8:00. thanks for joining us, bye, bye. >> out front next, breaking news, investigators say they have found female dna on a bomb that was detonated in boston. this news comes from the very same day that police spent 90 minutes at the home of tamerlan tsarnaev. the mysterious man is found and speaks. let's go out front.

gld investigators have found female dna on at least one of the bombs used in the attacks. what exactly does that mean? we're going to get right to that along with all the other angles of the story tonight in boston. susan candiotti with the latest on the investigation and what the fbi found at tamerlan's wife's investigation today. a possible link between tamerlan tsarnaev and a known jihadist and a look at how authorities could have prevented the attack and at what cost to america's privacy and freedom. but i want to go to boston first and susan with this breaking news. >> by finding that female dna on one of the pressure cookers, it certainly helps move forward this investigation.

we know that investigators have been looking for any kind of evidence on the remains of the pressure cooker bombs. looking for hair samples, for any dna samples, for finger prints, for example. now we know it has tested positive for dna. we also know that the fbi retrieved a dna sample from tamerlan tsarnaev's widow, catherine russel, at her parents' home in rhode island. now, just because they took a dna sample and even if hers should match, the female dna sample, on the pressure cooker, it doesn't necessarily implicate her or any other particular female in terms of whether they had anything to do with the preparation or the construction of the bomb. >> it means that a female could have come inon at any

time, maybe even before this pressure cooker was put together. a wide range of people. >> if it's not her dna, it could be her daughter's dna or it could belong to somebody else all together. but, certainly, erin, it does move this case forward. >> it certainly does. we're going to find out a lot more. susan said obviously, significant development. but if it is the wife's dna, is it possible she wasn't involved? we're going to talk more about that with a forensic expert in a moment. as susan indicated, fbi investigators spent 90 minutes inside the home of tamerlan tsarnaev's widow, catherine russel. she was at the residence when investigators arrived. >> you saw them, today,remove

something very specific from katie russel's home? >> yes, erin, we saw fbi going in with evidence-gathering equipment. that included a black case that one of these investigators was hugging against her chest when she came out. there was also a clear, plastic sillen dar that looked like a two-liter soda bottle. but this plastic bag that looked like dna samples. dna samples was very clearly written on that bag, erin. >> obviously, everyone is going to be asking a lot of questions about what the significance of that could be in light of our reporting on the dna and the bomb. we know that katie russel left the home with investigators -- or the same time as investigators. she's now returned back. do you know where they went? >> they went to her attorney's office where she was meeting

with federal investigators for about 90 minutes there, as well. >> there are still federal agents stationed outside the house. >> female dna on at least one of the bombs, the breaking news tonight, and that's what authorities are saying as they continue investigating the boston marathon terror attacks. >> out front tonight, dr. larry kobalinsky is an expert and advisor to the state department in the ukraine. good to have you with us, lawrence. >> it's a pleasure. >> let me just ask you, i know there are a variety of scenarios here. but obviously, they are

collecting dna from the wife and now, obviously, female dna on the bomb. she could have come into contact with this and not have anything to do with making it, right? >> that's absolutely correct. we're talking about skin cells. we're talking about touch dna. you leave yourselves and you leave your dna behind. one of the problems with dna, we don't know when the dna got on the object. it could have been a day, a week, it could have been two weeks before anything happened with respect to construction of the bomb. so we can't jump to any conclusions. the good news is we have some information, we must have genetic information about, you know, who came into contact with the bomb or parts of the bomb. we know that dna survives explosions. we were fully expecting to get some sort of information.

i think the surprise is that it's from a fe mail. obviously, it's comparative science. >> so they're obviously looking at the wife, they would have to be, she lived in that apartment. when you talk about dna on a bomb, is there a way for them to know whether the dna on the bomb -- a bomb fragment came from a possible victim or if it's somewhere so embedded in the dna of the bomb, for lack of a better word, would you be able to say this dna was around from someone likely around during the building process as opposed to the victim? >> no, erin, you raise a good point. dna could have been from one of the vick tills. wu, again, we're talking about a comparative science. and we're talking about the source of that dna on the bomb. you need to compare it with something. you need to have some other

profile to make that come parson. but it is certainly possible that it came from one of the victims, as well. you have to interpret what we say. >> now, if the dna ends up being her dna, how do they make a link that she then knew about it and what its purposes were as opposed to for example touching the pressure cooker when her husband took it out of the box and put it on the counter? >> erin, you raise a perfect question there. all we can say is that her dna is associated with the bomb or part of the bomb. how it got there, when it got there, could it have gotten there, certainly of course. >> lawrence, thank you very much. we appreciate you taking the time, as we have reported, one of whom is tamerlan tsarnaev's widow who lived in that small

apartment and very close quarters in the months leading up to the bomb and the days after the bombs explodesed. still to come, a mysterious man named misha. you may have heard of him, he's been accused of radicalizing tamerlan tsarnaev. the one person who has spoken to misha is "out front." >> if you're not doing anything bad, why do you care if they're watching you? and a dramatic rise in female suicide bombers. an investigation into black widows coming up. everyone's retirement dream is different; how we get there is not. we're americans. we work. we plan. ameriprise advisors can help you like they've helped millions of others. to help you retire your way, with confidence. ♪

>> prosecutors are building their case against dzhokhar tsarnaev and relying on a crucial piece of evidence. surveillance cameras. you know there were so many of them around there. while these eyes in the sky have provided key intelligence, there's no question about it, intelligence that led to the suspect's being identified, the security and surveillance comes at what price to americans' privacy? tom foreman is "out front." >> before the brothers reach boylston street, before the bombs and the hunt that followed, could police have been watching them and, frankly, all of us more carefully? that is the centerative fiery debate in washington and the answer is complicated. >> the technology exists. it's just that our constitution protects you from having that put in place against you. >> reporter: the potential technological power available to police is immense. first, more cameras. the number of surveillance cameras has exploded since 9/11.

in chicago alone, american civil liberties union estimates there are around 10,000 private and public surveillance cameras. along with facial recognition software and that could allow police to track many thousands of people every minute. second, mormon toring of communications and travel. if police tapped into our cell phones, computers and gps units, they could collect a wealth of information about almost everything any one of us is doing. and, third, more security on the scene at large events. more searches, more metal detectors, more officers questioning and frisking anyone who might even look like trouble. mind you, aside from the legal restraints on such eaves drop ing, security experts warn making these measures work in a country of 300 million would be tough. think of the sheer volume of data to be processed. >> frankly, law enforcement

doesn't want to capture all of that. most of us are not doing bad things. law enforcement wants to figure out who they need to focus on and who they can just let go. >> reporter: still, the bigger question remains. does freedom from terror have to mean less freedom overall? for "out front," tom foreman, washington. >> it's a big question. it's one after 9/11 this country had to address. now we have to address it again. "out front," matt welch, and ari fleischer. you've been in the middle of this controversy before, obviously. as we all know. 48% of people, according to "the washington post" after the boston bombings worry the government is going to too far. and 41% are afraid our government will not go far enough. if they had more ability to watch over people, they could have stopped these guys from killing and injuring these people to begin with. >> erin, there's a forever strain between liberty and security in our country. and that particularly gets tested at a time when something like boston or after september 11th.

i'm reminded of one of the most beautiful sayings i ever heard at cambridge university in massachusetts. laws are the restraints that make us free, which is an amazing paradox, if you think a restraint can make us free. that's what civil society is. when times are tense and there's a security risk to our country i err on the side of law enforcement. a libertari a. n side we should all listen to. but at the end of the day we aye come down on the side of you need to protect the people, protect the country so you don't get massacred when you walk on to a street. it's also why we have those security cameras up, not to invade our privacy but protect us and keep us free. >> he makes a good argument. when people think about it, they may not want those cameras.

but if it's going to save their life or someone they know or stop a bombing like this, why wouldn't you have them? >> for one, we have this false notion it's a one to one trade-off, balance between liberty and security. if we just take away some of the liberty, the security goes like this. i kind of reject that. if that was true, the most secure, the most surveillance state country in the world would be the most secure. well, east germany wasn't secure. ultimately, it was unstable. it was vulnerable, because you can't suppress freedom that much and get away with it. right? it's not necessarily tension. open societies, open countries tend to be safer and freer at the same time. so, in the case of boston, you can't just have security cameras all over the place run by the government. it's not efficient for one. it relies on central intelligence. so we have to be mindful of

constitutional restraints here. >> hasn't the threat, in a sense, change? you talk about east germany. the threat here has changed, self radicalized, jihadists, hard to find. the world has changed and our constitution is going to have to change. the word privacy isn't even in the constitution, a federal judge noted. abortion discussion for that, but it's not actually in there. >> the world has changed. it's gotten safer. we have less terrorism in this country than we did in the 1970s. there aren't people launching pipe bombs on every street corner in greenwich village anymore. we're not hijacking planes and going to cuba every other weekend. it's actually gotten safer in this country. yes, it's changed. what shouldn't change is the idea that there should be a restraint, something in between the government's desire to do something and an individual's right to walk around free of unreasonable search and seizure. >> let me ask you this. the fbi is saying these bombers

could have learned to build these bombs on line. google, if the company had been forced to tell us that these guys are coming to these kind of websites, we could have found them. i looked up the other day how to build a pipe bomb. the results are limitless. it's unbelievable. i find it shocking they wouldn't have to report that. is it worth saying if you're looking for those kinds of things, google has to tell us? >> no. i don't think we should start limiting what people should do online. the government has a responsibility to keep as accurate a list of potential suspects as possible. their job after september 11th is to work with other agencies. if somebody is on a list for good reason, the fbi should do a good job of surveilling that person all within the rule of law. you have to have a starting point that you suspect somebody is doing something and not a drag net to suspect all just for the simple act of going online. that would go too far. back to your earlier point, we have to remember we're not east germany. totalitarianism versus freedom. freedom is the right side and will win. this needs to be seen on the american continuum. we're not about to become totalitarian, but we do need to be safe.

one reason we don't have planes hijacked anymore to cuba, we have given up our civil liberties and are scanned before we walk in a terminal. it's not a one up, one down. there is a tension. and the fact that we walk through a metal detector to get on a flight is yielding of some liberty for the sake of security. >> all right. thanks very much to both of you. let us know what you think. would you walk through a metal detector at a marathon? would you do it? or is that going too far? thanks to both of you. a manhunt now under way in northern california. police searching for a man suspected of killing an 8-year-old girl. we'll be right back. a manhunt is under way in northern california after an 8-year-old child, a little girl, was found stabbed to death in her home. she was killed saturday while she and her 12-year-old brother were home alone in valley springs, an hour south of sacramento. the brother is not a suspect at this time but are continuing to talk to him, since he was the last person to see his sister alive. out front in california tonight. >> reporter: sheriff's deputies on foot and in patrol cars made their presence seen at jenny lind elementary school where leila fouler, the 8-year-old girl stabbed to death in her home over the weekend, went to school.

>> i'm scared for my kids. for the family. it's horrible. he was friends with her in class, classmates. they sit together at school. things like that don't happen here. >> why don't you tell us about what you have and why. >> i didn't want her to die. >> reporter: leila's mother told cnn via facebook, we are devastated and she was so full of life.

look at our baby girl. she didn't deserve this. police say leila and her 12-year-old brother were home alone saturday when he saw an intruder leaving the house. he then found his sister stabbed, severely wounded. she later died. since then, police have been running down leads, but have no specific suspect. >> we are searching extensively in attics and storage sheds. it is a difficult area to search. it's rural, remote. the grass is tall right now. >> there are empty homes and outbuildings around here. there's a lot of huge rocks where somebody could hide in. >> reporter: authorities have combed the home for evidence. >> we've collected fingerprints during that search and also what we believe to be dna. those prints and that dna will hopefully be processed within the next week. >> michael range lives near the fowlers and heard of the stabbing by a neighbor boy. >> i took my kids inside and locked the doors and waited to hear actually what happened. it's been scary. we've been inside all weekend. >> reporter: a lot of residents feel trapped, pinned down after the mysterious death of leila fowler who would have turned 9 in june. valley springs, california.

>> we'll keep following that story. still to come, more on the breaking news that we told you about at the top of the hour. investigators have found female dna on one of the bombs used in the marathon attack. and then who is misha? we are learning more about the mysterious man authorities believe radicalized tamerlan tsarnaev. the only man who has spoken to misha is next.

rethink possible. i want to get back to breaking news in the boston marathon bombing attacks tonight. authorities are now saying that they found female dna on at least one of the bombs. now, i want to make it very clear at this point, while this could be a significant development, it is not clear whose dna it is and it is not

clear whether it means a woman actually helped to carry out the attacks. investigators obviously are searching for any link. joe johns is in washington tonight with the latest. joe, what does this development mean exactly? >> erin, everything you said is on point. sources tell cnn that, yes, female dna was discovered on a fragment of one of the bombs of the boston marathon. they're obviously trying to figure out whose dna it was. they took dna samples at the home of katherine russell, tamerlan tsarnaev's widow. what could this mean? we don't know. experts we spoke with stress that dna that they found at the location of the bombing could be belong to anyone who came into contact with virtually any of the consumer products used to make the bomb.

so it may well not implicate anyone of anything. it could have ended up on a battery. there was a battery there, a remote control there. obviously, as far as we can tell, there was certainly something on the pressure cooker. there were probably a lot of handlers in the chains of commerce as all these products went to market. it's not to speculate. all we know is that they have dna. they're not sure what it means and it belongs to a female. erin? >> joe johns, thank you very much. as we get ready to go to deb feyerick, forensic expert a few moments ago told me there's a big difference between skin cell dna and blood dna. blood dna could have indicated that this came from a victim. skin cell dna, as joe ind indicated, from someone along the manufacturering line or someone involved in the making of the bomb. a possible link between tamerlan tsarnaev, the older brother, and a jihadist in russia who died in a firefight with police while tamerlan tsarnaev was in the region, right?

>> that's right. what we're learning is that they're looking into the possible link between tamerlan tsarnaev and a young boxer, canadian turned jihadi. he and six others killed in the dagestan region in july 2012, exactly the same time that tamerlan tsarnaev was in the very same region. his body was prepared for burial by an imam july 14th. they believe it was brought down from the mountains and prepared for burial. a few days later, tamerlan left dagestan and went to moscow where he caught a plane to the united states. the time line of this is that tamerlan was actually waiting for his russian passport to arrive. he had applied at an office in dagestan, waiting for the document, the russian passport to arrive and he left without it. and that's what makes it so curious. when he flew into new york, he

did have a passport and his permanent resident card. two documents that he would have to enter the united states. it's curious as to why he would have left that region without his new passport. that's why they're looking at this closely. erin? >> especially if that was extensively the reason why he was going. deborah, investigators are looking for a link between tamerlan and another militant. did he learn how to build these bombs there, was he radicalized there? and now there's another guy, too. >> exactly. the other link is to a man named mahmoud al sunidal. sort of this war lord and islamic extremist who was killed back in may of 2012. so what we see happening here is the creation of the timeline where russian counterterrorism forces are really going after these rebels who are in the

mountains. so you have first the death of mahmoud and whether those two deaths influenced tsarnaev to get out of dagestan is what they're looking at right now. there's been no confirmation that he midwest met specifically with these people, but they are were in the right place at the right time, trying to link him there. >> that could be another crucial link. and another one is this. the mysterious misha. you heard the name by now.

he is said to have influenced tamerlan tsarnaev and reportedly has come forward saying he had no role in the blood shed. his denial comes at the same time the cnn has learned the fbi has interviewed the man, misha, from rhode island about his ties to the tsarnaev family. "out front" now, christian carl. thank you very much for coming on. you caught misha and his family by complete surprise when you went to the home. you described him as a 39-year-old man of american-ukrainian descent. of medium height and has a thin, reddish blond beard. >> thank you very much for having me on rkt erin. it's a great honor. he was a very interesting character. i'm not sure what i was expecting. the man i met certainly did not fit the description, purely superficial terms of an islamic master mind who was manipulating people. he seemed actually rather

agitated and very, very nervous and -- but despite that, he was quite welcoming. his family was very welcoming. and i was struck how much he resembled the physical description from some members of the tsarnaev family, medium height, stocky, reddish-blond hair. and that matched in general terms of the physical description that the tsarnaevs had given of him. >> christian, misha is a common name in russia for mikhael. i know you're talking about the superficial resemblance to the description. did you feel comfortable this is the guy? >> i really did, erin. first of all, i heard about him from some russian-speaking sources in boston that i had found who have not yet spoken to the press.

i'll be writing about them in my next article for the new york review. and when i was talking to them, they were very kind. and they knew a lot about the tsarnaev family. they had associated with the tsarnaevs for many years and they were quite eager to tell their story. as they were telling me their story, misha's name came up and i said that's interesting. did you know him? they said oh, yeah, we knew him quite well. he was hanging around. we didn't -- you know, we thought he was a very nice, harmless guy. we don't understand why the tsarnaevs are saying these things about him. then i asked if they knew his name and they said they did and he lived in rhode island. there's only one person by that name in rhode island. there are not very many armenians who converted to islam. and he confirmed that detail to me when i saw him. again, there's this physical description that matches. when i arrived at the apartment, i almost -- they understood immediately why i was there. i identified myself as a journalist. >> you were able to communicate fully in russian.

i'm correct, right? >> we spoke a lot of the time in russian. sometimes he spoke english. he speaks very good english with a rather pronounced russian accent. his parents, with his parents i spoke almost entirely russian. >> all right. now one thing i want to ask you about -- you had a conversation about how well he knew the family. we've been hearing these different family members saying misha this, misha that, that has led to this outside perception. he never met tsarnaev's family members but obviously the suspect's mother said he was in their home, praying with them. here is what she told our nick peyton walsh. >> when misha visited us, we just kind of -- he just opened our eyes, you know, really wide about islam. he was really -- he was devoted and very good, very nice man. >> so what do you make of that?

he's saying he never really met the family members and she's kind of going into detail about his devotion to islam. >> i have to clarify a little bit. what he told me was that he had not met the uncle. >> okay. >> uncle ruslan and the brother-in-law in kazakhstan, who accused him of radicalizing tamerlan. he definitely knew the mom. he didn't deny that. what he denied is that he had some kind of radicalizing influence on tamerlan. >> when you talk to him about islam and his beliefs in islam, what did you come away with? >> well, i came away with a sense that he was certainly very sincere in his beliefs, but i covered the wars in iraq and afghanistan. i've met a lot of jihadis.

this guy did not give me the impression of being an islamist extremist. his american girlfriend was sitting there on the couch in her shorts. admittedly, i surprised him on a sunday at home, but she was not wearing hijab. she was not, in any way, kind of confined from speaking with me. look, erin, this is a very superficial impression, i completely admit it. i have to emphasize that this was not a formal sit-down interview. i surprised these people. they were very upset and agitated and i tried to ask a lot of questions about all of the things we want to know the answers to. and they just didn't want to go there. so, the story is not over. there were a lot of questions we still have to answer. >> but at least you have a sense of this person better than anyone else. we appreciate you sharing it with us. thanks, christian. >> thanks. authorities tracing the suspect's activities in the weeks before the bombing are now focusing on the tsarnaev brother's home in cambridge, that small apartment we've been talking about. if, as suspected, they planned the bombings in that apartment, did they leave behind crucial evidence as to where or from whom the explosives came from? paula newton is "out front."

>> reporter: the flags are lowered even on st the place the tsarnaevs called home. sobering reminder that this isn't over. there is still much to learn about the suspected bombers and their motives. >> you know, my window looks over their bedroom window. >> reporter: for mary silverman, the mystery started when she wasn't allowed to go home. >> law enforcement said you can't go in. i said, why can't i go into my house? he said we're afraid of explosives and then i was thinking that they made the explosives inside the house. >> reporter: silverman is terrifyingly close to where the suspects could have put together their plan and their bomb. >> blinds are always drawn over there? >> always. never had them open. seemed odd to me. >> reporter: the fbi has confirmed to cnn they are still on the hunt for explosives and still questioning people. a short distance away -- >> i can see a bullet on the left of that window in the

second floor. >> and you didn't even know? >> no, we didn't notice that. there was so much shooting. >> reporter: she shows me where the stray bullet pierced through her sitting room. >> right through this wall. >> through that wall and then buried in a sofa cushion. police took the bullet away, telling her it was one of 69 stray bullets that hit homes and cars as police battled their way through a bloody shootout with dzhokhar and tamerlan tsarnaev. you can still see the damage from that kind of fire power here. they were pinned down from police and still lobbying explosives at them. there are so many questions in this investigation. where did they get the bombing material? how and where did they put those bombs together and, crucially, did they have any help? >> really, really scared when i heard explosions. >> reporter: she says she left,

never imagining it would follow her to her new home. she has the same thought that must be nagging at police. >> i think it's really hard for two boys to plan all that on their own. >> reporter: you think they must have had help? >> i believe so. >> now, paula, do you know what investigators have found so far in terms of evidence from the explosives? that is, quote, unquote, the holy grail for them right now. >> reporter: two very important locations. one not far from here where the bombs went off. that shootout on laurel street. erin, the fbi made very clear to me, look, finding out where those explosives come from are a huge part of this investigation.

it can point to whether or not there are other people involved in this plot. is there some kind of bombmaker out there, either in the united states or perhaps even in russia that they don't know about? that bombing signature, erin, is so crucial at this point. they, in terms of executing any search warrants right now have not found the missing link to tell them definitively where the bombs were made. and in trying to re-create these things, they don't work that often. very often you have to test them. that's part of that investigation, too. >> the testing and dna they found there as well. thanks very much to paula. dramatic rise in female suicide bombers. of course, as you know, the mother, tsarnaev brother's mother, quote, unquote, a person of interest. we'll bring you our investigation into the black widow, women responsible for the most violent and deadly terror attacks in the world. trapping thousands of workers, the rescue team makes a dramatic decision. it helps you see if you have too much coverage or not enough, making it easier to get what you need.

one of the alleged boston bombers and his mother were

as the boston bombing investigation focuses on the

tsarnaev brothers posz terror ya, one disturbing claim hborinc is the rise of women suicide bombers. they actually have a name for them there. they're called black widows. named that way because some are wives of insurgence killed by government forces who, themselves, take up the cause and become suicide bombers. nick robertson is in dagestan with an "out front" investigation. >> in dagestan, an inferno. moments earlier, a female suicide bomber noechb here as a black widow detonated a bomb at a police check point. minutes later, another blast. the following day revealed the horror. the black widow's brother driving a car bomb blew this truck apart. callous timing killing emergency service workers just as they arrived to put out the flames.

a brutal conflict spilling over from neighboring chechnya as tamerlan tsarnaev visited his parenthere last year. >> this is the same spot here. according to local journalists, for a while, police were too afraid to patrol. >> russel kadye, v, tells me russian authorities are handling the female bombers all wrong. >> it is a problem that's been around over a decade. involving wives of rebel forces. >> when a woman's husband is dead, she has no rights. she can't have a lover or boyfriend. she can't make any decisions. that's why, if she's rely joyce, she becomes an easy target for suicide recruiters. >> finally, in 2002, they took

more than 800 hostages in one of the moscow's principle theaters. it was one of the russian's deadliest terror attack and the so-called black widow ready to roll. at the time, two female suicide attackers attacked moscow subway. one of the attackers 17-year-old jeanette fit the black widow profile perfectly. her husband, a rebel leader had been killed by security forces a few months earlier. >> also represents a changing face of the black widows. she's from here in dagestan, not neighboring chechnya, like so many of the black widows before her.

normal black widow age. somebody what's relatively vulnerable in society. and tsarnaev doesn't really come across as somebody whoa's vulnerable. but, certainly, she has come across with strong opinions. and it is men like that in their past, erin. >> are women suicide bombers more effective than men? >> they certainly create a lot of problems here. there's an ability there to sort of come into a situation where men are at a police check point and they wouldn't suspect a woman, necessarily. that's why it creates such terror for the security forces. women are ignored. they're not looked at as potential attackers. that's one of the reasons why

they're an effective toll for the rebels, erin. >> nick, thank you very much.
