Island. White house Officials SayPresident Trump has been briefed. The new York Police Department said this all started a little more than an hour ago, Police Sources telling cnn they believe the shooter is a former employee. It is unclear what work that person may have done at the hospital. The bureau of alcohol, to back co and firearms just tweeted they have special respondents responding to the scene. Jason carroll is here. What can you tell us . This entire incident began just a little bit before 3 00. Thats when the calls first started coming in with what was then an active shooter. Getting word that in the past few moments the shooter is, in fact, deceased. It is unclear how the shooter died. Did he die of his own hands or died at the hands of those who were there to stop him . That at this point is unclear. Also getting word that perhaps this shooter was a former employee there at the hospital. That is still something that is being worked on, being confirmed. Nypd telling us anywhere between four and six people have been wounded. The extent of their injuries at this point not clear. Again, atf, nypd, also including the Hospital Private security force, they were all there to assist while all this was going down. Just to get some folks a little bit of context here just how large this hospital is, bronx lebanon hospital, 972 beds. Last year treated some 138,000 patients, so its a large facility. So you can imagine the challenge that these First Responders had when they first got word that there was, in fact, at one point an active shooter there at the hospital and what they had to do to try to end that situation. But once again, it appears at this point as if the active shooter has died. Once again, unclear if he died at his own hands or died as a result of those who were there to stop him. Jake . All right. Lets go to cnns hrkshimon cnn shimon pasquerav. Is there indication of another shooter, perhaps . There is no indication of another shooter. They believe theyre dealing with this one shooter who they believe to be a former employee. Thats according to in the process of cleerlg it, making sure there are no other shoorts that we would expect in this situation. Were also being told that they want people to use. Theyre anywhere from 4 to 6, or may maybe. Theyre trying to make sure they can treat all the injured, jake. And shimon, one of the things thats so alarming about this incident is it takes place but this one inside a hospital where people are supposed to be protected, this one is supposed to be Getting Better who weve been told were shot. Ive been to that hospital before. Usually hospitals in the city are not as closed off and probably have access he probab probably. If he was a former employee, maybe someone recognized him and he got in. We dont know how he got in yet. Weve not been able to say for sure 100 if this is a doctor or what kind of employee. They just have not told us who he is. Thanks. Keep bringing us more reporting as you get it. Director of cnn Law Enforcement analyst. What do they decide to do . Typically, jake, they have to try to decide how many shoorts in the building . Have they escaped and run down the street and then, of course, the main thing is making sure they can find every victim and get medical care for everyone who needs it, rescue any of the injured parties who are inside there. So they have a crime scene, people sperch. Theyre trained for it, they practice for it. A few months ago we had the call of an active shooter and thats at the san diego medical naval complex. But if this is similar, you had somebody going to the scene of that hospital wanting to shoot a particular person or a particular group of persons, whether its a former supervisor or coworkers or just general employees or patrons or patients because theyre mad at the Hospital Management itself. But it mos more of a personal matter and not a global type incident when that type of thing occurs. That is one of the immediate considerations, how to secure that, how to fill it at the scene when you get there. A reminder to my viewers. Youre looking at bronx lebanon hospital where a shooting took place just before 3 00 eastern when the request for Police Assistance went out. We are told four to six people have been injured. They put out one tweet earlier saying one shooter was shot at the scene. Peter macdonald saying one shooter is shot at the hospital. Hes saying one shooter, not the shooter. There may be other shooters, for all they know, but its to remind everyone that the early stages of a crisis like this. Theyre being very cautious, very circup. And to respond that there was only one shooter and that shooter responded. The police are not going to accept that as facts, theyre still going to search. Until they tucked tall employees, so other employees who may know this former employee. Until they review all the Video Surveillance of the hospital and in the hospital, you know, at that point they may be willing, you know, within a few hours to rule out that theres anybody else involved, that there are multiple shooters. But certainly at the beginning of this, theyre not going to take anyones word. One of the challenges for police right now is they obviously cannot leave the scene i mean. They say they know definitively there was only shooter. No, thats right. In every one of these incidents, they have to do an entire building clearing operation, and oftentimes it can take one to five hours depending on the size of the building. That person, if you went in there with help, with other shooters, would know exactly whe where. Someone visiting the hospital would never know about it, never see. Yeah, they have to take that into consideration. On the other hand, uf a great Police Department, nypd. All the help they need theyll get from. To la theyre able to help go through witnesses, interviews, look at videotapes. They will be able to bear an enormous amount of resources to bear immediately and already have, no doubt. That helps in the situation. But yeah, the building clearing of a hospital and properly neighboring buildings is quite an undertaking and will take some time. If youre just joining us, youre looking at images in new york city north of manhattan in the bronx. There was a shooting there sometime, we believe between the 3 00 and 4 00 eastern. Law enforcement authorities are being very circumspect with information they are sharing. Lets bring in art roderick. Hes a former city director with the u. S. Martials office. The first thing is to bring in the security along with the nypd. Theyve probably dealt with these circumstances. The security running the hospital probably has the best idea of whats going on. So you have a combination of security working with nypd but also a group of detectives or Police Officers actually viewing the videotape. These hospitals are videotaped very heavily with sophisticated type cameras, and to follow that individual around as quickly as you can to figure out, is he coordinating this with anybody, is he on a handheld . Is he on a cell phone . Well, hes going to through this whole scenario. That will help you determine. Unless theblg 10 they can confirm 100 that the shooter is down, they cant do that until theyve searched everywhere. Would the local policemen be there or do you have their own armed security. A lot of the Law Enforcement officers, but a lot of them do have their own armed security. Im not sure about this particular hospital, but a lot of them will drill with the local Police Departments on active shooter scenarios. Art roderick, stay with us. We just learned that mathe mayo of the city, mayor de blasio, is headed to the scene of the shooting. Lets get back to jason. Jason . Reporter were expecting a statement from the hospital. About 30 minutes from now, the mayor was briefed this afternoon as the dwolts were unfolding there from the hospital. We should also know from the reports were getting, anywhere, once again, anywhere from four to six people who were wounded, the extent of their injuries at this point unclear. What is also unclear, jake, is who these people, these victims are. Were they patients, were they doctors or nurses at the hospital . Thats something that wasnt reviewed at this point. Were going to be reviewing security cameras at the hospital, so well be getting any information that we can once they are able to view those particular cameras. Again, its a large facility, as i said before. 972 beds there, 138,000 patients were treated there just last year, and im just going to get some new information here for you, jake, here. Apparently a Law Enforcement source tells us that the shooter died from a selfinflicted wound and that there was a victim found next to him, a female victim found next to him. Apparently that female victim died from her wounds. This is information now just being handed to me as we speak. Once again, Law Enforcement source telling us that a shooter died from a selfinflicted gunshot wound and found next to him, a female victim unidentified at this point but certainly we had already told you that there were four to six people who were injured now. Unfortunately, you have to report that one of those victims has died as a result of what happened there. And the shooter, we were already told, or a shooter, was dead at the hospital. We assume its the same shooter who took his own life at the hospital and was taken and is at the same exact hospital. Lets go back to sam fuentes, of course, the former fbi assistant director. Tom, when the police entered this, how do you secure a hospital like this . You have to stop everybody from entering and exiting . How do you do that with a hospital . You do it. The people who are deadridden cant go out the door, so toyou have so make sure theyre safe ask secure. You cant just evacuate the building. It would be more dangerous to move them than to try to protect them. In this situation, if the reporting is true that the person died, the shooter died of a selfinflicted gunshot wound, then thats going to be about a 95 situation of being just one shooter. Youre not going to have a shooter gather up a bunch of friends, go in and all of them commit suicide. Its a pretty good indication that police will probably clear this entire building in a pretty short order. By the time theyve looked at the Video Surveillance, by the time theyve talked to the surviving victims and have them describe, was there more than one person . Was there someone with the shooter . Was he shooting at you . If they hear its pretty much just one person and that person has killed himself, this is going to be declared over pretty soon, and then its just a crime scene and the forensic people will have hours and hours of work to do afterward. I dont know if youve ever worked a case at a hospital before, tom, but in a situation like this would emergency room patients, would ambulances be diverted to other hospitals or would they be told not to come to bronx lebanon . Sure. They would be broadcasting, the police would be aware, the emergency services, Fire Department and others would be aware that they have a potential tactical danger situation at that hospital and absolutely they would be diverted to other Emergency Rooms. Were not in a situation of response of a catastrophic event like 9 11 where every hospital in manhattan and the bronx and queens would be jammed potentially with people coming in. So in this situation where its fairly routine business for most of the hospitals in new york city with the exception of this one hospital, it wouldnt be that big of a problem to divert incoming patients to a nearby hospital if theyre coming into Emergency Rooms. Art roderick, formerly of the u. S. Martial service, let me ask you, if the reporting and information were getting is correct and the shooter took his own life, does that change the calculation for Law Enforcement as they seek to secure the building, as tom fuentes was suggesting . I agree with tom, it absolutely does. It sounds to me more like a domestic type situation than anything else. Its just going to be interesting to find out how those other four or five people were injured. Were they injured trying to get away, or did he have to actually inflict other wounds on individuals to get to the target individual that he wanted . It sounds like to me that this was more like a murdersuicide type situation than anything el else. More than likely, Law Enforcement already has in their mind why this occurred, what medical situation theyre handling, and they wont have to do this massive type of terror response weve seen in other cases. Would that mean the police would not need to clear the building and check every room . Theyre still doing that as standard protocol. You asked the question about them diverted to other hospitals for Emergency Rooms and medical care, and thats automatically built into their standard security protocols. So theyre going to finish their active shooter protocol which means theyll be clearing that whole building and making sure everybody is okay. Im sure there is a lot of individuals that work at the hospital that are sheltered in place, that are locked behind doors and Law Enforcement is going to go around and make sure every one of those doors is cleared, every one of those rooms is cleared. If youre just joining us, youre looking at live pictures from the bronx, new york. There was a shooting earlier this morning at bronx lebanon hospital. We were told four or five people were injured. We are told one person is desho inside the hospital. Were told that shooter took his own life, apparently, with his gun. Next to him was the body of a woman. The police are still investigating the scene. They are presumably going room to room and making sure there are not any other shooters, there is no other danger. Presumably theyre also looking at surveillance videos to figure out what happened exactly. Obviously with a giant hospital such as this, the sooner that they can reopen it for the citizens of the bronx and manhattan the better. But that is the status as of right now. Shimone is one of the reporters reporting on this story. Shimone, what can you tell us . Shimone, can you hear me . Were having problems with shimones communications. Lets go to Jason Carroll right now to get us up to speed. You were telling us that mayor bill de blasio has been briefed and is on his way to bronx lebanon hospital. Were also told President Trump has been briefed in the white house. What more do you know . Just a little more, jake, on whats been happening. We are told once again that one person, a female, was killed during this incident found next to a shooter who was there at the hospital who apparently died from a selfinflicted gunshot wound. We are told that there are five now other victims as well. Unclear about the identity of those victims. Are they doctors, nurses, other patients . That skill unclear. Well get you confirmation on that. We can tell tu three of those victims are in serious condition with gunshot wounds. Also told from the source r. Unfortunately, there happened on the 16th floor of the hospital. He was wearing a lab coat and also had some sort of i. D. On him identifying someone as well. One of the witnesses describing blood on the walls, blood on a staircase at the facility as well. So a horrendous scene there at the hospital. And you also have to imagine what investigators are dealing with at the hospital themselves, the folks who work there. Not only do you have an active investigation going on there, but you also have hundreds and hundreds of patients that need to be treated as well there at the hospital. But once again, five other victims. Three of them are in serious condition with gunshot wounds, one victim deceased, a shooter. Cnn Law Enforcement harry touki. Obviously the information is fresh and we are expecting a whole lot of other information. The information we get later from nhk, the body of the shooter is dead as well as a female victim next to him. They found out the shooter killed himself and he killed the woman who was next to him. It seems to me there needs to be a close look at the relationship between that woman and that shooter. You have five wounded. I dont know if their wounds are life threatening or not, but its a clear indication to me there may have been some type of relationship between that woman and that shooter. Of course, i cant tell you 100 . The investigation will clear that up, but i think thats going to be one of the things i would be focusing on right now. And also the fact that, you know, a Police Informant could probably ascertain quickly if there was another shooter. We could see a disgruntled employee orl love triangle or Something Like that. Protocol is to go ahead and search that whole hospital for a second shooter that it looks like doesnt exist. Theyre looking at that video, and they can see there was only one shooter that came into that hospital, committed the carnage they did on the 16th floor, and im sure one of the bosses are going to make a decision as to whether or not the Police Department should consider searching the rest of that hospital, because it is so big. But the good thing about the nypd is that they have the manpower. Even if through i think moers likely some boss is going to make the decision that this is over and its now being treated as a crime scene. Harry, let me just ask you were looking at live pictures right now from medical responders, others to be particularly alarmed or on a state of. Do you recall when you were walking by and you saw people perhaps not looking overly concerned, do you feel the situation is now over . Its now a crime scene. The odds of having a second shooter when the video. Heres a guy who came in and it looks like he wants to commit a certain amount of carnage and talking to negotiators planning his way out. So i think he went in there, killed six or seven persons, and then killed himself. Which we see time. The love relationships that the shooter really does kill him
