i will be anchoring from boston tomorrow at 11:00 to 1:00 a.m. thank you for watching. erin burnett "outfront" "outfront" starts right now. >> "outfront" next, breaking news. the surviving suspect in the boston marathon bombings, dzhokhar tsarnaev speaks. the chechnya connection and whether the fbi could have stopped a man seemingly set on a path to terror. and the wife, who is the woman who married tamerlan tsarnaev?

good evening, everyone. i'm erin burnett. breaking news, new details on what motivated the boston bombing suspects. i want to get to jake tapper live in boston. what have you you learned? >> reporter: according to a u.s. government official, talking to me, the investigators have been working very hard trying to get information from dzhokhar tsarnaev. what he has been able to tell them in these preliminary investigations indicates that, according to him, according to him, all of this information needs to be checked out and followed up by investigators, but according to him, the brothers were not in contact with any foreign terrorist group. they did this on their own. there was a big on-line component to how they were self radicalized. they watched videos on-line. they downloaded information on-line. they did not have e-mail communication, but they were very much self radicalized, self

starters on-line. in addition, dzhokhar is saying the older brother, tamerlan, was the driving force in their action. that they were motivated by traditional jihad motivations. which is to say there is a religion and political component to why they did what they did in this twisted world view. and the idea being that islam was under attack and that they needed to fight back. but all of this needs to be checked out by investigators and they will be making sure to find out as much information as possible. but erin, the bottom line is that this is the first information we have from dzhokhar to investigators. he's been communicating this in a debilitated state through writing and one-word answers and nodding his head. that's what he has been providing so far. >> i guess a crucial question as we get ready to talk about all

of this, this is incredible all of the information you have. i would say sum from what you were saying this is what they were able to get from him before they read miranda rights. this would have falln in the category you can't use this in court but this is what we needed to know if it was more substantive or is that unclear? >> it's not clear whether he provided this information before or after he was read his miranda rights. i don't know. . i know, this is according to a government source, what he has told them in the preliminary investigations. >> jake tapper, thank you very much. obviously significant information there. new information from jake tapper. i want to bring in our panel live tonight. seth jones associate director of the security defense policy center at the rand corporation. former member of the joint terrorism task force and jeffrey toobin our legal analyst. jake is saying -- this is significant in terms of the information in this. but obviously a crucial question

out there which is was it obtained before or after those miranda rights were read? >> the irony here is what he is saying is not particularly helpful to him. what would be helpful to him is if he had a conspiracy he could make the government to make a deal to avoid the death penalty. if he is simply saying it is me and my brother, what does he have to negotiate with? >> there's no one to else to give up. >> right. >> and frankly, i'm not so sure the miranda issue matters so much. there looks like so much evidence in the case any way. >> they don't even need it. >> what difference does it make if they have a confession from him from his hospital bed? >> right. >> he's going to get convicted any way. yes, and that's a legal issue that may have to be sorted out but in the larger scheme of the case i'm not sure is it matters much at all. >> the older brother was

watching jihadist videos. do you think this makes sense. he was simply inspired by them and no one else was involved. >> that appears to be the case right now. one of the details that has begun to emerge today is they were inspire ed by the lex churs of anwar ail wacky. he was killed by a drone strike in yemen but he has emerged as an influential figure. they told multiple versions of "inspire" magazines which they used to construct the bombs. we are seeing influences on the brothers. >> also said the older brother was the ring leader. all the media coverage has gone in that direction. mostly because the younger brother's friends gave a mor tra portrait of him that didn't fit with what he had done and the older brother, going over and perhaps being with jihadist did. do you think this kid is

sophisticated enough that would take the blame off of him. >> it is hard to imagine what's going on. he just came out of lengthy surgery. he's been shot up. realize he's only been talking to the investigators for a period of hours. these interrogations take a long time. the first day is generally, or the first week or more is generally repore building. they will let him tell his story and try to build up a comfort level with him and then realize the investigators are pouring over tons of information to see which facts check out and which don't. as the pa ror is built and hopefully the continue a dialogue they may start to confront him with things that are going against what he is saying. it's too early right now. this story is likely to change and evolve the more it goes on. >> did didn't he admit to doing it? >> he appears to have a admitted

to doing it but i don't think there is any dialogue with investigators now. he is represented bay fine lawyer as i understand it and the last thing in the world the defense lawyer will do is let his client talk to investigators before he has had a chance to make a deal. maybe he will say, you take the death penalty off the table and you can talk to him all you want. but only then would he make that deal. >> does this open the door that the younger brother, assuming this version ends up as they go back and forth continuing to be proven to be true the older brother inspired him he may not know who was inspiring or linked to the older brother. he may not have all of the information they may need. >> that's possible. the evidence here is not just the interrogation, the interviews with the younger brother. it's going to continue to be looking at the the range of issues from internet traffic sites visits, kinds of lectures

on-line that were looked at. and other information based on interviews of people who knew them, including friends and college colleagues and family members. the alaail lackey people is a concern because he inspires people after his death. martyrdom may have increased his radical scope. >>. >> can someone relook at websites and figure out how to make two coordinated bombs like this. >> yes. >> seems pretty hard to me. >> yes. in particular, there are some pretty decent details on one of the inspire magazine editions that provides details that are actually fairly similar to what the brothers put together for this one. i think you can get relatively close. >> if the older brother is indeed the ring leader and the younger brother makes the case i

was brainwashed. if this goes forward and proven that they have done it do you think the younger brother will get less because he was brainwashed. >> by no means. for better or worse he is the only defendant in the case and he will have to take the heath for all of those deaths for the 8-year-old boy. >> regardless of his role, brainwashing is not a legal concept. if his brother influenced him -- he still participated. and again, if that is how the evidence plays out. and remember, this guy was partying with his friends at u mass dartmouth the days after. >> no remorse. >> this is not a robot programmed by his older brother to kill. he's got a long way to go to prove that he somehow didn't have free will in this situation. >> everyone stay here for a moment. i want to go to jason carroll in boston live with new details. when you talk about suspect two,

dzhokhar, today he spoke his first words at least as far as we are aware two investigators in a bedside hearing. what was the suspect able to tell investigators. people were saying because of the damage from a gunshot he may not be able to speak and only rely on writing but that doesn't seem to be the case. >> it was clear from today's proceeding he wasn't able to speak. it was clear from the transcript that we saw that he clearly understood everything that was happening around him. this first appearance was a bedside appearance at beth israel. we're told it lasted ten, 15 minutes. it happened 11:30 this morning. basically what happened is all the key figures entered the room. you have u.s. district court judge marion ballard, court reporter, attorneys on both sides and during the first appearance is where he learns about the charges he's being faced with, most notably using a weapons of mass destruction. in addition to facing the death

penalty, if convicted. it is a nine-page transcript. i want to key in on the key moments here. at first, you have the judge saying i will ask the doctor whether or not the patient is alert. you can rouse him. dr. odom says how are you feel something are you able to answer some questions. the defendant nods affirmatively. at that point they go over the charges he's faced. the penalties he's faced with and the court says if at anytime i say something you do not understand, interrupt me and say so, is that clear and again, the defendant nods. the only time we actually, according to the transcript, he actually speaks is when the discussion is raised about his attorney and what he can and cannot afford. the court says can you afford a lawyer? and at that point the defendant says no. the court says let the record reflect that i believe the defendant has said no. finally the court entered in to

record at this time at the conclusion of the initial appearance i did v find the defendant is alert, mentally competent and lucid. he is aware of the nature of the proceedings. once again, this is a first appearance. the next legal step, erin, for him will be his arraignment and that should take place within the next ten days or so. >> obviously important. as jason says it was just a word but it opens up the fact whether he can communicate verbally. you heard jason read from the hearing, from the transcript that we have. the defendant is quote alert, men tammly competent and lucid. so that means that that is -- i'm not sure is that a legal or medical assessment but everything he says can stand. he is not groggy or not with it. >> if he were unconscious or

incommunicado, this couldn't proceed. but now it can proceed and move forward. there's a long way to go. there's a lot of investigating left to do. >> it is going to be a year to trial probably. but at least the process is now under way. if he were uncon, still the process wouldn't have begun yet. >> one thing that is interesting and i know the legal process has to work its way and that's the great thing about this country. >> you don't sound convinced. >> i do. but i'm setting up something to go faster. we got a new series of photos that adds to what they were saying earlier, they believe they have the evidence. this shows them working through the crowd at the marathon. they have a video of suspect two putting the bag down and fingerprints on a tree and bbs in his dorm room and pyrotechnics. if it is a slam dunk case, and i

ask you if you think it is and ask you why will it take a year. is it a slam dunk case. >> i'm not privy to all of the evidence but what is coming out, with more and more reporting there is a lot of evidence, including the statement of the carjacking victim where the brother says we are the ones that did the bombing at the marathons. so you have eyewitnesses. you have -- they conducted the investigation, you have all of the physical evidence. it seems like a pretty good case. i would think a prosecutor would have happy to have all of this evidence. >> this doesn't look like a whodunit. >> why will it take a year? >> fair question. think of all that has to be done here. all of their phone records, computer records have to be analyzed and turned over to the defense. all of the scientific evidence, bomb analysis, trying to tie the fabric that was found around to the backpack that he may have had. >> that is if he is going to

trial. we have had other cases where the attorney says, look you have to get in here and do the right thing fast. your only chance is to strike a deal with the government and set this right. >> for life in prison. >> yes. >> that's the best he's going to get. >> that's the best he will get. >> and i don't know the answer to this, is the best strategy for the defense try to make a deal right away, or is it kick the can down the road, delay, let passions cool, and then make a deal? and will the department of justice be amenable to any sort of deal at any point. four people died here, including an 8-year-old boy. maybe they are saying, you know what, you just lost your chance for a deal. this is why we have a death penalty for people like you another reminder of the people who are struggling with these amputations. i mean that's going to be. >> you can plead to the indictment without the charges. and say i will plead to the

indictment. he wanted to -- that's it. done. >> could happen. >> thank you very much to all of you. good to see you tonight. up front next, what do the terror attacks have to do with one of russia's most troubled republics dagestan and the fbi accused of missing something crucial that perhaps they could have prevented it. is it fair. and she was married and had a child with suspect number one but her attorney says she knows nothing about the attack and how easy was it to make the bombs that killed three and injured dozens more. we went to a special place in this country that recreated the boston bombs. we will show you that. we investigate. woman: everyone in the nicu -- all the nurses wanted to watch him when he was there 118 days.

tlont is eviden tonight there is growing evidence that the older brother tamerlan was the leader. briern todd is "out front" live in boston right now. you have information on the visit which was bizarre by the accounts of everyone who was there that day, right? >> reporter: sure was, erin. it was actually the second outburst he had in a couple of months. officials at that mosque are telling us the first came in november when he confronted someone during a service, someone speaking at the mosque. that confrontation was not as clear and not as inflammatory as the one that came in january. this is january 18th on a friday.

this was right around the time of the martin luther king holiday. officials at that mosque, the islamic society of boston tell us at that time someone was giving a sermon at the mosque and extolling the virtues of martin luther king junior and saying that mohammad and king were men people should emulate and that was too much for tamerlan tsarnaev according to officials. here's their description of what happened next. >> some people said that he said something to the effect of you can not compare or make a parallel between a prophet and a nonmuslim. some people said he referred to the person that was giving the sermon as a hypocrite. >> reporter: according to too that board member that is a complete violation of etiquette of a mosque. you are not supposed to really talk at all during one of these services.

you are supposed to sit there an pay attention. he says after that the people who were in attendance basically told him to back off and get out, which he did but he kept coming back to friday prayers after that, erin. >> all right. thank you very much, brian todd. get more and more pieces of this put together. the search and the answers for the boston bombing may be found far away in one of russia's most troubled republics dagestan. it is a dangerous region and the epicenter of jihadist recruitment and where the older brother tamerlan tsarnaev stayed for sinx months in a trip last year. nick, i know you spent a lot of time trying to figure out what he did during that visit. what have you learned? >> six months vital in so many ways. we know he came here according to u.s. travel records in january. his aunt who we spoke to this morning said he met up with her in march. so a gap where we don't know of

what he is doing for a few months there. his father came and they joined together in may. witnesses in the street saying he worked with the father at a refurbishing flat apartments in the nearby area. the aunt says he went to chechnya to visit relatives a couple of times. the violence has moved here and focused on dagestan. the key thing ta that they took away that the man that left the united states and perhaps worried in to getting in to drugs had come back a devout muslim. he embraced the faith. considered a pillar in his life. wouldn't look women he wasn't related to in the eye an absolutely devout, pretty much all he talked about said his aunt. >> it is strange to me that he adopted islam and not his father or mother but himself. it is not so strange now days.

the children study islam and teach their parents and that's how it turned out with him. they hadn't prayed before america. nobody taught him. he learned everything himself. at the same time we were happy about it because he didn't start to do drugs or alcohol and adopted the path to islam. >> reporter: they tried to struggle to put together any kind of motive. he did leak from his you tube channel to a video of islamist extremist killed by russian special forces in december. we don't know if they met but we do know his interest in such people were of course will be looked ott at by investigators. erin? >> nick walsh, thank you very much. crucial details coming to light and could be at the center of this while recovering in his hospital bed the youngest of the two brothers, dzhokhar was charged with using a weapon of mass destruction and the white house announced he will not be tried as an enemy combatant. this intensified a debate over how to handle terrorism cases in

this country. today senator lind lindsey gramd them to reconsider this. >> i'm asking them to leave on the table the option if the evidence warrants to designate this individual as an enemy combatant. the ability to have access to this suspect without a lawyer present to gather intelligence about a future attack is absolutely essential to our national security. >> democratic congressman, a member of the house intelligence committee is "outfront." good to have you with us. we know that suspect two has been read his miranda rights so he will not be designated as an enemy combatant but if he had he wouldn't have been intitled to a lawyer or civil trial. and they could have asked questions without a lawyer

present. that may or m.i.a. not be relevant to national security. why did they make the decision not to go for enemy combatant case. did they have so much evidence that they don't need to hide behind enemy combatant? >> i they is part of it. looks like an overwhelming body of evidence. more that that, i think they felt they could get immediate information they needed by the miranda exception, the public safety exception. so they could make sure the public was safe. there doesn't seem to be a constitutional basis for treating an american citizen for acts committed in the united states as an enemy combatant. the quintessential enemy combatant case is a foreigner on a battlefield or elsewhere. the supreme court upheld treating an american, the american taliban captured in afghanistan as an enemy combatant. here on our own soil this is a paradigm case to be treated as a

terrorist and prosecuted within the civilian court system. >> i see your point. people are going to ask the question whether terror has changed. an enemy combatant is a person who planned, authorized, committed or aided in the nine attacks of 2001 or a person who part or substantially supported al qaeda, the taliban or associated forces engaged in hostilities against the united states. if you have groups inspired in chechnya or anywhere else killing american civilian and done by americans, isn't it the term that needs to change rather than the person doesn't fit the term? >> that's a great question. in fact, i think what you are pointing to is that authorization used military force which was drafted in the wake of 9/11 is outdated and doesn't fit the kind of changing threat that we are facing. we have seriously degraded al

qaeda's core but now we are seeing spinoffs and self radicalized cases. and that's going to require a different approach and a different legal basis. simply because the threat environment has changed doesn't mean our constitution is so flexible that we can ignore its provisions. i do think that what we ought to call on the administration to do is come forward with a new structure and to articulate how the rule of law will support protecting the country in this new threat environment. there wasn't a case for treating this brother as an enemy combatant and i think it was very premature for my senate colleagues to call for him to be treated that way. >> congressman, thank you very much. up next the attorney for american wife of tamerlan tsarnaev said she had no knowledge of the attacks. does that add up? and the destructive nature of the pressure cooker bomb and what can be done to stop them? we have a special investigation.

if you are just joining us, i want to update you on the investigation in to the boston marathon bombings. dzhokhar tsarnaev and what he has been telling investigators from his hospital bed. indeed, it turns out he has been communicating with them. we have a live report from boston tonight and drew, pretty interesting. there are significant new details here on what he's telling investigators about why he and his brother apparently did wa they did.

>> reporter: and most importantly, erin, that he is now saying it was just him and his brother, no foreign involvement. no one else here in the united states. of course officials have been telling us that throughout the week. for now a source to jake tapper is saying that dzhokhar communicated that with investigators that in his hospital room that he describes that his brother was the ring leader in all of this. that his brother and he acted out of a religious or political jihad. that somehow they self radicalized virtually over the internet without communicating with anybody else. that would be extremely important in the national security investigation. what has to take place now, as has been taking place, i might add, since one brother was arrested and the other was killed is they have been

checking everything about these two men electronically, who they talked to, what kind of communications they had through e-mail, phone or anybody else to make sure erin that it is just two people involved with this. there are no more plans for any attacks and there are no more people involved. that's what investigators now must do to make sure that this is indeed over. erin? >> it is interesting because even if it is over, while that gives a great sense of relief it opens the door to self radicalization and how incredibly difficult, if not impossible, that sort of thing is to track. there are details in terms of the evidence of what investigators are finding. that was also -- i mean when i was looking at it, that was significant for investigators. >> reporter: it seems like a very, very strong criminal case the surveillance video outlining their exact movements, pre-bombing, the placement of backpacks in the locations where those bombs went off.

dzhokhar walking away from his backpack, if you will, just seconds or so before his bomb exploded and then there is the day, the night of their capture and the shootout in watertown. how tamerlan tsarnaev allegedly told his car jack victim that he's indeed the marathon bomber. he said i did that to the car jack victim who's talked to investigators. then in the dorm room of dzhokhar, they find large pyrotechnic that could supply some of the black powder that may have been used in the explosion and most telling to a layman is the black jacket and the white cap that we saw in those videos. they are saying it looks to be the same kind of wardrobe that was seen in those surveillance videos but that certainly sounds like a very, very strong case

and now, supposedly, you have dzhokhar, the survivor of this, somewhat giving an admission to investigators from his hospital bed that indeed it was he and his brother involved with this. >> certainly seems that way. doesn't seem to be an attempt to cover the tracks at the point. from what we understand from the suspects. thank you to drew griffin. as we know, the fbi is questioning a lot of people in relation to this case. these people -- dzhokhar and tamerlan were not isolated. they had a lot of friends and people their lives and the fbi wants to question the widow of the suspected bomber, catherine russell of tamerlan tsarnaev. they were married in 2010 and authorities search for answers and family and friends are crucial to the investigation. and according to her attorney, though, she didn't know anything about the bombings and was devastated to hear her husband maybe involved. is it more complicated than that, though?

chris lawrence is in north kingston, rhode island, tonight. what do investigators want to hear from catherine russell? >> reporter: erin, federal authorities want to know what, if anything, catherine russell knows about what her husband was doing before the bombing, and what affiliations he may have had other than his younger brother. the attorney told me bottom line she is cooperating with federal authorities and that she didn't know anything about what was going on until she actually saw it on the news. he said she understands why federal authorities want to talk to her. quote, she understands the need for doing it. this is the way the government looks at it and she understands this. it is a threat to national security and she gets that. she's a really good person. very sympathetic to that. katie's just trying to bring up her daughter. that was from the attorney. the daughter he is speaking with is the 2 1/2-year-old little girl that she had with tamerlan.

basically, he says, that the family is a mess. that catherine russell is distraught, crying a lot. he says she feels horrible about what happened to the victims of the boston marathon bombings and also dealing with the loss of her husband and the father of their child. but he says she was in a tough spot before all of this. he says she was raised christian. that she converted to islam after she married tamerlan in 2010. she was very observant. she wore the head scarf but said tamerlan hadn't been working full time so katie russell was basically working up to seven days a week, 70-hours a week and then tamerlan was the one who was staying home to look after the young daughter while she was working. erin? >> thank you very much, chris. two of the bombing suspects sisters live in new jersey and also being investigated by the

fbi. i spent some time there today and met with the man of the town where they live, west, new york, who was with them on friday when they found out that their brother, dzhokhar tsarnaev had been captured. >> i was actually there and it was surreal feeling. i was crying. you can see, as a physician it was terrible. the wailing. they were both hugging each other. >> the two sisters. >> the two sisters were hugging each other. the baby was in their arms and it was surreal. it with was depressing, terrible feeling. >> what did they say? were they totally shocked? >> they were shocked. they were shocked and just crying. they were mentioning god. this is incredible. they were just feeling terrible about the whole situation.

>> could they believe it? we can only imagine what it is like when you find out something like this. some people in the family have been in disbelief they don't think those men could have done this. what did the sisters think? >> continuous crying. i basically said i'm here as the mayor. my concern is your safety. my concern is your health. let us know whatever you need. i'm here to, you know, the same thing with every resident of west new york. >> the mayor also says his relatives are afraid to leave the house. there was a police car stationed outside of the house and they are worried for their safety. the pressure cooker bombs used this the monday marathon attack are underscoring the danger of ieds. they are cheap, easy to transport and tough to find. in an "outfront" investigation we learned how simple it is to build and detonate one of these deadly weapons. at this remote desert testing ground, experts from new mexico

tech replicate and explode bombs used by terrorists. on this day there's a sense of urgency. >> after boston, what are you worried about? could this be the future of domestic terrorists. >> you are always worried about copycats. are more and more people going to use this? >> reporter: this is a pressure cooker bomb, similar to the bombs in boston and we're about to set is it off. >> countdown. >> in the wrong hands, we already know how deadly this bomb can be. and we're not taking any chances. for safety reasons we have had to retreat to this mountain top here. we are now over a quarter mile away from where we left that pressure cooker. but that's still not far enough to avoid flying shrapnel so we are watching from inside of a bunker. >> five, four, three, two, one. that white smoke looks just like it. >> i could feel it up here.

>> the shock wave will travel all the bay. >> down below is the real shock. >> at this point we are looking for fragments. one bomb turned in to thousands of weapons. scattered more than 100 yards. this is part of the pressure cooker now mangled and razor sharp. >> no wonder so many people got hurt. >> instead of nails we filled the pot with nuts from a hardware store. shot out like bullets they pierced plywood. some melted from the heat. >> look at the back of it. >> they can travel, 1,000, 2000 feet a second. >> that's faster than sound. >> they will move faster than the speed of sound. they will get in front of the shock wave and hit you before the pressure wave does. >> you are hit before you hear it. >> that's right. here's what the blast looks like using a high-speed camera. an intense ball of fire, less than 20 feet across. watch the white rings on these desert floor. that's the shock wave.

engineers studying this blast say there's a lesson in here for first responders. let's say i'm a first responder, what do i need to be aware of when i come up on a scene like this? >> there's a lot of shrapnel around. it is hot, sharp. easily cut yourself. there could be unexploded ordinance, parts of the bomb left overthat didn't explode when it was supposed to and that could go off at anytime. >> out of this demonstration there are only words of caution. by the time you hear the boom you could already be hit. awareness of your surroundings could be the only defense. >> david mattingly is live in boston. i find the piece so amazing. when you say you could be hit before you hear it. that means you could be dead before you hear it. this is something soldiers know but nothing that civilians would think about. what surprised you the most about this demonstration? >> just how power. this crude and cheap bomb really

was. the fact it was able to send out whatever pieces of hardware was inside faster than the speed of sound making sure that you would be hit before you hear the sound of the explosion, that is what was truly surprising. we commissioned the experts at new mexico tech to do this demonstration for us. they were telling me that it usually takes less than $100 worth of materials and access to the internet for anyone to possibly try to build one of these. but these experts were careful in the way they were handling this because this was a very, very dangerous device. >> all right. david mattingly thank you very much. $100. that is just -- it's just incredible. stops you dead in your tracks when you think of how little for so much life. authorities stop another terrorist attack. this one on a train between new york and canada. and later, pausing to remember the victims one week later. hi there, mark. welcome back. nice to see you again! hey! i almost didn't recognize you without the suit. well, this is my weekend suit.

we are back now with news of an al qaeda-linked plot to attack the united states. canadian police today arrested two men accused of planning to bomb and derail a passenger train that travels between canada and the united states. now, police tell us tonight the two suspects were getting support from al qaeda in iran. authorities say there's no link to the boston bombing.

paula newton is in ottawa with the latest. paula, how close were they to actually carrying out the attack? >> reporter: erin, police are saying the attack was not imminent at all but say the threat was real that these people wanted to kill people, they wanted to hurt people. they were sensitive about the fact that the attack was not imminent. why? they were listening in on this plot and putting the pieces together, bugging their homes and cell phones to try to figure out what the plot was about. they were not canadian citizens and in the country several months and they were tipped off by the muslim community that they apparently led them to believe these two people were plotting something. they didn't know what and that gave them the tip off to bug them. congressman peter king says this was a train from toronto to new york. that's something that police here will not confirm for us. certainly chilling details about that kind of a mass attack which we know comes out of the play book for al qaeda.
