Reporter anthony, you could just imagine with the triage must have been like, ambulances arriving one after the other, in all more than 500 patients were transferred to local hospitals.

It is really, mental trauma on your body. You never want anything like this to happen. Our cbs news justice and Homeland Security correspondent jeff pegues has been working his Law Enforcement sources and heres what he found out about the gunman. After Stephen Paddock checked into the Mandalay Bay Hotel last thursday, investigators say he spent the next three days gambling in the casino, and he stock piled a cache of 19 weapons, a mixture of handguns and rifles in his hotel room. Two of the guns were on tripods. Police and the fbi are now trying to determine a motive. Were shocked, horrified, completely dumbfounded about this. Eric paddock, the killers brother says he was interdescreud interviewed by investigators for about four hours. The fact that he had those kind of weapons is just where the hell did he get automatic weapons. Anything . Nothing. No religious affiliations, no political affiliation, no, he just hung out. Stephen paddock was an accountant but family members say recently he was a professional gambler who had won large jackpots. He was also a licensed hunter and pilot who had rented, owned and sold multiple properties in four states over the last four decades. Paddocks father was once on the fbis most wanted list. 9 the 1969 notice described Benjamin Hoskins paddock as a bank robber who was psychopathic and considered armed and very dangerous. Until last nights mass shooting, Stephen Paddocks only run in with Law Enforcement was this 2009 parking ticket. It was well planned out. And it took a lot of strategic thinking. Former fbi profiler Mary Ellen Otoole said paddock may have been planning the attack for years. He had a view of the concert. And he probably had gone to other rooms and chose specifically this room. So there was surveillance that likely occurred before this event. A search of paddocks home turned up 18 additional weapons, thousands of rounds of ammunition and explosives. Today isis claimed responsibility for this attack but investigators say so far they have found no link between padock and the terrorist organization. Anthony. Jeff pegues, thanks, jeff. People who had encountered paddock recently are also having a tough time believing he could have committed mass murder. Demarco morgan has that. As soon as i saw the name, it was an instant recognition. Stephen paddock purchased a shot gun from utah gun shop owner Chris Michael back in february. We have code words between us as staff if something doesnt feel right, or doesnt look right, we will do everything we can to actually top the sale. None of the alarms went up from any of the staff. Today Law Enforcement searched paddocks home. Mesquite Police Officer quinn. We havent had any run ins or contact with him in the past. He is a fies guy, i mean he was kind of quirky but a fies guy. Paddocks neighbors describe described him as quiet, unsocial an having an odd sense of humor but not as violent. It is just kind of unbelievable to think somebody who was, you know, in our community, a member of our community could possibly go out and do Something Like that. It just is unbelievable. Reporter paddock was a a licensed hunter and known to freak gun shops near his home here in nevada. He lived here with his girlfriend Mary Lou Danly who was out of the country and at this time law enforce. Believe she was not involved. Glor joining me is francis townsend, a former Homeland Security advise tore president george w. Bush and a cbs news security analyst. Fran, welcome. There were so many scenarios you considered when you served president bush about what might happen in situations like this. Was this one of them . Absolutely. Remember during president bushs term we had the horrific act of shooter like this at virginia tech. Where he, the shooter went in, had a history of Mental Health problems, obtained a gun and shot up and killed students at virginia tech. And i was there with president bush shortly after the shooting when he went to meet with the families of victims. Its just horrific. And the scar that this leaves on a community, even one like las vegas that is used to large crowds and practices for such events cant be understated. Glor talk about the white house response and what goes into it. So the first thing, you hear this all the time, jeff, in any crisis and thats first reports are always wrong. So you you can well imagine people in the white house hearing that this is a white male, retiree, 64 years old, you say this makes no sense. But it turns out thats accurate. We also, you know, the first reports about injuries and deaths, that number has been climbing all morning as you well know. And i suspect it will continue regrettably to increase. And so what you are trying to understand is what were what was the motive for such an act. Was there a motive. Is this something who has a Mental Health problem or was there something driving him that we need to understand. You want to talk to everybody who had access to this guy, particularly in the last 72 hours. Neighbors, people in the hotel, hotel room workers. All of that will begin to paint a picture for you. Right now you can be sure the atf, alcohol, tobacco and fire arms are doing traces on the gun from the point of their manufacturer until they came into the hands of the shooter. How did he get them, what was he doing with automatic weapons like this. Glor so there is the First Response on the scene and then there is also the First Response from washington and from the white house. And we saw the president speak earlier. Thats right. The president in any moment like this, what we expect of the president in those, in that first statement is to unify the country, to comfort, to comfort those who are grieving or injured, to inspire Law Enforcement, to continue, a very tough task. Remember Law Enforcement las vegas has lost at least one colleague, another was injured. And so the president has to be the unifier. And sort of the comforter at that moment. And i think thats the tone that the president struck. Glor we keep hearing about the profile, a typical profile of Something Like this. And this certainly wouldnt seem to fit. What is that profile and what is it from what you heard so far has surprised you the most . I think the age of the shooter. The circumstances as we currently understand of the shooter is quite surprising. You expect this to be someone younger, someone disgunt el gruntled, a loner, someone disa affected it may turn out this is a disaffected loner, just an older person. But it just doesnt make sense. We dont know really very much about this individual. He didnt even seem to be particularly close to his brother and family in florida. All we know is that he spoke to them after Hurricane Irma asking if they had power back. But he doesnt, we dont know, we havent painted the picture of him yet. The fbi did feel compelled earlier at a News Conference that the local police held to announce that so far they see no International Connection to terrorism. And this was after isis tweeted saying that they served as an inspiration or some sort of coordination for the attack and that Stephen Paddock had converted to islam immediately before. Why did the fbi do that . Well, as you say, isis had put out two statements using their news agency, if you will. They had distributed this on a channel called telegram, it is an encrypted application. And on twitter. And because it had begun to circulate, the fbi wanted to be clear that there is no evidence to support that. Look, i think we ought to understand. Isis is on their heels. They are losing territory in both iraq and syria. They are not winning. And so theyre looking for positive publicity. And thats all this was. This is their attempt to turn the attention to themselves. Glor are you surprised the fbi did that at all. No, i think they did absolutely the right thing. Theyre not going to rule anything out. They know they searched his moment home there is this other property up north they will look at. They will take all sorts of evidence out of there. And also the hotel room. Look at his cell phones and computers, if there is any connection, the fbi will identify it. But certainly as of now we see no connection to international terrorism. Glor so the president goes to puerto rico
