The las vegas sheriff says he is confident danley will provide some answers. Body cam video released yesterday shows Stephen Paddocks rapid gunfire pinning down officers as they helped people get to safety. This morning we know the names of nearly all of the 58 people who were killed by the gunman. They come from across the United States and canada. Norah odonnell is near the shooting scene outside the mandalay bay resort and casino. Norah, good morning. Good morning to you. You know, in the last 24 hours we visited a hospital and heard remarkable new stories of survival. Weve also talked to police and the bureau of alcohol, tobacco, firearms and explosives. And this morning we know important new details about how and where Stephen Paddock got his weapons. We know he bought 47 guns legally and the atf tells us he purchased 33 firearms in the last year alone and a majority of them are rifles. Some of them were highend models with custom made features, like scopes. The atf tells cbs news that none of the purchases set off any red flags. Were also getting our first look inside the hotel suite where paddock orchestrated his massacre. While his motive remains a mystery, its clear he was armed for an even longer siege. This Police Body Cam video shows the relentless firepower. First responders were up against sunday night. For up to 11 minutes, Stephen Paddock shot concert goers with seemingly endless bursts of gunfire. Over a dozen volleys in all. He had been stockpiling his firearms since 1982. According to jill snyder, a special agent in charge at the bureau of alcohol, tobacco and firearms. How many firearms were purchased in the last year . From october 2016 to september 28th, 2017, he purchased 33 firearms. The majority of them rifles. That didnt set off a red flag anywhere in the atf . We wouldnt get notified of the purchases of the rifles. We only get notified if there was a multiple sale, which would be two or more handguns in an individual purchase. Why is there no notification if someone is buying multiple rifles . Theres no federal law requiring that. Snyder revealed to us that paddock rigged 12 semiautomatic rifles with bump fire stocks. The devices allowed the guns to fire continuously, much like an automatic weapon. A semiautomatic rifle with a bump fire stock on it is not an illegal machine gun. How big were the ammo clips . The ammo clip capacities ranged from 60 rounds to 100 rounds. So he had huge clips of ammunition . Yes. Cbs news has learned paddock also set up cameras in and around the luxury suite he turned into a snipers nest, a kind of Early Warning system for any approaching police officers. As he fired out of two windows, one camera peered out the suites peep hole. Two more cameras were in the hallway outside. One of them was on a room service cart outside the door, says Las Vegas Metro pd sheriff, joe lombardo. Was the gunman recording . Was the gunman transmitting that video anywhere else . Im not aware of any transmission, but there was cameras. And he had set up how many cameras . I dont know what the specific for what purpose, do you think . I anticipate he was looking for anybody coming to take him into custody. So essentially you have a recording of him carrying out this carnage . No. Thats not essentially what im saying. That is being evaluated. The fbi took all digital and electronic evidence into custody and we are evaluating it. So the fbi has a lot to still go through in terms of that video, but also bottom line anyone can buy multiple semiautomatic rifles at any time. The atf tells us they wouldnt know about it. Jill snyder of the atf also told us that they have agents looking into whether paddock was spending time at an area gun range around the las vegas area. Fbi agents met paddocks girlfriend at Los Angeles International airport last night and cbs news confirmed that Marilou Danley was on Philippine Airline flight 102, seen here arriving at lax. Video from local station knbc shows officers apparently escorting her through the wheel po airport in a wheelchair. Jeff pegues is in washington and has been tracking it. Reporter good morning. Marilou danley returned to the u. S. After three weeks overseas. She lived with the gunman, was around him as he was building up that arsenal. Investigators will move to quickly get her in a room for an interview, and Law Enforcement sources say that could happen as early as today. Marilou danleys sister told australias 7 news that her sister might be the only one who can put the puzzle together. They believe Stephen Paddock sent her away so she wouldnt interfere with his plans. He sent her away. She didnt even know that shes going to the philippines until steve said, oh, marilou, i found you a ticket to the philippines. Reporter investigators believe danley can answer many lingering questions about paddocks motive and how he was able to stockpile so many weapons. Danley who is 62, is an Australian Citizen but native of the phillipines. She met Stephen Paddock after separating from her exhusband in 2013. He loved her. Reporter eric paddock, stevens brother, said the couple met while marilou was a hostess at a coasino in reno. They had been living together for years in reno and most recently at this house in mesqui mesquite, nevada. As he was descending into hell, he wanted to take care of her. Reporter while danley was in the philippines, paddock transferred tens of thousands of dollars overseas. Eric believes his brother did it to protect her. He manipulated her to be completely as far away from this and safe when he did this. Reporter it is unclear where danley will be interviewed. Law enforcement sources say she is not under arrest. Norah. Jeff, thank you so much. We are hearing more stories of bravery and hope after the massacre. Michael caster is one of the wounded. He said he owes his life to his girlfriend, who made sure he was carried to a strangers car and then taken quickly to a hospital. Adriana diaz spoke with him last night and shes outside Sunrise Hospital in las vegas. Adriana, good morning. Reporter good morning. The sense of grief is still so strong here, but so is a sense of gratitude. We spoke to michael caster and his girlfriend in his hospital room. Theyre both still coming to grips with what happened sunday night. I was on the ground, i could not move. I had no feeling from the torso down. Reporter shortly after this photo was taken, 41yearold michael caster was shot through his lung. The bullet hitting his spine, just missing his heart. His girlfriend, tawny, found a table to use as a gurney and others helped her carry him to a strangers car. People were telling me just leave, and im like im not leaving him. By the time i got to the hospital, my lungs were already full. With blood . Yeah. Reporter caster is one of hundreds of shooting victims who survived sundays rampage. 27yearold tina frost is in a coma and currently on a respirator. Mary is tinas mother. The bullet went through h her. She leaves behind four children. Chris, her 13yearold, loved seeing his mom at his football games. Im not going to be able to hear her in the crowd again. That was my last memory of her cheering me on. Steven berger had come from minnesota to celebrate his 44th birthday. Hair dresser Stacee Etcheber was a mother of two and Heather Alvarado ran a day care center. Michael caster said he too might have died if his girlfriend hadnt got him to the hospital so quickly. Mike, if tawny wasnt there i took a bullet for her, so she was just paying me back. No, i dont know. Reporter part of casters lung was removed and he faces a long road to recovery, but he says doctors told him with time and physical therapy, he will be able to walk again. He and his family are looking for any alternative or experimental treatments that could help. Norah. Wow, thank you. Its so difficult to hear about all of the victims. President trump and the first lady are on their way to las vegas right now, and before they left washington, mr. Trump called the shooting a very sad thing and said police have done aanstic job. Major garrett is here ahead of the president s arrival in just a little over two hours. Major, good morning. Reporter good morning, norah, when President Trump touches down here, he will do what every american president does in these situations, console those most deeply affected by this mass shooting, including survivors and First Responders. Sadly, such events are by no means new to the american presidency, but mr. Trumps unapologetic support for the National Rifle association during the campaign and now during his presidency could invite new scrutiny. Yesterday the president called the shooter, Stephen Paddock, quote, sick and demented and the white house said now is simply not the time to talk about gun control or efforts the president has already taken to erase some n control moves put forward by president obama. Now, there is little evidence any of the long proposed gun control laws would have prevented the mass shooting here. The question for mr. Trump and lawmakers on capitol hill is whether preventing all Mass Shootings is the only acceptable standard or would using new federal laws to reduce their frequency be an acceptable alternative. And thats the question. Major, thank you so much. Lets go back now to bianna in new york. Norah, thank you. Well, the Las Vegas Massacre was the latest in a long list of Mass Shootings in the United States. By one count, there have been more than 1,000 since the sandy hook killings in 2012. An estimated 93 people are killed by guns every day in this country. And now democrats are trying to restart the debate over gun safety. Nancy cordes is on capitol hill with why new laws may be difficult to pass. Nancy, good morning. Reporter good morning. Those democrats felt a surge of hope on tuesday when the president said that he would be speaking about gun laws as time goes by. Theyre pushing in particular for restrictions on the kind of equipment that the shooter apparently used to make his weapons even more lethal. At some point enough is enough. Reporter calling the Vegas Shooting a day of reckoning, democrats urged the gop to pick a policy, any policy. Is there nothing that we can do . Reporter among the options they say are bills to mandate background checks, prevent stalkers from buying guns, and ban socalled bump stocks. Which the vegas shooter may have used to increase the rate of fire on his semiautomatic weapons. The only purpose to have one of these devices is to see how quickly you can kill a lot of people. Reporter some republicans say theyd consider it. Thats something i think that well take a look at. Reporter but others said this isnt the time to talk policy. I dont think we should politicize it. Reporter senator leader Mitch Mcconnell was one of them. I think its premature to be discussing legislative solutions, if there are any. Reporter House Speaker paul ryan argued guns are not the main problem. What can you say to americans who just want to know how the body you lead can make them more safe in the face of shootings that seem to be getting more frequent and more deadly . One of the things weve learned from these shootings is that often underneath this is a diagnosis of Mental Illness. And thats why the house of representatives passed Landmark Mental Health reform just a year ago. So then was it a mistake to make it easier for mentally ill people to get a gun . Reporter ryan later said congress rolled back that obamaera rule blocking purchases by people with Mental Illness because it infringed on the rights of legal gun owners. He did say the house has no imminent plans to vote on a bill to allow the sale of gun sigh lensers. That bill is not scheduled now. I dont know when its going to be scheduled. Until recently that appeared to be on the fast track. The National Rifle association invested heavily in candidates in 2016, including the president , spending 52 million, almost triple what it spent in 2012, charlie. The death toll in puerto rico climbed to 34 people in the wake of hurricane maria. 93 of the island is still without power. President trump visited the battered u. S. Territory yesterday to meet with storm victims and First Responders. David begnaud is in san juan, puerto rico. David, good morning. Reporter good morning. One of the officials that the president met while he was here was the mayor of san juan who has been one of the fiercest critics of his administrations response to the hurricane. But after meeting the president , the mayor met with the white house staff, and when she walked out of that meeting, she tweeted that the white house staff seemed to really understand the disconnect between, as she put it, what is supposed to happen and what is happening here. Theres a lot of love in this room. Reporter President Trump and the first lady were greeted by a friendly audience in the town of guaynabo. The president handed out supplies, tossing paper towels into the crowd. Mr. Trump also toured the neighborhood and met with people whose homes were damaged by maria. Were going to help you out. Have a good time. Thank you. Thank you, mr. President. Its great to see you. Reporter the president and first lady got a look at the destruction by helicopter. They did not visit the harderhit areas of the island where there is no Running Water or power, forcing people to drink and bathe with stream water. During a briefing earlier in the day, President Trump praised the federal governments response, but seemed to downplay the devastation of maria compared to that of hurricane katrina. If you look at a real catastrophe like katrina and you look at the tremendous, hundreds and hundreds and hundreds of people that died, you can be very proud of all of your people, all of our people working together. Reporter mr. Trump also appeared to criticize the u. S. Territory for their more than 70 billion debt. I hate to tell you, puerto rico, but youve thrown our budget a little out of whack, because weve spent a lot of money on puerto rico. Reporter later, the president seemed to suggest puerto ricos debts may be forgiven. We have to look at their whole debt structure. You know, they owe a lot of money to your friends on wall street and were going to have to wipe that out. Reporter not long after President Trump left the island, the governor of puerto rico announced the death toll has risen from 16 to 34. The majority of deaths were told were due to flooding, mudslides and flying debris. But, gayle, were also told people died from heart attacks, suicide, and a lack of oxygen. The more you hear, the sadder it is. Thank you very much, david begnaud, reporting from puerto rico today. We have an update on one las Vegas Shooting victim that we told you about yesterday. Her name is kristin babik, shes a law student, and she tells norah about the people who helped her survive and why it helps her focus on her future. First, its 19 minutes after the hour. That means its time to check your local weather. A person wrongly identified online as the las vegas gunm
