those stories and more on assignment. >> good evening from the nbc newsroom in new york. for the next several weeks our correspondents travel the world to report stories we hope you'll find powerful and provocative. first up a story that's become part of the presidential campaign. it's prompted months of questions and an fbi investigation. hillary clinton's use of private e-mail for official business. the first clue came from a hacker halfway around the world. she went to romania to find him. >> you hacked your way into the bush family e-mails. you hacked your way into collin powells e-mails and uncovered that she was using a private e-mail server and many more. >> his name is marcel lazar.

and this is his first on camera network interview. >> so unemployed former taxi driver in romania with a beat up old come pewter and cell phone. >> yeah. >> is able to hack his way into half of the washington establishment. >> i'm sure a lot of, a lot of people are doing this right now. >> he's an unlikely figure at the center of the hillary clinton e-mail controversy which dogged her campaign from day one but just who is this mysterious hacker and what are his motives? that's what we have been investigating since we found him in romania. a country considered a breeding ground for cyber crime. >> welcome to hackerville. >> hackerville. this is sort of the scam capital of the internet right here. >> yeah. you could say that. >> computer security expert is from hackerville. in the foothills of the alps.

throughout this poor city the trappings of wealth are everywhere. that's because internet scammers and hackers flourished here. over the years building americans out of billions of dollars. >> this business was huge. booming. and it's called that. >> how many cyber criminals are you tracking? >> we tracked him down. and when we met him. and it's hard time for his hacking crimes here. >> gucci and lucifer.

>> the devil. >> yeah. >> he is 44 years old. has a wife, daughter, and a high school education. when he lost his job as a taxi driver he says he became so bored he began to hack. and that eventually lead to his arrest. >> i want to talk in private just for a few seconds. >> it's clear he works the angles. before we began he asked us for money. >> we can't pay for interviews. it's just against nbc rules and against network news. >> in this case i'm sorry i'm not going to take the interview. >> okay. >> a few minutes later he dropped his demand. >> okay. we'll do the interview. >> okay. as we talked he switched from romainian to english. >> how many accounts did you

hack during that time? >> i don't know. maybe 100. >> most of them famous? >> yes. >> he started out by hacking romanian officials. then american elite. they're part of an elite group called the illuminati that controls the world. >> my actions are unclear. they're to unmask the illuminati. >> it sounds crazy that there's a secret cabal running the world. >> it's not that incredible. it's very probable. >> to penetrate the bush's world he hacked the e-mail dorothy bush. the daughter of one president and the sister of another and that's how we all discovered george w. bush was an amateur painter making public a hobby that until then had been private and there was more. >> when you hacked into dorothy bush's e-mail account you found out all kinds of intensely personal things about her father. about his illness.

about them planning for his funeral. should you have made that stuff public? >> the decision to make them public was not mine. i sent them to a certain address and the people running that site decided they should be made public. >> that's copping out, isn't it? come on. >> he also went after colin powell breaking into powell's e-mail and facebook accounts. he's made racist remarks about powell as he did about others he hacked. as for his hacking ability, computer security expert says what gucifer did, did not require advanced technical skills. >> so he wasn't a hacker. >> he is not a hacker in my opinion. he was a guesser. >> a diligent guesser. >> yeah. searching on the internet find as much information as possible and put them together and try to make a list with potential passwords. >> he did pretty well. >> he did pretty well but he's not a hacker. >> whatever you call him in 2014

he scored his biggest hit. he got into the e-mail of sidney bloomenthal and noted a particular e-mail address. >> and when you saw hdr22, did you know whose e-mail it was. >> at that very moment i thought it could be hilary diane rodham clinton, yes. >> and you said to yourself. >> yes. something like that, yes. >> wow. >> he copied private e-mails from bloomenthal to clinton. some referring to the attack on the u.s. conciliate in benghazi. one he wrote, the following information comes from extremely sensitive sources and should be handled with care. he put a g on the document and passed them to the smoking gun website and the russian news site. >> were you ever working for foreign government. >> no.

>> you western working for the russians, the iranians, any foreign government? this was all done on your own. >> yes. >> a lot of people feel that you did what you did in order to get famous. be a star? >> no, that's misinformation. >> for two years his discovery that clinton used the private e-mail address went largely unnoticed but in 2015 the new york times revealed it was the only address she used for official business as secretary of state. and then came the news clinton had her own private e-mail server in her home. >> it had numerous safe guards. it was on property guarded by the secret service and there were no security breaches. >> critics charged that national security was compromised. the fbi launched an investigation. >> when hillary clinton says her server is absolutely safe your laughing. >> that's a lie.

>> that's a lie? >> yes. >> it's not safe? >> it's not safe at all. >> in our interview for the first time, gucifer claimed he got into the clinton's server. >> by running a scan i found that server was completely unsecure. >> i want to make sure that i understand what you're saying. you're saying the clinton server was unprotected. >> yes. >> and you had total access to what you wanted to download. >> yes it was like an open orchid on the internet as many such servers are. >> what did you find? >> there were hundreds of boring stuff, political stuff from texas and elsewhere. there were e-mails from hu huma abedin. >> did you download all of it. >> a part of it. a little part of it because it was boring. >> so you saw hillary clinton's e-mails themselves. >> not just the sidney bloomenthal material but you went right inside of clinton's

site and saw everything. >> that's absolutely right, yeah. that's absolutely, right. >> but did he really get into the clinton server? there's plenty of reasons to doubt him. we asked him to show us some of the documents he claimed he downloaded. he showed us nothing and unlike in many previous hacks he posted no proof online. none the less we talked to a number of the nation's top cyber crime experts that say gucifer's allegations should be taken seriously. among them, former fbi special agent. >> it is certainly credible based on what he says he has done. >> he ran one of the fbi's biggest cyber crime investigations ever. cracking the legendary case of the online black market called the silk road. >> he is now with the research group. >> based on what he told us and we have given you a chance to review what he told us is it credible that you could have in fact hacked the server? >> it's plausible because he did get access to e-mails that

allege dhi came from that server. each e-mail has the header and that tells you the information and the path of where it came from. >> based on what we know about the credibility of past hacks what do you make of this? >> he had the potential to do very dangerous things with a computer that he wasn't allowed to be on. entering a computer you're not allowed to enter is hacking. >> and a crime. >> felony in the united states, yes. >> so whether he knows it or not he has just admitted to committing a felony. >> he's admitting that he committed a felony. >> and if he's lying -- >> that seems silly to me. to go on television and admit to a felony you didn't commit seems silly. >> as for secretary clinton this week she continued to maintain her server was secure in an interview on msnbc with andrea mitchell. >> have you been contacted or your representives contacted by the fbi to set up an interview. >> no. >> any indication that your private server was hacked by foreign hackers? >> no not at all.

>> we asked the clinton campaign for a comment about gucifer's application regarding the server they blasted his credibility. >> there's absolutely no basis to believe the claims made by this criminal from his prison cell. we received no indication from any government agency to support these claims. >> in fact the fbi review of the clinton server log showed no signs of hacking according to a source familiar with the case. but chris says server logs are not necessarily comprehensive. >> so it is absolutely clear that if the server were breached there would be a log of it somewhere. >> no. >> so it may be that there's no breach that was recorded but that doesn't mean this was no breach. >> correct. >> but a caution. he also says the very nature of gucifer's handiwork as a criminal hacker makes his word suspect. >> so someone that does what he does is a sort of congenital liar. >> pathological well practiced

liar. >> as for the fbi no one is saying anything on the record. >> i just interviewed gucifer this morning. >> i can't comment on gucifer. >> he is being extradited in the u.s. in the weeks and months to come. >> i can't comment. sorry. >> shortly after our visit marcel was, indeed, extradited to the u.s. he is now in jail in virginia awaiting trial for hacking sidney bloomenthal, colin powell and others. he pleaded not guilty. one thing is clear. we're not the only ones interested in talking to gucifer. sources close to the investigation confirm fbi even escorted him from romania to the united states. and question him about the clinton's server now that he is in u.s. custody. many officials emphasize to us investigators have seen nothing so far that substantiates his claim but the investigation

continues. >> was it your intention to try to effect the presidential campaign. >> no, at that time i wasn't thinking about the campaign in 2016. but that's where things are heading. >> coming up. >> of course you want to give him a chance. >> his devastating brain injury left his family with a difficult choice. >> they said it's probably time to let him go. >> then he made an astounding recovery. can others too. >> do you worry that you give people false hope? >> i worry more about taking all the hope away. >> life and death information that could effect your family. ♪ ♪ you live life your way. we can help you retire your way, too.

functioning independently. in most cases they're not living the life they did before. >> they're okay with their family so it does raise the question of can we make the right decision in the first 10, 14 days of the recovery trajectory. >> it's within the first crucial days after a severe traumatic brain injury that families are sometimes given a choice. if doctors believe the prognosis looks poor. do they want to keep their loved one on life support or let him or her die peacefully? but he believes that may be much too soon. he juans the medical community to pause and give patients more time to see if their brains can heal before making those hard decisions. patients like patrick mahoney. patrick was 26 studying poetry at the university of new hampshire which was a perfect fit for him says his sister.

>> he was always a good student growing up but he always had an interest in writing. >> patrick was equally passionate about his girlfriend ann. >> he introduced me to lots of new music. hots of new literature. it was like a very fast like, fell very fast for him. >> and then came october 27th, 2010. patrick had been heading home late at night. the car hit him from behind. >> picture your body flying in the air 90 feet and landing completely on your head. >> a week later doctors met the family and told them they'd have to make a terrible decision. >> they said it's not in your favor to keep him going because looking at the facts that we have, it's probably time to let him go and it's going to get harder the longer you wait. >> how soon was this decision necessary? >> they said over the weekend. >> i remember we would go around the table and what do you think? what do you think? and everyone was very honest.

i don't think he would want to live this way or i don't think i can let him go. >> patrick's sister, the grim prognosis still echoing in her head had already travelled home to begin funeral arrangements when their mother called. >> she said we're going to give him a shot. we're going to keep him going. >> how did that feel? >> are they in denial? i'm a mom myself. two kids. to watch your kid suffering there. of course you want to give them a chance, okay? but were they thinking about the future? i was very afraid. i was afraid for them because they were going against the medical advice. >> in the days that followed the family noticed what they hoped were small signs of improvement. a squeeze of his hand. a small wink. those first movements can be subtle but crucial because they can signal that a patient is getting better. and this is important, they may take weeks to appear. >> we're talking about simple

things like purposeful movements. something has fallen over my eye and i reach up and push it away. that's a very complex response. often that behavior does not emerge until three or even four weeks after the injury. >> espn? thumbs up? espn. >> still patrick was unable to communicate until someone got an idea. >> you know, he's a writer. give him a pen. give him a pen and paper and he writes dear ann with a heart. >> i was ecstatic and i was weeping. i was so relieved. >> but recovery that would take months and months of intensive therapy and every human act he had to learn all over again. which he did. . patrick is now a mental health

counselor. he still deals with the effects of his injury. he has posttraumatic epilepsy and recently finished speech therapy. >> i wanted to maintain a sense of optimism and positivity. >> what do you think when you're presented with that stark fact that a couple of days or a week or so after your accident your family were faced with this monumental decision? do we try to keep him alive or do we say good-bye and they could have done either one and with equal love for you. >> that's very difficult to hear, you know, in my own head i was just in there thinking like i'm going to get better so i hope you guys, you know, meet me over there. >> so this is patrick's scan from about five days after his initial injury. >> the doctor consulted on patrick's case after that initial decision. >> in his case, the family was told they'd have to make a very serious decision here and -- >> yeah. >> it's reasonable when you look at the picture there.

>> not unreasonable at all. this was a very big injury. >> what is it like for you to see the way he is now? >> it's invigorating. it's invigorating and also humbling because i can't stand there and tell you that this individual was going to go on to make that recovery. >> which is exactly why he wants the medical community to wait to see if there are more patricks out there. just how many could recover? >> maybe as many as one in five and that's big news. >> do you worry that you give people false hope with this sort of talk? >> i worry more about taking all the hope away than i do about giving false hope. i think hopelessness is much more difficult to deal with. >> to be clear we're talking about people that suffered an accident and not someone whose brain was deprived of oxygen, say from a heart attack. >> i think at this point, the research is still early and i think we still need to be realistic. >> dr. robert true works in the icu at boston children's

hospital. he's also the director of the center for bio ethics at harvard medical school. he calls the work exciting but not definitive enough to overhaul the whole system. >> waiting has many consequences for the patient, the family and society. >> negative consequences. >> potentially. >> why? >> let's start with the family. those are the ones that are often the most impacted. >> have you seen patients in situations where a decision to hang on was made and later regretted? >> for sure i've seen families where i have felt broken hearted that they had gone down a pathway that you can see is not going to end well. and you can see the toll it takes on marriages and family finances and it's a huge commitment for a family. >> and he cautions about overwhelming an already taxed health care system. >> we don't have the rehabilitative resources, the hospital beds to care for all of the patients that would now come

into that system. >> do you believe they can afford to wait and wait and see if they're one of the one and five that make it. >> we have a big disconnect between the way the brain recovers and the way we deliver health services. they don't match. >> recovery takes time. will emory's care consumed his mother for the past six years ever since he was injured in a car accident at 19. tracy never considered letting him go. >> the icu nurse came to me and said you have to think about would will want to live like this. i took it that i should start considering if i was going to have to remove life support and i told her to just step away. it wasn't an option. that we were going to go for it. >> will was mostly unresponsive for almost a year. he finally came around.

and began a long and grueling recovery. >> what do you think? >> that is pretty good. will is great. is he 100%? no he is still in therapy and he makes gains every single day. >> will's days include round the clock nursing care. daily medication, numerous therapies, all hugely expensive and all performed under tracy's constant vigilance. >> i have no regrets. >> i don't have any. >> i have done the best i could and i have done it by myself and i still have my son. and he is in pretty good shape. >> and just look at how patrick is doing. he and ann are married now. expecting a baby in june. the former poetry student has also just published his own book of poems using the acronymn for

conrad's heart of darkness. they brought skulls home to belgium where experts thought they discovered a new third species of gorilla. >> so this could have been a missing link connecting and that sounded fascinating. >> the fast nation with the mystery apes was rekindled after a swiss photographer arrived in 1996. >> he was bringing out pictures and reports of ground nests. that's gorilla behavior. there was a speculation that maybe it was a hybrid. a new species of great ape or something else. >> scientists intrigued by what they heard began coming to billing. they installed motion detecting cameras deep in the forest and finally they were able to capture clear images of the apes which looked like large chimps but behaved a little like gorillas. dna samples proved that they were chimpanzees after all.

it's just that the chimps of billy forest behave a little differently. >> they have different diet. different culture. in fact, here's a great example right here. this is a mound. >> termite nest. >> exactly. they build these structures all over the forest here. with one exception they're the only population to eat this. >> but it's not just their cultural uniqueness that makes these animals important to hicks. he claims they are probably part of the largest population of wild chimps left on the planet. his discovery got a lot of attention around the world. today these chimpanzees and the other animals of this wilderness are in danger. so about a year ago park rangers started patrolling the forest for the first time ever. while hicks was looking for chimps, the park rangers were hunting for hunters. and there were signs of poaching

everywhere. they found and disabled dozens of snares, traps made of wire or vines designed to catch wildlife. >> so if an animal steps in it you grab the leg. >> chimps often lose fingers and sometimes hands to snares like these. given what we were seeing it's hard to believe that this is a conservation area where hunting and fishing are against the law. but there's a reason poachers hunt with impunity. the billy forest is effectively lawless. this operation represents the first conservation effort in this part of the forest. the rangers are here because of this man from the african wildlife foundation which helps train, equip, and pay them. their effort paid off immediately. the rangers discovered a poacher's camp up ahead. >> do you think it's going to be

hostile? >> hopefully not but one never knows. >> a couple of scouts determined that the camp had been abandoned. it appears the poachers took off in a hurry. >> there's nobody. >> nobody. >> but it looks like there was people here recently. >> you can see they were cooking here and the fire was here. >> evidence of illegal hunting is all around. including shotgun shells and racks for smoking poached meat. >> and then i found over here by the fire pit over here some monkey bones. >> so they were hunting monkeys as well. >> clearly, yes. >> the rangers also found this item that their commander explained is part of a deadly weapon. >> so they were making a cross bow out of this. >> a cross bow. >> these arrows, they're black on the tip. does that mean they're poisonous. >> don't touch. >> are you going to destroy this camp now? >> this cannot be here. this has to disappear. >> so this has to be destroyed to stop the poaching?

>> armed poachers are one thing but at any moment these rangers could be facing even more dangerous enemies. billy forest is located in a corner of the democratic republic of the congo that's seen decades of war which is often spilled over to the failed states of central africa. one of the most notorious remember nance is the lord's resistance army better known as the lra. the group and it's leader, the war criminal joseph coney are now on the run. some of the fighters are now hiding out in the forest where they live as outlaws. >> they can kidnap civilians which is a classic mo. >> which is why the wildlife foundation hired him to train the rangers to fight. the former israeli comando is teaching them everything if how to safely detain poachers so surviving a fire fight. and setting an ambush.

>> these guys will shoot. >> they have to train for a fight to the death. >> this is not just is park rangers. >> counter terrorism forces. >> security i would say. >> it's made up and special forces can be and so far they have trained rangers. >> it's not enough at all. >> the next day the rangers discovered another camp where they detained two young men. we saw how surprised these poachers were. to see the law being enforced for the first time. >> what are you doing here in the forest? >> he says he's fishing.

>> but they were fishing by poisoning the river. and the rangers found a large caliber one. >> he is taking the weapon. can't leave them here. >> he said he would have to get away from hunting trails. so he and his team hike for another 14 days and covered more than 100 miles. they reached a part of the forest few humans have ever visited. and there at last they caught a few glimpses of the bili forest chimps like this young female who clearly didn't like the attention. hicks thinks she has never seen a human before and for now among her own kind, she is safe from peel. but when we went outside the forest into the nearby town of bili we would discover there was a thriving market for the local

animals. and we would come across another bili ape. this one in need of rescue. that's next. if you're going to make a statement... make sure it's an intelligent one. ♪ the all-new audi a4, with available virtual cockpit. ♪ atand that in a new house,tee a fyou probably don't sharece, the same tastes as the previous owner. ♪ [ dolphin chatters ] so when you need a little house painting or a complete remodel, we'll help you get the job done right, guaranteed. get started today at angie's list, because your home is where our heart is. customer service!d. mam. this isn't a computer... wait. you're real? with discover card, you can talk to a real person in the u.s., like me, anytime. wow.

we have one more thing we wanted to show you from our trip to the congo. we have been in the depths of the bili forest with cleave hicks, who has been deeper into the forest than any other human. but when we visited the town of bili, we realized that protecting the chimps will require more than hunting down poachers. it's going to mean changing how people here live. the forest has always been a source of food. >> i think there's another monkey over there. >> monkey meat is sold openly in

the market. >> eating primates like this puts all humanity in danger. >> chimp meat is illegal, so it's traded in less public places. we saw another grave threat to bili's chimps when we followed the chief ranger as he pursued a tip. he had been told that an army officer had a baby chimp and a baboon tied to a post. the information turned out to be correct. the officer was keeping the animals as pets. baby chimps often end up in the pet trade, that's illegal because they are endangered. the officer also planned to make a gift of the chimp. the chimp whose name is cobra was saved, but now the rangers had to figure out what to do

with it. cobra was incredibly comfortable around us humans, baby chimps often are. but he is probably the sole survivor of the massacre of her entire family. and he will never be able to go back into the forest. hicks volunteered to find a new home for the little orphan. >> he has an amazing soul searching look. >> they are very, very adorable. but the question is, why is it difficult to reintroduce this chimp and other chimps in the wild? >> it would probably be killed by the chimps in the group. chimps are very zenophobic. they would kill him. >> so we need to take him to a sanctuary. >> long-term prison care. >> unfortunately, that's the best we can offer. >> hicks gently traded cobra off to his new life in a sanctuary. >> you're going to go see some more chimpanzees. >> cobra could live 20 years in
