Cooker just four blocks from the explosion site that did not detonate. As the investigation continues, in minnesota, an isis linked News Agency Says man who stabbed nine people was a soldier in the Islamic State. That man is dead, shot by an off Duty Police Officer. Much more on that this hour. We begin in new york where city and state officials are promising that new york city will be back to quote, business as usual tomorrow as the workweek begins. Also as Global Leaders descend on the city. Some streets blocked off while officials continue to comb the area for clues. I understand theres some activity behind you. What do you see . Reporter a little bit of activi activity. You might be able to see the two officers from the nypd investigators. They are looking at a subaru there to the left. Theres one squad car with police officers. They seem to be keeping an eye on it. Unclear what that car is. We know that it does have new jersey plates. Investigators are looking for a possible connection between that device that detonated in new jersey and the one that detonated here yesterday evening at 8 30 on west 23rd street. The investigation very much in full swing. Evidence being collected. Investigators are looking for any possible clue, a wire, a detonator, bomb residue. Anything that can give them a better picture of what that device was made of that exploded. A key piece of evidence will be the dumpster because the dumpster would have absorbed a lot of impact of the blast. Somebody who said earlier said if they find a bomb, one thing they due is throw it into a dumpster because they want to minimize injuries. We know they are looking at the device that was on west 27th street. That is more critical because it was intact. There could be some sort of dna, a finger print, hair. They also know how the bomb and the device was made because there was a cell phone atamped to it. Someone i spoke to said cell phone is a bit troubling because it suggests that whoever made it did not have to be close to it in order for it to detonate. They could place a call and had it go off. Its different to the boston morton bombing where the two in that particular case were really in the vicinity of that explosive device. All of that right now under review of the cell phone. Critical in terms of what the investigation suggests. Theyre still asking anyone in the area if they have any video, overheard any conversati conversation, anything at all to call the tips number to help police get to the bottom of this. They dont know the motive and their not naming anyone. Lets bring in our panel. The fbi is calling this the three bombs in new york similar. Lets talk to ed davis. He was the commissioner back in 2013 during the Boston Marathon bombing. Also with me cnn Law Enforcement analyst. Thank you all for being here. Just to begin with you, lets compare your reaction in the first hours after the horrific bombing in boston. They said it was intentional but did not licnk it to terrorism. What would make think not make the jump . I was in new york on friday night with the commissioner and i can tell you they are doing the same thing wes did following the marathon. They are looking ing at the evi. There is a hesitance to use the terrorism word. Theres a lot of political reasons for that. I think in this particular case there are some differences that might differentiate between what we were seeing here in new york and what happened in the marathon. I had two powerf fuful blasts. I had a number of victims, over 200 victims. I had shrapnel on the ground. I had these going off in close proximity in time and space. We believe there had to be two people. There was a lot of information that we had that made it really straightforward. I think mostly, i sat down with rick who was the special agent in charge of the fbi and we all had the same feeling. I think at that point even governor patrick said this should go to the fbi very quickly. Little bit of a different situation in new york but clearly its a difficult decision to make. They put these pipe bombs in a garbage can. In new jersey only one detonated and they put this in a dumpster in new york. Why . Probably to thwart the efforts of if you see something, say something. Whos going to look in the dumpster or inside a trash can or plastic garbage bag that may be inside a bigger container. If you have a loose container on the sidewalk its going to be more suspicious. Its more likely to have somebody call the police and report it compared to debris thats thrown into a dumpster or a normal trash can. Our viewers are looking at live pictures out of new york city tonight just almost 24 hours after the bomb exploded on west 23rd. They have police tape around this vehicle. We dont know why. They are scouring the area for any clues. There could be three separate acts in one day. Here is some things positive. Is it possible that the exemployes yesterday morning was call to action for any sympathizers . Very well could be. I dont want to close off any possibility. I would say the new jersey bombings were pretty unsuccessful. They werent even leading the news for most of yesterday. In terms of being call to action, its a pretty subtle or unsuccessful one. Im definitely much for saying that the ties between new york and new jersey might be more likely. Lets be clear here, those devices are pretty rudimentary. The information is out there on the web for any group to take. One of the reasons why ive been sort of more comfortable waiting on the terrorism word, understanding that theres terror out there is because the information right now is cutting in a lot of different directions. Theres pieces that arent making a lot of sense to us that know the cases. The investigators should continue with the open investigation until they can narrow it down. Was it for you and your team and the fbi in boston was the most helpful to identifying the sarnaev brothers where the bombs went off in boston and the bomb went off here in new york city last night. Obviously, a lot of cameras in the area. What was the single most helpful thing in identifying the brothers . The forensic evidence is important. You have to find out what devices were used. The biggest break came from video. Its the most important piece. This digital evidence that we can access now is the single most important piece of evidence. I spoke to the Police Commissioner in london after the bombings and he told me he would not have solved the case if it wasnt for video. New york is set up in a familiar fashion as far as city owned video thats available on the street. They just have to process that. It takes a long time. There are no systems available to do it automatically. It takes days and sometimes weeks before they can get to the right place. Youre already seeing some movement in that area. Thats beginnigoing to be the s most important thing. What do you make of the fact that minnesota has had someone claim responsibility for the inspiration of the attack there. That being isis. What do you make of the fact that in new jersey and here in new york almost 24 hours later no claim of responsibility . Isis doesnt always come out immediately even in an isis inspired attack. Part of the reason might be the way this was initially reported especially when they said the act was intentional but they werent going to link it to terrorism that isis may have been a little cautious thinking this could be a psychopath who learned how to make a bomb and decided to detonate it and harm people and get attention and isnt really a true soldier of the Islamic State unlike the situation in ming yap lis where there was more information to indicate it probably was somebody inspired by isis. Stay with me because i want to take us back to debra on the ground tonight. You have Police Vehicle in front of this subaru that they are looking at. Do we know why . We dont. It looks like theres a forensic investigator from the nypd. Shes taking photographs. It looks like right now she is scraping or trying to gather evidence from the vehicle. They just brought in that large vehicle just moments ago. This car is of particular interest to them. Its also got new jersey plates on it. Whether they have determined theres a connection between this new jersey car and perhaps the innocent that happened here on west 23rd street and the incident that happened out in new jersey, we dont know. We can also see a couple of fire trucks behind us. We did check with the Fire Department to see if it was connected to the discovery of this vehicle. Were told they have fire trucks on scene. Just set up for us where you are. If we can see the relation of where you are to that vehicle. Whats interesting to me is theyre not clearing you out. We saw the 27th street location they pushed Richard Quest very quick verbally saying move out of way. Move out of way. We know thats because the Pressure Cooker bomb was there. Youre a quarter of a block away and theyre not doing that. Theyre not doing that at all. We were quite close to the car. One thing i learn frd the Boston Marathon is if you can see the bomb, the bomb can see you. The investigators that are working that car and trying to gather evidence are not wearing any protective gear. Whatever they have done suggests that they do not need to be wearing some sort of protective gear. They are bringing in that second truck. We cant quite tell theyre opening the back. We cant tell what theyre doing. That car is of definite interest, poppy. Thank you. Stay with me. What do you make of this . A lot of details we dont know. Deb made an important point. They are letting her stay close to this and theyre not wearing any protective gear, the investigators. Frankly, any car with a new jersey plate on it in the proximity of this incident in light of what happened in new jersey earlier in the day would be cause for this type of look. They would be evacuating the area as immediate first protocol. I would say this is a standard checking of the vehicle and if they discover something or something is awry there, it will be an immediate evacuation of that whole area. Julia, to you. When we look at the totality of what is being called now three possible terror attacks on u. S. Soil in a single day yesterday. We look specifically at the minnesota attack that this isis connected news agency claimi ii responsibility for calling this person a soldier, you called this a third wave of terrorism. Isis justified. Im talking about the minnesota attack. What do you mean by that . Theres a new kind of isis attack. Isis inspired is what we see in the United States. Someone getting radicalized and doing encryption or some kind of communication with isis. They say do this or be violent and harm americans. San bernardino is an example of this. Were starting to get a new wave. I dont know where this attack in minnesota is which is no contact between the person and isis. The persons passive lly just absorbing isis. They have other things going on and then they go out and do it and isis comes up behind the fact and says look at us. It means that isis can take credit for things that they did inspire, didnt direct but just watched things happen in the United States and say that was us. We dont want to give credit to isis for new york if they had nothing to do with it. That would be playing into what they want. Tom, your thoughts on what were looking at here back to new york city. This is very close to where the bomb exploded on 23rd street last night. Yes, they surrounded this vehicle. Theyre not wearing any protective gear and not clearing people out of the area. What would they be doing now in. I think its more in the realm of suspicious vehicle. Maybe its been parked there a long time and local residents said weve never seen this vehicle in the neighborhood before. At this point they are treating it like a suspicious vehicle, not one they believe would have explosives that would warrant an evacuation. Thank you all very mump.

Youre looking at live pictures of investigators looking at a subaru surrounded by tape there. Its right near where the bomb exploded at 8 40 p. M. Whats notable to you, deb . Reporter what we tell you is that that truck thats parked in front of it is a flat bed which suggests that they want to move that car off this street and get a closer look at it. You may be able to see a detective there or investigator with a camera. They have been taking multiple pictures of that car from this angle. I was looking around to see if there were any video cameras belonging to the nypd. There is one at this busy intersection. I dont know sort of the resolution whether they were able to see something that perhaps allow them to identify this car as the particular vehicle of interest. The stationed marked police car right next to it. This is clearly something that might have some information. They are curious about and the fact it has new jersey plaits. Extremely significant if they can make some connection between the device exploded here and the device that exploded in sea view, new jersey yesterday. Were hoping to get a little more information on that car. Right now we believe they will take it away, certainly within the next couple of hours. Stand by. Lets bring back tom fuentes. A pipe bomb exploded in new jersey yesterday morning on that route of a military 5k run. They have said the authorities that there are similarities between the pipe bomb in new jersey and the explosive device in new york city. What will they will looking at to make a conclusive statement that indeed there is a connection if there is one. What would tell them that . Similarlity in wiring, dna . What would tell you that . The most conclusive would be if they found dna. Without that . The next step is bombs have whats referred to as a signature. When people make bombs they use the same technique. If youve made a bomb and at tend of the day you still have all ten fingers and toes, you dont deviate the recipe like a french chef. You follow it. It enables them to match up that the bomb has similar characteristics, the way the wiring, detonating, the actual explosive material. What was used a as a container with that device. Those are all aspects that would be similar or have some similarities. Thoughts to you as we look at these live pictures from west 23rd street tonight. I always want to remind people that the whole point of a big investigation especially in case like this, theyre going to be over inclusive. We may be seeing something that is not relevant. The fact youre not seeing them move people away or not in any gear suggests maybe its car thats been abandoned for a while and people are nervous. One explanation for why trash bin or other places is the person leaving them did not intend them to do the massive amount of harm. What we dont know right the psychology of the person but thats another way people might interpret, investigators might interpret the placement of these devices. I put that out there because when people wonder why isnt the nypd telling us what it is, it is because like in all of these cases, we need to let the investigation follow the intent of those intended harm on us but the evidence, physical evidence. Signature methods of making the bomb fingerprints, where that all will lead. Final thoughts from you as you talk about the context and experience you have from being commissioner during the Boston Marathon bombings to what we saw last night in the ensuing investigation. I think youve got some of the best investigators in the world that are on this. The fbi, the Counter Terrorism section. These people have vast experience and resources to pursue this properly. If someone wanted numbers of victims, there are a multitude of other places they could have gone to make this happen. It does make you wonder about the location. Thank you. We appreciate it. Coming up, well take you to that third potential terror attack thats being investigated as a third terror attack on u. S. Soil this weekend where the fbi says its it is investigating last nights stabbing spree at a mall. What investigators are discovering flexion. Youre live in the cnn news room. Glad forceflex. Extra strong to avoid rips and tears. Be happy, its glad. This is the new comfort food. And it starts with foster farms simply raised chicken. California grown with no antibiotics ever. Lets get comfortable with our food again. The fbi investigating a stabbing attack at a minnesota mall at a potential act of terror. The attacker was killed by an off Duty Police Officer. The police still not releasing the name of the suspect but isis, today, claiming that he was one of their soldiers. The Somali Community in minnesota has been a target of isis recruitment for years. While its unclear if the attacker was part of that community, somali leaders gat r gathered in minnesota last hour to speak out against this attack. We strongly condemn what happened last night. Thats not represent any religion. It does not represent any group, it does not represent no matter what. Theres no justification to keep or to excuse or reason to give about what happened last night. To the victims, were here for you. We will be there for you. This community is praying for you and we will be there in any capacity that you need us. We will show you support, love, respect and understanding. Nick has been following this story from the beginning. Walk us through what happened and at this point what they know about the suspect. This individual walked into the cross roads mall and began stabbing people. He was wearing a cross roads uniform. Whether or not he was contracted by the co
