His school into a war zone. Police say 17 people were killed in and around marjorie stone ham douglas high school. At least 15 others are hospitalized. Five of them with life threatening injuries. Were waiting to see what their condition is this morning. And in just hours, this 19yearold suspect will make his first court appearance. He is hes been transferred to the Broward County jail. Youre going to see new video right here. This is him in the wee hours of the morning being transferred. As you can see, hes in huffs and hes being walked in. These are the first shots we have of him in custody. Investigators already finding disturbing social media posts from this suspected killer. As cnn learns he was getting treatment at a Mental Health clinic. And he legally purchased the ar15 that he used in this massacre. So is, again, were seeing the nexus of Memory Health and ability to get weapons. So this attack of course is reviving the gun violence debate. Can congress do something this time to stop this carnage in schools . Lets begin with cnns rosa flores in parkland, florida. Rosa . Reporter good morning, alisyn. As you mentioned, weve learned that the suspect will be facing a judge later today. Behind me, investigators scouring, processing the scene and also reliving the horrors of this gunman and what he left behind. Oh, my god terrifying moments unfolding inside this florida high school. A gunman bran dishing an ar15 style semiautomatic weapon, opening fire, killing at least 17. There were tears. There was crying. Some of my classmates did not know if they were leaving the school alive. Reporter the fire alarm sounded minutes before the end of the school day. The shooter wore a gas mask and he had smoke grenades. He went and set off the fire alarm so the kids would come pouring out of the classrooms into the hall. There the carnage began. Reporter students and teachers confused because only hours earlier they had done a fire drill. Everyone thought it was a joke. Then the game shots came about. I heard screaming. I heard about five, six gunshots. We thought they were firecrackers. Reporter faculty alerting the school that an active shooting was under way. Some running for their lives, others hiding under desks sending frantic Text Messages to loved ones. She said tell them someone is hurt on the third floor. Reporter one student hiding with with 19 students in a closet for nearly an hour. I was praying, praying, praying. It was the most scariest experience of missed life. Reporter police desperately attempting to locate the shooter. Did he know where the shooter is . We dont know, but were already in the building. Reporter this shows students huddling on the floor when the s. W. A. T. Team lives. Police, police. Reporter outside, First Responders rushing to help the injured while anxious parents waited to be reunited with their children. He said, mom, it was real. It was really real. Reporter of an hour after the shooting began, Police Arrested him in a neighboring city after fleeing trying to blend in with the crowd. He told me how he got kicked out of two private schools. He was held back twice. He had military aspirations. He enjoyed hunting. He always seemed quiet and strange. Reporter investigators now looking for answers in the suspects online posts. Police uncovering these disturbing images of the suspect on instagram, showing him bran dishing a knife and holding what appears to be a b. B. Gun. And a target riddled with bullet holes. Now, it could take investigators days to process the scene, alisyn. Think about this. According to the sheriff, this crime scene begins outside of the school. The first body was found by the street. They found two bodies outside the building. Of course we know 12 others were found inside. Alisyn . Yes, rosa. Because this school had something unique. It had outdoor hallways where kid would change classes. It makes it just as complicated. Lets turn to charles ramsey. Commissioner, thank you so much for being with us. Investigators now have to look for signs. They start figuring out were there any signs . Were there red flags that were missed . Who is this suspect . What trail of bread crumbs did he leave . And guess what, there were some. At this point in the investigation, hes alive. So they can interrogate him to get digital footprint through social media. He left a big digital footprint. He said online i want to use my ar15 to kill people. Someone had to know something. The question is who knew what, when and could it have been avoided. Doesnt that lead us to the background check. As far as we understand this suspect legally purchased his ar15. He passed a background check a year ago. So are background checks not looking into social media . I dont believe they look into social media at the present time. How is that possible . Well, maybe they need to. Again, its whats practical and whats required by law. So it was too easy for people to get their hands on assault weapons and other types of weapons. Listen, this guy was all over social media. He had youtube videos. He had postings of disturbing violent things. He took pictures of himself brandishing weapons. Are you seeing in order to get a gun in florida, whoever approves the background checks dont have to look into somebodys digital footprint . I cant say with 100 certainty, but i dont believe so. I dont believe so. That doesnt mean they shouldnt. That doesnt mean in the future we shouldnt rethink exactly what goes into a background check. But the bottom line is too easy for people to be able to purchase weapons, especially assault weapons. What does an 18 or 19yearold need with an assault weapon anyway . Some of this ammunition can be bought online. You know all about this. I know that you ive heard you talking that you dont have much faith that lawmakers can do anything about this. But that doesnt seem possible. Surely there must be something we can do to protect your teenagers in high school. Well, theres something we can do. But to rely on congress to do it, were not going to get anywhere with that. I have zero confidence that theyre going to do anything. If sandy hook didnt move the needle at all, theres no way i think this is going to move the needle. And its going happen again. This is not going to be the last School Shooting or mass shooting we will have to deal with. Its just not going to happen. Can you tell us what was happening with investigators and policemen. They showed up and its chaos, of course. They get the call of shots fired at a school. They have to figure out where the gunman is, is there still an active shooter. There was chaos and confusion of course. Some of the kids who hid in a encloses he et the better part of two hours. Just explain what happens when police get this call. Well, Police Departments across the country have gone through active Shooter Training. We learned at columbine we cannot wait for s. W. A. T. To arrive because while were waiting, people are dying. They go in and try to neutralize the threat. Three things people need to do in a situation like that. First is run if you can. Get out of there. The second is hide, barricade. If youre in there two or three hours, so what . If you survive, you survive. And the last is to fight for your life because thats literally what youre doing. Commissioner, isnt this just a little sick that this is the advice were giving to all of the students across our country . Were telling them to run like hell, fight. This is not what high school was designed for. This campus was an indoor, outdoor open campus. You are looking at video how terrorized the kids were. They thought they were just going to school in this day. There is this cell phone video of everything that transpired in their classrooms. It is not just a little sick. Its very sick. It is the reality of our society right now. Until we stand up and do something about it, it is not going to change. The only question is when and where its going to happen again. We can hear theres actually some video taken look, all kids have cell phones now. There is really horrible video from inside the school. This is the video where you can hear actually the audio of the ar15 firing. So lets listen to this. Holy oh, my god all right. Listen, its too horrible. Its too horrible to actually process. You can hear the kids trying to process it, not knowing whats happening, bloodcurdling screams. I know you say there are answers. What is that . Having metal detectors at schools . What would you do . If you were in charge, what is the next thing to do to keep kids from having to endure this horror . Well, there has to be a strong stand. Pass some kind of legislation and enforce it. In order to make it difficult for people suffering from Mental Illness or having some other types of issues. Think about it. You could be on the nofly list and go out and buy a gun. That is absolutely insane. There is legislation floating around in congress to make it easy to purchase silencers. Now, look at that video and think what it would feel like if he had a silence other that weapon and how long it would take for kids to react and know whats going on. How many more lives would have been lost . To me its insane that you would even think about doing Something Like that. Yet thats reality in our society today. Its got to stop. And the only way its going to stop is if americans stand up and say enough is enough. You legislators, we did not put you here to do this, and youre going to have to do something. But i dont think its going to happen. We have had this same conversation, hideous deja vu over and over again. After las vegas, we talked about bump stocks. It can turn a semiautomatic into an automatic weapon. Congress dragging their feet on that. To your point about the Mental Health component, we know this suspect did have a Mental Health issue. He was in a Mental Health facility sometime. How can they not figure out the nexus, if youre in a Mental Health facility you shouldnt have guns. He legally purchased the gun. Whats the Mental Health clearance . But thats my point. He legally purchased. So its not as if nobody knew he had a gun. Hes undergoing Mental Health treatment. Weve got to find a way to protect vie sraes and people to an extent. But at the same time make sure this is a person right now who should not have access to this weapon. Maybe a year from now, two years, thats okay, but not now. Commissioner ramsey, thank you so much for being here. So, chris, listen, if you can hear my frustration, you and i have been here too many times before. Obviously its a different town with a different name. This one is parkland. Its a different school. But there are 17 families who arent getting their loved ones back. We ask the same question. We always say what can we do . The challenge for you and i will be to get different answers out of people in power. Chris . Maybe, maybe not. I think at this point the job is what youre doing right now. Youre there. Youre letting people know what matters about what happened. What happens after this say much tougher part of the conversation. Because the ultimate frustration is we never get to step one. Step one after any kind of crisis is what do you do about the crisis . We have never had that question meaningfully addressed in this country in my time. And i dont think theres anybody here who has been to more than i have. What do we do about the shoo shootings. Charles ramsey said it. But we havent had the change. Thats the frustration. Listen, obviously you know. We have asked all sorts of lawmakers to come on to do to have the conversation. Lawmakers say too soon. It is not courteous or respectful. Were going to have that conversation today. Look, you can call it out as what it is. Thats b. S. We heard it after vegas. Bump stock. Charles ramsey talking about the application of silencers and what difference, god forbid, this young man had had one of those on his weapon. It was too soon. Have we ever discussed it next . Never. Alisyn, youre in the right place at the right time. Well be back to you in just a second. So, look, youve seen this picture before. Youve seen schools like this before. Youve heard the thoughts and prayers stuff before. You have seen the families. So what happened . Why did this guy do it . Were not going to name him. Now it is an official rule. Why . There is no good reason to name who commits these acts. Figuring it out how it could have been prevented, thats a meaningful conversation. In this case maybe, maybe it presents so many glaring missed opportunities that maybe somebody of conscience somewhere with power will decide to act. Well tell you why that is such an obvious choice next. Doing it yourself or tagging a friend thing. More revolutions in the making thing. That play like a girl thing. That fourlegged friends thing.

Just hours from now the suspect in the Florida School massacre will be in court. Investigators are now combing through social media accounts for clues, and there are a lot of them. We know the alleged gunman was expelled from the school you see behind me, managrjory douglas. Jessica . Reporter the gunman was taken into custody outside the school. We are told this morning he has been talking to investigators. Besides what theyre learning directly from the gunman, officials have searched many things, including gun records and also social media for clues here. A u. S. Official tells us the shooter did purchase the ar15 himself sometime in the past year. And he did pass the background check to purchase that weapon. But the warning signs were definitely there on a variety of social media posts. We have seen one of a shotgun, him brandishing a pistol which appears to be a b. B. Gun. And of course these threatening comments that he posted under youtube. I whana shoot people with my ar15. I wanna die fighting killing bleep ton of people. I am going to kill Law Enforcement one day. They go after good people. And we are learning the adopted family is coop indicat coopera. His mother died a year ago from the flu. His father died 14 years ago. And this gunman did purchase this ar15. And we do see there he was taken into custody. We know he is talking with investigators. And, chris, this morning we have learned that the gunman has been transferred to county jail. We know he will make an appearance in court a little bit later this morning. Chris . All right. Appreciate it, jessica. Its almost always obvious in retrospe retrospect. The frustration, pain ends up being, why isnt anything done to make it different the next time . We have this conversation for the people affected most and the people who may be in the future. Those are the groups to protect. Lets bring in cnn analyst james gagliano. Tell me if im wrong. If any other type of criminal event, in the aftermath, the immediate assessment is why did this happen . And then, what do we do the next time. Look at terrorism. Oh, the guy drove a car. How did he get the car on the sidewalk . We deal with barriers. They bought these kind of materials. We have to deal with that. How did this person get in this country. Then we deal with that. Not here. Whats the difference . Chris, i look at this from a military perspective. Theres the tactical level and the strategy yic level. We figure out the nuts and bolts and mechanics how to deal with this. April 1999, columbine. We adjusted the tactics. Going to the sound of guns is what we needed to do instead of waiting for the perfect Law Enforcement plan. At the strategic level, which involves politics and a lot of other things, the problem there is we have two die metric ally opposed. They go to two separate corners. I get that but it is the end of the discussion. We are not at a consensus of wanting to stop the next one. We have a president right now who hashtaged make America Great again. I dont think it ranks uggerly in any other category than School Shootings. The conversation we just had is complacency kills. We have been complacent on dealing with this issue. Jimmy, to your point, gun and control, its like jumping on the third rail of a subway. Nothing good is going to come out of it. Lets look at what we know. He was all over social media saying horrible things. You cant do anything about that. If you see something, Say Something. Maybe he gets a call. Maybe he gets a visit. They dont have the tools and resources to do this every time. He was getting Mental Health treatment. The governor is actively fighting. Governor scott is actively fighting a federal court that overturned a law in florida that you cant as a doctor ask if someone has firearms. You get penalized for something. Does that make sense . Youre a gun guy. Youre in the fbi. You believe in the Second Amendment. I do. Does that make sense . I had this argument last night with don lemon. The argument becomes as soon as you mentioned Second Amendment. It came on light in 1791. The blowback i get is you have to understand that weapons evol evolve. The purpose is for citizens to respond to a potential tear ran cal government. My counter argument is you have an ar15. The government has nukes. You are not going to win that one. If that is the premise, we have to have a commiserate response. If youre going to have a fight of what kind of weapons you want. It is who gets them. He is getting Mental Health treatment. If youre not adjudicated mentally ill, which very few
