Whoever placed these bombs, we will find and they will be brought to justice. Period. This is freedom, this is democracy. And were not going to allow them to take that from us. As we await the News Conference, we have a number of reports covering the newest angles on this story. That News Conference set to begin shortly. Pete williams is in washington on the investigation. Hallie jackson and Kristin Welker have reaction from the president ial candidates. What are we expected to hear at the briefing . Reporter were expecting to hear more details about those explosive devices. We did learn new information from the governor who about an hour ago he walked the scene and he said that both of the buildings on both sides of the explosion severe damage. He said based on the damage that he saw, he was surprised nobody was more severely injured. As you recall, 29 people injured. He says all of the people have been released from the hospital. He also tells us that both of the devices the one that went off as well as the one that did not detonate which was the Pressure Cooker, they were similar in design and will be processed. He also said as well, the explosive device that went off yesterday morning in seaside park, an hour and a half outside of the city, that will be sent to see if theres any link. There is no further threat here in new york city. But they are putting out 1,000 extra new York State Police officers as well as the national guard. They will be at airports, buses, subway stations. Lets listen in to a little bit more of what the governor had to say. As governor of new york, this is my Worst Nightmare. Right . My Worst Nightmare is the phone rings late at night and theres some terrorist attack, emergency, flood, hurricane, act of mother nature, that puts lives in peril. So this is the nightmare scenario. When you see the damage, i think we were fortunate that there were no fatalities. And when you see the site itself, it just confirms that. This was a significant amount of damage. Reporter something that could turn out to be a key piece of evidence, there is video of a man putting something in that trash dumpster before the explosion. They are trying to figure out if this man has any connection, who he is and what he was doing in the area before the explosion. Thank you so much. We await the News Conference coming our way any minute now. Lets go to nbc news justice correspondent Pete Williams in washington for us. A good day to you. What are your sources telling you about the investigation . Reporter the key thing here will be inspecting all these bomb parts. The device in new jersey didnt go off completely. Its largely intact. The device in new york on 27th street is completely intact. Then, of course, you have pieces from what was found on 23rd street in new york, the one that did go off. This is the intact one with the hole drilled in the top, some kind of timer. This sort of method of approach is very similar to what has been out there on the internet for the last six years on how to build a device in a Pressure Cooker. It was followed largely by the Boston Marathon bombers. Its not distinctive. What the fbi at quantico will look at as they compare all the explosive devices and the pieces from new york is, are there commonalities in the way the things were constructed in precisely how the holes were drilled, how the wires were connected, what kinds of timers, what kinds of cell phones were used, what was the explosive material inside them, do they have that in common . As opposed to the one in new jersey which was pipe bombs. Three pipe bombs wrapped together. One of which went off. It may not have gone off completely. Also following similar instructions that are on the internet. Thats one key thing that the investigators are following. We still arent 100 positive by the way, alex, because we have still conflicting information from the authorities whether the device in new york on the 23rd street location that did blow up with such tremendous force, whether it was actually played in the dumpster or near to it. If its in the dumpster, well, that suggests sort of similar approach to new jersey. The one in new jersey was in a plastic garbage can along the route. These are all questions that they are going to be looking at. Then, of course the additional factor that you have all this Surveillance Video from new york. So you can look at, for example, the video of somebody throwing something in the dumpster and then go around to surveillance cameras that are further away from the site. That person approached from somewhere. Did the cameras pick that person up from somewhere else . How far out can that be traced to give them more information about who that person was . Whether thats somebody dumping garbage into the dumpster or placed the bomb. Let me ask you this. We are looking at video at different points that we have gotten access to, this Surveillance Video. How much more is there out there that you believe police may have their hands on . How much more can they learn from that . Reporter well, i dont know how much more they have. Undoubt undoubtedly, its more than we are able to show. What we are showing is what the stores and businesses like this gym, for example, have given us directly. But they will go to all the surveillance cameras. There are so many of them in new york city. This was one of the important things in investigating Boston Marathon bombing. Its that piecing together of movements that will be important. They will work out in circles away from the scene on 23rd street and on 27th street, too. They will want to see who placed that, was that picked up by a camera. Can you look at nearby cameras and trace the movements of that person . As they approach the scene. Thats the advantage of the video, not just what you find at the scene itself, but can you now trace that persons movements using other cameras . Thats a big part of what theyre doing now. Okay. Pete williams in washington with the latest. Thank you so much for that. Let me bring inormer assistant special agent in charge of the Fbi Joint Terrorism Task force john berelli. A couple of things i want to go over. The governor came and said that he does not believe this was linked to International Terrorism. But its still very early on in this investigation. Can anything really be ruled out at this point . Would he be saying that because theres no someone taking responsibility or note or anything . I think the fact that there is no responsibility claimed yet is why people are saying this isnt an International Terrorism incident like isisinspired order al qaeda thing. I think its clear that this is an act of terrorism. By judicial statute, you have a weapon of mass destruction that was used, this bomb. So that falls into terrorism. What the inspiration, domestic, International Terrorism, whatever yet to be determined. The authorities are acting under the umbrella this is an act of terrorism. Here we are 16 hours later since the first incident. Where is the investigation at this stage . Multiple tracks. You have you have a lot of analysis of video being done. Can they get an image of a person or persons responsible for putting these devices in place . Then youve got the collected evidence, the unexplode and remnants of the exploded device that are at quantico. They will be looking for things like fingerprints, hair and fiber. They will look at the components. Was this sophisticated or amateur device . Is there data that can be exploited to say what cell towers . Did it start in new york . Did it come from new jersey . Theres a lot of information out there. Its going to take time to put it together. As of right now, theres a good amount of leads for investigators to follow. You mentioned new jersey. Thats something that happened in seaside park previously yesterday earlier in the day where an explosion went off. Fortunately, nobody was injured because it didnt go off when people would have been running by in this 5k run. Are there things about that that lead you instinctively to believe its connected or not connected . As of now we dont know all the facts. My gut tells me, probably not connected. The reason is, you have just such different devices. You had the pipe bombs that were wrapped together versus this Pressure Cooker. Generally when a person is a bomb maker, they usually have a signature. They figure out the way they like to construct a device and follow that same pattern every time. Investigators at the fbi have been following for years patterns of bomb makers. There are people that practice and get their fingers blown off. Now, its not to say that the incidents arent connected. But kind of instinctively, i would say, probably not at this point. Anything in terms of listening to networks, talking about chatter, possible attacks in the area . We have the president , he will be here. Its the u. N. General assembly. We have foreign dignitaries here in new york city. Theres a lot of things to consider right now. Of course, sl media investigators and the intelligence community, they will look at chatter or anybody online with a claim of responsibility. They will look, does somebody Say Something online that leads investigators to believe that they have more knowledge than whats been publically released . You have the u. N. Right now, all the delegations arriving. Was this just something to divert resources from the west side of manhattan to the east side where all the u. N. People are . Was it designed to look at the Police Response and then take notes and then the next one maybe be more lethal . Theres so many things to consider. Who knows right now . Im going to ask you to stay with me in the studio. We are awaiting this News Conference. This is going to be from mayor bill de blasio and the newly coronated, if you will, nypd commissioner, james oneill. Talk about one way to get started on the job. He took over friday when bill bratton resigned. Or retired, we should say. Anyway, we are going to stay on this and take a short break here and bring you back with the News Conference on the other side. Stay with us. Eyelove is making something unexpected.

Sg thank you very much, commissioner. You are going to hear after i give some opening comments, you are going to hear from commissioner oneill in detail and then commissioner nygro and bill sweeney, assistance director of the fbi. I want to thank our federal partners who have been with us from the beginning of this incident. Were working very, very closely with the fbi to determine exactly what happened here. I was in the effected area this morning talking to residents, Governor Cuomo and i spoke to a number of people who live and work in that area. I want to say at the outset, i want to commend my fellow new yorkers who deal with challenges with incredible resiliency who are strong, who are focused on going about their everyday business, who are not intimidated by anything. Thats something were very proud of here in the city. I talked to a lot of people, including folks in their homes or businesses the moment the explosion occurred last night. They uniformly said, it worried them for sure. But they also said it was not going to change anything they were doing today. I saw people out there going about their business as usual. I also saw an extraordinary response by the nypd, fdny, office of emergency management. Folks said how reassured they were by the speedy response last night, by the continued Police Presence. They understand theres an Ongoing Investigation that will take some time. They understand there will be some disruption in the immediate community. But by and large, people are getting back to business as usual. We heard a good report on the mta. No damage there. That will be up and running soon at that subway stop. The attitude people took was one of gratitude for our First Responders and a sense that they were safe now with the kind of presence that was around them at this point. Now, this was a very serious incident. Its going to take a lot of careful investigation to get to the facts and get to the truth. One of the things were going to say to you today is were going to be very careful and patient to get to the full truth here. We are not going to jump to conclusions. Were not going to offer you easy answers. Were going to make sure we have all the facts. We know there was a bombing. That much we do know. We know it was a very serious incident. But we have a lot more work to do to be able to say what kind of motivation was behind this, was it a political motivation, personaltiva moon . What was it . We do not know that yet. That work must go on. Were going to give you regular updates as we get more information. In terms of those who are affected by this incident, 29 individuals were injured. All have been released from the hospital now. You will hear more from commissioner nygro about the response by the fdny and the status of those individuals. We obviously, our thoughts and prayers are with all of them for a full recovery. Im very pleased to say they are all out of the hospital. For all new yorkers, a central message we want to give today is, be vigilant. Be vigilant at this point in time. Not just because of this incident. Be vigilant because were going into u. N. General assembly week. Be vigilant because the police need your help. And if you see anything that might be pertinent to this case, we need you to call it in. And you should know, you will see a very substantial nypd presence this week. Bigger than ever. We would normally have an expanded presence for the United Nations general assembly. You will see a stronger presence now. New yorkers always tell me how reassured they are by seeing our officers, including our newer units such as the Critical Response command and the Strategic Response group, seeing them out in force and seeing them at the scene of obviously key public locations around the United Nations, around times square, a lot of other places, well armed, well trained. This new unit and the capacity that it has are crucial in keeping this city safe. You will see a lot of them this week. That capacity that we have built and commissioner oneill was a crucial part that was effort, the capacity we built over the last two years in response to events we have seen over the world, gives us the strongest antiterror capacity of any city. It will be fully in use this week. Now, we know from everything we have seen so far that this was an intentional act. I want to reaffirm what i said last night. Again, we do not know the motivation. We do not know the nature of it. Thats what we have to do more work on. The investigatory agencies continue to look to see if there is any specific connection to the incident in new jersey. At this point, we do not have any specific evidence of a connection. But that will continue to be considered. So were not taking any options off the table. I want to be very clear about that. All possible theories of whats happened here and how it connected will be looked at. We have no specific evidence at this point in time. Again, we are going to urge all new yorkers to be patient as we get down to the bottom of what happened here. We want to be accurate. I think the most important thing is to give people a clear and accurate picture of what happened and obviously to bring to justice whoever was involved in this incident much the ypd is using its full capacity to find anyone who was involved and bring them to justice. I want to affirm again, if you have any information that might link to this incident, video, photos, eyewitns accounts, overheard conversations, anything, please call the nypd. 1800577tips. 1800577tips. New yorkers as always are not intimidated. Its part of who we are. We will go about our business. We will help our police to do the jobs they do and they are the finest in the world. In spanish [ speaking in spanish ] with that, i turn back to commissioner oneill. Thank you, mr. Mayor. I will give you an update on last nights incident and whats going on right now. We have two separate crime scenes. Keep in mind, were in the middle of a very complex postblast investigation. There are a number of agencies involved. Of course, the nypd, fbi, atf and the state police. There are many agencies involved in this complex investigation. Were still gathering evidence at 23rd street and we did find some components indicative of an ied. We are we moved a device from 27th street up to rodmans neck last night. The bomb squad is in the process of working on that device right now. Of course, they are taking their time. They want to make sure that we use as much time as necessary to make that determination what that device is consists. We have recovered video from both screens. We are canvassing witnesses and video. We are looking to speak to anyone i
