From that campus at about 10 48 this morning. Until we can confirm what if anything occurred, we will maintain the perimeter and continue to try to pinpoint the source of the location of the sound that was heard. If necessary, go building by building, office by office in clearing those buildings to ensure it is safe. Jenny any idea where that 911 call came from . Somebody inside the building . Any idea where that call originated from . I am sure that First Responders and investigators on the scene know that. Working with the dispatch center at walter reed. I have not been given that information. Jenny about how many officers of Montgomery County can you estimate are assisting . Many officers are assigned out of the Second District which covers the greater bethesda area which encompasses that camera the campus. All on duty tactical officers responded as well as, we put a call out to the other five Police Districts within the county to send a certain number of officers to assist. Maryland state police. Im not sure but probably other federal Law Enforcement as well. Jenny we have crews on the scene and a photographer had his camera up live and we saw Police Officers escorting about a dozen people outside the front of the building. Do you know of any sort of evacuation being done for parts of the building or are people being told to shelter in place . I spoke with the pi oh covering that area pio covering that area three at they have put a shelter in place for their employees. I also know that they are escorting employees from some of those buildings as well. Jeff thank you very much for joining us. Enormous Law Enforcement presence going into the area. Walk us through the mindset of these officers as best you can tell, going into a situation like this. The unknown is a great factor, especially after this just happened in washington. What are these officers thinking now . Capt. Starks they are leaving their minds open to all possibilities. They cannot discount anything in order to be safe. As people are being encountered and approached, officers know this could also be a potential person with the intent of violence if indeed this is going on at this location. They are treating everybody professionally and being cautious. They do not want anybody to slip through for being taken from the buildings and released to a safe area where they will be debriefed. Jeff one more question about the physical layout of walter reed. What challenges did this location present for Law Enforcement . Capt. Starks i do not specifically have a lot of knowledge about this campus this large. It has a lot of buildings. It is a medical facility. Some portions have limited access. All of those things are challenges to those who are responding. Jenny thank you so much for joining us this morning. We know the Montgomery County officers, we see more Police Officers coming into the building. We know that there are road closures. Lets get over to Jamie Sullivan for the latest. Jamie we have closures in this area. The biggest is 355. I want to start off in bethesda. This stretch between cedar lane which is going to be north of the Walter Reed Medical Center and adjust south is jones bridge road. And just south is jones bridge road. I will to take a live look in this area and show junior south drive where it is blocked up. As we take a live look, no traffic gets to this area in either direction. We did have a lot of cars about 15 minutes ago in here. They were letting everyone stuck in his traffic out. Right now we are blocked off. As far as giving around this, lets talk alternates. For you traveling northbound on 355 from the chevy chase area, you can take connecticut avenue. Use that instead of getting onto wisconsin and 355. If you will be heading southbound from the rockville area, same thing. Connecticut avenue instead of 355. They are not letting any traffic through on 355. We will keep you updated on these closures. Jenny within the past few minutes navy. Mil posted a brief statement confirming that Naval Support activity bethesda is currently in lockdown and all base personnel are sheltering in place as a result of unconfirmed result of an active shooter. Dod security force, nih police force and medics have responded and are searching that area. The official statement on your screen was posted at 1145 at 11 45. Captain paul starks, with the Montgomery CountyPolice Confirmed for us there Police Officers maintaining a perimeter. He says if they have to they will go building by building floor by floor, office by office, just to give the all clear that these reports that the report of the single gunshot heard is unconfirmed. Those officers are there. We continue to see more and more Police Officers on the local state and federal levels descend upon this campus. A search for where this call came from. We know this call came in at 10 48 this morning. Someone called 911 reporting that they had heard a gunshot. That is why we see police here. We can see it appears some Police Officers, more people walking out the front doors. A panoramic view of everything going on at this large military campus. We know that at this hour there are hundreds if not thousands of people there to seek treatment. Friends and family visiting them come a sheltering in place as you can see on the right side of your screen, we have got people outside as well. Rebecca cooper, she is live or us on the scene in bethesda. What are you seeing and hearing . Rebecca some uptick in movements. The scene at southwood drive and Rockville Pike. Southwood road and Rockville Pike. That is the gate into the Naval Support activity bethesda. We have sad we have had several Police Officers arrived. They have moved people away they moved all of the traffic that was beingoutside the gate away. They are clearing the area and bring in additional Law Enforcement. The kind of Law Enforcement response you would expect, the same as what we saw at the navy yard when they were trying to establish whether or not there had been shot fired. Law enforcement wearing protective gear. On the other side at south drive, this is the metro stop as well for nih. I have not seen any people come off the metro so i cannot verify it for you but it looks like there is some type of reduced metro activity at nih. You see part police in a decimal and additional Law Enforcement going into gate number two that takes you onto the southwood roadside of the bethesda campus. This is an enormous campus that houses several different federal facilities for the u. S. Department of health and human services, the Naval Department walter reed was consolidated here as well. The gate they are going through is the walter reed side of things. A initial reports were that that is where they may have heard at least one shot fired. Montgomery county police have said they have no confirmation of a shot fired, at least not that they are confirming to us as of now but we are seeing an uptick in activity at the southwood road, gate number two. Thanksgiving so much for that report. Thank you so much for that report. Police officers behind the fence. People in that area are being told to shelter in place. You can see that naval officers in the fatigues behind that gate , not letting traffic in or out. Opening the gate now to let another officer through. It appears only officers are being able to go through and Law Enforcement officials as well. You are seeing on the right side of your screen. You see about 50 feet or so more and more Police Officers as they continue to go through this entire building and investigate where this call came from and what could be going on. Captain paul starks with Montgomery County police told us they will go office by office, building by building on this military campus to see if there is any shooter or gunman or any report of a gunshot that had been fired. All this going on since 10 48 this morning. We have got road closures there. More roads in the area. According to a fire chief spokesperson, he just tweeted out another traffic advisory that more roads in that area around the Walter Reed National military Medical Center may be closed as police expand their search. If you live in this area of bethesda and are headed to the red line to the metro station if you are headed to nih, 355, Rockville Pike, jones bridge road, some of the roads of where you are seeing lanes closed. We know they have just sent out a media alert and that they are setting up a media staging area. It appears they are having reporters on scene go to Rockville Pike and cedar lane as this is investigated by local, state and federal officials. At u. S. Navy, a tweet on that support that report. Security searching buildings come in no confirmation of any incidents. According to the navy, security is searching buildings confirming what Montgomery County fire and rescue as well as Montgomery County police have been telling us as well. As the search continues to try to find the origin of this call and who might have made a call, why they made the call. If they really saw anything. As Jeff Goldberg set, kind of reminiscent of what happened on thursday when police descended upon the navy yard for a similar report. You can see we have some sort of helicopter there as well. Not sure if that is police or fire. It might be maryland state police. It appears they are doing some aerial searches as well for any information or clues that may help them out in the search for this report of a shot fired at walter reed. Within the past 10 or 15 minutes, large groups of employees were being led out of building. We know for the most part people are being sheltered being told to shelter in place. A group of what appears to be employees was led out of the building. We have got several vantage points for you. We have news chopper seven in the big box on your screen. The righthand side are evacuations earlier. We have several pictures from news chopper seven video as well. Two crews on the scene, more headed there. Within the past 30 minutes there are folks being let out of the building from the front, folks sitting in picnic tables. We assume those may be visitors or employees as police go door to door and room by room to investigate this report that came in at 10 48. Do we have Jeff Goldberg standing by with more information on social media . Jeff what we have had is a lot of reports coming in from Law Enforcement. It sort of underscores how much of this is really a fluid situation. We had the u. S. Navy tweeting about 30 minutes ago, personnel responding to unconfirmed acts of shooting reported at walter reed in bethesda. Officers have not confirmed the initial report. You heard captain paul starks on air not too long ago underscoring that there was a report coming in of the sound of a single gunshot. We said some of these statistics but i threpeating to give our viewers some context of the magnitude of what Law Enforcement is dealing with. This campus of 7000 total staff members, 274 total beds and this is a 243 acre facility. You see these pictures from the ground and air of Law Enforcement surrounding the area and thinking about how large this area is. We heard from captain paul sparks paul starks, he was talking about the mindset of what officers are dealing with in this situation, going into this building, not knowing what they are dealing with. This is an unconfirmed report of a shot fired. Presumably they are Walking Around this building and have to approach every turn of every quarter every corner with high alert and intensity as they determine what is going on. You can imagine that in that mindset it is a difficult circumstance for these Law Enforcement. Coming several days after this scare happened at the navy yard. There were concerns over the july 4 weekend. Concerns and warnings about the mystic terror attacks happening in the United States. The mindset domestic terror attacks happening in the United States. The mindset, you can just imagine the tension and the intensity going through their minds. Not to mention shootings that have happened across the country recently. Charleston, south carolina. Situations on the mindset of Law Enforcement while approaching the situation like they are at walter reed. Youre looking from the ground and the sky. Law enforcement surrounding this and on this campus. We did see personnel from inside walter reed walking out with their hands raised as they walked out of the gate. I know Rebecca Cooper was saying gate two seems to be a focus and we see some Law Enforcement movement at the gate. You can see in the bottom right top right of the screen people walking out of walter reed. We do not have any of that information confirmed but 7000 total staff members. We talk about 274 total beds. Walter reed, known as the president s hospital. Your questions of mobility dealing with that many military personnel in the hospital now. So many concerns as Law Enforcement deals with the situation. Rebecca, what can you tell us . Rebecca we are still seeing movement inside gate number two where we see Law Enforcement with their weapons visible. Going alongside the gate, talking to the various security guards positioned at the gate. We have not seen any additional Law Enforcement inside. A few minutes ago we saw several cars come back inside the gate. Right now, it is quiet as we are awaiting to get updates. The employees who had been here and hoping to go inside, they felt like they needed to get inside to work, they said they were not getting communication in terms of what to do. State troopers positioned outside the gate cleared them away from the gate entrance and told cars to leave as well. They have continued to keep this part of Rockville Pike shut down. They are now going throughout the campus and trying to determine what, if anything, they can find. There does not seem to be a sense of panic here. Much more a sense of caution they are taking. Lots of people. Some of the Law Enforcement walking across the ground outside walter reed. No one with any weapons drawn of any type. Right now it seems to be in a cautionary mode. Jeff you talk about that cautionary mode. Are you sensing a different mindset or a different feel than when you got to the scene . Has that taint has that changed in the time youve been there . Rebecca no. Contrary to what we saw at the navy yard there has not been an overall sense of panic. I would not say that was panic at the navy yard but we saw that much more visible presence. We are seeing some vehicles now reentering Rockville Pike so that may give you your answer in terms of what they are doing. This looks like these are metro bus vehicles that may be used as part of the blockade. I do not think Rockville Pike is going to reopen. Throughout the day there has been a sense column calm determination. Just trying to keep people away. Earlier, they did a people to be waiting at the gate of walter reed, thinking they might allow them to even enter at some point. That has changed. People moved away from the gate. Jeff the United States navy confirming its security search is continuing. This is a report of a sound of a gunshot but nothing has been confirmed at this point. U. S. Navy security personnel searching walter reed as they try to determine exactly what happened. Jummy thanks so much for that. We just heard from metro. We know the red line and the station there right near the Medical Center in bethesda still open if you need to get to the metro for any reason. This is affecting traffic as well three and Jamie Sullivan standing by. Jamie the metro may be the best option if you have to get from Friendship Heights toward bethesda because you cannot use 355. I want to focus on the area in bethesda. We are blocked off on 355 in both directions between cedar lane and jones bridge road. As far as alternates, but talk about what you can do to get around. If you take old georgetown road we are in the 20s. He wants to go ahead and use connecticut avenue. You have to use both because 355 is closed. We are hearing they might block off jones bridge road and cedar lane. Still open at this time. If youre heading southbound from rockville, closer toward bethesda, youre only averaging about 8 Miles Per Hour approaching cedar lane which is where police have it blocked off. Northbound from chevy chase to Friendship Heights we are at about six Miles Per Hour. Bumpertobumper traffic approaching bethesda on 355. His block
