Police searched his home about 90 minutes from the seen in mesquite, nevada and thats where we find nbcs katyy beck with late details. Reporter a quiet Retirement Community 80 miles from las vegas, now the former home of a mass murderer. I turned on the news and my wife and i both, i mean, we were in tears. The shock. Neighbors horrified that gunman Stephen Paddock lived among them in this upscale development, built among Desert Mountains and a government course. Thousands of miles east from there, paddocks brother in orlando suffering the same disbelief. A man he thought he knew. It doesnt make any sense that he killed those people. It makes in sense that he did that. Reporter in 2015 paddock moved here, bought a twostory Single Family home. His brother says so he could relax in retirement. He was a multimillionaire. He had multiple million dollars. Okay. I dont know. We didnt talk. But we had business dealings previously. We owned property together. Reporter police searched his home monday for his motive to kill. This is a crazed lunatic full of hate. Reporter removing 18 firearms, thousands of rounds of ammunition and explosives, searching for answers at the house he shared with his girlfriend. Theres just nothing. He was just a guy. Whats unique for us the gunman, the shorter and the person with him, we the Mesquite Police department had not had any contacts with these people in the past. Reporter enjoyed gam blij, was a licensed private pilot and a real estate owner. He kept . Touch with family is said to have recently provided a new walker for huz elderly mother. You feel sad and you feel surprised and shocked. So many emotions. Kind of nervous. This whole thing was disturbing. Reporter leaving a Mourning Community and country to wonder how he could have done this. That was katy beck reporting. And emerging from the chaos, so many incredible stories of survival including one man who said he ran in to help others only to be struck himself by gunfire. Reporter it should have been a night out with friends and some Country Music under the vague as stars. For 28yearold thomas gurnd son, instead it was this. I talked to a couple of other guys. I said i think its fake because we really did. We thought somebody was, you know, just trying to mess with people. Reporter it was a gunman on the 32nd floor of the Mandalay Bay Hotel trying to kill people. I look up and i see flashing lights from what i thought was about the 20th floor perfectly in sequence with the gunshots and i right then knew it wasnt fake. I knew he was shooting from that hotel. And right then and there, he took my leg out. Gurnd son was shot through his right calf. It was very odd. I didnt feel pain really. I went down and immediately just saw blood everywhere. Gurnd son said thats what he was most scared, thinking hed be trapped in the open, bleeding with no one to help. I really felt like i owe myto a couple of girls that ill probably never find out who they are. They grabbed me by the legds, they dragged me over to the side and took her belt off and put a turn ket on my leg. Grabbed a couple of guys next to them and said you will carry him out of here. Reporter but gurnd son was far from the clear. Just to move him and other victims out of the line of far, First Responders got the wounded to the hospitals any way they could. They were literally loading us into the back of toe trucks. I was laying on somebody that i honestly dont believe made it. At University Medical center gurnd son learned the but missed both bone and artery. Unlike many others hes expected to make a full recovery. Nobody cared what you looked like last night. Nobody did. They wanted to save your life. A very lucky man in a city where luck can make all the difference. We turn now to former fbi special agent in charge who joins us over the phone. Rick, we thank you for being with us here this hour. So many questions dlug a motive. Why would this happen, why would he do this . What are those officers and investigators focusing on now . Yeah, so that is the 60,000 question is why. And one of the things that weve learned in looking at these mass casualty active shooter events is there is no one pre file for an active shooter. However, theres typically a pathway to violence and that pathway starts with a grievance and it moves from a grievance to an ideation and that ideation or m. O. A. B. Could be anything from extreme anger to a perception of persecution. The person could have a paranoid ideology. He could have a Mental Health issue, depression, antisocial narcissistic behavior. He may feel that he has to preemptively strike dense an individual or society. In the case of terrorism it can be in ideation the individual typically goes towards a research and planning phase were theyre Online Learning at weapons and learning how to build explosive devices and then they go from aspirational to operational preparing and staging for the actual attack and then the last step in this pathway to violence is the affirmative decision to act and to attack. So the investigators are going to be looking for clues along that pathway. And theyll find that in interviewing his girlfriend, who probably knew him better than anyone else at this point in his life. Theyre look at financials to see if there may have been a trigger, a big gambling loss would be an example where he feels like, you know, las vegas is my problem and thats my grievance and im going to strike against las vegas. And thats a supposition, obviously. And then theyre going to look at the caters of research. And they can find that prepares on a computer hard drive. 64yearold male may not be as computer savvy. So he may have kept a diary. The reports that there was a computer found in his hotel room there at the mandalay bay, so what they find in that, of course, many questions there. But does it strike you at this point when you talk about this pathway of grievance and the red flags that there were none at this point that were seeing now . Well, thats not unusual in this early in the investigation. Okay. When you Start Talking to people it may not be readily parent that he had a grievance and it could be against an individual, a workplace, against society. So but thats usually starting point on this pathway. The person has a defined problem. Right. With somebody or something and then it escalates and theres a triggering event. And typically you see these sort of stages in this pathway occur. And the investigators are going to be looking for that through,up, the forensic also through las vegas has great cc tv. Theyre the most photographed city in the world, right. So theyll be able to put together a really defined timeline of all of his activities from the time he arrived in las vegas until the time the attack ended. And that could offer some clues. Does it stand out to you at all that there was no manifesto so far that we know of thats been reported publicly, no letter, no suicide note especially when you have mad men like this who are wanting the credit for it, who would want their name out there, would want the reason known but so far nothing . Well, again, one of the things about these things is theres no specific one profile. Theyre all sort of individual events. And trying to get into the mind of a mad man is a very difficult thing to do. You know, the fbi whaifbl Analysis Unit has gained fame trying to do that. And, you know, they continue to learn more things, you know, Mental Health issues and Emotional Health issues. But its a myth to think that a person just snaps. This escalates overtime, and theres typically a triggering event. But thats not snapping. This was an organized killer who took some time and it took planning and it took a lot of logistics to move all of those weapons and ammunition up to that hotel room. It took some surveillance to discern his target frlt it didnt take a lot of sophistication. It was sort of a pray and spray. He didnt have to have marngs man ship or weapons training. So it will be interesting to see what the investigators find. But again, be patient. Were very early on in this investigation, you know. Usually around 72 hours is when the investigators have a pretty good handle on things, and they may be very cautious because this is an internationally significant event. Theyre going to be very kausht and make sure they are get it right before they put the public face forward and bref the media and the American Public on what theyve found. What the world is waiting for are those answers to every to why and that motive. Former best of my memory ham fbi special agent. Thank you for your time and perspective. Thank you. Our special live coverage of the mass shooting in las vegas continues right after a quick break here on thoughts j prayers need to be matched by action. Our job is not to just send good thoughts. Thoughts and prayers are not enough when more moms and dads will bury their children this week and theyre not enough when sons and daughters will be forced to grow up without their parents. We must act so that we doinate become numb to this preventible carnage. This is not preordained, it is preventible. Now the shock of yet another mass shooting reverberates in washington. The debate is raging once again. Some saying the immediate aftermath is a tragedy is no time for the debate, while others say it is precisely the appropriate time. Hally jackson has those details. For President Trump somber silence after a sobering speech. It was an act of pure evil. In moments of tragedy and horror america comes together as one. Reporter the president respond thug tack with remark that called for unity but not gun control. As the compattive debate resufferesses. It would be premature to discuss policy when we dont fully know all the facts or what took place last night. Reporter gun control advocates see it differently. If we dont act now reporter at the capitol, former congresswoman shot in the head in arizona in 2011 delivered a message to her former colleagues. The nations counting on you. Reporter by now its a familiar pattern that not even the murders of 20 children at sandy hook could break. A devastating shooting, a national gun dialogue grid locked with disagreements over tougher background checks and Mental Health regulations. You cant sit here and call for ban this, ban that when you dont even know what was used. Reporter rallying around the second amendment. With the gop in control of congress and the white house, it looks like little will change. I want to bring in clarence cox, the president at the National President of noble or the organization of black Law Enforcement executives. Tack to us about this mass shooting and the impact it could have on Law Enforcement. Certainly its a tragedy and i cant underline that enough. The impact is we do all kinds of things to prevent what happened october 1st. And this guy was one televise those people who was not on the radar because he didnt have the regular indicators or some of the things we look for in Law Enforcement. And much like rick said, the former fbi agent you just had on, this is just one of the things thats baffling. The profile is in the fbi behavioral studies group. Its unfortunate that 16 months ago we were doing the same thing. So this is just one of the things where were frustrated at Law Enforcement to have to continue to see this and to hear people keep talking about uniting the country behind this. First of all we shouldnt be divided and secondly, they shouldnt be politicized. And the action is what so many people are wanting to see. And talking about that and your frustration. In a statement he called on the community to be more involved in reporting suspicious people who show indicatorprise possible violent acts. But you have this madman here, no criminal record. His brother and close family describing it as an asteroid falling for thum sky. No manifesto. No letter at this point. But so specifically and strategically planned as far as the actions there. The 23 weapons having a joining room where he could shoot at. What would the red flags have been . Is it too early to know anything at this point . Sglits rr kind of early to have a large cachet of weapons would not be an indicator because theres so many gun enthuse i shoulds out there, you cant pin it on that. Again the no criminal record and you would think there would be weve seen so many times an affiliation. There was no political or religious affiliation here, nothing to point to any kind of motive. Youre right and being 64 years oerlksd i agree with the assessment as it relates to the computer. Very few people not leave a trail and i would be interested to find what they get off the computer in the room there. But agon because of so many different avenues of terrorism, were busy tracking those people who put out those strong indicators. So someone like this is struggling. As we think about it the results of someone who was able to fly. How does thart change the way you and noble go about it . And knowing thatd you cant so much on those indicators but in this case there were very little. Its kind of one of those things where you continually say if you see something, Say Something. So many of our citizens are afraid to Say Something because the retribution, sometimes, after youve reported something that may turn out not to have been anything. So weve got to continue to edgedate our country and encourage them and give them things that woept put them in a position where their identity is give up. And weve got to insure confidentiality. Weve got to insure the safety of those people who give up information like this and youre critical to successful investigations. This troubles me. Ive shot the about this since it happened. Well, how tough do you think that will be, especially with his girlfriend . Before we knew this gunmans naim, we were puttling the photo of the girlfriend up with license plates with her photo and of course sheesz rr out thfr country. So far police have cleared here. Im sure theyre going to question her. And how valuable her information will be to shed light on this. This is significantly impactful for her life going forward. Theyre going to blame her for this accident. And weve got to work on a better filtration of information because you sometimes get it before we do. Fortunately you have talented in the media who are great investigators when it relates to things like this. But weve got to contain this information somehow, whether shes involved or not. And you think about a tluft victims identified in this tragic event. Theyre going to be suffering from post Traumatic Stress disorder after this has been years from now, soft of like the other people in orlando and sandy hook and weve got to start compounding this information and right now this is an ongoing investigation. Butted many of the import nlt sights have been revealed and theres no surprise. The national orlginization of black Law Enforcement 2w0ibs. Well be right back the latest on where things stand into the investigation of a man who carried out the deadliest mass shootding in modern day america.

To try to gain more insight n to all of this, were joined by crim naulsh in san frind doetd pope oosbz wr sffrmation spat skav udstrieing trying to process. The first many have is why . Your thoughts on what were arer learning and what motivated them. Great question. The first thing that was tabled was when the mock news Agency Claimed responsibilitresponsibi. They seemed to be claiming credit for almost every drain railment. A casino attack in the fill pones. So we can table that. One of the things he we often see is people whoop relationship there hell talk to people one of the things that we need when we create a tempilate for motivations. They can be political, religious or a hybrid. And four, psychologically danger. Or theyre a socio path. They know what they do is wrong and do it anyway. Frrsh this ktd be anothericer as well monopoly that well see in the dis to come. Possibly and again this is pure speculation. And perhaps benefit or revenge. Let me say one quick thing. One thing when people scapegoat and we saw this from southern california. You have the beauty supalestine shes at. The violence, wens it goeszsose it eseb when you have somebody with that ability of being psychologically dangerous, the other investigators weve spoke to say its not just one thing to trigger this. How much this was planned out that he was there for three days. He the arsenal of weapons. Doyou believe it ktd have been a c comati comation. And my brother owed me enough money. Perhaps this is something that was patszed on gemetically to the. What i thing is so interesting is that we saw this so there are peep whom can have severe wental illness, spaelsh splarly if youre kupt comfortable. Wouldnt a madman, somebody capable of doing somethingo. N. Hoar a letter indicates he was the norway shooter. Couldnt describe whether ernot he was categorically mentally ill or not. So sometimes the manifesto is the violence itself. We live in a stooet where pailance is now a frame of exprevs. And thats the unfortunate poort in here. This man will be known for the first mass shooting in american history. Thank you so nouch. This really does bring out the best in people. And those are the stories we hope to continue. Frr frrsz.
