a large perimeter.hings could be happening in other parts of the perimeter, you're not privy to on the outside. we heard nothing about any other sort of carjacking. does this belong to a friend, relative, stolen, we don't know any of those answers, the other question we don't have the answer to, how did he wind up in watertown in the first place? convenience, because it was near cambridge, or some sort of acquaintance he >> thank you, lauren. >> let's factor in to what we ju hrd as to our understanding of how things are unfolding. >> we received information a short while ago that the white house has been following this quite closely. the white house situation room was activated and been filled with top counterterrorism officials and as bill plante reported a short time ago, the fbi director, robert muller and the attorney general of the united states, eric holder were going to be briefing the president this morning. but apparently the white house, through the situation room, has been watching events unf

, it was a firm perimeter. they don't believe they lost anything out of the perimeter they set up but it was too smil. he eluded the perimeter by one block. he eluded capture until shelter in place order was lifted and law enforcement could once again count on members of the public to help them get this guy. wow. joining us now, nbc news white house correspondent kristin welker. how did the president find out about the capture? >> reporter: rachel, i can tell you according to administration sources, fbi director robert mueller made the president aware of tonight's arrest. this is the phone call that he has been hoping to get all day and really all week, if you think about it. robert mueller has been keeping the president up to date not only through the day briefing him, but really briefing him the past several days during this developing story. the president also held a briefing with his entire national security team early this morning, rachel, he's continued to monitor the swaying. we haven't really heard from

that was the perimeter they set up. this street happens to be a street and a half outside that perimeter. if people are home saying why didn't they see this boat today, they did set up a perimeter and this street was just about, i'm told, a street and a half outside of the perimeter of the extensive search they were doing most of the day. my source does believe that the suspect was injured. at least investigators believe he was injured last night in that firefighter. to what degree, we don't know. again, their main concern now is they still are going under the belief that he either has bombs with him. he may have one strapped to him. you know, specifically a suicide vest or something like that. and that is one of the biggest reasons why what they are doing now -- and they are not in a holding pattern. they are looking at his movements, trying to make determinations of what the safest, best way to bring a conclusion to this would be. >> that makes sense what you said about the injury. that's the one in which his older br

within that perimeter. then you establish a tighter perimeter to make sure the suspect can't get out. everybody's on guard, and you try to control all the officers from actually probing until you get s.w.a.t. teams, k-9 units and specialized units that are equipped, not only with more body armor, but they are equipped with weapons and they can work as a unit to start clearing areas, section by section. certainly, they use the k-9 to see if they can key on the trail. they will try to isolate a certain area. then they pull back and they make a tactical plan to start clearing that area, you know, room to room or area by area. and hopefully, they will contact the suspect and the tactical advantageous way. and if the suspect wants to engage, he will be killed. >> griff jenkins describes, they near a neighborhood with a lot of homes. i assume they are worried about the suspect getting inside someone's home and doing harm to someone. what are they doing to make sure that the people in the area are safe? >> caller:

but they asked us to move from the perimeter. the perimeter is very, very large. it is almost like it grew up around us from where we were previously located, a massive circle in all directions. this perimeter has really grown. every street corner is lined with these state police officers all the way down mount auburn street. we've just come to the end of it. at this point we're at least a mile away from where that tactical gear was gearing up and where the dozens upon dozens of people, probably a good 50 or 60 people were gearing up. the body armor and tactical gear and automatic weapons. it is unclear exactly if they have a specific location that they're going to, if something is imminent and about to happen or if they are just getting ready for something that they expect could possibly happen in the coming hours. but it's clear that they have widened this perimeter. people are still in their homes. we have seen almost no one come out of their homes to take a look around, to take a peek around. we've seen no one heading for their cars. apparently there are a lot

he is outside of the perimeter. still you have to operated with your best information that someone would have had to running quite a gait from the time the chase happened and the time the conflict happened to the time the police arrived and set up a perimeter. it would have been a feat to splip the perimeter but they have to operate on the idea that quite possibly he did. >> bill: mike, thank you. we're going back to our core dints within the hour. the police briefing is 25 minutes away. they made two statements today, no questions were taken at either one. we'll see whether or not that changes when they begin at the half-hour. to our chief intelligence correspondent, katherine heritage, she is working her sources. what is the latest developments this hour on the investigative side. >> reporter: tonight has the manhunt unfolds they are working multiple lines of investigation. fox news understands that all electronic traffic is being scoured including those youtube sites attributed to the suspects which included radi

he was just slightly outside of the perimeter that we set up. but in truth, we told everybody that this was a dangerous situation. and they should be cautious. this is a very dangerous time in the world. we have to use caution. that's what we asked people to do. thankfully, this man who found this suspect called us right away. did the right thing, got on 911, we were able to come in and take care of the situation. there's no report of explosives with him. but i have to tell you, i was at the scene last night, just after this incident occurred. there was an exchange of 200 rounds of gun fire. there were improvised explosive devices and hand made hand grenades thrown at the officers in the scene. this is the stuff in an urban police department, this is almost unheard of. these officers protected the community and they protected the -- each other, when they responded to this scene. i'm so proud of the actions of the watertown police, the state police, the boston police. incredible team. >> did he have a quote in the boat -- >> he did. i can't -- i

we had no indication that he had gotten outside of the perimeter. it was very chaotic early this morning. we had an ada, police officer, who was shot, bleeding. so there's a lot going on. we thought we got the perimeter solid, and we pretty much did that, but we were about one block away. so -- he had to be moving a little bit after he was behind a house for a period of time that we know. >> was he moving -- >> how did you know that you could take him into custody? had he been moving around -- >> the reason we knew this is our helicopter had detected the subject in the boat. we have a -- what's called a forward looking infrared device on the helicopter. it picked up the heat signature of the individual even though he was underneath what appeared to be the shrink wrap or movement. the helicopter was able to deliver the tactical teams to the area and ultimately take him into custody. >> was the boat searched during the day on the perimeter? >> yeah, it was outside the perimeter during the day. it was not searched. this was the act of a citizen who wen

but a perimeter has been set. down there, several police cars are continuing to drive in and out of this area. that's pretty much what we can tell you at this point. >> it was a dangerous situation with reports of 30 gunshots and explosives being thrown out of a car during this chase. right now is there a sense of urgency where you're standing? do you get the feeling that whatever is taking place is taking place within a mile of where you're at? >> reporter: there is really no way to tell how close we are to any potential action. i think it is still definitely a sense of urgency. still, residents are standing around in a very calm just very curious and inquisitive way. but certainly you get a sense there is danger, potentially not far away at all. >> lindsay we heard early reports that there was a 20-block perimeter in the cambridge and watertown area i assume you are just outside the perimeter. and a reporter was told to turn his cell phone off and the police officer said if you want to live turn your cell phone

we found blood behind the house inside the perimeter. we had information that he had gotten outside the perimeter. it was chaotic early this morning. we had a police officer that was shot that we had to aid. without we got the perimeter solid and three much did that. we were about one block away. he had to be moving in little bit after, he was behind a house for a time. >> how did you know you can take him into custody? oure reason we knew, helicopter had detected the subject and the boat area we have a forward-looking infrared device from a helicopter. he picked up the heat signature of the individual in the he was underneath a cover on the boat itself areas there was movement from that point on. the helicopter was able to direct the tactical teams to that area and ultimately take him into custody. it was outside the perimeter during the day, it is not searched. this is the act of a citizen that went out and discovered this individual in the boat. and alternately called the watertown police department and resulted in this result. >> [in

anybody on the perimeter be aware of cross fire situations. >> be advised f.b.i. possible launching a device. stand by. nftd device and do not return fire. it is a flash bang. >> all units don't return fire. there might be a flash back. don't return fire. >> no further movement at this time. >> no mother movement in the boat at this time. >> we have him on his back. his arm is blood and he brought it back down. heap's on the left side of the boat looking at it from the driveway. >> he's on the left side of the boat. >> the boat. >> his head to the left of the boat when you are looking at the boat from the driveway. his head is at the left. >> hold. i am not sure if they will work their way on the boat again. i don't want you on top of the boat while they are doing anything. >> we'll meet you. >> keep an eye on the garage. >> he's in custody. >> he's in custody. suspect is inody. subject is in custody. >> good job, gentlemen. >> and with that, the day of fear all over the region over. mike to bin 10 mimes out've boston what is the scene tonight? >> shepherd, people

most of the police are holding perimeters. it will involve swat teams and disposal teams and we have seen a lot of canine units here, who may be put into use some level, either to determine if the suspect is alive or dead or to determine if there are explosives with him. hear it? >> lester, i have a woman on with us from the neighborhood. rebecca krieger, can you hear me? >> hello? >> hi, rebecca, this is brian williams, are you on basically the same street as the house. >> caller: yes, i'm on the street behind. >> what has been happening. >> caller: there was a bunch of shots less than a block away from me, they were very rapid, a bunch, quickly and then a bunch of police cars, probably 40 swarmed the area. and then since then, there have just been cops piling out of the cars and running towards what seems to be the suspect with pointed guns and you know, running in and running out. it's very scary. there's a lot going on. there are helicopters overhead. and there have been those trucks that have like a jail cell in them, the

a perimeter. as we said, it was very chaotic early this morning. we had a-to-aid a police officer that was shot, bleeding. so there was a lot of things going on. we were about one block away. we thought we had the perimeter solid but he had to be moving a little bit after. he was behind the house for a period of time. >> reporter: when you got there, though, was he moving -- how did you know you could take him into custody? had he been moving around? were you able to watch him? >> the reason that we knew this is our helicopter had actually detected the subject in the boat we have what's called a forward-looking infrared device on that helicopter that picked up the heat signature of the individual even though he was underneath what appeared to be the cover on the boat itself and there was movement from that point on and the helicopter was able to detect the technical teams over in that area. >> reporter: have the police searched the boat? >> reporter: (inaudible) >> it was outside the perimeter dur

we had enough officers on the perimeter.ckly set up officers in strategic positions along the perimeter, as the superintendent took control of the entire incident. >> were you worried they were coming from within that boat? >> there's always a possibility. just that there were shots coming from the boat. and my thoughts was the safety of the officers and the citizens that were still in the area. >> were the shots coming from the boat? >> that's part of the investigation. >> did you have anything to do with the shots that were being fired? >> no. >> was it a shootout at the boat? >> again, that's under investigation. you know, as soon as we had gotten there, we detected movement in the boat. we could see a hand up, poking at the top. whether they were trying to, you know, poke a hole in the top, or if they had a handgun, we weren't sure. you know, but clearly from everybody's vantage point, we could see whoever was in that boat was poking at that top. and so, you know, that's, again, when we got there, we clearly knew that th

we are on the edge of the 20-block perimeter.han half a mile away from where the shootout took place. we have had prior to now maybe about a dozen neighborhood residents who have been standing out on the streets and they were told that around 2:50 this morning they received a call, an automated call saying to stay inside their homes. that an incident had occurred. many of them still curiosity brought them out to the corner. they now appear to be listening and they appear to go back inside their home, as they have been advised. watertown police plan to go door-to-door knocking on people's doors and for people not to open up the door unless it is a uniformed officer, someone who identifies themself as a police officer. in the meantime here, continues to be a large police presence of state police, fbi in and out of this area. john? >> linsey, this was a public safety mode that the police were saying. they wanted to make sure that everybody was safe, as you jusm. they created this 20lock perimeter. still armed and dangerous the man t

it was outside the perimeter during the day. it was not searched. this was the act of a citizen that went out and discovered this individual in the boat and called the watertown police department resulting in our response. >> is there a chance the suspect won't make it? >> i don't know. i didn't see him when he was taken into custody. he's in serious condition. i don't know to what extent. >> i think we have taken enough questions for now. thank you. >> thank you very much. >> there we have it. the news conference after tonight's apprehension. the suspect is alive. a couple of notes. and that is the achievement of science. something like forward-looking infrared that from a helicopter high above saw the heat signature of a human body under that winterized white vinyl they wrap boats in to get through the season. number two, let's hear it for digital photography for all the folks going back to eastman kodak and bell labs who developed it. it will end up being such a critical part, such a ctical reason why this case was resolved so quickly. to the whi

the car , behind a house we had no information he was outtide the perimeter. it was very chaotic early this morning. a police officer shot, a lot of things going on. we thought we had the perimeter solid and we did but we were about one block away but he had to be moving a little bit after he was behind the house for a period of time. >> when you took him into custody was a moving around? >> the reason we knew because our helicopter had detected the subject in the boat. rehab a forward-looking infrared device that takes death of a key signature even though he was underneath the cover of the bowl and there was movement and a helicopter could direct the tactical teams to that area and taken into custody >> it was outside the perimeter during the days a was not searched. >> this is the active as it is in that discover this individual and ultimately called the watertown police department that resulted in this response. >> is it possible he will not make it? >> i don't know. i did not see him when taken into custody. he is in serious condition but i don't know to w

outside of the perimeter as well.n looking. for example, up in cambridge where the two suspects lived, they searched a massive section of the city, even though there was no indication that they were there. it was just outside of that 20-block perimeter. >> bill: wesley lowery is our reporter for the "boston globe"," you can follow him on twitter twitter @wesley lowery. i understand you were in watertown when police discovered where they fled with their suv. describe that scene us to. >> horrifying was the only word i have for it. i was at mit immediately after the shooting at that crime scene, and i was discussing with police officers -- for those who are not reporters, they may not understand there's nothing more tense than a situation where a police officer has just been shot and killed police are markedly vigilant about guarding that scene and perimeter. i was talking to these officers, and they literally dropped cups of coffee out of their hands, like out of a movie and jumped in their car and spread off. and i kn

going back to the perimeter, megyn.n the darkness of night, trying to secure a circumference of two miles of densely populated houses and businesses with all the chaos going on and to be able to successfully really chain a security perimeter around that so just a human being cannot slip through. it's really difficult. so it's not something that would be, you know, out of the realm of possibility that it happens more often than not. >> yep. >> megyn: we'll continue to watch it. up next we go live to the white house. stay with us. anyone have occasional constipation, diarrhea, gas, bloating? yes! one phillips' colon health probiotic cap each day helps defend against these digestive issues with three strains of good bacteria. live the regular life. phillips'. >> megyn: there are breaking developments in an unprecedented manhunt for the second suspect in connection with the boston marathon bombings that left three people dead and more than 160 injured. a brand new hour of "america live". welcome, everyone. i'm megyn kelly.

they have set up a perimeter in that area already and they start to tighten up that perimeter thinking if we've got him boxed in we'll search house to house. but many hours later they still haven't found him. >> rose: the man whose car was -- vehicle was hijacked and then released, what does he say? >> he says that they jumped in the car, that they kept him hostage, that they threatened to kill him and at some point they stopped the car and threw him out and kept going. >> rose: did they tell him why they were throwing him out and not killing him? >> at this point i don't have the details of the conversation beyond those snippets that he was threatened and then they dumped him. >> rose: we assume he's on foot or has anybody reported missing a vehicle that he might have somehow hijacked or been able to getting access to? >> they've gone through that process of identifying vehicles. he might know where they were or have access to and so far they've accounted for those vehicles but in the time between that they put out multistate alarms for those vehicles only to cancel them a couple days

the white house has a perimeter, the secret service expanded that perimeter further out just out of anbundance of caution. mayors across the country saying seattle denver illinois police departments on heightened alert. no specific threats in those cities. of course, the common theme from city halls is that we are all in this together. if you see something, say something, shep. >> shepard: eric shawn live new york city's times square. thank you. continuing coverage ahead of the o'reilly factor from new york tonight in 60 seconds. >> shepard: one minute before the top of the hour. recapping the news as we have a it from boston this afternoon. the explosions happened in the moments before 3:00 p.m. the last marathon runner recorded to have crossed the finish line at 2:57. then one explosion and 12 to 14 seconds later another explosion and now we know two people are confirmed dead somewhere around 100 are injured. boston hospitals took in injured this afternoon and at latest word a number of patients were listed in critical. the investigation has begun. there is a person of interest being

>> well, alex, you normally have two different perimeters.ou have an outer perimeter that is -- you believe is the furthest distance out that either the subject could go or that his weapons would be functional. and then you have an inner perimeter, if you know exactly where he's at. and again, watching and listening last night, it sounds like that this 20 block perimeter that they threw around was, you know, should have been 21 blocks. that somehow, where the vehicle was abandoned, and the shooter, the subject took off running, he must have been at a dead run in the middle of the night, and got far enough away, found this boat, and was able to hide. and the boston police commissioner had suggested he may have been in that boat from the time of the shooting, till the time that the fbi finally took him out of that boat. >> clint, i'm sorry. my ifb dropped out. are you still with me on the phone? okay. i don't think we have a connection with clint van zandt right now. a little bit of technical difficulties. we're going to try and reconnect with

that he had gotten outside the perimeter. as we said it was very chaotic early this morning. we had to aid a pleas police or that was shot. we thought we had the perimeter solid but we were about one block away. he had to be moving a little bit after he was behind a house for a period of time that we know. >> how did you know that you could take him into custody? had he been moving around, were you able to watch that? >> the reason that we knew this is our helicopter had actually detected the subject in the boat. we have a what is called a forward looking infrared device on the helicopter and it picked up the heat signature of the individual even though he was underneath the shrink wrap or a cover on the boat itself and there was movement from that point on and the helicopter was able to direct the tactical teams to the area and a ultimately take him into custody. >> was he in the boat during the day? >> it was outside the perimeter during the day so it was not searched. this was the act of a citizen that went out and discove

there's a 20-block perimeter of the area that the chief devoe just spoke about. we believe that this to be a terrorist, a man who's come here to kill people. we need to get him in custody. one thing that i want to say is there have been two police officers, one killed and one badly injured. our sympathies go out to chief mcmillan and to the families of those officers. this is a terrible tragedy. we don't want to increase it. we want to be very careful of what we do. >> folks, we got to get back in incident. we'll be back in about an hour to brief you again. thank you. >> you have been listening to an impromptu -- >> remarkable developments overnight in the case of the boston marathon bombing. you're hearing from law enforcement officials in boston, massachusetts, one of the suspects has been killed in a firefight that took place with police last night. at least another suspect is at large, the one that was referred to suspect as number two in those photos that were released by law enforcement yesterday. he was the one wearing the white cap, he's believed to be ar

they seem to be holding this now as one of the perimeters. >> we're back here. a simulcast with brian williams and pete williams. you and i were getting unconfirmed reports of a boat with a body in it. >> there is a boat with what looks like a body under a blue tarp on the last house on franklin street in watertown. we hadn't had that confirmed. pete williams has not completely confirmed that yet. it appears that they have surrounded the area. people standing outside just now on our camera don't appear terribly concerned. we don't have an identification of this body so we don't know if this is the suspect or some other citizen. but -- so that is one question. right now, by the way, just looking at the white house picture behind you, there's a tornado warning. >> i can hear it. >> we are getting august weather. >> the white house, as you can see, is working behind you and in that white house within an hour or so we understand the president spoke to vladimir putin. >> let's go to erica hill on the scene. can you confirm what you're getting about a boat, blood, a b

he may be within that perimeter still. would dictate that he goes to nearest dwelling like chris dornin did, the ex-cop out in california. he made his way to an area where he could actually see the command post. >> we've had many, many experts during the course of the past few hours talking about the device that was used. we need them to believe essentially that this 19-year-old suspect is an amateur terrorist. and yet the law enforcement agents have no idea where he is at this point, although they believe he's somewhere in the state of massachusetts. i'm just wondering, are you surprised at this? that this kid has been able to get away, just elude the authorities for so long? >> let me change that, yeah, absolutely. but as the guest said, good friend from the fbi, in the chaos that happened afterwards, particularly when you had that big of a firefight, plus using some of the tactics you see in other place where is they won't go out without a fight and look like they want to go down in a blaze of glory. safety and chaos ha

>> i am told that it is about a 15-20 block perimeter. the reason why is because they don't know where he has gone. they also don't know where there could be any other explosives. so they are working the crime scene and the only people you see coming and going in and out of here have sirens and blue lights on top. they are trying to keep residents from moving around. they don't know what is out here but they know it's a dangerous area by all accounts. suspect on the lose. >> let's go back to bill hemmer in boston. bill? >> this is a message to the mit campus. an mit police officer shot and killed on campus in the line of duty. we have posted a brief news story. while the circumstances around his death become an active investigation officer david blythe while defending the public. classes have been canceled for the day. we heard from the doctors who treated suspect number one said he died of massive drama wounds which is a combination of several gun shots and also explosive residue on his body at the time. what around irony that would be i

there's a 20-block perimeter around the location that chief devoe has just talked about.e're concerned about securing that area and making sure that this individual is taken into custody. we believe this to be a terrorist. we believe this to be a man who's come here to kill people. we need to get him in custody. one thing that i just want to say is that there have been two police officers, one killed and one badly injured tonight. our sympathies go out to chief mcmillan who has a severely injured officer in the hospital and to the chief of the m.i.t. police and the families of those officers. this is a terrible tragedy. we don't want to increase it. we want to be very careful here. >> folks, we've got to get back. we'll be back in about an hour to brief you again. >> that is coverage from our boston affiliate wbz. you heard police officers urging people in the town of watertown to stay calm and stay in their homes. watertown is a suburb of boston. we're going to continue following this story throughout the morning for the search for the suspect. this is the "cbs morning n

it's highly likely he's still within what's called the cordoned area, the perimeter. they're tightening the noose on this individual and we'll know soon. >> there's a sense, though, that the older brother was the mastermind behind this. we don't know if that's right or wrong. but clearly, this is now the younger brother. he is on his own. do you think that he has the same commitment, if you will, to this experience, as his older brother and the mastermind of this? >> well, it's been reported that the older brother posted on his social media website statements about being disenchanted with america, not having friends, not understanding americans, and it strikes me that he, as you said, probably was an influence on his brother. he was a boxer. we know that he went abroad for an extended period right before these events. the younger brother, on the other hand, was just made a naturalized u.s. citizen. and i think where we are right now, we have to assume that both are equally motivated and both are equally armed and dangerous, but he is tired, he's been running on adrena

around the perimeter boat. the f.b.i.made an entry into the boat and removed the suspect, who was still alive, in the boat. >> can you talk about the imperative of taking him alive. >> we always want to take every suspect alive. >> i understand that, sir. can you talk about this individual, you can talk about accountability. >> we always want to take something alive so we can find out what happened, why it happened, and we can hold them to justice. >> [unintelligible] >> there hostage rescue team did work trying to negotiate him, they did try to talk him out but he was not communicating. >> [unintelligible] >> i actually don't have that information. >> that you got your guy, this is it? >> i think based upon our investigation at this point in time, the citizens of the city of boston and this area can be confident that the threat has been removed. [unintelligible] >> the suspect is in serious condition at the hospital. >> how do you know this is the suspects that you're looking for? they did not rob the 7-eleven so how did

your goal is to keep sterilization on the interior of the perimeter. what they're requiring to do is expand that perimeter through different pes of technology. obviously it is explosive detection k-9. that's why we're so busy. i think what we are trying to do is makes a big a deterrent as possible. and expand our scope --. melissa: companies are trying to do that? companies are trying to expand their perimeters and make their facilities safer, is that what you're saying? >> absolutely. as well as relief some anxiety that employees and pedestrians are going through at this time. granted this happenedn boston, not new york. melissa: yeah. >> people feel the same sense of insecurity right now universally across the country. melissa: kevin, i always wonder as companies and individuals get more people in the mix, when they hire more people to do surveillance, to add cameras which are good but also to be on foot, walking around, to have bomb-sniffing dogs, does that help or does it complicate things? >> it helps. the more eyes out there looking for things th

he did get outside the police perimeter. what you're going to see as the day unfolds, though, as marthaened others pointed out, he may be able to pull this bombing off but he's not really a savvy criminal, if you will, and his world is going to continue to narrower and narrower and if the police are lucky to stop that vehicle in some way and i guarantee you, they're going to stop it where they don't have to approach it. but, if he would happen to get away, he's g because, curious, obviously he was able to commune yesterday with his father and his family, assuming they had cell phones, is he capable of communicating with anybody now, if he uses that cell phone, will police be able to zero in on him, do they already know how to find him that way with the pings? >> well, what we don't know is how many cell phones he has, the we don't you can dozen know if he has that. yes, if he used the same phone that he talked to his father on, they probably can get up and maybe be up on that phone. it's so easy to buy throwaway phones. >> i

and they have a broad perimeter. they're searching and want it find this guy. uncle starts to speak and they're from chechnya, formerly part of the soviet union. they came here ten years ago as boxers on a sporting event, essentially and emigrated here legally. and right now, the police surrounded and approached with guns drawn a house in watertown, greater part of boston and we saw a woman with a red jacket led out of that house, where it stands. one terrorist dead. one on the loose and he is maybe cornered in that watertown area. monica crowley still with me. the police are worried -- first of all, do you know for a fact that these two terrorists are devout muslims, do we know that? >> well, from what we're seeing on social media at least one of the brothers claims he is a religious-- or was a religious devout muslim. >> one of the terrorists, shot and died in the hospital was found to have an ied in his body. and the other one, is there any speculation, but is there any suggestion that he, too, might be similarly equipped? >> there is some speculation and th

they did a perimeter search around my house. it was clear that they were working very hard to track down where this second suspect was hiding. >> greta: how far was the house with the boat behind it from your home? >> about 200 yards. it was right down -- it was right next-door. gunshots are very loud in person. it was too close. >> greta: so how do you describe how you feel tonight? >> it is mixed emotions. thoughts are with people that have suffered great loss and people that are struggling with injuries that were sustained and the families that have loved ones that are hurt. in watertown, it's a gigantic relief. i'm very proud to be from boston. i feel kind of honored to be from boston to be honest. >> greta: as i look at it, i am so happy for the people of water town but then i think of the people in hospitals watching this. week ago they were participating in a marathon and tonight they have to learn to walk with a prosthesis. as people applaud tonight we have to remember this is really an ongoing problem and tragedy and so

they set off a crime scene perimeter.s about a six block radius and nobody will be allowed in there. >> okay. thank you for that. peter was on the scene it has been a long day. >> and somebody on the scenes. watching from the sidelines when the blasts went off. here is how he described the scene. >> and then i heard a big explosion about 100 yards down. further from me towards the finish line. it looked like it was on the sidewalk or perhaps the parking lot and i would say the smoke went up as high as a three or four story building. about 20 yards from me another big explosion. i'm not entirely sure. then people started scrambling. people were terrified. this one was awfully close. then i looked to see about six or seven people strewn about that area down on the ground. everyone was scrambling to get out of the way. i saw what looked like separate six or seven people being treated by emts or plifs. >> he is one of the hospitals where the wounded had been treated. i can only imagine the stories that you're hearing and love

and establish a perimeter at that point in time.e suspect is, or do you believe you know where the suspect is? how can you say he's armed and dangerous? >> may i? first of all, i don't think that the instruction lends itself to, you know, simple phrases. we are where we were effectively on -- as of monday night, or tuesday morning. it was a couple of exceptions. one of the suspects is dead. there was a fire fight out here last night. some 200 rounds. and explosives. so we were very justified, i believe, based on what we understood about the investigation, in taking what we knew was a big step in asking people to stay indoors while we went house to house here, and in other communities close by, to which we believed the suspect, or law enforcement believed the suspect could have fled. the investigation has continued to develop. we can't give you all the reasons -- all those developments right now. we will in the fullness of time. we can't right now. but based on those developments, we feel it is prudent to be able to say to people, yo

and other things within the perimeter protection there is some surveillance that is a component of the cost of that. of a large component of the cost on the perimeter protection is the ratings of the individual ball ardz from the building while our current orientation is to move the ball ardz, we would have a means of calculating the cost impact there very directly from -- because we have the same types of ball ardz as type of the bids is the quantity of each bid so we can calculate that but at this time we were envisioning not a bit alternate but to move the diameter out. we can potentially package that as an alternate if so directed. >> my suggestion is the action before us today is really just to prove this direction or this guidance for our architects. i think we are getting ready to pass that item. my suggestion is that we add a resolve clause or add to the resolve clause what director reiskin has suggested and we can make that amendment with a roll call or with a vote. i don't know if you feel comfortable rephrased that again we can add that to the resolution. >> again, it's not

we've got a good perimeter on the two that ran westbound. go up there and cuff him. man: get him off! okay, get up. he's already handcuffed. where are you at, colonel? okay, it's cracked. there's keys in it. that's a fake key. the ignition is in the "off" position. they punched the column on the other side. started it with a screwdriver. but they stuck a key in it so if the police pull up they think the police will think the car's not stolen 'cause they see the key. however, if you're a good police officer you'll see that it's not cranked forward which would give us a hint that the car was stolen. irwin: it went up the alley just west of 31st and graceland, northbound and then they bailed out mid-alley. four of them jumped out. the vehicle continued northbound and hit a fence. we took off on foot after two of them. the subject in the orange hat was the driver the subject in the green michigan jacket was the back seat passenger. this car that you had in pursuit it's stolen. it's punched, no keys in it and the owner's signing a verification right now. okay, that's what

the perimeter and was there enough personnel tutsi-led off? the answer to both is yes. i have a feeling he got as far as he could until the perimeter started to close and then he found the boat. greta: i understand that the bombing was planned obviously they had to make the bomb and figure out a way to deliver and drop them and get out of there but then they stuck around. this is their neighborhood and a city and ttey never left and that is baffling. >> i would agree and i don't suspect we could answer that question. i and my sure he will but if you look at the evidence they did not apply all of the items that the marathon is a lie suspected another location they did not count on the fbi investigation of this surveillance video and the ability to look at multiple photographs to narrow down to both individuals planting those bombs. i think they thought they would have more time. >> there will not get away with it because those were plastered across the of world. everybody saw the videos and was ready to call in the tip. that was very smart of t

an entire perimeter was set up in a 20-block radius. we went to one location because it seemed there was a staging area. that staging area was where you see those lights. the traffic lights. there was activity there where you had a lot of law enforcement, a lot of law enforcement in tactical gear, riot helmets and the like. that was this morning. >>> now, second location. you've got police questioning somebody. talking to somebody. but because of the way the cars are surrounding this particular individual, it's likely that he didn't have any sort of device on him. that's really what law enforcement is fearful of is, wolf, is this person on this wild ride, that he may have, in fact, dropped several pipe bombs. and that's the concern that officials are having. that's one of the big reasons that they told people that they really just need to shelter in place. so that is the active scene going on right now. the first scene this morning, that is a home, investigators, law enforcement very, very interested in a home. they are now searching th

one, before they let that perimeter go they reassess. is there some place we need to go back and cover within this box? is there some place we did very quickly that we might want to do again with -- you know, more slowly. is there anything going on with tracking dogs or so on that gives us any indication there's a trail that we can still follow but after they that they go to the command post and say now we have to widen the perimeter to anywhere he could be and that means going back to where we were yesterday. here's his picture, this is who he is, this is what he's done. we need the public's help. >> rose: let's retrace the events starting with the fact that all things were unfolding in watertown this morning. what happened? i want to go from what happened to the fact that he has so far eluded capture. whahapped was a seres of frightening, dramatic events. it begins with some kind of incident at a gas station that has a convenience store attached to it. some kind of robbery. a description goes out of a car. at this point these two indiv

we set up a perimeter around the boat and over the course of the next hour we exchanged gunfire with the suspect and ultimately the hostage rescue team and fbi made an injury to remove the suspect who was still alive. >> talk about the imperative to take him alive. >> brieux's want to take them alive. >> via understand but talk about why. >> we always want to take somebody alive to find out what happened. >> how badly injured? >> the team did try to negotiate him and talk kim but from what i've understand he was not ccmmunicating. >> i don't have that information. >> do you have your guy? >> based upon our investigation this is a since of the area can be confident this threat has been removed. >> the suspect is in serious condition at the hospital. >> he did not rob the 7-11 how did you know, ? >> the suspect came to our attention after a vicious assassination of the police officer at m.i.t. and the subsequent robbery that occurred we have videotape from a gas station. it was actually a carjacking and the officers to engage them with other officers. we otherwise could not put the cas

we've also seen the white house perimeter moved out and across pennsylvania avenue. there is a kind of a -- not quite a lockdown mentality, but i would imagine we'll have reservists with automatic weapons in new york's grand central, if we don't already, laguardia and so on and so forth. >> yes, that's already been ordered for new york. i think part of that is until they know for sure what this was, the prudent thing is to assume that this was the beginning of something that could be going on elsewhere. no reason to think that. but the smart thing to do these days is to take those precautions now in case, you know -- the other thing is they have to worry about copycats. somebody else trying this elsewhere. this sort of circumstance, you know, of course, we're reminded of the olympic park bombing in atlanta. the other thing this call to mind is somebody leaving a backpack, and it turned out to be someone who was a whi supremacist convicted of this, leaving a backpack on a bench in portland, waiting for the martin luther king parade to come by and the device was to be
