summer that is all of our time. thanks for being with us. i'm tone' harris in new york. randall pinkston is up thank you. a two year ument just wrapped up in washington, the president saying the gathering fulfilled the goal of keeping nuclear waste out of the hands of "madmen", but more needs to be done. >> reporter: the president said that he thought the nations gathered here achieved something quite remarkable. he noted that in 50 facilities in 30 countries highly enriched uranium or plutonium have been secured or moved out of the country. that's enough material to make 150 nuclear bombs and he said as criminal gangs or terrorists or arms merchants look around for

material to make nuclear devices, they will see large portion $of the world are off limits limits. >> reporter: in the same hall where this was opened six years ago, he sounded an ominous warning of the growing threat of nuclear terrorism >> the amount the size of an apple can kill thousands of innocent people. it would be a catastrophe where global ramifications for decades. it would change our world. >> reporter: the leaders and delegates from more than 50 nations all committed to various ways to secure nuclear bomb-making materials such as highly enriched uranium and other materials which can be used to make a dirty bomb. >> there's no doubt that if these madmen got their hands on nuclear bomb or material, they would use it to kill as many

innocent people as possible. >> >> we have to stop securing these materials like they're library books and securing them like they're the gold of fort knocks. >> reporter: a man that advocates for smaller nuclear stock piles. he gives obama credit for making headway, securing loose nuclear material but says with the rise of i.s.i.l., progress is far too slow. >> this summit will make it safer. this was a good-- this is a good thing. when you're fleeing a forest fire, it's not just the direction that matters, it's the speed. can you go fast enough to get to safety before catastrophe engulfs you >> reporter: the absence at the fourth and final nuclear summit was putin's absence. he boycotted the meeting despite the fact that it sits on the largest stockpiled of unsecured nuclear materials >> they're not working together any more. years of cooperation have ended. we funded for years programs in

the states of the former soviet union to secure their materials. president putin has ended that cooperation. he has closed down facilities to any kind of u.s. cooperation. >> reporter: in his closing news conference, president obama conceded much more needs to be done. >> there is still a great deal of nuclear and radio active material around the world that needs to be secured. global stocks of plutonium are growing. nuclear arsenals are expanding in some countries with more small tactical nuclear weapons which could be at greater risk of theft. >> reporter: even though the president obama said that this is the last of these nuclear summits that will be held at the leader level, the sort of presidential level, they have laid the foundation for future work, including an international working group of experts from 30 countries who will work to continue the unfinished business of trying to secure loose

nuclear materials thank you. now to the presidential race. with just four days to go until the wisconsin primary, the rhetoric is heating up between democrats hillary clinton and bernie sanders, with clinton accusing sanders' campaign of lying. david shuster reports. >> if we win here in new york, we are going to make it to the white house. >> reporter: state and national polls continue to move towards bernie sanders. the frustration for hillary clinton is now boiling over. >> they spend so much time telling you what they're against >> reporter: pressed by an environmentalist about donations from the fossil fuel industry, clinton erupted. >> reporter: [indistinct] >> i am so sick of the sanders

campaign lying about this >> reporter: accused of lying, the sanders campaign responded by saying it is clinton who is lying. while she has not received money directly from the oil industry, she has received donations from oil industry employees. regardless, tensions between the democrats have been intensifying for days. this week after days after donald trump had abortion comments. one noted sanders longstanding support for women's right and equality and added this >> shachl on you hillary. -- shame on you. sorry, hold on. let me watch my tone. >> reporter: the contempt and ridicule of the clinton campaign was a hit. polls indicated that most young women are supporting him.

while clinton is trying aggressively to undercut his standing with younger voters, sanders is trying to undercut her support among latinos. musician another sanders supporter noted clinton's praise of former secretary of state henry kissinger whose policies supported genocide across latin america >> it will represent to consider yourself latin american and vote for her. >> reporter: while the democratic race gets harsher, republicans, at least for now, are talking about g.o.p. harmony. just days after saying he might not support whoever wins the nomination if it's not him, donald trump on thursday went to a previously unscheduled meeting with leaders of the republican national committee. then on fox news he was evasive. >> we met with the staff and they're very good people,

actually terrific meeting i think. it's really a unity meeting >> reporter: ted cruz who was hoping for a contested convention, put that talk aside on friday. instead he released a video clip from months ago. >> i would like to invite donald right now to engage in a one-on-one debate with me any time. >> reporter: cruz then tweeted: >> reporter: cruz posted a link to this debate >> we have had 11 debates. we will go on forever with these debates. >> reporter: with the 80s pop song never going to give you up, it plays out with a reminder that this is april fool's day. foolish or not, cruz has repeatedly brought his love for pop culture in the campaign. last fall he acted out his favorite scene from the movies princess bride >> liar. liar

>> he came that and suddenly his wife goes liar, liar. shut up witch. i'm not your witch or your wife. but after what you said i wish i wasn't >> reporter: a year ago, cruz did a mock audition for the simpsons. >> smithers, release the houndzs. excellent. >> reporter: laughs in the republican race, the presidential nomination grinds on new york news the department of motor vehicles website to register voters on line. this year it saw a last minute surge with 41,000 application between march '10 and 20, but half of them first time voters all determined to make a difference in the primary. >> reporter: 35-year-old will be voting for the first time april 19 in new york's primary. why have you nvr voted before

now some-- never voted before now? >> i'm not independent. >> reporter:-- >> i was not interested before >> reporter: why are you independent now? >> because there comes a time when you want to have a voice >> reporter: we met him at a rally where there were many registered voters, young people. when did you register to vote? >> my birthday >> reporter: he plans to vote for hillary clinton r there any republicans in your house? >> yes. gentleman who? >> me >> reporter: why are you at a hillary clinton rally? >> because he asked me to come >> to keep his mind open >> reporter: a few rows back. >> reporter: a lot are supporting bernie sanders >> a lot of my friends are >> reporter: have they tried to change your mind? >> yes. they this then they give me baseless attacks. i've researched and i know they're not true and i know why i support her >> thank you all so much >> reporter: among them, this

woman may be in the minority. a few hours north of bihar-- harlem, a voter registration campaign. is it difficult to get students to register? >> people are really excited to participate. a lot of these kids have watched politics from the sidelines >> reporter: this man has democratic politics in his d.n.a. his grandfather was a top aid to president johnson and cabinet secretary in the carter administration. the younger was supporting the anti establishmented candidate, bernie sanders. >> enough is enough. >> he has brought to the table and shown people that there's a chance to change the system and bring about some progressive value to a lot of students here. >> reporter: these students are all 18 and newly registered to vote. >> reporter: had you always planned to register as soon as you could or did something motivate you to register this year? >> i had always planned on

registering independent, but in seeing bernie sanders in this race, he represented so much idealism that i didn't know existed >> reporter: were you surprised that so many of your fellow students were interested in registeri registering? >> i don't think i was surprised. you see apathy and i think that's changing. i think it's an important thing to do. i was xid to register to vote >> reporter: all three students support bernie sanders. >> i registered to vote because i want bernie sanders to be elected, but i also care about voting in localities of other smaller elections for people in the house in the senate which i feel that sometimes democrats don't show up to enough >> reporter: this year new york voters in both parties have a connection to three of the candidates. a former senator, a famous real estate developer and a brooklyn native. >> this contest is so dramatic.

it is not just a contest on the republican site and one on the democratic side. it's on both sides. >> reporter: analyst says the anti establishment candidates this year, trump around sanders, are most likely to benefit from the rise in voter registration. >> any time they're able, if we look at the past primary and caucuses, they're able to bring new voters in, it is the outsiders of the anti establishment folks who seem to benefit from that surge in registration. >> reporter: whatever the final number of registered voters, the more important number will be turn out, how many people show up at the polls april 19 a senior reporter for the center for public integrity. he is joining us from washington dc. you just heard that we have hash words not from republicans but from the democrats. hillary clinton caught on tape accusing bernie sanders after lying, about her acceptance of

money from energy companies. how do you think that's going to impact her support? >> it could have an affect, certainly. bernie sanders is struggling everywhere which we possibly can to close what is a major gap between him and hillary clinton. he has two problems here. number one, he has got a gap in pledgers. he is running into the wall that is the super delegates, free agents on the democratic side who can basically go to the convention and vote for whomever they want to. most of them are cutting hillary clinton's way. he is being aggressive. he has got a lot of momentum in the sense that he has won several of the last contests and he faces a challenge coming up in new york which will be the biggest one that he will face we see young people seeming to be burning for bernie. a lot of them are in any event. does hillary clinton face the

danger of alienating his supporters and assuming she wins the nomination, won't she need them for victim in november? >> it is something that she has to consider. she is trying to turn to the best of her ability to the general election. she wants to get beyond bernie sanders. she wants to go and fight against donald trump or whoever else the republican nominee is going to be, but bernie sanders many not go away. reports are out that he raised more than 40 million dollars just in this past month in march, so for somebody who is a candidate not in the lead in his or her party, that's remarkable at that stage of the game. he still has an incredible amount of energy. the rally that he had last night in new york is evidence of that. as a result, this is going to be very difficult for hillary clinton to not only just have a glide path to the nomination, which is far from certain at this point, although she definitely is in the driver's seat, but also too, as you suggest, pivoting to the general election if she does eventually become the nominee and fake a lot of those bernie sanders

supporters with her. some may be feeling burned themselves that hillary clinton is a nominee and checkout altogether is a victory in new york good enough for the former secretary of state or does she need to smother bernie sanders in order to keep her momentum going? >> we talk about momentum a lot. we're all at fault for that, but really this is a game of math at this point. if she can continue on the path of staying ahead of senator sanders in terms of delegate count and ultimately by june, perhaps, in may, getting over the threshold that she needs to become the nominee, walking into the convention in july, then that's going to suffice, but the question of hossam bahgating, she wins the battle, can she win the war, and part of that is, indeed, going to go back to what we talked about, trying to convince those folks who supported senator sanders, who

have engaged in politics sometimes for the first time, because of bernie sanders, she too is somebody worthy of their support talking about the republicans. the latest forecast showing donald trump moving in a negative direction while ted cruz continues to move upward in the preelection polling. what would a loss in wisconsin for donald trump be the beginning of the end for him? >> far from the beginning of the episode, but it would spell a lot of trouble. under almost scenario can ted cruz catch donald trump and secure the nomination himself for the republican party prior to the convention in july. he is not going to be able to secure enough nominees prior to the convention to secure the nomination going into the convention. that is the scenario that ted cruz is hoping and dream for.

that is one that john kasich is hoping for too because if donald trump doesn't go into the convention having enough delegates, we could have a frae for all that could ultimately be anyone's race because all the delegates who are pledged on that first ballot on the republican side can, most of them kind of scatter to the wind and do whatever they want to do on second and subsequent ballots. if he does lose, then that will have ramifications thank you. >> my pleasure after working for eight months without a contract, chicago teachers staged a one-day walk out today. now school officials are trying to make sure they don't do that again. thour correspondent joins us.

>> reporter: this was one of the largest demonstrations we've seen in chicago in years. thousands of people were amarching in the streets. they shut down rush hour traffic. they were joining the teachers in their protests against the city of chicago after this impasse that they're having with the city with their contract, but the teachers were also protesting the state of illinois in the budget impasse between the democratic controlled legislature and the republican governor, browse rounder. they say impasse is cutting off funds to the chicago public schools and that is cutting the teachers money as well. >> we have had other sacrifices throughout the year, so much that we have to buy our own paper, the majority of our supplies, which if i went into the business world, that wouldn't happen anywhere else. >> reporter: about 27,000

chicago public school teachers were off the job today. that affected by 350,000 school kids here in the city of chicago. the ceo says the teachers will not be paid today. they will be docked a day's pay. they will not be fired from their job. however, he said the city is going to be pursuing legal action against the chicago teachers union. >> a permanent pre-emptive injunction against similar illegal strikes going forward into the future. we think it's important that it be clearly established that whether children are in school and being educated is not subject to the whims of the chicago students union leadership. >> reporter: the chicago teachers union in the city of chicago have had a very contentious relationship for the past few years. it started back in 2013 when the

city shut down 50 chicago public schools because of budget issues we know the governor wanted to take over the city school system, but there has been a ruling from the state attorney-general that may impact his plan. what's going on there? >> reporter: yes. that's right. what the governor was trying to say was that in order to shut down or take over the chicago city schools, he was trying to prevent the chicago public schools from borrowing money and the attorney-general said today that he did not have the authority to do that. however, governor did kon testimony the teachers for walking off the job today. in a statement he said: the ceo of chicago public school has asked the teachers to join him in springfield to

protest this impasse between the legislature and governor rowner thank you for that. up next, the desperate search for survivors in the deadly overpass collapse in india. narrowing the digital divide. how many americans are being helped to get online.

in india five officials of a construction company have been detained for questioning after the deadly overpass collapse. >> reporter: this street once under the shadow of a fly over being cleared now. >> the main part of the operation is over. the people were under the debris yesterday. the second part of the operation which you see, the fly over is still leaning in one direction.

that will be done in a very systematic manner. >> reporter: workers say it will take up to three days to remove a precarious slab that is hanging off the bridge held together by pieces of concrete and twisted iron rods. residents look on with a bird's-eye view. their buildings once nearly touched the edge of the fly over. the 2 kilometer bridge had taken up all the space which is why people and vehicles had no choice to pass under the building works. that's how two members of this family lost their lives. concrete slabs fell onto an auto rickshaw that were taking this man's son and daughter-in-law. >> translation: i my entire family is gone. i'm already 75 years old and i'm left with my grandson. what do i do about his future? i don't know what to do without

my son. >> reporter: the search for vehicles trapped under the debris continue through the night. the police say no-one was pulled out alive. the chief minister cancelled all her campaigning for upcoming state elections to survey the scene. vowing no those responsible will be punished and there will be an investigation. but in the light of day, locals say they're sceptical. they worry that the elections are the focus of politicians' attention right now. two years allowing a similar fly over collapsed in the city and although there were no casualties, people say if the government has taken action as was promised about back then and created policies and checks and balances for construction, a tragedy of this may not have happened. >> reporter: even here memories are short. despite warnings that this area is unsafe, crowds gather to watch the machinery break apart the fly over's crumbling edge. further along it's business as

usual. once again stalls set up, pedestrians passing through and vehicles parked under the bridge brussels airport is expected to reopen at a reduce level of security on sunday morning. it has been closed since suicide bombers struck ten days ago. a planned reopening today was there wartd by a strike threat over more security. the government has agreed to hire 200 additional airport police officers. a new case of ebola was declared in libeia. a 30 year old woman died at the hospital on thursday. the world health organisation tweeted a caution today although it is no longer a global health emergency flare-ups in the region are expected. the kurdistan workers party, or p.k.k., is claiming responsibility for yesterday's deadly car bomb in southern

turkey. seven police officers were killed. at least 27 others injured. >> reporter: the explosion shattered the calm of this residential neighborhood. a car packed with explosives detonated here. the damage is clear. this family, they survived the attack. >> translation: my parents were cooking in the kitchen. i was in the bathroom. my children were studying in the living room. all of a sudden we felt the storm and felt something strong coming on to us. it was like an apocolypse >> reporter: many onlookingers stood in disbelief. many more scared >> translation: we heard the explosion. we thought it was an earthquake. we were worried and scared. >> reporter: the car was parked here and it detonated by a remote control. the bus arrived at this corner. the explosion was so powerful it shat reasonable doubt the windows of the surrounding

buildings. >> reporter: security officials say they have identified the man in this cctv footage as the main suspect. turkey is increasingly being targeted. last month a suicide attack carried out by an i.s.i.l. suicide bomber killed several tourists in istanbul. both ankara and istanbul have seen a spike in attacks since last year. the govern says the security and economy are the targets. several consulates have closed their missions and many western states have warned its citizens against visiting the country, especially south-eastern turkey. the thursday car bomb attack will only increase fears of more attacks up next, refugees in the u.s. and how some of them are working and thriving in dairy country. plus a man who risked his life

to solve racially motivated crimes. about it. >> what took place here 60 years ago...the murder of emmett till is to this day an unsolved crime. >> i wanted people to hear the true story of till. >> never thought that he would be killed for that. >> that was the first step in the modern civil rights movement. >> ferguson has a...asking for assistance with crowd control... >> we're live in ferguson, missouri. >> these young people deserve justice. >> this is a target you can't get rid of. >> they were so angry, because it could've been them. >> there's clearly an issue and we have to focus on how we bridge that. >> they say they did it because they were trying to protect my children. they didn't protect my children,

they traumatized them. >> we're just the average person, trying to go to work, provide for our families, and do what we can in this world. >> don't get lost in a sea of despair. >> i'm interested in getting us to a place where we're feeling something that looks more like freedom and justice. >> check which ethnicity - i check multiple boxes. >> this is who i am. >> were you here 50 years ago? >> yes to support the cause for voter's rights. >> we've come a long way. we've got a long ways to go. >> al jazeera america - proud to tell your stories.

>> we're here to fully get into the nuances of everything that's going on, not just in this country, but around the world. getting the news from the people who are affected. >> people need to demand reform... >> ali velshi on target. on monday, california's governor will sign the $15 minimum wage into law. california became the first

state to agree the increase. new york followed, boosting to $15 an hour but only in new york city. $12.50 in other areas. a strong unemployment report says u.s. added more than 200,000 jobs in march. the jobless rate went up slightly however. that is actually good news. >> reporter: a solid reading on the u.s. labor market. employers kept up the pace of hiring adding 215,000 new jobs, this despite a weakening global economy. the unemployment rate ticked up to 5% but for the right reasons because the number of people participating in the workforce either by having a job or actively looking for one increased by nearly 4000,000. that-- 400,000. that marks the sixth months it has increased. warmer weather helped create 37,000 new construction jobs but

manufacturing took a hit losing 29,000 jobs thanks in large part to a strong u.s. dollar making u.s. goods less competitive overseas. meanwhile, average hourly wages are heading in the right direction. after losing ground in february, wages increased 7 cents in march to 25.43 an hour. that's a 2.3% increase year over year. so, perhaps, not a raise to write home about, but a raise nonetheless there was a fear that the influx of refugees would add to u.s. unemployment, but some are finding work and thriving in new york's dairy industry. >> reporter: work on the dairy farm in rural new york is loud and smelly. this man is thrilled to have this job. he was once a farmer but later as a refugee in nepal he couldn't work for 20 years.

>> translation: with new technology here, the new system of milk in the dairy farm was challenging in the beginning, but now everything is easy. his boss is a sixth generation dairy farmer. with reliable legal workers hard to find, she jumped at the chance to hire him through the refugee milker training program. >> they bring a stable worker. it is a job that they enjoy. it's a long-term employee. we look for people that want to stay. >> reporter: this man serves as a liaison between the employers an refugees. he was once one of the 100,000 forced out of his home in the 1990s. many come to communities like this and feel at home on the farm. u.s. resettled 80,000 people since 2008. in 2012 more refugees came from buton than any other country. in the refugee camp his family

lived in a hut. now they have a five-bedroom house partially sub-sydney tiesd by a state grant. >> it is a good fit because the american workers are not interested in working on the farms >> reporter: she runs a group that is helping the people learn computer skills and english of the some of the women have also gotten jobs in a local sewing factory. >> they don't mind the hard work. it fills a need. the gaps in the workforce that we're seeing. gentleman for ray and his family, coming to the u.s. was a turning point. >> i believe that, yes, if we have a will and america is a country that i believe offers all the opportunity to grow and have our dreams come true >> reporter: while they didn't feel comfortable in a city, here in rural america they feel welcome and right at home a national effort to narrow

the digital divide is taking shape in kansas city. 100 apartments in the subsidized complex now have super fast free internet connections. al jazeera's correspondent reports. >> reporter: up until last month, this woman an her family had no computer or inhome access. >> i had no idea that it was that much more internet out there than there was. i mean, my phone was one thing and being on a computer was a lot different. it's a lot faster too. >> reporter: today she is on line. >> it logged me automatically in >> reporter: as part of a federal program called connect home, a nationwide initiative to get some 275,000 families living in assisted housing. >> it used to be a time when it was a convenience. it is no longer a convenience to

check your email and stay in touch with family an friends. it's a necessity. >> reporter: these are some of the 1300 families learning the basics. digital literacy classes like this stress the importance of not only getting on line but learning how to use the internet for education, job searching and health care. >> the next app that i want to get us into is the google docs. >> reporter: they partner with google fibre here. >> one of the things i love most about connect home is the power of residents talking to other residents when they've had this tool in their homes or getting to use the internet or find jobs or help with their kids' homework. that word getting out of one resident to another is so powerful. >> reporter: it's important because adults from households earning less than $30,000 a year are roughly eight times more likely than most affluent adults to not use the internet, even if

they have access. missouri is one of 19 states mostly in the south that have low computer ownership and low high-speed internet use. families here are getting refur beneficiaried computers >> we have a lot of material coming through here that needs to be redeployed. it can do more public good than being dismantled and sent off for reclaiming >> reporter: since getting a computer and home internet access, she has used it to find a job and as a result has even been able to buy care. is this life changing? >> yes. it is. eye get to see my chart, my medical rorndz an stuff like that with my emails. i get to give out my email address more often so i can get emails, i get to shop online now >> reporter: officials say over the next few years the connect home initial tich is expected to impact some 20,000 children in mi;; i;; ipi, i traveld

for this story >> if somebody kills me, they do. i think in faith terms. so if someone kills me, then it just means i'm going home sooner. >> reporter: investigative reporter jerry mitchell has risked his life travelling the back roads of the deep south looking for a special breed of killer. >> where the civil rights workers killed? >> right here in the ditch >> reporter: men who murdered civil rights activists decades ago with impunity. >> hauled them out of the car and said are you that n word lover? >> he said, sir, i understand how you feel and that's when he pressed his gun up against his

chest >> reporter: these were helping african americans to vote when they were ambushed and killed in 1964. they weren't alone. the back roads here still hold many dark secrets. during the violent days of the civil rights movement, african american families were hesitant to report disappearance to law enforcement authorities because they didn't trust them. jerry mitchell says they had good reason. in fact, the tree owe was delivered to a lynch mob by the county's deputy cher if, ce-- sheriff. it would take had 1 yeahs for a murder-- 21 years for a murder in the case. the master mained was this man. were you nervous? >> no. we're in a public place. it was going to be 9 o'clock at night and he was coming.

>> reporter: his investigation helped secure new evidence leading to his conviction on three counts of manslaughter. mitchell grew up mostly on unaware of civil rights movement. >> i grew up in my insular kind of white south in east texas. i didn't get exposed to a lot of it. >> reporter: the movie mississipi burning opened his eyes. as did learning about his own newspaper's past. >> when you learn the legacy of this paper, what did you think? how did you feel? >> i was horrified >> reporter: decades earlier and under different earnship, it supported segregation and had close ties to the sovereignty commission, a state agency that kept tabs on activists like the three murdered men. >> reporter: so the newspapers were an organ. >> absolutely. >> reporter: of the state spy agency. >> absolutely >> reporter: they were opposed to civil rights >> absolutely. i said when i found that out,

we've got to write about ourselves >> reporter: former governor says the commission was formed in 1956 to promote the area >> it was to be a pr operation. >> reporter: but by the 60s it operated in the shadows. >> exactly how did that work? >> well, they would infiltrate the ranks of citizens of the naacp. it was really an arm of white segry gagsist who would determine at all cost to prevent any sort of integration. >> reporter: through a source, mitchell got his hands on more than 2300 pages of sealed sovereignty commission files and found that ncaacp leader had been a major target. the commission's agents, some of them african american, recorded his movements, important trying the world war ii veteran as an enemy of the state. >> reporter: so he was coming back home from an naacp rally? >> he was >> reporter: in june 19 of 3 he

was shot and killed in the driveway of his home. his wife an children were inside. >> as he stepped forward he got shot in the back. it went through that window, the corner of the window here, went through a wall, hit the refrigerator and landed on the counter >> reporter: his accused murderer was tried twis but both juries deadlocked. pouring through the commission's reports, he made a crucial discovery >> at the same time the same time the city was prosecuting him for the killing, this other commission was assisting the defense trying to get him acquitted. >> reporter: mitchell persuaded beckwith to give him an interview. the chat lasted six hours with what mitchell said was hate-filled rhetoric >> he walks me out to the car and says, if you write negative things about white caucasian christians, god will punish you.

if he doesn't, several individuals will do it for him >> reporter: his story ran and prompted witnesses to come forward. his brother was sceptical about mitchell's work >> i thought it was some white boy trying to make a name for himself. back in those days no white boy was speaking for us. he was one of the few whites. a love him as a brother and i respect him as a reporter. >> reporter: in 1994 beckwith was convicted of first degree murder. the reporting convicted kkk of killing civil rights leader in 1966. in the 1963 bombing that killed four little girls helped secure a murder conviction against clansman >> reporter: after talking to you he was prosecuted >> yes. he was.

gentleman mitchell is still on the hunt working on a book titled race against time. i can't why that title? >> because time is running out to be able to prosecute these cases. >> reporter: even if no suspects remain, telling the story is just as important. doing justice to history, no matter the risk. >> it has led to an unexpected gift, which is living furiously. i began to look for something greater than me. i'm not that big a deal the reason time is running out to prosecute the cases is because many of his targets and witnesses to the alleged crimes are dying. up next, the latest on the search for secret roomss in king tut's room. plus the sea turtle being nursed back to help with the help of a hyper baric chamber.

we're getting a closer look at how archeologists are looking at how to unlock secrets of king

tut's room. they turned up metal or beganic material that experts think it could be the resting place of his mother. >> we have a theory and we're trying to test it. if i'm right, fantastic. if i'm wrong, i've been doing my job and following the evidence trail and seeing where it leads archeologists were supposed to announce the results of the investigation today. instead they say more scans are needed. the results are now expected the first week of may. hyperbaric chambers are usually used to treat deep sea divers with the bends. now the largest facility of its kind on the west coast is using the modern technical theek to heal an-- technique to heal an ancient animal. >> reporter: he is an unwitting medical pioneer, a hard-shelled four flip erred test subject getting treatment in a setting designed for two-legged types >> we can have a chamber over
