Joint statement. It was scheduled for about 15 minutes ago. They are about a third of a block away from here. We hope to clarify what caused this. There is a standing down and some military personnel are leaving at this hour. You might say that media outnumbers the amount of Emergency Personnel on the scene. Again, hopefully we will be hearing from an admiral who is chief of naval installations wells the mayor and some other local Public Safety officials. Tell us what it was that led to this tense situation here earlier this morning which, indeed, now is sort of winding down. Derrick ward, live outside the navy yard. This is video from a bit earlier today. The mayor we saw in that live picture along with the police chief, cathy lanier and some folks from both the fbi and the United States navy you see here gathered just a few maybe half a block away from where he is set up. At this point, we would imagine they are sort of matching up their information we see the mayor there in the pink coat as well as who we believe to be vice admiral dixon smith, who is in charge of all Navy Installations along the with mayors chief executive officer off to her one side and the police chief walking up behind who we believe is the admiral here to brief us on what exactly led to the lockdown that we saw at the navy yard for a few moments this morning. What have they learned from the person that phoned in the 911 call and reported a threat and hearing. Lets go straight to the news right now with the d. C. Mayor. I am joined by admiral dixon smith, chief of police, kathy loo near lanier. We are here to give you a report on this mornings incident at the Washington Navy yard. We want to report that the police were called and asked for assistance by officials at the navy yard. Weunder we understand an employee atd the navy yard reported that she may have heard gunshots. The Police Official sent out the call to Law Enforcement in the area. Our police responded. Our police went in to the facility with the assistance of our federal partner. At this time, there is no evidence of gunshots. There is no evidence of a shooter and there is no evidence of any victims today. We look forward to finding out that all of our partners responded as they should have the chief of police will convene an afteraction meeting shortly after the incident is cleared to see how everybody responded. Im very proud of all the of officials that answered the call. We know there have been a lot of Lessons Learned from previous incidents and fatalities here at the navy yard. We have found there has been a clear, coordinated and convincing response to this scene. We are grateful at this point that we have found no shooter, evidence of shooting or any victim. I want to turn it over now to the admiral so that the admiral can describe how Navy Officials responded in the current investigation in the center. Then, we will hear from the chief of the metropolitan Police Department cathy lanier. Thank you, mayor. Im vice admiral dixon smith, commander of Navy Installations command. I would like to thank the mayor, d. C. Metro all of our First Responders from the federal and metro area. The response was outstanding this morning and very much appreciated. As the mayor said we received a report of an active shooter this morning at 07 29. We responded and called in assistance from metro d. C. As the major stated, no signs of a shooter no shootings and no injuries. Navy yard remains in lockdown and building 197 we are finishing up the final walk through right now checking and opening up all of our secured spaces. We expect that to be done within 20 minutes. Assuming we find nothing, we will open up the navy yard again. For the folks evacuated out of 197 the humphries building, based upon their location, they went outside of the navy yard or over to our conference center. Based upon the events of a couple of years ago, we have counselors and chaplains with them providing the support they may need or desire. In closing, i would like to thank the mayor and the police chief and all the First Responders for your Quick Response this morning. We have learned a lot over the last chem of years. We have exercised har. We are going to review this to see what went right and what we can continue to improve upon to improve our procedures in the future. Thank you very much. Just so i can give you a quick rundown. First the call was placed from inside of a building, around 7 29. It went to the internal call center inside of the navy yard. That call was received for possible sound of gunshots was then immediately taken by the Naval District of Washington Police and broadcast to the metropolitan Police Department citywide channel and request for the metropolitan police and other Law Enforcement partners to assist with the potential active shooter at the Washington Navy yard. The metropolitan Police Department along with the united park police, metro transit police, ncis, United States martials atf and others Capitol Police all respond today that request for Law Enforcement assistance. Many of the things we talked about in our after action to the Washington Naval yard response a couple of years ago went very, very smoothly. Officers were immediately able to access the gates and get in. We were having Radio Communications both in my command center and in the field immediately from Naval District of Washington Police officers inside of the nafse command building. Within 20 minutes of the first call i was sitting in unified command with admiral halartes police chief and representatives from the fbi, ncis and other federal Law Enforcement agencies. In just about the same amount of time metropolitan Police Officers and fbi were able to get into and take control of the command booth and access everything we needed in terms of cameras and stuff inside of the building. So having spent a lot of time doing the after action from the first incident at the navy yard, it appears that all the things we tried to correct and make go better from the last incident went very, very well. A very smooth, well coordinated response here and very happy that there is that this turns out to be a great exercise for us. Nobody is hurt. No evidence of any shots fired. At this point we will take any questions you have if we can answer them. The question is how do we track the increased threats for Independence Day. All evidence was there was no criminal acts no shots fired and no one was hurt. We dont believe it was a malicious hoax or incident like that i dont think it has any relative play on that threat level. We take every event very high and our posture remains high for all events and it will continue for the fourth. I meant by my question. Is it possible that someone just heard construction noise, perhaps . Obviously anything is possible. I think that we tell people see something, say something. You dont know whats going on. Dont take things for granted. Make that call. Regardless of what it is, an employee thought they heard something of concern. They made a call. Thats what we tell people to do. Chief, are you saying mtv units were the first to come in . Could someone have been climbing a fence minutes before the gun shots . Are you investigating that . I am aware of that. We have pulled all video. We have no concerns about it right now, none. Admiral, can you talk about the active Shooter Drill, what it is that you practice on a routine basis and how it works at this time . Sure. All of our commands practice active Shooter Drills. We simulate an active Shooter Drill in the building and we train with our employees on how to respond. The first thing is to get out. If you cant, you barricade yourself and if you have to then you fight. We go through that and exercise that and do it on a routine basis so our employees know what to do. There is no doubt in my mind that that made a difference in the actions that the employees and the nafse did in the hum humphries building. What else can you tell us about the person that called in the report about shots fired . Is there any concern they did it on purpose . Is there any possibility they have connection to a terror group . We have interviewed the person. There are no concerns whatsoever. They did exactly what we asked the public to do. Call the police if you have a concern. Naval district of Washington Police were inside of the building when they made the call to us. With he followed them into the building, yes. Reporter chief, where was she when she heard this . She was inside of an Office Inside the command building. Reporter looking back at the size of this response how many people, how quick, was any of that colored by the announcement of increased concern about terrorism on Independence Day . I think the response we saw here today is exactly like the response we saw here when we had the active shooter here in the last incidence. We take every call seriously. When we heard a call go out for a potential active shooter we brought the resources that needed to be here. I think it has nothing to do with the increased threat level. Thats what we do every day here. Reporter can you speak to the larger question about the july fourth weekend and your concerns about Security Threat in the Nations Capital . I think we operate in washington, d. C. , there is an elevated threat level at all times. We never lower it in terms of our posture. We are aware of the discussion and chatter is around the fourth of july lieie vents. We change our tactics but never lower our posture. We always maintain a very high postier. We have a full deployment for every fourth of july. Reporter what would you say to people that are worried on edge coming to the fourth of july with events like this and previous events as well . What do you tell people that are on edge . This event those you have a city thats very wellprepared, a city that has a lot of local, federal, Law Enforcement assets that are very well coordinated. We Work Together every day. It is not only what you see. It is what you dont see. We do that behind the scenes as well. People should feel very comfortable that this type of response does happen and unfortunately happens when there is no loss of life or real incident. Chief,why are you convinced this wasnt a hoax . Why are you persuaded this was a misunderstanding . Because we have spoken to the person that made the call. She heard a noise and made the call. We have no concerns this was a hoax whatsoever. Reporter after the initial response, could you tell us what happened there . What often happens with a response of this nature, a lot of Police Activity going on in the neighborhood. Peoples sense of alertness is heightened. When they see Different Things going on, they will call, which, again, we ask people to call. We started getting additional calls about people on roofs. A lot of what we are getting were people calling in what they thought was Police Response. Most of the officers that responded here today were in uniform. Some were not. Those officers not in uniform, we did get additional calls about persons showing up that may be suspicion. They turned out to be Law Enforcement. Reporter is that person that made the call here on the question is was the person who made the 911 call today a person who was here during the original navy yard incident . I dont want to answer that question. I would respect the privacy of the person that works here and i would rather not answer. You are going to have to repeat it. Im sorry. Information was coming in constantly as we were arriving on the scene. We were in the command center very quickly and able to listen to the call and listen to the radio transmission. Information came in constantly as we were here. Once we started going through the building and interviewing employees, we took all the employees from the building to a separate location and began interviewing them. The more and more and more employees that we interviewed, the more comfortable we felt that we were really going in to just secure this building to make sure. We dont take anything for granted. Every inch of that building has been searcheded and is being searched the second time. Let me just say, we want to thank everybody for being here and taking this information. I think what we see is, again, we had a clear, convincing response to this scene. What weve also learned is that things we could have improved upon that are we have learned over the last couple of years we have done exactly that. I think the coordination between our Police Department and our federal partners has been so well executed in this event. When we talk to our residents and visitors that want to celebrate Independence Day in the district of colombia. It should be very clear to everybody that we take clear and Credible Threats or calls from our citizens and employees very very seriously. It should also be clear that the Law Enforcement apparatus of this city, which is not only our 4,000 officers but a significant number of federal partners wiaccordingly. We are looking forward not only to the events on the National Mall celebrating the independence of our nation. We will also stand up a significant number of events in our neighborhoods. So the 660,000 people of washington are also going to be celebrating Independence Day in their neighborhood. Thank you, everybody. This conference wrapping up outside the navy yard where we have learned this morning there was no incident essentially at the navy yard. No shots fired. No shooter. No victim. This was an employee there at the Naval Sea Systems Command building who heard the call to see something say something. She did exactly what she was supposed to do and called 911 when she thought she heard gunshots. There was some chatter where people thought this was a malicious intent or a hoax. She said after speaking with this individual and interviewing other people, that was not the case. She also went on to say that the communication process was very smooth between the agencies. Within 20 minutes of getting this call, she was already sitting down with Navy Officials. She went on to say how happy she is that this turned out to be a very, very good exercise for them and everybody involved. The vice admiral there, smith noting that the navy yard is still under a lockdown of sorts. The term he used is that they are still doing a walkthrough. The humphries building. To make sure they have looked in every secure part of the building so there is no issue you of concern. The next piece is they are going to review what they did right and what they can improve on. Melissa has been tracking street closures. Just got off the phone with d. C. Police. They are saying m Street Southeast is still blocked at fourth Street Southeast.
