children in afghanistan, while he wore a u.s. army uniform. we have a picture of him as a senior in high school, years before he took his military oath to serve our country. you'll see it in moments. the military brass say that he walked house to house in the middle of the night, opening fire on afghan villages. when it ended, 16 people were dead, and the u.s. mission in afghanistan had been shaken to its core. tonight, cnn's susan candiotti has gotten exclusive access to some of the people who know robert bale the best. susan is standing by for us in ohio. susan, you've been talking to a man who had a special relationship with robert bale. who is the man and how did he know bale? >> reporter: this man's name is bob durham and he goes way back to know this family.

he knew sergeant bale since he was a baby. he said that sergeant bales, when he was a teenager, always took care of mr. durham's very special son. he's a special son because he's severely disabled. even though bales was a popular football player, for example, he wouldn't think twice about take thing young man out, was never embarrassed to be with him, and took good care with him, was a giving person, don. >> 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. head of a neighborhood watch, claims he did it in self-defense. but do 911 calls back him up? that story is next on cnn.

welcome back, everyone. protests in florida tonight over the shooting of an unarmed teen by someone who was supposed to protect the neighborhood. 17-year-old trayvon martin was walking home from a store when a neighborhood watch captain confronted him. he said that the youth looked suspicious, and there are sounds of a possible scuffle on that 911 tape. then a gunshot that killed the young man. police have not charged the shooter, george zimmerman, who claims self-defense. in a conversation with holly hughes, she calls what happened 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. the best part of any great meal?

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. >> when you know what's going to happen and you walk away, you're just as guilty as that guy that's selling them. i don't look away. >> reporter: thelma gutierrez, cnn, san francisco. some researchers say they believe they've discovered a human an sister. that's next. are energy security and economic growth. north america actually has one of the largest oil reserves in the world. a large part of that is oil sands. this resource has the ability to create hundreds of thousands of jobs. at our kearl project in canada, we'll be able to produce these oil sands with the same emissions as many other oils and that's a huge breakthrough. that's good for our country's energy security and our economy.

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.

this is a cnn special report, "extreme dive, 7 miles under water." >> thank you for joining us. it's one of the most dangerous and remote places on earth. it's also the deepest. and in the coming days, james cameron will attempt to get here. he invited us along to show us how he intends to do it. so we went to the south pacific where he has been test diving a high tech submersible. you'll see what he discovers as we take you on an ex-pitiino.

>> that's one small step for man -- >> to other planets. >> lift off of the "atlas 5." >> carrying the latest rover to mars. even when we fantasize about exploring the final problem fear, it's out there somewhere in a galaxy far away. when you look down at our planet, it shows another frontier closer to home. we live on a blue planet, nearly 70% of the earth's surface is water. the oceans have been mapped, tides measured, sea life recorded. but there is one place that remains a mystery. it is the deepest known point on our planet, challenger deep.

located in a jagged scar carved in the mariana trench near guam, it's nearly seven miles down, 36,000 feet deep. need perspective? mt. everest, the tallest point on earth, could fit in the trench with 7,000 feet to spare. it's the last place most people would expect to see a film director leading a scientific expedition. >> i want to get down here and bring it back to people can see what's there. >> to begin, cameron invited us on board a ship used for inspecting oil rigs. i want to talk about the ship we're on board, the mermaid sapphire. >> let's walk this way. >> the ship has been retro fitted into a deep sea

expedition vessel that on this day sits in the solomon sea. on board, cameron is a deep sea explorer. back in los angeles, he is a hollywood heavyweight. director of the two highest grossing films of all time. taking audiences to a distant planet in "avatar" or telling the story of star crossed lovers on "the titanic." his passion for the sea began long before he made movies, when he was just 11 years old he was already making submersibles. he sent the one in this photo into 20 feet of water with a mouse on board. the mouse survived. >> i was just fascinated by the deep ocean and always wondered what was deeper than where people were already going. your childhood imagination if you're a science fiction geek

like me. you imagine what's down there. >> challenger deep is pitch black, at departments with immense pressure, eight tons per square inch. a hostile environment. if you are able to bring back certain organisms, it will show not only what exists at those depths but might help us understand how forms of life can live in extreme environments in other places. >> you are up to speed on this. at these extreme depths, if you give them an energy source, they'll adapt to the pressure. they can give without sunlight. they look completely differently than we look. so this is a glimpse to what alien life forms line like. >> more on that later. >> close it up. >> he will draw on all his experience for the challenger deep dive. >> and there it is. >> and though his movie fans may

not know it, he has plenty of it. more than 30 dives to the "titanic." in his 2005 documentary, a two-mile dive to the sea floor. there was the -- >> i love the ocean. you've got to be heart broken by what's happening down there. >> he was called on to make recommendations to the epa on capping the gulf oil spill. he says it's taken 15 years of experience to build credibility with the scientific community. >> i always have no problem attracting interest of the science community to participate in these projects. because they get publishable science. this isn't like some rich guy building a balloon to fly around the world. >> reporter: cameron, like any experienced explorer, knows

risks come with the territory, and he's well aware of the dangers of those who have gone before him faced. in 1960, jacque picard and don walsh did reach challenger deep. but their window cracked. and with pressure at 16,000 founds per square inch, they feared their end was near. they continued their descent. their submersible landed but hard on the sea floor, stirring up silt that blocked the view. >> they were stuck and were afraid they couldn't get out of the vehicle once they got back to the surface. >> reporter: the crew spent 20 minutes on the sea floor. cameron plans to spend at least six hours. >> so you want to see how we're going to do it? >> let's see it.

>> the sub comes off the deck in this position, goes out, sits in the water, rotates like this and goes like a shot toward the bottom. gets down quick, works on the bottom and comes up quick. >> he calls it deep sea challenger. it took a team of scientists and the national geographic society more than seven years to build a vehicle able to withstand the pressure. >> i think we were most surprised, we thought there are a lot of theories here. maybe this is going to be a pig on the bottom, you know what i mean? but it's not. it dances. it dances beautifully. and you'll see it all operate. we're going to 26,000 feet, we meaning me and the sub, tomorrow afternoon. you're not coming. it's a one seater.

up next, cameron takes us inside deep sea challenger as he heads out on a crucial test dive. >> it's really getting the subin and out of the water is what everyone is most afraid of. >> reporter: it's the dive that will test his years of experience. looking for financial advice. back then, he had something more important to do. he wasn't focused on his future but fortunately, somebody else was. at usaa we provide retirement planning for our military, veterans and their families. now more than ever, it's important to get financial advice from people who share your military values. call now for our free guide and tips on planning for your retirement this tax season. my first car had deer lights on top... a spare tire strapped to the front grill... and the seat was more of a small couch made of green pleather. it was hideous. it was loud. it was my mom and dad's way of forcing abstinence

director james cameron is on a mission to dive to the deepest point on the planet. challenger deep. seven miles straight down into the mariana trench. cameron and a team of scientists specializing in deep dives, along with national geographic, have built an advanced submersible called deep sea challenger to get him there. it weights 12 tons. even though it's on its side, it's 24 feet high. it's powered by lithium batteries and the body is made of a synthetic foam and the

color, cameron calls that kawasaki green. there is a steel sphere inside where he will pilot the sub. >> so this is my window right here. >> and it's designed to withstand the depth's intense pressure and keep cameron alive. >> i basically have a fully redundant, independent life support system. i can live on either side for about 25 hours or combined 50 hours. which is a lot longer than i would want to be in this. >> it's got a camera i can move way out from the sub. >> how do you get a camera at that depth to operate?

>> you have to make it. >> i don't know of any that do. >> they're still a bit finnicy. >> do you have a name for them? >> we call them the mini cams. real clever, huh? >> do you strap yourself in when you go down? >> it's not like you're in a jet where you're getting slammed around. i'm used to clamoring around in this thing. >> but it is like a jet and the cockpit is very small. >> once we get all the gear inside, we have to figure out how to get ourselves in the diving position. i'm going to show you what it takes to get into the actual diving position. >> okay. >> it's a whole process you have to go through. that's it. now i'm home. >> that is your position that

you have to maintain? >> yeah. >> for four hours? >> i'm like this for about ten hours. >> no wonder he has to keep that position. the sphere's internal diameter, just 43 inches. every inch accounted for. >> more oxygen back here. these are life support controls here and here. >> the tour ends so cameron can prepare for a crucial test dive to 26,000 deep, about five miles down. now meet some of the team who will help him get there. >> that's phenomenal pressure. but we have a good team of people. >> this is a dream, absolute dream. >> also on board, mike and andrew, they'll join cameron on the dive. they're named in memory of underwater photographer mike and australian film maker andrew white. both were killed when their

helicopter crashed during a test dive. >> mike degree told me when he was bringing on the project, erica, you've never seen a submersible like this in your life. i'm very excited and now we'll be able to film 3-d in the deep sea, hopefully all the way down to the mariana trench. and we'll be able to see those animals coming right at us. >> the team didn't have to wait long to see what the deep sea had to offer. >> look at that. >> that's amazing. >> from 26,000 feet down, mike hauled in a hand full of large shrimp like anthropods. it could be an entirely new species. >> he says oh, hey, check you out. >> these images were shot by the

landers. but cameron gets behind the lens, as well. >> very intense. >> and given what he's seen so far -- >> he just comes by with his little bristles swarming. and tentacles. >> expectations for the challenger deep dive are high. the crew has been pulling long hours for weeks. fatigue, tough to avoid. >> valuable commodity here getting some sleep. >> the crew soldiers through it all. >> that was the last of the preflight checks. >> but the test dive would have to wait. >> there was some issues with the landers that delayed things going on out here with the dive. tell me what's happening. >> we just had trouble communicating with it.

it's like an underwater telephone. >> minutes turn to hours. night into day. i worry about these kind of like the way you would a teenager, when they learn to drive. most of the time there's nothing to worry about. and in this case, i don't think there's anything to worry about. but in the back of your mind, you keep thinking oh, what is that one time in a million. >> the crew fixed the lander's communication system. the other problem, someone simply forgot to turn on the 3-d camera. >> okay. let's get going. >> few were looking forward to the morning briefing. >> we're going to get the landers back on board. erica, you guys just jump out right now and get on that. >> the meeting ends without a public reprimand. >> these people are self-motivating to a point where they know if they've screwed up and in this case it was just

because of fatigue. you know, there's nothing i can say to them that's going to make them feel any worse or be any better the next time. that takes a while to learn. inside, i might be like, what the -- >> up next, cameron's test dive finally gets under way. >> the challenger is requesting permission to ascend. >> but he runs into a crisis, 20,000 feet down.

cameron has seen doth. >> sometimes the crew gets disheartened when things fail. i said guys, this is the test phase. >> his technologically advanced submersible, years in the making, is ready. and he prepares a crucial test dive. >> first, let's see where we are with everything. >> right now we're looking at a daily briefing. this one is especially critical, because this is the day that cameron will take a dive down to 26,000 feet. this will be the deepest test five that he's done before the deep dive. right now he's just trying to make sure that all systems are in place. >> all right, let's get to it. >> once the briefing ends, the crew readies the sub. cameron anticipates what lies below. >> imagine landing a helicopter with the canopy painted black in the mountains at night, just on instruments. so you've got to come down quite slowly.

>> prelaunch preps are under way. a meticulous process. covering a 70-point checklist. cameron's project manager, david witherspoon. >> we all had a hand in building this submersible, so we all feel responsible. >> talking to cameron there is john garvin, another project manager. the sub is fully pulled out, airbags attached to keep it in position once in the water. the hatch has been lowered and cameron is going to be bolted into the deep sea challenger. garvin narrates the launch. the crane attaches to the lifting point in the middle of the sub. there's a number of tag lines

under high tension in addition to the crane to stop the sub from moving and swinging. when you see the sub first hit the water, the divers will come in and their first job is to uncouple the crane. >> you have to make sure the sub doesn't rotate around quickly. it's about not getting injured. >> when the last airbag is removed, cameron and deep sea challenger begin the descent. >> deep sea challenger, do you copy? >> inside the control room, there's a problem. communication malfunction. >> do you copy? >> copy you loud and clear. >> cameron descends for an hour. then there's another malfunction. >> deep sea challenger advises that he has thruster failure.

>> reporter: cameron continues on. then at 24,000 feet, comes the call no one expects. >> deep sea challenger is requesting permission to ascend, over. >> please proceed. >> cameron aborts the dive. the team readies for him to resurface. crews have attached airbags on to the deepsea challenger to ease it into the correct position. then that crane that you see over there will get ahold of it and lift it back on board. cameron made it to 23,813 feet, a record for a solo manned dive. that is the good news. >> never saw the bottom. >> where do you take from this? >> a lot of this is trial and error. i think we've got a sound ship.

i don't think we should do anything differently. we have to see exactly what the failures are. >> it will be a night of rest. and for cameron, also reflection on himself and his ultimate goal, challenger deep. >> am i an explorer who does films on the side or a film maker who does exploration on the side? to me the rubber meets the road where it's not scripted. the ocean doesn't show up and do its lines. you have to adjust and adapt and be prepared and be prepared to see something new and unknown and react to that. >> some final notes, cameron and his team tried again and reached 26,791 feet or a little more than 8,000 meters. a new record for a solo man dive. they are shooting the entire expedition and they'll release a documentary. now that test dives are done,

they can focus on challenger deep. that dive, weather permits, is expected to be attempted within a week. thank you for joining us. i'm jason carroll. fore! no matter what small business you are in, managing expenses seems to... get in the way. not anymore. ink, the small business card from chase introduces jot an on-the-go expense app made exclusively for ink customers. custom categorize your expenses anywhere. save time and get back to what you love.
