venturing thousands of miles where tv news cameras have never been. >> like to think of it as paradise lost and fun. >> places teaming with life. it's on land and in the sea. >> coming in. >> could this magical spot hold the secret to help saving the planet. >> what's happening is really an sos signal. we have to do something. >> but first richard engle with an investigation. the terrorist that grew up next door. >> can i talk to you for a minute? >> when did you learn he had gone to syria to join isis? >> right now. >> you din know until right now. >> americans that joined isis. tonight we reveal their identities. >> there's 15 names here. >> an aspiring doctor, a valedictorian. her husband, their baby. how do these young americans become terrorists. >> beheading and the brutality. do you think the boy you grew up with was capable of doing that

kind of thing? >> yes, in an instant. >> the exclusive story right now on assignment. good evening from the nbc newsroom in new york and welcome to on assignment. we begin tonight with an nbc news investigation into the enemy within. americans who left this country to join isis. tonight for the first time we reveal who they are. richard engle reports. two months ago in this small border town in turkey we met a man that said it was an isis defector. he handed us a thumb drive with thousands of isis fighters. it was a treasure trove of information verified by agencies. of all the thaws of names we focused on 15 because they come from right here in the united states. >> these american isis fighters are for the most part the sons of immigrant parents who came to this country to find the

american dream. and they did. their sons grew nup this country. went to school here. had friends and ambitions but they left it all behind to join a terrorist group. why? are there more? and what did law enforcement miss? >> we asked the retired fbi agent to join our investigation. >> this is mona. >> how are you? >> he spent much of his 20 year career tracking radical islamists. >> it's not the most sophisticated crime lab you've seen in the world but these are the documents. >> the documents contain some clues about these young men. >> here's omar. >> he was a student at the university of north texas. and then he signed up to be a suicide attacker. he went to high school in suburban minneapolis. alberto, a convert to islam from

gilroy, california is seen here inside syria. >> the vast majority say i want to be a fighter but this one said i want to be a suicide bomber so he doesn't want to come back. >> but of all the names on the list, two americans stood out because they appeared to arrive in syria on the same day. one from california and one from ohio. he suggested we start with his family. >> my theory was always there is no way your kid will change from normal person to a jihadi suicide bomber and no one notice any difference. >> on a small suburban street outside of columbus we found his parents home. >> can i talk to you for a minute? you don't want to talk to me? >> well he clearly didn't want to speak. get lost is what he said. he said he was going to call the

police. >> off camera, his father told us he brought his children to america from bangladesh 16 years ago and has at times worked two jobs to support the family. he says he hasn't heard from him in two years and disavows what he has done. >> meanwhile our team tracked down this video of him. >> you looked at him and he's such an out going kid. >> he was one of his best friends in high school. >> he was an exceptional student. >> he wanted to go to harvard? >> yes. he wanted to be a doctor. he wanted to help people. >> in this video about an aquarium project he comes across as a typical teen. smart, even a little geeky. >> we tried things like adding nutrients, testing ph, nitrate, et cetera. but in his junior year he started to slip. >> stopped showing up to class. he was dodging class. >> and then before graduation, rasal disappeared.

>> he was off the radar. he was gone. >> were you worried? >> of course. yeah. everyone was worried. >> then about a year later in november 2014 phil suddenly got a text message from rasal over skype. >> he's acting mysterious. >> completely out of character. >> at one stage he writes and says the fbi might come knocking on your door. >> at that point i was like what did you do? >> what rasal had done was unthinkable. he joined a terrorist organization and was already in syria. but he didn't tell phil that. he did tell him who had guided him on his path. >> i hate to make assumptions but i believe because that's what he specifically stated he talked to his sister and that's how he got into islam. so he had a sister that played a key role. here she is at 16 in an ohio public television video.

>> it's harvest time and i haven't had this kind of experience before. >> she was also a hard working high achieving student. she graduated as a valedictorian but a close friend of hers told us that she became increasingly religious and distant and got married soon after graduation. her husband, joffery khan. it turns out zakia was the missing link. her husband travelled to syria with her little brother. a picture was starting to emerge. >> what seems to be most mysterious is this connection. how did she link up with joffery. >> so we headed to california where joffery grew up in a million dollar home in pal palo alto. our first stop there was a building where his father runs a medical marketing company. >> i'm richard engle from nbc

news. we have tried to call you a few times. >> yes. >> can i talk to you for a minute? >> many of the family members we approach for this story didn't want to appear on camera for fear of a backlash. off camera joffery's father that came here from pakistan at a young age told us what he said he told the fbi. he hasn't spoken to his son in nearly two years. we found this youtube video of joffery goofing around with his cousin. that cousin agreed to meet with us in the park where he and joffery used to hang out. >> no one else really was that close to me as joffery was. >> he says joffery was into rap music, marijuana and the internet until he started watching propaganda videos. >> he was getting angry and he said we're surrounded by a bunch of sinful people and we should move to a muslim country. >> he was getting more angry. >> more hateful toward americans. >> it was around that time that

joffery met and quickly married zakia. >> how did they meet? >> online. on a dating website. >> and was she religious at the time? >> she was too. she also covered her face. >> the newlyweds zakia and squr joffery settled in ohio and she enrolled at ohio state university. they chose to move into this building where an al qaeda member was arrested in 2007. paul is serving a long prison sentence for plotting attacks but his wife lived right next door to zakia and joffery. we went to a nearby mosque where paul used to pray to see if anyone there knew joffery or zakia. >> i met joffery. the other two i'm not familiar with. >> he is the board president. >> there's been a number of people that have passed through these doors that ended up being

associated with extremist groups. >> there have been a few. >> how do you explain that? >> they were not actually involved in the mosque too much. if someone wants to come and worship they're become too. what they do outside is their own business. violence, terrorism, these are direct contradictions with the teaching of islam. the fact that they were living on this street concerns me or attending the mosque concerns me. >> did you miss something? >> i don't know. i don't think so. >> but clearly something was happening down the street. a family was becoming a cell. 17-year-old rasal was spending more and more time with his sister zakia and her new husband joffery. >> he brainwashed him into joining as well. >> so you think joffery was the one that made the younger brother extreme? >> definitely, yeah. >> in 2012 and 13 authorities may have had their best chance to stop this american isis cell. the fbi got a tip warning that

joffery might be mixed up with jihadist extremists. what's more, he and his wife travelled to kenya where they claim to have lost their passports. according to his skype text with phil he was interviewed by the fbi and zakia and joffery were on the watch list for terrorism. >> his mom called one day and i was like how is joffery doing? i haven't heard from him. she said he joined isis and went overseas with his wife and also took her brother. so they all went to go fight. all three of them. >> that was news to phil in columbus. >> when did you learn that he had actually gone to syria to join isis. >> i didn't know about the isis part until today, right now. >> you didn't know until right now? >> i didn't know until right now. he actually is? >> yes.

>> what a shame. >> we later learned rasal was killed. he was according to one family member in the wrong place at the wrong time. that would be syria in the age of isis. but zakia and joffery are said to be alive and well working at this well equipped hospital in the capital of the so-called islamic state. about ten months ago they had this baby girl and named her miriam. >> you know what isis does. >> yeah. >> the beheadings, the brutality. >> very extreme. >> he heard that joffery was present at a mass beheading of christians. >> do you think the boy you grew up with who became this man is capable, was capable of doing that kind of thing? >> yes. because i mean if he talked

about people that are killing muslims he'd do it in a instant. >> you don't think somebody had a duty, you or others had a duty to pick up the phone and say hey this guy is talking about killing people? killing americans? they deserve to die? no alarms went off? >> at the time no. >> if not you, why didn't anyone else in the family pick up the phone? >> i personally believe they were either scared or they just didn't care too much about him. >> in a written statement the family said joffery's actions and decisions have been heartbreaking and that we do not support his personal choices. off camera his mother told us he is in contact with her over encrypted text messages. >> as serious as the threat is here in the united states it pales in comparison to the threat faced by our closest western allies. >> john is the assistant attorney general for national security. >> we found a young man, joffery who one of his acquaintances

reported on him to the fbi. he attended amos k where a former al qaeda member who is now in jail attended. he was known to his family members to be coming increasingly radical and dangerous. yet he managed to travel abroad multiple times. >> i could talk about particular cases here but i think at the beginning of the threat we needed to get better at disrupting those that would travel oversaes as foreign terrorist fighters. we need to work with communities to do everything we can to disrupt those that would go join this terrible group overseas and that might try to return here to commit attacks or atrocites there. >> they're seeing a drop in young men trying to go overseas to join isis but the former fbi agent says the threat will remain unless we take a smarter

approach to counter the isis message. >> well i think this is the tip of the iceberg. >> tip of the iceberg implies that the isis problem in america is much bigger than we think it is. >> if it's not now it would be bigger. if we don't do something about it fast. >> i can tell you right now people are not going to like to hear that. >> well it's my expert opinion. it's the fact that i believe in. >> coming up. >> i feel like a high school kid again. >> swimmer michael phelps goes for olympics number five. tonight, the new father opens up about his own father. >> the feeling of plead guilty abandoned by my father i was a kid that always wanted a family. >> a powerful conversation with matt lauer. >> the world will see me in a different way. today's the day! oh look! creepy gloves for my feet. when i was a kid there was a handle. and a face. this is nice. does it come in a california king? getting roid rage. hemorrhoid. these are the worst, right? i'm gonna buy them. boom. i'll take them.

>> more than 3,000 miles away from the deepest continent is a sliver of land so unique their mission is nothing less than learning how to save the planet. >> we're in a place you probably never heard of. this is where fish and birds and coral abound like few other places on the planet. living proof that nature can heal itself. we like to think of it as paradise lost and found there's a thousand miles of water between hawaii and there. we loaded a plane with gear from

the nature conocservancy. the u.s. military use this as a base of world war ii and conveniently left the run way. they have a research section and most of the tile the only people here, a skeleton crew of four stephanie is a senior scientist with the nature conocer -- conservancy. there's thousands of birds nesting here. tripping over crabs. >> it's a petri dish of possibilities. especially impressive because it was flattened in world war ii to make room for 2,000 u.s. troops.

yet here birds thrive. free because a nonnative species were eradicated. >> how important is this habitat? >> there are no mamalian predators so they can breed to their heart's content. >> they're doing a great job at it. >> yeah. >> do you ever get tired of just standing here and watching this unfold? >> never. never. una fantastic spectacle. >> it is a welcomed place for all kinds of birds. red footed, masked and truly a sanctuary.

>> birds like to hang out on either side. there's only 7,000 in the whole world. i talk to them sometimes they talk back. >> what you get from a few days is a clear understanding of the balance of nature. what they leave on the leaves gets washed into the sea and where there is plenty there are some like these that came to visit us every night. this is u. s. territory and a cooperative effort of the department of the interior and u. s. fish and wildlife service and nature conservancy. it's totaling half a billion acr acres. >> huge big swaths that are

protected. what does that mean? >> it's protected so that they stay wild. we'll never have condominiums here. the critters have homes to live in without having to adapt too much to having people around them all the time. >> can you afford to have these mon you ms out in the middle of the pacific ocean where nothing and everything happens? >> the simple answer is i don't think we can afford not to. >> what does it mean for you to be here and to see howell this place is doing? >> it feeds my soul. it's a part of who i am. you're going to make me cry. yeah. very lucky. the best thing that we can have in life is to do something that we believe in, that we're passionate about. yeah. bad tears. >> good tears.

they continue to rise and needs to rebound. but as the leafs go so go the oceans. oceans that feed us. oceans that help us breathe. >> it's the imagination. >> where there's good healthy coral there's lots of fish and fishing is illegal within a 50 mile radius. >> this is what is so cool. we have it right in front of us at the same time. >> i could get used to this. coming in off the left. >> >> we don't play it.

>> the sharks pose no threat to us. reef sharks no bigger than 5 feet or so. but let's be honest, they are so cool to see. so close. >> this is your office. coming to work every day is not so bad when you're like this. >> it's one of the last best places on earth. a reminder of how things could be. how they ought to be. >> one of the unique things is that it's got a population of 4. right? so there's very few places in the world that you can access to study coral reefs where you can really minimize human impacts. so we can ask questions and better understand what's happening on a reef and we can eliminate all of the confusion of what people create basically when they're living near a coral reef. we can see it more clearly here. >> it's taking the static out of

a radio signal. >> that is a perfect analogy. >> i think what's happening is an sos signal for the planet. >> think about it. it's global and it's dramatic. it's a screening that we have to do something. >> it's a visible signal. >> it's the evidence of human carelessness is everywhere. it floats in from all over the pacific. >> here we are. the most perfect place left on the planet and there's this. >> right. >> there's crap like this all over this beach. >> how can this be? well we're doing a really good job of putting a lot of crap in the ocean and we have to stop,

you know? this is about all of us changing our behaviors and all of us getting involved. >> do you think douk that? do you think you can actually get people to sort of change their behavior enough to bring the planet back to some semblance of nature? >> so my answer to that is if i didn't what the hell am i doing, right? i would be crazy. i would be crazy to be doing this if i didn't think it was possible for us to do that. >> are you crazy? >> i don't know. i don't think so. >> after three days here, we had seen so much. but there was one more boat ride ahead. to one of the most delicate spots. allergies with nasal congestion?

>> and no doubt they live a full colorful life. >> is this paradise? >> you know, is this paradise? i'm not sure if paradise exists anymore. to be completely honest there's no place in the world that is untouched and to me paradise is a place that is completely untouched. there's garbage on the beach. we've got impacts of climate change and sea level rise happening here but this is pretty close. it's obviously beautiful. it's teaming with life. it's a place of inspiration. it's as close as you can find to paradise i think these days. >> coming up, candid, courageous. >> i just sent myself down a downward spiral. i had to get something under control. >> olympic champion michael phelps on his secret struggle. >> i never heard you say the things you're saying right now. why do so many businesses

medals. 22. than anyone else in history but for all of his conquests michael phelps was privately dealing with inner demons. >> i don't know if it was afraid of letting go and showing who i am or what it was and i finally was just like screw this. i'm not hiding behind anything anymore. i am who i am and if you don't like it it's not my issue and it's not my problem. >> most of the world first heard the name michael phelps at the 2004 athens games. >> michael phelps is the biggest name of these games. >> it's also the year i first interviewed him in his career. >> congratulations. good morning. >> those interviews continued in pedestrians jing where he won 8 gold medals. >> we're delighted to have michael phelps with us. >> to the 2012 london games. london was supposed to be his olympic swan song as he told me back then. >> i'm done. i'm finished. i'll retired. i'm done. no more. >> we're now learning at the time he could barely stand

swimming and his relationship with his coach bob bowman, someone he trained with since he was 11 was often toxic. >> prior to london was there ever a time you thought he wasn't going to go. >> yes. >> you thought he would quit? >> yes, i hoped he would. >> why. >> just because i didn't want to go through this and i thought it was going to end really badly. >> their relationship had become a lot like a dysfunctional married couple. the coach no longer wanted to deal with phelps defiant behavior like missing practices, a lot of them, just before london. a fact they kept hidden from the public. >> let's go back to the days before london. i was rather surprised to pick up a copy of sports illustrated magazine and there you are on the cover and it told a story in the magazine about how in the months leading up to london you and bob were not getting along all that well and one time in particular you had a brutal fight. >> there were a couple of them. >> he says we go at it. world war iii.

i smashed my watch against the wall. we get into the parking lot i flip him the bird and he flips me the bird. he doesn't come back for ten days. >> that sounds about right. >> this is leading up to london. you're in the prime of your training for the olympic games and you don't show up for ten days. what's going on? >> i didn't care. i honestly didn't care. >> he says he came back on day 11 because matt lauer was in town to interview him for the "today" show. >> i had something to do. >> they had no idea. that's what our preparation was like for london. >> no one did. that's why when i say i almost got away with it. >> you never -- i remember talking about your training. >> i was pretty good at putting on a face. >> you were saying it was going pretty well. >> i was pretty good at that. pretty good he now admits at not telling the complete truth. what's surprising is he won six medals in london. four gold, two silver. behind all the glory and the amazing accomplishments was a

person that didn't like himself. >> 100% i was lost. pushing a lot of people out of my life. people that i wanted and needed in my life and running a escaping from whatever it was that i was running from. >> everything seemed to come to a head on september 29th of 2014. phelps had been gambling and drinking that day at a casino in his hometown of baltimore. driving home in a white land rover he illegally changed lanes inside the tunnel. police also clocked him going 84 in a 45 miles per hour zone. >> i sent myself down a downward spiral. i think it was more of a sign than anything else that i had to get something under control. whatever it was. i look back at that night and everything happened for a reason. i drove that way if i ever would go home from there i never go that route. >> a cry for help? >> i believe so yeah.

i really do. >> phelps was arrested for dui. it was his second time for the same offense. soon after he was released from jail phelps retreated to his bedroom for four days. >> i was lowest place i've ever been and honestly i sort of at one point i felt like i didn't want to see another day. i felt like it should be over. >> after some tough love from friends and family, phelps snapped out of those dark thoughts and checked himself into the meadows, a rehab clinic in arizona. >> the first couple of nights were brutal. i probably cried myself to sleep for four or five days. >> in listening to and reading the things people close to you have said about the incident, nobody uses the words alcoholic or drinking problem. so are you an alcoholic? >> i don't know. i would say binged more than anything else. >> so a drinking problem. >> no because like -- you can

put a beer in front of me or an alcoholic drink in front of me and i won't feel the urge to drink it. >> so you checked yourself into the meadows for 45 days. you said you don't know if you're an alcoholic. maybe have a binge problem. did you check yourself into treatment because you had a drinking problem or because you had had a public relations problem? >> i checked myself in because i was at a point in my life where something needed to change and i needed to figure thicks out. >> in rehab therapy phelps said he felt with a major issue in his life. his dad. his parents divorced when he was nine. he was raised by his mom debbie. a familiar face pool side. as for his dad fred, a retired maryland state trooper, phelps said he didn't see much of him over the last 20 years. >> one of the biggest things that i was able to really overcome was the feeling of being avoided by my father. being abandoned by my father and i was a kid that always wanted a family. whether our parents are together or not, i still wanted a mom and

a dad. i never had that for so long. >> phelps said there was a break through in the relationship when his dad accepted an invitation to >> it showed that he wanted to still be in my life. so that feeling that i had of being avoided and abandoned maybe was a misunderstanding. i think we learned more about each other in that visit than we did in the previous 20 years. >> you know what's extraordinary for me, i've known if you for a long time. i've asked you about your dad probably in four or five different meetings. >> i've dodged it every time. >> every time you dodged it artfully. i've never heard you say the things you're saying right now. >> it's because i'm comfortable about it. i'm a lot more laid back, a lot more relaxed, a lot more open. >> after rehab, phelps received a suspended one-year jail sentence. he said he hasn't had a drink since october 2014. phelps is now turning his life
