At a noose conference last hour, david brown revealed one person in custody is a woman. We are involved in negotiation negotiations with a suspect for the last 45 minutes, hes been exchanging gunfire with us and not being cooperative. Before i came here, i asked for plans to end this standoff. As soon as im done here, ill be presented with those plans. In addition to this second floor garage as we recap the Previous Press release, we have in custody a female who was in the same area of the el centro garage. And we followed a mercedes with two suspects who had camouflage bags who officers end up stopping on traffic in the oak cliff area near polk and 67th. They are in custody and being interviewed. The suspect that we are negotiating with that has exchanged gunfire with us over the last 45 minutes has told our negotiators that the end is coming and hes going to hurt and kill more of us, meaning Law Enforcement. And that there are bombs all over the place in this garage and in downtown. So we are being very careful in our tactics so that we dont injure or put any of our officers in harms way, including the citizens of dallas as we negotiate further. We still dont have a complete Comfort Level that we have all the suspects. So we will continue a very, very rigorous investigation and search of downtown. Well likely be working throughout the Early Morning hours of friday. Until we are satisfied that all suspects have been captured and have the opportunity to be interviewed so that we can fully understand whats motivated this attack on our officers. As i mentioned, one of our officers that was in surgery, that we had hopes to survive pass passed bringing the total count of officers that passed away to four, three Dallas Police officers and one dart officer. Were continuing to ask for the publics prayers and supports of support and encouragement, ive never been more proud of a Police Officers and being a part of this great noble profession seeing the courage, the professionalism, and the grit, staying on scene knowing we are vulnerable. Our downtown is very large with large buildings. Running toward gunfire, to help the injured officers to get them transported to hospital by patrol car, not having the time to wait for ambulance, so many stories of great courage. We continue to fight the good fight to bring this to a conclusion, its a tenuous situation. Ironically, it all began as a peaceful march for justice in the deaths of two black men shot by police in baton rouge, louisiana. Similar demonstrations were happening in seattle, denver, portland, chicago, washington, st. Paul and new york city. Thousands demanding justice for ka steel and sterling. Castille was shot in his car near st. Paul minnesota. Alton sterling was gunned down as two baton rouge officers pinned him to the payment. The Justice Department is now looking into that case. Lets go now to casey steigel in dallas with the latest. Do you have any new information for us . Were talking about this suspect that is still actively exchanging gunfire with Dallas Police, and that is happening in the el centro, which is a Community College here in dallas. Its happening in the el centro parking garage. See the giant green Tall Building . That is the bank of america building here in Downtown Dallas, its the tallest, a lot of people know this, because it makes the dallas skyline, on the other side of the street, on the left side of the street, if you look west that way, the parking garage there is the structure you see that has two yellow lights at the top and then you see all of the lights there off in the distance, just above that string of white lights here on main street in dallas, that is where that suspect is currently holed up at this hour, and has been exchanging gunfire with Dallas Police for more than an hour now, so that is still on going as we speak. As you heard the police chief say, in that press conference, they have been in contact with that suspect. And hes told them that the end is near, and that he has warned them that he is prepared to hurt or kill more Police Officers and that there were bombs scattered across Downtown Dallas. Interestingly when the police chief played that statement, there hasnt been this sense of urgency that we talked about, we discussed this in the last hour because we were getting the feel from officials on the ground that there was no longer a threat to the public. Now this news that there may be potentially explosive devices, we should caution that has been what the suspect has told police. It is entirely possible that it is a bogus story. Think of this, this is an individual who has nothing to lose at this point, police have him backed into a corner if you will, and the Dallas Police chief ended that press conference by saying that they were going to have to leave and make some tough decisions, meaning, at some point theyre not going to play around with this person any more, and a decision is going to have to be made to get in there and neutralize him in some way, the goal to capture this person alive. If hes already continued making threats against more Law Enforcement officials on the ground here tonight, and then threatening the use of explosive devices. Again, this is something who may not have something to lose, and its entirely possible that this coulding a suicide by police sort of situation. Again, this is a bit of speculation mixed in with the facts that are gathering. This is a story that seems to be changing every five minutes or so. The suspects are in custody. And now the police chief saying, there is still an active situation going on between the police and the fourth suspect thats hold up in that parking garage back there. He also talked about three other suspects who are in custody at this hour. Four total, the one still actively engaging officers a woman who was taken into custody, also near that parking garage, and then two males who were seen putting a camouflage bag in a mercedes and speeding away. He was arrested south of downtown here. The situation that is con stan thely changing. If they are they have to take this man seriously. Are you seeing any activity of searching, bomb sniffings dogs. Does it look like people are actively trying to see if any devices are out there right now . No, and thats what strange about it the scene here did not change whatsoever, were talking about only being 2 1 2 blocks from where the shots rang out. The officers were shot just two 1 2 blocks in that direction, past the crime scene tape. Were close, i havent heard any of the gunshots theyre talking about with the exchange of gunfire. We havent heard any controlled detonations, nothing like that, but the bomb squad is on the scene, in addition to the atf, and in fact i want to read this information thats coming in because this is important as it pertains to the federal role in this particular case, this is coming from matthew dean one of our wonderful producers in d. C. , hes saying that the fbi in dallas is involved. The dallas fbi is providing all possible assistance to all Law Enforcement officers. Ill defer to the Police Department to provide details of the ongoing investigation. There was some discussion about the atf. Patricia wright, before i came on the air with you, there was a vehicle parked here, i saw two officers with kevlar, bulletproof vests get in, and their bulletproof vests said atf. Matthew deans reporting here, an atf official confirms that several agents are on the scene here assisting dallas pd in its investigation. Were told that atf canine units currently scouring the scene for shell casings, which investigators would hope would point back to registered firearms that may belong to the individual or individuals behind this incident. Fox has been told there have not been any firearms recovered from the scene, there are lots and lots of shell casings. We talk about the scene. This is a very elaborate crime scene in Downtown Dallas, and in that press conference, the police chief was talking about how theyre just trying to assess how large it is. Because i can tell you the Police Perimeter goes for blocks in directions all around us in a big square, and so the mayor of dallas, mayor rawlings was talking about how theyre trying to ascertain how big of a crime scene were talking about here, because thousands of people commute into Downtown Dallas every day, its a major u. S. City, lots of businesses are down here, lots of people commute into the city for work. People may have the day off tomorrow because large portions of Downtown Dallas will be sealed off. A lot of people may not be able to get to work tomorrow as investigators try to peace together the evidence thats scattered downtown. Not knowing if any of these devices exist or are planted anywhere. Chief brown said he was not completely comfortable, that they even had all of the suspects, so i can imagine theyre not going to want to let a lot of people into that city in the morning to compound these things. Exactly, we had been under the impression this was coming to an end and it was under control, then the police chief rattled through the suspects he had in custody. He followed that up with saying, theyre not entirely comfortable, that is all of the suspects theyre dealing with. Weve been talking about this over and over tonight. This was a peaceful protest, nearing the very end this took a lot of people by surprise. There is a lot of processing that has to go on. Youre talking about multiple police agencies. Dallas pd. Metroplex Police Officers responded. Clearly a lot of moving parts here, a lot to consider, but again, the headline right now at this hour, here in Downtown Dallas, police say they have one of the suspects they believe who is responsible for this attack on police. Tonight in dallas, they are exchanging gunfire with that individual. And they have been for more than an hour in the parking garage just two and a half, three blocks up the road from where im standing, police could be making a decision soon as to whether or not they want to move in. Potentially neutralize this suspect. The goal here, of course, to try to take this person alive so they can be brought to justice, pa trivia. I know you got there, pretty quickly, you were stuck in traffic, you got there relatively quickly, when this is all taking place, there were hundreds and hundreds of people at this peaceful protest, and now behind you, im not seeing many people, i know youre only two or three blocks where this took place, we had heard someone earlier stating they were getting people on buses to get them out of the area. Whats that balancing act of trying to get these people to safety and then not letting some of those possible suspects slip through the cracks, not knowing whether we have them all. Its a pretty arduous task as you can imagine, you had hundreds of people that filled the streets here for the protests, and people couldnt get to their cars. It was really a scene of pandemonium as you can imagine. We talked to a flub of eyewitnesss, when we first got on the scene, who said that people were literally running in every different direction. No one knew where these gunshots were coming from. And the videos we have seen emerging from people posting to social media tonight. You hear rapid succession gunfire, like a semiautomatic weapon, there are minutes that go by where it is silent, and there is no more gunfire, and then another round can be heard. So this lasted for several minutes on and off, on and off, and so you had people running every which way, absolute chaos, people ducking for cover, i talks to a guy that said he was hiding behind a pillar of a building, a concrete pillar, because again, its dark. You dont really know where these shots are coming from, so suddenly people are running in all directions. So now you have a lot of people who are trapped, essentially, because they cant get out, and thats why they were trying to bring in the buses, to get these people to a point where they can get out of the perimeter, as far as the crowd where im specifically standing, not far from the crime scene, not many people at all, in fact, i would say only about 20 or so people gathered over in that location. And frankly, those might be some people that spilled out of the restaurant here. Its a thursday night, people were down here having drinks and dinner, and so some of the people gathered in the corner may have been patrons of the restaurant who spilled out on to the sidewalk and had a birds eye view and an up close look at all of the action that went down here. Earlier this evening. Casey stegall, live from dallas, thank you so much. We will continue to check back in with you throughout the morning for updates. Now we go to our washington, d. C. , bureau and kelly wright for more information. We are getting word that the atf, the fbi is getting involved, providing all assistance to dallas. And we have ted williams standing by whos going to be talking to us. Hes a criminal defense attorney, also contributor for fox news, particularly with the Greta Van Susteren show. Can you hear me . Youve been following the updates tonight, youve seen what took place in dallas. It got really deadly and really ugly as at least what we know right now, several gunmen perched on top of buildings, try angulating their shots, using a high velocity type of weapon and firing upon Police Officers, targeting them. 11 of them shot down, four of them are now deceased. Four three Dallas Police officers, and one dart officer. Tell me what you think is unfolding now, and how this country moves forward after dallas has experienced such a crushing blow to its Police Department, yet they are still on the streets trying to protect the public and trying to serve. Yeah, kelly, its what were looking at here unfortunately, is a war zone. We have what i believe is an orchestrated assassination of Police Officers in dallas, texas. I think you are looking at investigations that is going to have to take months to try to find out what took place here tonight. One of the greatest concerns is, that this kind of assassination. Assassination attempts, could very well peel out to other parts of the country, and other jurisdictions, im sure everyone is on a high state of alert. There is absolutely no way that this was not orchestrated and planned by i dont know, but some group. Now, what will be very beneficial in the daylight to Law Enforcement would be the various videos, cameras, that are located on various buildings down there in dallas texas. And im sure that Law Enforcement is now gathering as much video as they possibly can. As you know, kelly, theres one individual who the exchange of gunfire, it is alleged, in a garage, theyre trying definitely to take that person alive they need to get as much intelligence as they possibly can from that person and others. There have been threats that there are bombs, that these individuals have placed throughout the downtown area of dallas. That may or may not be true. But out of an abundance of caution, Law Enforcement cannot take any chances. My assumption is, that they are going to announce pretty soon that if individuals in the dallas area can help, that they stay home, and not try to come downtown, because again, without being redundant, were looking at a war zone in dallas texas. Ted, you know, this entire matter, when you look at what took place this week, with the police shoots, you know, that took place in pasadena. Someone was talking in my ear. You look at what took place in minnesota, and baton rouge. And some of the other shootings, Police Shootings of africanamericans, all of this obviously building up the anger, but then you have this racial tension thats going on in america. You have the division thats going on between conservative, liberal, democrats and republicans, on and on. Division after division after division. We see the lack of people coming together to try to bring about some understanding between police and the africanamerican community. And whatever happened here tonight, it started off peaceful. It started off very peaceful. The undercurrent of all this, is the sieging anger must have contributed to this in some way, or just sheer hatred of Law Enforcement, looking at it from a criminal defense perspective. What do you think is going on in the minds of these criminals who carried out this heinous attack on Law Enforcement . Kelly, i believe that whatever we are now seeing taking place in dallas, texas, has been well planned and thought out, and i think that youve got a group or groups, who have been studying and waiting for this kind of an opportunity to occur. Weve had unfortunately, shootings in this country throughout its history and most recently, weve had quite a few shootings of young black men by Police Officers. But what we have here is some orchestrated group who decided to take advantage of that situation in order to kill Law Enforcement officers in the manner in which theyve acted here tonight. We have to be very careful when we tried to look at the direct nexus between what is going on in baton rouge, louisiana, and what took place in minnesota, and what is happening here tonight. This may be a group who took advantage of that kind of racial tension to carry out their own ugly terrorist acts. When we use the word terrorist, we need to be very careful. We i am talking about home grown terrorists. I think in the coming days were going to find out that this was an orchestrated conspiracy to kill Law Enforcement, to create havoc in dallas, texas, and again, i am sure Law Enforcement throughout this country are on a heightened state of alert, because theres s
