hello i'm don lemmon.

>> does bob durham think that the bobby bales he knows could be capable of this action? >> reporter: he says he absolutely cannot fathom how this possibly could have happened. he said the man he knew was a caring young man who he knew through adulthood and when he worked in the business world and

then went to the military after 9/11. he said that if something somehow caused him to snap, for example, no one knows what happened, he said if doctors are able to find out and get him to understand in actuality that children and women had been killed, that he doesn't think his friend, sergeant bales, would ever be able to come to grips with that. don? >> the last time he spoke with him was back in december. it's been fairly recently, correct? >> reporter: that's right. he called him because -- sergeant bales called mr. durham from afghanistan to console mr. durham about the loss of his own father. and so he felt very badly about it. he said they still have a very special bond. he's close to sergeant bales' entire family.

here's part of what he told me. >> i love the guy. he's a part of my family. he's been -- i've known him since the day he was born. it crushed me. it crushed me. regardless of what happened, bobby has been changed forever. if the bobby that i knew ever gets well, comes back to it and realizes what has happened, and realizes that children and women were killed, i don't think he can live with it. he'll never be the same. and he's such a great person. that crushes me. i don't know.

>> susan, he must have a lot of questions of his own about what exactly did happen. >> reporter: that's right. they are some of the same questions a lot of people had. for example, he didn't know about this injury that he had where sergeant bales lost part of one of his foot in an explosion overseas. he also didn't know about this apparent brain injury that he suffered. so he wants to know like so many other people do, if he had these injuries, why was he sent back on active duty? he's looking for answers like everyone else. >> cnn's susan candiotti. susan, thank you very much for that. coming up tonight on cnn, a man who says he was held in iraq for months. we'll get the latest on him. a u.s. army member, as a matter of fact. and also, a teenager shot to death while walking in a florida gated community. the admitted shooter here, the

shocking. >> i don't know why this man has not been arrested. >> that's the first thing you said to me. and you're a former prosecutor. >> exactly. i'm a defense attorney now, but i can look at a situation and say, every report has told us this young man was unarmed. now we hear the tapes and what do the police dispatchers say to george zimmerman? do not follow him. we don't need you to do that. he was given strict instructions to stop following this young man. the police will investigate. instead, he continues to follow him, and this poor child ends up dead. >> people are saying, we don't know who it is on the 911 call. but after the shots, there are no more cries for help. >> ask yourself this, one guy has a gun, and one guy doesn't have a gun. who do you think is yelling for help? this young man goes to the store to buy skittles for his brother and he's shot dead because he looks suspicious? what does that mean, really?

>> you've worked these cases. why hasn't he been arrested? >> i would love to know. i have no idea. i can't think of why he has not been arrested. sometimes if it's a who done it murder case, you don't want to arrest too fast, but here we know who done it. >> what i'm getting at, do you think it's fishy? is there something fishy going on that you believe? >> it doesn't pass the smell test. this is the same mind, the defendant i'm talking about, zimmerman, who had charges against him dropped when he committed violence against the police. >> this neighborhood watch captain had a gun and none of this would have happened if he had not approached trayvon martin. you said he was sold by theed 11 operator not to approach. isn't that a big factor? where they said we told you not to. >> of course it is, because it goes to intent.

every crime you have to have an action and an intention. and this shows the intent of zimmerman, the defendant, the shooter. he's not a defendant yet, excuse me. he should be a defendant, but he's not yet. that shows you his intent. he was looking for a fight. he went after this young man, even after the 911 dispatcher said do not follow him. >> that was holly hughes. meantime, let's talk about politics now. the republican presidential hopefuls have been out and about. rick santorum had seven events scheduled today in missouri and illinois and didn't hold back this morning in his criticism of mitt romney. >> he gives away that issue. he put forward the bill that was the model for obama care and then advocated that at the federal level. and then denied that he did it. not only was his policies bad, you can't trust him to tell the

truth about what he advocates. >> mitt romney wrapped up a quick spring through puerto rico today, then headed to illinois. he said he's optimistic about a win in puerto rico. illinois will hold its primary tuesday. a developing story out of iraq. an official confirms the united nations has transferred a u.s. citizen to the embassy in baghdad. how he got to iraq and where he's been is raising a whole lot of questions. earlier today, a man identified by the name of randy michaels met with reporters. he did not provide his name but said he deployed to iraq in 2003. which would lead you to believe he's a member of to u.s. military. later he said he moved into a civilian job and was taken hostage last year. [ speaking foreign language ]

>> i was taken inside baghdad and have been kept around different locations within the city. it was explained to me that my release has been for more of humanitarian reasons. >> his identification card was also shown to reporters. now the pentagon is investigating all of this, but a defense department official says to the best of their knowledge, no active u.s. duty military personnel missing had been missing in iraq. we'll follow up for you. some of those who are forced into the sex trade are trafficked across international boarders on commercial airlines. one flight attendant said that people who do her job can be the first line of defense to fight human trafficking. and she's doing just that. her story is next on cnn. weak, w aveeno nourish+ strengthen. active naturals wheat formulas restore strength

a nazi prison guard convicted as an accessory to the murder of 27,000 jews has died. the 91-year-old was free while appealing his conviction and died today in a nursing home in southern germany. he was a retired ohio auto worker when accused of being ivan the terrible. he was sent back to the u.s. when another person was found to be the guard. last year he was convicted again for his involvement at a world war ii death camp in poland. smuggling people into slavery often involves crossing boarders, traveling to far places. that means the first people off to see signs of human trafficking are flight

attendants. >> who are the victims? >> reporter: she's from the czech republic. >> i was grabbed off the streets and drugged, beaten and raped by more men than i could count. >> reporter: she says she was 16 when she was trafficked into the sex trade. 800,000 victims are trafficked across international boarders each year. many are brought from far away countries, flying under the radar into the united states. >> i was boarding a flight in london, and these two young kids come over to me and say, can you help us get this girl to dulles airport? they said, someone has handed her off to us, and she's traveling from mongolia and speaks no english.

>> reporter: sandra has been a flight attendant for 25 years. >> on a flight from costa rica to miami, a man got on a flight with a little girl 9 years old. she seemed quite scared. >> reporter: over the years they've seen things on flights that didn't seem right. but back then few people knew much about human trafficking. >> this young boy gets on and he's got a day-old baby. the baby still had the umbilical cord. he had two diapers in his pocket and one bottle. i ran off the plane and called the police and i said, please, come here. i'm sure this baby has been either kidnapped or stolen. their response to me was, we're not getting involved. >> reporter: she says she and her colleagues and the airline industry are the first people to come into contact with victims of trafficking who are flying into the country. she also says they should

believe the first line of defense. >> the only way that i can help is by alerting the flight attendants, training the flight attendants, telling them what's going on. >> reporter: that's just what she did. she partnered with the nonprofit organization, innocence at risk. they created comprehensive training for flight attendants. this week, airline workers are learning how to spot traffickers, what behaviors to look for and what to do about it. wendy hogue has been a flight attendant for 36 years. she attended nancy's training and learned how to deal with suspicious passengers. >> to go up and just start having some small talk. is this your son? where are you going, business or pleasure? and to just feel it, which is what flight attendants do. >> reporter: exactly why sandra was determined to lead the charge.

you know what that means. it's time for "night mysteries." our extreme dive is coming up, and undoubtedly, there are mysteries hidden. but jacqui jeras has a couple of other mysteries. including one that we may have discovered a new ancestor. does this change history? >> it might change the process. we're looking at evolution here. there are two important parts to this. the first one is exciting, that potentially scientists have discovered a new species of humans. so they are our relatives but don't come from modern man. this the what they may have looked like, and they're being called the red deer cave people. they were found in china and they got that name because they

like to eat a lot of deer meat. and they have some common features with common man and some others that are totally unrelated to any other members in the human evolution tree. let's talk about those features. they had prominent brow ridges, thick skull bones, flat upper faces and broad noses. the jaws jutted out and the cheekbones flared out widely, and that would create space for larger chewing muscles. the second part is how young they were, surprisingly young. this dates back to between 14,000 and 11,500 years ago. so that's like the end of the ice age. while that might sound old, that's actually very young, and we're talking about the youngest population ever to be found anywhere in the world that doesn't fit within the range of modern human. >> really? >> yeah. >> so when they say there's nothing new under the sun, maybe not so.

>> they probably walked the earth at the same time as early chinese farmers. there are going to be some dna testing to find out if this is a hybrid species. >> maybe it's just a link we don't know about. we don't know everything. >> there's a lot we don't know, especially about evolution. >> that's why we say it's a mystery. the next mystery involves a box that some say contain the bones of jesus, right? and this went to court to prove authenticity. what happened? >> jesus' brother, james. so we go from evolution to creationism, so to speak. we had to go back ten years to get to the beginning of this. there you can see this is an israeli collector, and he came out in 2002 saying that i have this burial box. it's being hailed as the oldest archaeological link to christ,

and inscribed on it in aramaic, it said james, son of joseph, brother of jesus. but they said, how can you prove this is real? it came down to, he was charged for allegedly leading an international forgery ring. they're saying he faked this whole thing. so it went to court in jerusalem and the ruling came in last week. they basically said they can't tell for sure. it's impossible to rule whether or not it was authentic or fake. >> mystery. >> so we still don't know. >> i love it when octopus and squid -- when the octopus predicted the world cup. now we have this colossal squid that has supervision. so what is this about? >> they're so huge and creepy and there's nothing small when it comes to a giant squid, from their tentacles to 40-foot bodies, but scientists always wondered why their eye is so

big, because they live so deep in the darkest part of the ocean. they had a hard time getting their hands on one of these things. about a year ago, a fisherman caught one, they froze it and now scientists are looking at it. they think they needed to see a big eye to see something so large very far away, which is their predator, the sperm whale. >> i'm don lemon, she's jacqui jeras. cnn's extreme dive starts right now. instantly soothes and revives tired, overworked eyes. and comforts them for up to ten hours. visine® tired eye relief. try now and save $3.

going to make it big versus you got to be kidding me? >> well, you know, everybody likes to think that they've got some sense of that. you know, hiss tore ukly, nobody's that good at it. some are better than others. but that's what makes it fun. >> so you're the other side of this equation. we're seeing people selling their wears and you're a buyer? >> yes. i look for companies to put seed money into. >> tell me how that works. what do you look for? >> well, we look for disruptive technolo technologies. we look for entrepreneurs who bring something to the table that we think could have a great liquidity event in the future. >> i work with a lot of technology companies. they're entrepreneurs and engineers, geeks. they get really excited about the technology, the solution and their idea. they're like wow, look at this great idea. isn't that amazing? they think that's the hard part. as i look at a lot of the young technology startups, i encourage them to think about it as they have to have something just as unique, just as innovative, just as amaing about how they're going to market it as the technology part that they think

is so great. >> america is really built by entrepreneurs. they started pumping the entire industries. that's how we became the leading economy in the world. >> i feel here at south by is step into a conversation because everyone wants to join in and talk. it's like ted and these things like at night where you have the little short bursts of content that generate a lot of ideas, all grouped into one. >> this is how we create the future. the world is changing at a faster pace. being able to adapt is critical. >> we have a lot of things going for us. we're optimistic about america entrepreneurship like this week at this festival. but other nations are getting -- recognizing the secret sauce that has driven america's economy and it is entrepreneurship and they're putting policies in place to make it friendly for entrepreneurs. >> so if you think the world is changing, globalization, increasing competition and

industries are being disrupted, you never get the finished product. you're always like how do i invest myself and play the next curve? >> the men you're about to meet, you have seen him before. remember this. you will know his name for decades to come. i have tweeted out that i think he's one of the smartest men in the world. he just wrote a book called "abundance" which last i checked was number two on "the new york times" best seller list. peter is trained as an engineer, as a medical doctor. he is the founder of the x prize, you know the x prize. they award prizes for solving some of the world's biggest problems. he is co-founder of sing lart university. in recent weeks he has been at ted. he's been a speaker there. then we were at singularity last weekend in los angeles. and now he's here. i have to ask you, peter. while i'm walking around seeing people develop applications and programs and trying to find venture capitalists to fund

them, you know, i sometimes think, boy, it's all a variation on some kind of location, location-based thing that lets you meet other people. for a guy like you who's involved in some of the biggest problems that the world solves, why you are here? >> i'm here because these entrepreneurs that are, if you would, the tinkers and working on all these have the potential to attack some of the world's biggest problems. they're now empowered with technologies, artificial intelligence, robotics, 3-did the printing to do what only governments in large corporations could do before. and i'm here to incentivize and tell people to go out and use the technologies to solve these huge problems because they can take the risks that large companies and governments don't take anymore. >> why is that? >> well, you know, to do a real breakthrough means that you may fail. in fact, i speak about the fact that the day before something is truly a breakthrough, it's a crazy idea. and so a real breakthrough requires taking big risk that's could fail and large companies are worried about the stock prices plummeting. >> their reputation. they don't want to take that risk.

>> they're willing to risk everything for their vision. a lot of them failed. when they succeed, it's a real breakthrough. ♪ >> so any excuse to get to this town, to me, i'm there. ask me, i'm in. >> you know, austin has a great entrepreneurial culture. it has a lot of smart, young, talented people. >> they're not silicon valley. they have an awesome laid back way about themselves and really trying to solve real world problems. >> austin is this remarkably progressive environment that is doing very, very well. there are people that want to live here and people who come and live here from other places because the cost of living is lower than those other places. >> i lived in d.c. i lived in l.a. i love austin by far the most. i pay for my apartment the same amount i paid in l.a. for

sharing a room in a piece of crap apartment with, you know, four people in the college ghetto of ucla. >> it's hard to say if south by could be anywhere else. there are lots of great cities. south by, by itself is a powerful brand and message. but it married so perfectly with austin. in particular, south by is not just about interactive. it's not just about technology. it's about music and film and gaming, all things that are austin's strengths. >> for a community that wants to keep austin weird, south by southwest certainly fits the bill. it has also grown from just music to films and whole team media. so it has become this roll event almost like a sun dance or even the film festival. but it's different than all those three. it's so next generation. it's about the future more so than like the moment. so i don't know. it has an incredible reputation that it built up over the last five years outside. a lot of people have known south by southwest.

but people outside the mainstream, like i remember when my mother learned about the sun dance film festival. that was like in '94. now my mother starts asking questions about like you are going to this south by southwest or something like that? so it's become culturally relevant. it's built itself nicely, man. and that's by not limiting it to one thing. yes, it started with music. then they branched out into film. now if you're involved in web design or multimedia of any sort, there is a place for you here as well. it's kind of like the san diego film, music and online community. >> there are going to be a million bands descended upon austin in a very short period of time. and they are going to be playing in the streets. they're going to be playing at venues. they're going to be playing anywhere where they can get somebody to listen.
