovascular event in adults who have type 2 diabetes and heart disease and lower your a1c. jardiance can cause serious side effects including dehydration. this may cause you to feel dizzy, faint, or lightheaded, or weak upon standing. ketoacidosis is a serious side effect that may be fatal. symptoms include nausea, vomiting, stomach pain, tiredness, and trouble breathing. stop taking jardiance and call your doctor right away if you have symptoms of ketoacidosis or an allergic reaction. symptoms of an allergic reaction include rash, swelling, and difficulty breathing or swallowing. do not take jardiance if you are on dialysis or have severe kidney problems. other side effects are sudden kidney problems,

genital yeast infections, increased bad cholesterol, and urinary tract infections, which may be serious. taking jardiance with a sulfonylurea or insulin may cause low blood sugar. tell your doctor about all the medicines you take and if you have any medical conditions. so now that you know all that, what do you think? that it's time to think about jardiance. ask your doctor about jardiance. and get to the heart of what matters. when this guy got a flat tire in the middle of the night, so he got home safe. yeah, my dad says our insurance doesn't have that. what?! you can leave worry behind when liberty stands with you™. liberty mutual insurance. but prevagen helps your brain with an ingredient originally discovered... in jellyfish. in clinical trials, prevagen has been shown to improve short-term memory. prevagen. the name to remember. >> mason: in the wake of the massacre here, democratic

senator dianne feinstein of california is proposing a nationwide ban on devices that turn rifles into rapid-fire machine guns. she's long supported gun control measures with little success. here's don dahler. >> reporter: stephen paddock was able to porhundreds of rounds into the crowd below because of these devices, bump fire stocks, which are legal, but which senator dianne feinstein wants to ban. >> you have to stand up. you have to say, "enough is enough." >> reporter: with some republicans open to a hearing, it may have a chance, but recent efforts after mass shootings like in las vegas have, met fierce opposition. back in 2013, after 20 children and seven adults were massacred by a person with a semiautomatic rifle, senator fine sign proposed a law against those weapons. congress voted it down. in fact, despite an average of one maz shooting of four or more

people each day since sandy hook, there's been no major shift in the nation's gun laws. daniel webster is director of the john hopkins university's center for gun policy and research. people say, "maybe this will be the one that effects change," and yet it doesn't. why? >> i think the gun lobby has been very effective in promoting the overall idea that any regulation is a violation of the second amendment. >> reporter: new jersey shooting range over ross osias is against any restrictions. >> it's not the device. it's the people. and, unfortunately, you can't fix crazy until it happens. >> reporter: even though a recent pew poll shows 68% of americans favor an assault weapons ban, a republican-controlled congress makes that type of ban unlikely. according to the center for responsive politics, last year, republicans received over $54 million in advertising and donations from the n.r.a. democrats? $265.

in advertising alone, organizations that oppose any new gun legislation are outspending gun-control proponents 10 to one. as for those bump fire stocks that congress may ban, retailers are selling out of them. anthony. >> mason: don dahler. and coming up, two weeks after the storm in puerto rico, the death toll more than doubles.
