Youre in the situation room. Were following multiple breaking stories this hour. Hundreds of students running in fear from a school under siege. This time in marysville, washington, state. North of seattle, a shooter opening fire in a high school cafeteria, killing one person and wounding others before turning the gun on himself. We have new information coming in to the situation room right now. Were following the ebola scare in americas biggest city. A doctor is now in isolation in a new york city hospital. His fiancee and two friends are quarantined. And a medical s. W. A. T. Team is deployed amid urgent efforts to track down his possible contacts. Our correspondents and analysts, newsmakers are standing by with full coverage. Lets begin with the latest on the School Shooting. Cnns tom foreman is standing by with that. Were piecing together all this information as well as we can at this hour, what happened at the school. Heres what we know about the alleged gunman. Jaylen fryberg was a freshman, a Football Player and part of the homecoming court. He was a native american. Classmates say he was into hunting. He was friendly and he was popular. And this is what we know at this point about the time line of what happened. Shortly after 10 30 a. M. , as students gathered in the cafeteria for lunch, one witness says a young man rose from a table, pulled a small pistol from his pocket and began firing. I saw three kids just fall from the table like they were falling to the ground dead. I jumped under the table as fast as i could. And when it stopped, i looked back up and i saw he was trying to reload his gun. And when that happened, i just ran the opposite direction. And i was out of there as fast as i could. Reporter that witness said he knew the young man and he looked calm, with a blank stare throughout. Students scattered. Many in the rest of the building say they thought a fire drill was under way and many ran outside. In the hallways, teachers started herding others into classrooms and ordered lockdown. Someone inside placed a 911 call. By 10 40, people were swarming the building, going room to room, placing tape over the doors they had secured so theyd know theyd already been checked. In that process, they discovered the alleged gunman. By noon, officially saying he was dead, apparently having shot himself. Officials appear confident that there was only one gunman. But at this hour, they continue going through this school room by room by room checking to make sure that everyone is accounted for and experience tells us that that process will go on for many hours before theyre confident that everyone is out and everyone is secured. Thats simply out of a matter of being overly cautious. What they have to do. This is a large school by the standards of any city in this country. There are a lot of rooms. A lot of area on the campus. They have to look for evidence, for people who may still be hiding. Thats been known to happen for hours because people are terrified by this. And to see if anybody else might have been hurt somewhere that theyre unaware of. Tom, thanks very much. Were also getting more information on the Deadly School shooting. Lets bring in evan perez. What are you learning . Reporter we know the authorities are trying to trace the handgun that was covered at the scene. That was believed to be used by the shooter. Its a. 40 caliber beretta handgun. And the atf is trying to do a trace to determine where he got it from. This is an area where a lot of people have guns. Its not clear whether he had to go anywhere other than his own home to get this firearm. But we know from witnesses he just came into this cafeteria and sat there for a little while and then started shooting. Some of them his own friends, wolf. And i take it this is a situation where fbi, federal officials, they are being brought in for assistance in dealing with this kind of a crime . Thats right. They have a lot of experience on these types of shootings. The fbi is there to try to help with some of the behavioral analysis, to try to look at some of the social media mopostings this young man. From some of the postings, it seems he was very upset in the last few weeks, perhaps about his girlfriend. He seemed to be upset with some of his own friends. Something appeared to be triggering this. Perhaps was building for some weeks and thats something the fbi will definitely be focusing on to try to see if theres anything they can learn to try to prevent these types of things from happening again. Which is also smart. Thanks, evan. Joining us on the phone is Sergeant Ryan dalberg, a spokesman for the everett, washington, police. Sergeant, thanks for joining us. Lets review some of the facts as we know them right now. I know maybe this is still a fluid situation. First of all, how many people were shot . Im sorry. You cut out on me there, wolf. How many people were shot . We can confirm six injured, two of those being deceased and the other four injured. One of the deceased being the shooter himself . Correct. And we have confirmed this is a freshman, Jaylen Fryberg, is that right . I dont have official confirmation on the shooters identity. Thats coming through social media. Do we know if all of those who were shot, one student shot allegedly by fryberg and killed, four others and injured. They were all students, right . I dont know. I cant confirm whether a teacher was shot or not. I dont know. Do you know if they were shot at random or was this a deliberate were they targeted . I dont know if anybody was specifically targeted or if it was random. Were still trying to piece all those details together. What can you tell us, without mentioning his name, since you obviously dont want to mention his name, because were getting all sorts of information about the shooter, homecoming king, if you will, active on the football team, a native american. Can you tell us anything about him, about a possible motive, for example . No, unfortunately right now, i do not know a motive. Were trying to piece that together. He is an active student or was an active student at the marysvillepilchuck high school. And at this point, were still searching for a motive ourselves. You can confirm that the shooter put to gun to his head and killed himself . I cannot confirm that i dont know. You dont know. Is it possible somebody else killed him . Is that what youre saying . I dont know, sir. I have not received any of those type of details one way or the other. Were getting some pictures in from the school. Police still going in there. Is there a search possibly for someone else . Yes. Basically a back search is our standard procedure. Our initial teams will go in and if there is a threat, theyll address that threat. And once thats taken care of, then theyll move to escorting any injured people out of the building. Once thats completed, were going to our teams will go back slow and methodical and do a very, very thorough and careful search just to make sure the building is safe. And to make sure that no one out of fear is still hiding there in a closet or in a room xlais somepla someplace, right . Thats correct, sir. This is being done out of an abundance of caution, add they say . Correct. Theres no hard evidence that there may be someone at large, another shooter or suspect at large, right . Thats correct. We take all precautions we can to make sure everyone is safe. Let me get back to the motive for a second. I assume youre going through social media, the comments by this alleged shooter. Can you share anything with us on that . What i can share is that our county mutual Investigative Team is on board. Theyve been called in. Thats a team of special investigators that will be conducting those types of inquiries. And its a team that all agencies in this area put together or contribute to and they have specialized training in homicide and serious event investigations. Were told by sources that federal Law Enforcement is now tracing a beretta. 40 caliber handgun. Is that the weapon that was used . I dont have any information on what type of firearm was used in this incident. Im sorry. And you have no idea where the shooter got the gun . None at all. Sorry. Is there anything else you can share with our viewers, sergeant dalberg . Not at this point. Anyone commander lamoureux is going to bring an Additional Press conference probably in about 20 minutes. And hopefully hell be able to add a little more. He was just up at the scene about 20 minutes or so ago. Hell be addressing the media at about 1 30 our time. 2 30 your time. That would be 5 30 here on the east coast in about 20 minutes from now. Yes. Sergeant ryan dalberg, well stay in close contact with you. Well cover the News Conference with the police chief at the bottom of the hour. Tom fuentes is here with us, our cnn Law Enforcement analyst. What do you make of whats going on right now . Its another one of these mysteries, really, what was going on in his head to make him decide to go to that school these types of issues in somebodys brain usually brew for a while. And each thing they think they were wronged or disrespected adds another on top of another and finally they decide to take action. Obviously he planned this, he brought the weapon hidden in a backpack to school. Walked around the school all day and from what earlier witnesses said, it sounded like at the cafeteria, he went specifically to the people that he initially shot, went up to them from behind, shot each of them in the back or the back of the head as if he had been stalking them. And they were identified as friends of his. So we dont know what he was thinking or why or what kind of delusion he had as far as what people thought of him or what they were doing to him to cause him to believe that he had to take this action against them. Based on these initial, i repeat initial, eyewitness accounts, because this could change, he didnt just randomly start shooting at some people, he deliberately targeted individuals. Yeah, this is from someone who knew him, said he knew these individuals were friends of his. He knew them to be close to him. And it appeared to him when he came into that cafeteria, he went to the victims, picked them out and shot them, that it wasnt just that he was wildly shooting at anybody that went by. Very weird story because normally in a situation like this, the shooter is disgrunt d disgruntled, angry, no friends, loan loner. In this particular case, this individual is described as popular, Football Player, homecoming king, freshman and all of a sudden this happens. Were going to get more information. Stand by, tom. Well hear from a witness, an account of the Deadly School shooting north of seattle, washington. Also speak with the washington congressman, Jim Mcdermott. Plus, the ebola scare in new york city. A doctor is now in isolation after testing positive. His fiancee and two friends are in quarantine.

Head for the cemetery were following the breaking news, a Deadly School shooting just north of seattle, washington. Law enforcement officials telling cnn, a gunman opened fire at the marysvillepilchuck high School Shooting five people before turning the gun on himself. Were told the gunman and one of the people he shot are dead. Three of the injured students have head wounds and a fourth was shot in the jaw. Fellow students, including witnesses, identify the gunman as Jaylen Fryberg, a freshman and native american. Moments ago, a student who was in the cafeteria when the shooting started described what he saw. It was just a big group of kids. The whole table was filled up. Big round table right next to the door from the cafeteria. I was sitting at the table right next to the round table. And i was just eating my food. Id just got done eating my food. He was quiet. He was just sitting there. Everyone was talking. All of a sudden i see him stand up, pull something out of his pocket. At first, i thought somebody was making a loud noise with a bag until i heard a loud pop. I heard four more after that and i saw three kids fall from the table, like they were falling to the ground dead. The student says he managed to run out of the cafeteria when the gunman stopped to either reload or that gun jammed. Joining us in the situation room, congressman Jim Mcdermott of Washington State. Congressman, what are your folks there telling you about what happened at that high school . Im really only privileged to know whats coming on the official media. I dont have any information from Law Enforcement people or the fbi or anybody else. I know what you know. Tell us about this area. You know the area well. Tell us about the high school, what kind of people live in that area. Its not a stereotypical place youd think Something Like this might happen. This is an urban, rural area, lower middle class, middle class People Living out there. It is not an area with lots of urban violence that you might be accustomed to in other places. Its surprising and this youngster does not fit the stereotype. He seemed to be someone who was popular, got along well, was doing well in school, well in athletics and so forth. So obviously tles a whole story we dont yet know. You have to feel sorry for not only his family and the family of the children who were injured. But the situation is hard for anybody to get their head around because you would never think it would happen at marysvillepilchuck school. You would think in chicago or someplace like that. But not out here. A lot of schools nowadays, an increasing number, congressman, have metal detectors when the kids, the teachers, they go into those schools. Do you know if this high school has metal detectors at the door . I only can guess. And my guess would be they do not. Its just simply not a place where peoples minds are tuned to that as a real threat to their daily existence. Everybody thinks that kind of thing is going to happen somewhere else. And this certainly would have been one of those places where you people that move out from seattle and say, i want to get out of the inner city, i want to get out of the tumult of living in urban life, its going to be quiet out here. And thats really the nature of the area this occurred in. Thats what makes it kind of hard to makes it very hard to understand. As you could imagine, im sure this is going to revive the debate in the United States about the availability of guns. Whats the situation over there in Washington State where you are . How easy is it to get guns nowadays, especially if youre a 17 yea 17yearold kid . Youre bringing up a very interesting thing. We have actually on the ballot, a state initiative to require background checks at gun fairs and the loophole that presently exists in the xwun law. Most people in the state of washington have given up on the congress ever doing anything about it. I was there in 2002 when we had the assault weapon ban that occurred on a a School Shooting that occurred on a schoolyard in california. Theres lots of guns. And people dont feel like theres any interest in the congress to do anything about restricting or requiring gun locks. Weve had some proposals made in the state legislature. But theyve never been able to get the votes. The nra controls this area as well as they do the congress. Congressman, our deepest condolences to everybody out there near seattle and Washington State. Horrific, horrific situation unfolding there. Congressman Jim Mcdermott, democrat from Washington State. Thanks very much for joining us. Weve got an eyewitness to what happened, a freshman at the high school is joining us. Rachel, where were you when this was all going down . I was about 60 feet away from the table he was sitting at. And if its not too painful, tell us what you saw. Well, i was sitting at lunch. I was eating my lunch. And i heard this big bang. And i thought possibly it was a bag that blew up or a balloon. So i turned back around and minded my own business. And then i heard it about another four times. And i turn around and i saw him standing there. I saw the gun in his hand and everyone just ran. So i just ran with everyone and thats all i saw. I didnt really see much. Did you know this was Jaylen Fryberg . Yeah, when i saw him, i was like, oh, my gosh, thats jaylen. I would have never expected it would have been him out of all people. It was really heartbreaking for me to see that. I saw him with a gun in his hand shooting. Did he say anything . Did you hear him say anything at all . I didnt hear all i heard was people screaming, run, get out of here, lets go. I didnt hear his voice specifically, no. You knew him. So tell us a little bit about Jaylen Fryberg. Jaylen fryberg was a really nice person. He was a person who was always he always liked pleasing people and he was a people person. He liked he rea
