Of those inside the can club. Right now fewer than half of the names that have been killed have been released by authorities. Still a lot of families desperate for information. We got clarity from officials about those three hours between 2 00 am when the shots first start ringing out to 5 00 am when officials went into the club and took the shooter out. Before that 5 00 am entrance into the club they previously had attempted to go inside. They exchanged shots with the shooter. And he retreated into a bathroom. They paused, because he mentioned some kind of explosive device. Youll remember all day yesterday, atf officials were on the scene, scanning for potential explosives. He had something that resembled a device on him, is what officials told us. That kind of gave them pause. Closer to 5 00 am, we were out here on the scene and heard a huge explosion. It turned out to be a distractionry device set off by officials in order to distract the shooter. And thats when they went in, with an Armored Vehicle into a bathroom where he was hiding. Officials gave us a taste of the way they described it. Here is that sound. We used our Armored Vehicle, bearcat Armored Vehicle to punch a hole in that wall, defeat the wall. Theres a hole in the wall about two feet off the ground and about two, three feet wide. We were able to rescue dozens and dozens of people that came out of that hole. The suspect came out of that hole himself, armed with a handgun and a long gun, engaged in a gun battle with officers where he was ultimately killed. So, obviously, theres still a lot of families awaiting details to find out what they fear most, that their loved ones may be gone. We also heard from officials that this is an extremely diverse place. Orlando is home to a huge puerto rican population. 20 of 24 people identified so far are latino. When we get the full list of those that were inside the club that were killed, we expect there will be a lot of latinos on it as well. Erin . Thank you so much, boris. New information is just coming in. This is a developing story. Lets get to evan perez. What do you know right now . Erin, were learning what investigators have learned, that in recent weeks the shooter, mateen, attempted to buy militarygrade body armor, body armor thats even higher level than what ordinary Police Departments supply to their officers, the of body armor that would allow him to survive prolonged shootout with Police Officers. This indicates to investigators a couple of things, including that perhaps he has been planning this attack for weeks, perhaps much longer than that. This wasnt something he woke up saturday morning and decided he wanted to carry out this attack on this gay nightclub in orlando. It also indicates that he had no intention to commit suicide. This is something he wanted to do and prolong this gunfight with Police Officers. Erin . Evan, its pretty stunning here. Obviously, a big part of the question about all of this has been how long he planned t as youre reporting now, this means at least it was weeks. The family saying it was just perhaps it does but maybe not. They were saying in the past week or so, two gay men were kissing. They say thats what may have set him off. Youre saying this particular plan could have gone back before tha that. Exactly. Thats what investigators are look at. The store where he went to buy the body armor declined to sell it to him. Its unclear why. He had the license and was capable of buying the two weapons found at the scene. Its unclear why he was denied this purchase for level three body armor. It goes back to the statements made by the family, which is that he saw two men kissing in miami in bayside, miami, and that is what drove him to do this. It certainly, perhaps, adds more information f investigators to look at. Erin . Thank you very much, evan. I want to get to carol now. Carol . Thank you very much. Over my shoulder, you can see Police Activity there. Thats the nightclub, pulse. Investigators are on the scene, trying to putt piece together what happened. The crime scene well, lets just say it is very difficult. Investigators are trying to figure out exactly why this gunman ran on the shooting rampage at this particular club. Now painting a chilling picture of a man with two very different personalities. People who lived nearby the shooter say he was a quiet man. Shooters exwife say he was abusive and unstable. The shooters father said he didnt see any warning signs. Liste listen. He was a very respectful person. He was respected by his family, immediate family, especially, the parent. He was on time on his work. He never slack off his work. He was on time. We provided really a lot of love and care for him. He was well behaved. Appearance was perfect. I didnt see any sign of worrying, being upset or nervou nervous. Lets bring in cnns palo sa sandoval. Reporter so many investigative leads have led investigators here to florida, twohour drive south of orlando. People living in the actual complex where the gunman lived are still in a state of disbelief, the complex you see over my left shoulder. Parking lots that are typically used for the residents empty right now. This morning is the first time it was actually opened by authorities. Scene essentially released by authorities. Were beginning to see people return home slowly, but steadily. They are still in a state of disbelief. One gentleman coming home for the first time the last 24 hours explained, really, the extent very limited extent of his interaction with the gunman. Take a listen. Very quiet. Kept to himself. Normally everybody says good morning. Never said anything. Kept to himself. He looked like the normal joe. He wasnt, obviously. You never know who your neighbor is, bottom line. Again, we are here in ft. Pierce, florida, place where the gunman lived, place where he worked. According to my conversation with one of the local spiritual leaders, worshipped as recent as friday. Something fairly significant here. There was a car parked a couple of parking spots to where were standing right now. Looking in the window, youre actually able to make out what appears to be federal search warrant with the gunmans name on there. Were trying to figure out what exactly could be behind that. As you look through that search warrant youll find crucial evidence was collected here just yesterday from the interior of that car, including dna samples, vacuum samples. While that is fairly standard of any federal investigation, this is significant as just this morning we heard from federal prosecutors in orlando saying they are looking into the possibility that there could have been other individuals involved in at least the planning process. This is a clear indication that investigators are trying to look at all avenues here, including a vehicle that remains, really, considered evidence at this point. Especially what was removed from inside that car, carol. The main headline of the People Living in this quiet community, they still cant believe a man that they lived so close to is responsible for so much pain. Carol . We hear that same story so often. Polo sandoval, thank you. As the gunman moved inside the nightclub, those trapped inside hid wherever they could, bathrooms, dressing rooms, even underneath the bar or under the bodies of other shooting victims. Many inside the club used their phones to call for help. Nina justice got several texts from her son, eddie, just after 2 00 am. This is what the texts read. Quote, mommy, i love you. In the club. Theyre shooting. Trapped in the bathroom. Call police. Im gonna die. She texted her son back, calling them now. Are you still there . Answer your phone. Call me. Then again, call me. They texted back and forth. She told him help was on the way. Eddie texted back, still here in bathroom. He has us. Then later they need to come get us. Hurry, hes in the bathroom with us. Hes a terror. After that, he went silent. His mother waited for hours with no news of what happened to him. And then later that day, he was listed as one of the 49 people who were killed. Cnn correspondent Brynn Gingras joins us from new york. Were still learning about awful stories like this, this morning. Absolutely, carol. We are also learning about ways that family members are remembering those who were killed in this horrific incident. All but one of the victims have been identified by authorities. Theyre still trying to get in touch with family members before they can actually release the names of everyone. We know the names of about half of the people that who were killed. Let me give you a few of those names and few of those stories that were learning about them. Stanley almodovar iii, 23 years old. His mother left his dinner in the fridge that night so he would have it when he got home from the club. Then 25yearold enrique rios. A cousin wrote on facebook, my heart is heavy. We grew up together. Now he is gone. God took someone who was already an angel for so many people. Were also learning about Edward Sotomayor jr. , 34 years old. He had a nickname everybody knew him by, top hat eddie. He was a travel agent and always would wear a top hat on his head and actually friends and people who knew him paid tribute by posting that top hat emoji all over facebook. Thats how they remembered him. Also luis omar ocasiocapo, youngest of the victims, 20 years old. So many ways that people are trying to remember all these people that were killed. We have more names to show you. Were still working together and learning about these stories, these last moments of their lives. Also again, carol, as i mentioned, the tributes people are paying to them now that they are gone. Carol . All right, Brynn Gingras, thanks so much. I want to throw it back to erin, who is at one of the hospitals. Doctors are still treating victims. Erin . They are. Security at the entrance of all of these hospitals as theyre trying to protect these victims and families coming in to visit them this morning. Still to come, the killer at one point was on the fbis radar. Two investigations. A heated debate now brewing over who was to blame and whether something crucial was overlooked. Were warning signs missed . We have senator bill nelson, who joins us live next. When cigarette cravings hit, all i can think about is getting relief. Only nicorette mini has a patented fastdissolving formula. It starts to relieve sudden cravings fast. I never know when ill need relief. Thats why i only choose nicorette mini.

He will be briefed by a number of officials. Fbi is going to be there. Fbi director james comey along with Homeland Security director. Very dark day for president obamas presidency. He addressed the country after the deadliest mass shooting in this country and the deadliest terror attack since 9 11. Although its still early in the investigation, we know enough to say this was an act of terror and an act of hate. As americans, we are united in grief, in outrage and in resolve to defend our people. This is a scene that is all too familiar to this president. He has addressed the nation following a mass shooting more than a dozen times. You heard me correctly, more than a dozen times since he has been in office. Every time he is angry, bereft and yet very little has changed. These awful Mass Shootings go on. It did prompt a Quick Response from the 2016 campaign trail. Both Hillary Clinton and donald trump took to twitter and elsewhere to condemn the attacks, with mr. Trump hitting mrs. Clinton for not using the phrase radical islam and should drop out of the race because of it. She addressed cnn this morning in an interview. It matters more what we do than what we say. I clearly have said we face terrorists who whether you say radical islam or radical terrorism, they mean the same thing. And im happy to do so. We dont need to demonize, demagogue and declare war on an entire religion. That plays right into isis hands. All right. Before we get to donald trump i want to bring in senator bill nelson, the senator from florida, who represents this district. Thank you for being here. First of all, i would like you to react to what Hillary Clinton said about terminology. Donald trump is accusing her of not calling it what it is. We cant fight it until we all know what it is. Does donald trump have a point . Well, that point is ridiculous. First of all, were at ground zero of the grieving process. This is a time for healing and unity, not a time for division. The fact that were in this political season, recognize what ultimately the fbi will conclude. It was isis inspired and it was a hate crime. It was antigay. Either one of them is terrorism. Wasnt this mentally unbalanced man who hated gay people, and he somehow justified that hatred by looking into isis and thats why he did it, or did isis inspire him and his hatred of gay people . Thats what the fbi investigation will tell us. Clearly, he was somewhat unbalanced. Why is that distinction important . Whether he was isis inspired, its the new modus operanndi. Were going to pick up those communications. So they say, okay, you go on and do it on your own. So, any crazy person that might think that this is their jih jihad and thats where its more important on everyone else, if you see something, say something. I want to talk more about what donald trump said is the solution to this problem. First of all, we have to stop people from coming in from sy a syria. Were taking them in by the thousands. Youre going to have tremendous problems. Look at the people that have come to the country and you look at and are here. And for that, we need intelligence gathering. We have to look at the mosques. We have to look at all we have to look at the community. Of course, this shooter, i just want to clarify for our viewers, the shooter was born in the United States. His parents were born in afghanistan but have been in the United States for many, many years. So, would banning all syrians or a temporary ban on muslims coming into the country have prevented this attack . Of course thats exactly the opposite of what we ought to be doing. We ought to be unifying and let that muslimamerican community, which thinks of themselves as americans, help us find the misfits. Donald trump said were letting thousands in. We have let in 2,000. Compare that to the scores and scores of thousands in europe. The rest of what we anticipate, another 8,000, will be vetted over the course of a year before they ever come in. No, the attitude that trump is expressing is constantly divide, divide. Thats not the character of the American People and thats exactly the opposite of what we need at this time. Let me go back to what Hillary Clinton said. The terminology i call it radical islam. Theres no difference from radical jihadism, right . Thats a change in the language for her. Ill ask you that. Is that a change in language for her . I dont get involved in those semantics. It is what it is. She did say it. She is running for president , so is she more receptive of it, do you think, because of what the republicans are saying . Or she doesnt really care about terminology . Its an attempt to divide, nitpick. Its radical islam inspired by isis, period. The way we have to respond is we have got to come together as americans. Another question about the shooters target. Its a nightclub, pulse. Not very well known across the country. I talk to people here in orlando who have never heard of it. So, if isis wanted to make a splash from one of its soldiers we dont know if thats true or not why pick this club . Were in orlando. There are bigger targets to pick. This fellow who apparently is operating as a lone wolf, 100 miles from here in ft. Pierce, he had obviously cased it out. 300 people are packed into a small building. It becomes a very vulnerable target. He comes late in the evening. How he got the weapons in. Then he attacks advantage of it. In your opinion, was this a plan he had in the works for a lengthy period of time and he checked out other gay clubs throughout the state of florida . We dont know the answer to that yet. He had obviously checked it out. Okay. So, you have a lot of experience of stopping these things. What is it that you can do to stop it . Well, first of all, the fbi had looked at him in 13 and 14. The case was closed. Under their operating procedures, when that is done, that is done. But now we know when he got the guns, the background check showed no criminal record and no notation. Maybe when we have an investigation, even though its closed, there ought to be a notation so that comes up on the background check when he purchases an automatic weapon. Still the fbi questioned him twice. There was a Police Report, supposedly, according to his exwife, that he beat her. And she left the marriage because of that. Yet he was a Security Guard and even before he guns that he used at pulse, he owned a gun. How is that possible . Perhaps thats where we need to change the law. Notation is made on this persons record even though he has been cleared for the purpose of purchasing a weapon. Theres another argument going on in congress right now. If you have been on some terrorist list or been checked, shouldnt you automatically go on the nofly list . And right now, you dont have to be put on the nofly list if youre on one of these terrorist watch lists. We have a lot to do. Senator bill nelson, thank you. Appreciate it. Lone attacker pledges allegiance to isis while carrying out the worst u. S. Terror attack since 9 11. Was this really motivated by radical ideology . We
