for now, however, i'll settle for fixing my headache. that hurt. here in boston, two bombs, two brothers accused of turning the marathon into chaos and carnage. now we follow the trail of terror from the boston suburbs to a war-torn part of russia investigating who the suspects were, how the deadly plan took place and crucially what turned a pair of striving immigrants into alleged killers. drew griffin begins our special report, "boston terror behind the bombings." [ explosion ]

>> from the moment two bombs exploded at the finish of the boston marathon. >> oh, my good, my god. >> another race began to catch the perpetrators of the deadly attack. >> today we are enlisting the public's help. we are releasing photos of these two suspects. >> reporter: april 18, 5:21 p.m., these two men later identified at 26-year-old tamerlan tsarnaev and his 19-year-old brother dzhokhar become the most hunted fugitives in america, their pictures splashed across every tv, phone and pick poor across the country. somebody knows these guys as friends, co-workers or family members of the suspects. >> reporter: less than five hours after the images are released, the suspects resurface with deadly consequences. at 10 20k p.m. an m.i.t. police officer iounds f sho dead in

his patrol car. >> just blocks away around 11:00 p.m. a 26-year-old chinese entrepreneur living in boston is carjacked at gunpoint in his mercedes suv by two men claiming to be the boston bombers. "boston globe" reporter erik moskowitz interviewed the anonymous carjacking victim named danny about his ordeal. >> along the way he hears them talk about manhattan. they ask him about whether his car could go to new york. >> reporter: suspects stop at an atm to withdraw $8,900 cash using their hostages bank card and password. back in the car, the victim's cell phone rings. it's his roommate asking him where he is. >> tomorrowian says, pick up the phone, if you say anything in chinese i'll kill you because if you speak in chinese you may be calling for help. >> reporter: en route to the expressway they make a crucial pit stop. >> heading towards interstate 95 they realize they need gas. they pull up to a gas station on

the charles river in cambridge. the younger brother gets out with danny's credit card to get gas. moments later he knocks on the window and says cash only. he then has to go into the food mart. that leaves just danny and tomorrowian in the front two seats. tomorrowian has the gun down in the pocket and is fiddling with the gps. >> and danny realizes that's his to im. >> reporter: while one brother is inside paying for the gas, the carjacking victim bolts from the suv, sprinting to the gas station across the street. he fell. he collapsed here. he fell right here and appealed to me, please, please call the police. there are people out there who want to call me. people who want to make sure i die. they have guns with them and they have a bomb with them. >> reporter: in his rush to escape the carjacking victim leaves his cell phone in the stolen suv. police track its signal to watertown where andrew kitsenberg is hanging out in his

living room watching the hockey game. >> i heard pops outside and so i ran to the window, and when i went to the window i saw two shooters behind an suv. >> the two brothers stopped, got out of the vehicles, immediately started shooting at my officer. >> reporter: without provocation. >> right. they took the gun fight to us. >> reporter: kitsenberg runs to his bedroom, takes out his iphone and starts taping photos of the surreal scene unfolding outside his window. >> there's a serious gun fight going on. the second person on the scene one of my sergeants, he pulled up, and he immediately gets at least one shot right through his windshield, and he decides to put the car in gear and lets it roll down the street while he's able to get out and take up a position so he's a little bit safer. >> at some point it's more than just guns, right? >> right. >> reporter: it's explosive devices. >> one of them goes to pop the drunk of one of the vehicles and hurls something at our officers.

>> reporter: did you see the bombs being thrown? >> i did. i saw the explosives being thrown and then they -- i could see them reaching down into backpacks. i actually saw them take out the pressure cooker bomb and put it right at their feet >> reporter: brothers had another bomb just like the ones they are suspected of using at the marathon. >> i actually saw a spark from the bomb, and that's when i immediately hit the ground. i could feel it. i could feel it shake the house. at that point one of the shooters actually started charging the officers, running down the street still firing his weapon. >> and they are literally about ten feet away from each other exchanging gunfire, and then he runs out of ammunition, the bad guy, one of my overs is able to tackle him and put him to the ground. >> i looked back up, and the other brother got back into the car, and he had turned it around in the street and started accelerating up -- up laurel street towards the police, towards the vehicles, basically

flooring it. >> somebody at the last minute yelled get out of way, and they dove out of the way as he came roaring through and ran over his >> as tamerlan lies dying in the street 19 tsarnaev drives straight through a police barricade and escapes. >> the car that he abandoned a little further down the street there was blood in that vehicle, so we knew he was wounded. we just didn't know how bad. >> reporter: wounded and on the lose. at dawn on friday an entire region is put on lockdown as a convoy of law enforcement personnel and equipment rolls into watertown. >> we're asking people to shelter in place, ihewords, to their doors locked. >> during the day friday, door-to-door, room-to-room searches turn up empty, and by 6:00 p.m. bad news. >> we do not have an

apprehension of our suspect this afternoon. >> the voluntary stay-at-home order is lifted. >> we are asking the public to remain vigilant. >> after a day inside, watertown resident dave henneberry walks out to get some fresh air and notices something amis wh the cover boat. he took a closer look. >> i got i think three steps up the ladder, and i was -- i rolled it up, and can i see through now the shrink wrap. i didn't expect to see anything, and i look in the boat over here, i l the floor, and i see blood. >> what happens next is a blur. >> well, i know i took three steps up the ladder. i don't remember stepping down off the ladder. >> in an instant special law enforcement units, including s.w.a.t. teams and helicopters with infrared cameras swoop in.

shots are fired. police are certain their man is inside henneberry's boat named the "slipaway two." hostage negotiators attempt to talk dzhokhar into sundering. >> we know you're bleeding. >> i believe they tried numerous flash bang grenades. they tried to gas him out of the boat. just wasn't work. >> a s.w.a.t. team approaches. he was sitting on the edge of the boat with one leg hanging over the side. >> they tell our anderson cooper about the tense standoff. >> you could see one hand was clear of any weapon, but each time he went back the other way his hand went down inside the boat out of our view, and each time he did that, we had to assume that he was reaching for either a weapon, a firearm or some type of explosive ignition device to try to draw us in and then take us out in a suicide-type manner.

we got close enough that at one point where both of his hands were up we could see there were no weapons, no ignition devices. we broke away from the shield protective cover and just rushed him. we put hands on him, grabbed him and pulled him off the boat and down on to the ground and got him over to where the medics are and the federal agents who were taking him into custody. >> just before 9:00 p.m. it's over, a bloodied, seriously wounded and unarmed dzhokhar tsarnaev is taken alive. coming up, chris lawrence on the trail of terror and what could have triggered the deadly bombings. tate, where cutting taxes for families and businesses is our business. we've reduced taxes and lowered costs to save businesses more than two billion dollars to grow jobs, cut middle class income taxes to the lowest rate in sixty years, and we're creating tax free zones for business startups.

him. if you went up to him, he'd talk to you right back and he was very friendly. >> were there any clues of the violence to come. >> they never expressed any desires to harm people. they did respect life at one point. they were friendly. >> after high school tamerlan attended bunker hill community college studying accounting, until 2008 when he left college, but he continued to pursue his dream. >> how you doing? >> good. >> boxy trainer eddie bishop met tamerlan at a tournament. >> he was a fight their had a lot of skill and a lot of ability. >> but bishop questioned whether tamerlan could ever become a boxing champ. >> but i think he had all the skill, but he lacked the heart, the fundamental ingredient to make you a champion. >> the family is from the came first and then later his brothers and sisters joined the

family. before coming to the united states, tamerlan's father coached him in boxing so he was already on his way to becoming an experienced fighter. by 2009 tamerlan was boxing in the golden gloves tournament in salt lake city, utah. fellow boxer julian pollard roomed with tamerlan and remembered his swagger and sense of style. >> he stood out. and that was kind of the perception i got, flashy, confident, maybe cocky. i guess he backed it up in the ring. he could fight. he could punch. he could put a guy out. when the time was right if he had a big punch in him and the opening was there, he could finish the guy. >> that ferocity apparently carried over outside the boxing ring. he was arrested that same year for slapping his girlfriend in the face during a fight over another woman. the following year, 2010, he married katherine russell, a

suffolk university student he met in a nightclub and had dated on and off at several years. she converted to islam. pollard saw him again that year at another boxing tournament in local, massachusetts, but he didn't seem the same. >> in 2009 just a flashier guy, sharp dresser, like kind of carried himself with a lot of confidence and then the next year seemed like a humbler guy, dressed a lot more conservative, kind of like came to the fight like we all did, hoodie, jeans. >> he also seemed more devoted to his muslim ith. >> h didn't talk that much about his faith to me until like the next year i saw him at the tournament. it was obvious that it was a bigger part of his life. he felt like the immediate need to share with me. he was really, you know, seemed like happy about where he was with his faith.

>> once i was told, momma, you know, it's the right religion. >>tamerlan's mother witnessed his transformation. >> i would like for you to be covered because islam is requiring for women to be covered, so i said it was really like a little not expected aspect, so i said give me some time, you know, tamerlan. >> last year tamerlan traveled back to his homeland, a region of russia rocked by ethnic violence and islamic extremism. when he returned to the united states six months later, he became more outspoken about his muslim faith. at the islamic society of boston cambridge mosque, tamerlan stood up during the sermon and challenged the preacher in two separate public outbursts, one last november and another in january of this year. >> so when the person who was

giving the sermon began to talk about dr. martin luther king, this man got up and objected. you know, he raised his voice which is against the etiquette of the sermon, and people objected to it, and -- and some people might have even asked him to leave, you know, the mosque, if he didn't, you know, like what he was hearing. >> but there were no indications that tamerlan or younger brother dzhokhar could be dangerous. >> cared but, cared about people around them and they cared for other people making great choices and creating opportunities for themselves like they were trying to do for each other and for themselves also. it just doesn't make sense. >> tamerlan's high school friend louis vazquez later coached dzhokhar in soccer at the cambrdige rindge and latin school. >> these two guys had leadership traits, one was a leader of the family and cared for them and the other was a social leader among his friends an his team.

he was co-captain of the wrestling team, little brother. >> dzhokhar got a $2,500 academic scholarship and enrolled at the university of massachusetts dartmouth. on september 11th, 2012. >> would you please stand, raise your right hand. >> an ironic date in retrospect. he took the oath to become a u.s. citizen. zach betancourt went to college with certificatary. >> acted america. >> a very quiet kid, extremely smart. classmates always asked him for help. he'd help all the time. he wasn't a trouble-maker. >> i thought he was like -- he was a good kid, honestly. seemed like a good kid, at least every time i saw him. i like thought he was a nice person. >> those who thought they knew the brothers, from high school, college, from boxing, now realize they never really knew them at all.

the two brothers, outwardly so different, on april 15th are accused of acting together to bomb the boston marathon. incredibly just days after the bombings dzhokhar was spotted back on campus, betancourt saw him at the gym. >> we talked about the bombing for five minutes. seemed tired and off. i asked him how he was doing. hadn't been doing much lately. i said yeah, whatever i was talking about iraq and afghanistan and how craze they was happening, and he said tragedies happen, man. these things happen around the world, like toys crazy. >> for julian pollard he hadn't thought much of his former boxing buddy until last week. that's when he remember that had he had kept tamerlan's number. >> i forgot it was in the phone until i saw the picture on the news and i hit the "t" and sure

enough his name was right there, and that was like, wow. it's definitely this dude. >> but were there other clues in his past? coming up, the russian connection. nick payton walsh investigates what tamerlan was doing on his trip back to his homeland.

the north caucasus, a region ravaged by here's of violence and bloodshed, the tsarnaev family is originally from here, but they left for a better life in the united states. tamerlan tsarnaev returned to this part of the world last year for a six-month visit that's now raising a lot of questions. >> who did he meet with over there, and what did he sflern what did he do? did he become part of a sell? did he get training in how to assemble explosives? did he receive money, encouragement, funding, direct support, come back to the u.s. and attack? and those are things that i don't think we'll ever know. >> what we do know is that in

january of 2012 tamerlan left the united states on a flight bound for moscow. he made his way to dagestan, a russian republic, next to his family's ancestral homoland chechnya, today also a part of russia. >> translator: he could radiate light and warmth. >> his extended family in dagestan welcomed him warmly. >> he smiled a lot, and i asked him is this your customary american smile? he was more of an american. >> much of what tamerlan tsarnaev did here remains a mystery. we know he stayed for some weeks here at his parent's home, keeping mostly to family and friends, helping his father out in his businesses around town and often sleeping in. the tsarnaev family is part of the chechen community here. like many other chechens displaced from their homeland.

after the second world war, tens of thousands of chechens perished in a mass deportation order by josef stalin. in the 1990s, chechens fought and won a bloody war for independence from russia. it was during this violence that the younger tsarnaev brother dzhokhar was born and given the name of a chechen leader. >> it's a sure side of chechen patriotism in the family that in 1939 they called their little son dzhokhar after doakary dudayev who was the pro-independence representative. >> chechen independence wouldn't last. the war would kill thousands and chechen extremists would range a campaign of terror across russia, killing 186 children at a school in beslan and more than 100 theater-goers in moscow. the tsarnaev family escaped the violence in the region by making their way to the u.s. >> he would tell me that he was

from chech n. >> luis vasquez was friends with tamerlan in high school. >> that's where he's from. that's where he told me he had struggled. he didn't really elaborate. >> there's a whole generation of chechens who grew up with their families being displaced, relatives being killed and so on. >> thomas devaal has studied and written about the region. >> for most people that's a traumatic experiment, but obviously for a small minority, this is something that is in their dna that drives them. >> and like many displaced chechens, tamerlan may have struggled to fit in. chechnya is still home to militant separatist groups, and the home tamerlan's father grew up in has been destroyed by war. relatives still live here. tamerlan traveled here during his trip last year. >> translator: he came to see me. we talked. i said come here, guy. are you studying, i asked?

i'm stud eliying, he said. there was nothing criminal about him. >> there,region has also seen a growth in extremism becoming more anti-western and anti-american. >> if you're a young jihadist from this region you sort of blame russia as the evil empire that attacked and oppressed you and also the west basically did nothing to intervene when russia was -- was bombing chechnya. >> it's not known if tamerlan met with any extremists during his visit to chechnya. on his youtube page in a play list called "terrorism" there was a link to this video of a smalltime militant abu dujan. abu dujan and tamerlan were in chechnya. he rain a training camp in the

woods and made this video of how to make homemade explosives and use a cell phone as a detonator and said the local police chief they trained foreigners. >> what did the foreigners learn in the woods? >> translator: i can't talk about the number of foreigners, but they met to exchange their banded experience. >> he said the militants train chechen men who live in other countries. >> there are reports that dujan was observed at the mosque and he was observed meeting tsarnaev. do you know this? >> translator: i really can't answer this. for different reasons i can't answer. you understand me? >> did abu dujan and tamerlan meet? we don't know. this past december abu dujan and other militants were killed when russian special forces hit their hideout. >> maybe he's a hero of the brother. maybe he isn't, but tamerlan watches these videos and then this individual gets killed. now logic would tell you, well,

who would you be mad at? runners in the boston marathon? what did they have to do it? would you be mad at the united states? what did the u.s. have to do with it? >> no one will ever know, but we do know on his last visit to dagestan tamerlan's family noticed a change in him. >> translator: we were happy that he didn't become a drug addict, he didn't become an alcoholic. he was on the path of islam. >> the family says during his time here tamerlan would often visit the central mosque behind me for friday prayers as well as other mosques across this town telling his family how central islam was to his life and that it was a religion of peace. that's why she doesn't believe that tamerlan and dzhokhar could have bombed the boston marathon >> translator: in islam killing a non-muslim is against the law of humanity and killing a muslim is like --

>> the aunt, says the mother, was in shock when she saw her son's faces flashed across television screens here. >>. >> translator: superdat grabbed the television screen shouting it cannot be. it cannot be. >> she can't believe that her sons are responsible. >> i really feel sorry for all of them, really feel sorry for all of them but i do not want to believe that that were my sons, objection and i don't believe. i don't believe. >> the people investigating boston, they say that tamerlan's faith, drove him, what they say he did in boston. >> i don't think so. i don't think so. i don't think that tamerlan did this. i don't think that faith would

bring him into it. >> thursday the parents held a press conference. they are helping with the investigation. both were interviewed earlier by u.s. authorities. >> translator: they asked about our children, how did they live? what did they do? what were their interests? >> coming up, the investigation. drew griffin on the question everyone is asking. was anyone else involved? watch out for myself. with so much noise about health care... i tuned it all out. with unitedhealthcare, i get information that matters... my individual health profile. not random statistics. they even reward me for addressing my health risks. so i'm doing fine... but she's still going to give me a heart attack. we're more than 78,000 people looking out for more than 70 million americans. that's health in numbers. unitedhealthcare.

say a prayer. >> questions the whole nation is aski asking. why would the tsarnaev brothers do it? how did they do it, and most importantly who might have helped them? >> what they want to do is ensure that there are no other ties to any other groups that might try to follow up with this or plan something. >> julia kyyem is a former assistant secretary to homestand security. >> the other piece is building a strong case and making sure that case doesn't fall apart. that's why the indictment released this week was very, very careful to say, look, we know he used weapons of mass destruction. we know he killed people, and that's enough to give him the

death penalty. >> to build the case and find the answers hundreds of federal investigators are now working around the clock, digging through debris, analyzing bits of bombs in one of the nation's largest terrorist investigations since 9/11. neighborhoods like this one across boston are being visited by the fbi. this man says five fbi agents showed up at his door to question his son about tweets sent to the younger brother, and on the college campus where dzhokhar went to school, friends there tell cnn they, too, have been visited by the fbi. >> up next breaking news. >> we'll hear about the terrifying ride through boston. >> there is a lot of news. >> leads are still pouring in, and new details emerging daily. >> breaking news on the boston bombing. >> our attorneys say she knew nothing about what her husband was allegedly planning. >> massachusetts gas station manager is now speaking out.

>> among the leads, details on the bombs used by the tsarnaev brothers, bombs that started with ordinary pressure cookers bought at a boston department store. while deadly the bombs were simple and cheap, packed with nails and ball bearings to cause maximum carnage. >> all of the equipment, all of the supplies involved in the boston bombings was probably under $100. >> and where would two brothers in boston learn how to take a pressure cooker like this and headache it into a bomb like that? right here. of course it's on the internet. >> striking similarity between the boston devices and a recipe which who is put out by "inspire" magazine in the summer 2010. how to build a bomb in your mom's kitchen. >> paul cruikshank is a terrorism expert for cnn. >> pressure cookers were used,

esexplosionive schlepp until was used, a low -- grade explosive powder was used, but also very specific stuff like the fact that "inspire" magazine told followers that they should glue shrapnel inside the pressure cookers. now that's what was done in boston. >> published by al qaeda in the arabian peninsula in english, the magazine was started by anwar al awlaki, the yemeni cleric who was killed by a u.s. drone strike. cruikshank has been tracking al qaeda and this mag zone for years. he says investigators are looking closely at whether the brothers tsarnaev got their bomb recipe here. that could have larger implications. >> one of the largest concerns of western counterterrorism officials is that "inspire" magazine is still publishing new issues. in an issue that was puttous receipt entally, the magazine stated we are publishing

america's worst nightmare. >> as investigators sift through evidence, the bits of bombs found blown across the crime scene should yield other clues, too. >> what were the components used in creating these devices? coupled with that you're going to have a -- an investigation or laboratory sciences working on things like fingerprints, hair and fibers that may be included in there, and also tool markings. >> ray lopez is a former fbi explosives expert. >> these things were made with tools so there's going to be a -- look for tool marks that are left after these things were done, and that's going to be matched to any tools that they could fine at any of the search sites that investigators are working at. >> officials say now at least one of the bombs was detonated with a remote-controlled device similar to those used to control toy cars. federal investigators must now also ask themselves hard questions, like did they drop

the ball with tamerlan tsarnaev? two times the russian government approached the u.s. with concerns about the older brother who later traveled to chechnya. upon his return to the u.s. tamerlan posted this video showing clear extremist tendencies. >> what did he do when he went back for six months? did he sit in his aunt and uncle's home for six months, or was he doing something else, and when he came back to this country, why didn't it ring a bell with the fbi intelligence unit that he should be checked out and vetted again? >> the fbi has told officials the bureau looked into the older brother in 2011 and found no red flags. the cia was also approached by the russians with similar concerns about tamerlan. questions were also raised by

officials about the tsarnaev's mother. both she and the older brother's names were add ed ed to a terro identity database but the investigations seemed to have gone nowhere. was tamerlan tsarnaev radicalized overseas. maybe so, but his uncle said tamerlan's views more than likely came from someone in the u.s. >> i heard that talking, where that might be coming, from and he said, oh, yeah, there is such a thing. there's a person, sort of some new convert into islam. >> that new convert, a muslim extremist right here in the boston area. >> he said this boston, he took his brain, just brainwashed him completely. tamerlan is off now. there's any obedience and respect to his own father. >> the uncle says tamerlan told him he quit listening to music and got very conservative after

talking to the extremist whose name was misha. tamerlan's mother said misha was a good influence on her son. >> 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. >> dzhokhar tsarnaev said they were self-radicalized jihadists inspired in part by the u.s. wars in afghanistan and iraq. late this week new york officials had their own news about the bombers. >> last night we were informed by the fbi that the surviving attacker revealed that new york city was next on their list of targets.

>> the official said tsarnaev indicated that the brothers intended to take their remaining explosives and blow them up in times square. should investigators believe the brothers plotted and carried out the act on their own? still more questions. few clear answers. we may never know who tamerlan met with overseas or what happened to him, but we do know this. he came back a changed man. >> we just had a young person who went to russia and chechnya who blew people up in boston so he didn't stay where he went but he learned something where he went and he came back with a willingness to kill people. >> coming up, how close were you to the second explosion? >> i was right in front of it. >> anderson cooper, finding boston strong. welcome to the new new york state, where cutting taxes for families and businesses is our business. we've reduced taxes and lowered costs to save businesses more than two billion dollars to grow jobs,

he said we've got to get out of here or something like that and i sat up and said i couldn't move. oh, my gosh, my foot, there's something wrong with my foot and he lifted up my leg and started screaming bloody murder. it was really bad. >> what did you realized what had happened to your foot? >> i went into survival mode. >> she couldn't lose her foot because adrian is a dance instructor. it's her passion, her life. and even as she was wheeled into the operating room adrian remained optimistic. when she awoke she remembers feeling her toes. >> when did you realize you didn't have a -- >> i woke up and my parents were there and i hugged them and kissed them and i said mom can you step me, i feel like my foot is falling asleep because it feels like my ankle is falling off of the pillow and my foot is

half on and i realized now that wan phantom pain and she locked at me and said you don't have a foot, your foot is gone, and i just lost it. it's really hard to hear. >> you're determined to dance again. >> i am, yeah. >> dancing is really important to you. >> it is so important to me. it's my life. >> you're incredibly optimistic. >> i try and stay on the positive side. i can either stay in bed and cry and be really upset and i do have moments of that, but -- or i can say i'm going to, you know, run the marathon next year and conquer and be good. i mean, i would never let one of my students come in and say, oh, well, i can't do this anymore because i hurt my arm or i lost my leg, or if they came in with a prosthetic. i would say i'll teach you, that's fine. we'll make that work, and i would be nothing to them if i didn't accept that challenge for myself. >> and you want to run the race next year? >> i do.

i can't believe i said that. i'm only 32. i don't want this to be the end, so whether it's running the marathon or walking the marathon or crawling the marathon and being the last one across i'm okay with that. i didn't say i'd win it, but i -- i am defiant, and i want to -- i want to come out stronger. >> stronger, boston stronger. just like the city where a first pitch signals a new start, like the city that's rebuilding, rebounding, like the city that terror couldn't stop. >> we are one boston. no adversity, no challenge, nothing can tear down the resilience and the heart of this city and its people.
