ohio primary. >> i'm not worried about that. if we win in ohio, we'll get all the delegates anyway. >> reporter: christie has had to learn patience as for months his campaign teetered on the edge of irrelevancy while distancing himself from a scandal back home. >> listen, the stuff that happened in new jersey, the bridge stuff matures you. hen you take that level of abuse and then you come out the other side of it fine, you're a much better office holder. >> reporter: the ranks of christie's republican rivals shrank by one today when lindsey graham dropped out. maurice, graham took credit for persuading republicans in this race to be more willing than they were before to send ground troops to syria to fight isis. >> major garrett in new hampshire tonight. thank you. we are getting a chilling look tonight at life for some victims of boko haram, the isis-linked terrorists in africa who kidnapped hundreds of nigerian school girls last year. a new report says the group killed 1,000 people in just the past two months. debora patta reports from cameroon tonight where a woman freed from captivity but whose

ordeal is far from over. >> reporter: aisha musa has been living in a crowded refugee camp for seven months. she survives by selling corn meal at the local market. musa was kidnapped by boko haram militants. they killed her family and forced her at gunpoint to become a jihadi bride. "they show you a gun," she said, "and then whatever they say, you have to follow their commands." she told us her captor would lock her in during the day. at night he would rape her. "he would go on operations and kill people," she said, "and then come home and force me to be with him." musa was rescued by the cameroon military, but the worst of her ordeal was finding out she was pregnant by her rapist. she told us, "i am not enjoying that i have a baby from a boko haram man."

but she is resigned and there are moments of tenderness. her story is not unusual. boko haram has captured hundreds of girls, the most infamous the over 200 chibok schoolgirls kidnapped more than 18 months ago. musa never saw the chibok girls but often heard the fighters speak of them. like many of the other girls here, they too were forced to marry the militants. and in a double injustice, many are now stigmatized by their community. girls like musa are regarded as spoiled goods, the baby a very public reminder of a cruel and unfair shame. debora patta, cbs news, minawao, cameroon. aaa said today that for the first time since 2009 the average price of gas nationwide is below $2 a gallon, about 42

cents cheaper than a year ago. a report out today points to a growing danger on the roads, drowsy drivers. those leaving the night shift could be an accident waiting to happen. here's anna werner. >> reporter: this man just came off a night shift. watch the video on the left as he veers all over the road. nearly half the night shift workers tested nearly crashed. dr. charles czeisler worked on the study. >> they were crossing over the middle line. they were having trouble staying in their lane. more than 40% of the drives had to be terminated because it was judged to be unsafe. >> reporter: more than half the workers tested said they nodded off behind the wheel at least once a week on their way home, and they did no better in the test. >> they knew they were being watched, yet even in that context they couldn't stay awake while they were driving in a simulation of their commute home from work. >> reporter: dallas-area convenience store manager shariq khan starts work at 11:00 p.m.

and works through the night. >> sometimes when i get off of my job, when i drive back home, i feel like i'm falling asleep. >> reporter: he believes the lack of sleep led to him having a couple minor accidents. researchers suggest night shift workers like khan skip driving and find another way home, but his area lacks public transportation. >> there's no alternative. there's no bus or no train service there. and i can't afford to have a taxi every day. >> reporter: researchers say night shift workers are fighting their own natural sleep patterns and they can't sleep as well during the day no matter how much they try. they lose about two hours of sleep a day, and maurice, after a few days, they've lost the equivalent of a whole night's sleep. >> okay. anna werner, thank you. from victory to defeat in about two minutes. the story behind the miss universe mix-up. "star wars" did even better than expected at the box office. and meet a star in sheep's

and meet a star in sheep's clothing. oh no... (under his breath) hey man! hey peter. (unenthusiastic) oh... ha ha ha! joanne? is that you? it's me... you don't look a day over 70. am i right? jingle jingle. if you're peter pan, you stay young forever. it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. ♪ you make me feel so young... it's what you do. ♪ you make me feel ♪ so spring has sprung.

in the end, the right contestant ended up with the crown, but many felt the host earned himself a dunce cap. mireya villarreal fills us in on the confusion at the miss universe pageant. >> colombia! >> reporter: it's the moment every pageant contestant dreams of. >> i have to apologize. the first runner-up is colombia. miss universe 2015 is philippines! >> reporter: but for miss colombia, a moment that should have been filled with joy and celebration turned into confusion and awkwardness when host steve harvey realized he crowned the wrong winner. >> it was my mistake.

>> reporter: but steve harvey said the reason for his confusion was how the names were listed on the card. after the show he apologized again. >> i made a mistake. i read the name on the card. >> reporter: to add insult to injury, when he posted an apology on social media, he misspelled philippines. and colombia. critics went online to skewer harvey. pageant coordinators put out a statement saying, "unfortunately a live telecast means human error can come into play." miss colombia took her loss graciously. >> everything happens for a reason, so i'm happy. >> reporter: for miss philippines, the real miss universe, the crowning moment will be best remembered as one of steve harvey's biggest blunders. >> it's a very non-traditional crowning moment, isn't it? it's very 2015.

>> reporter: the ratings for this year's pageant broadcast had over a million fewer viewers than the last broadcast, and maurice, a cbs officer for the pageant actually told cbs radio that they would absolutely have harvey back for the 2016 pageant, saying the world would forgive and forget. >> okay, mireya, thank you very much tonight. well, in a moment the nfl doles out punishment for a game filled with rough play.

today the nfl suspended new york giants wide receiver odell beckham, jr., for one game.

he was whistled for three personal fouls yesterday, including this vicious helmet-to-helmet hit on carolina panthers' cornerback josh norman. the league said beckham placed opponents at unnecessary risk of injury. "star wars" fans were out in force over the weekend. the sci-fi adventure took in more than half a billion dollars worldwide, $248 million of that was in the u.s. and canada where it broke the opening weekend record set this year by "jurassic world." and we'll be right back. ,,,,,,,,

we have quite a yarn to end the broadcast, and it's spun by jim axelrod. [ rooster crowing ] >> reporter: on a bucolic farm just outside burlington, vermont, lives a sheep named sweet pea. she really is so sweet. sweet pea's adopted parents, john and jen churchman have a give- and-take relationship with the land. they saved her life. she changed theirs. >> we're very grateful for all of this. it's very surreal. >> sweet pea, how you doing? >> reporter: when sweet pea developed an infection last winter, jen and john described the touch-and-go on facebook. so when you posted that sweet

pea was in trouble, your followers must have been quite worked up about this. >> they were. they wanted updates all the time. >> this is prem. this is sunny. >> reporter: the churchmans brought sweet pea up to their house with barn-mates violet, sunny and prem to keep her company and to celebrate when she got better. >> we started about -- we would bring the others up for a party. >> someone said, if they do that it's going to be a sheepover. >> we were playing with this and people on facebook said, you have to write a book. >> reporter: they self-published 4,000 copies of "the sheepover." john went to a nearby bookstore, the "flying pig," to see if he could drum up any interest. >> i've been in this business a long time, and i had never seen anything quite like it. >> reporter: the store's owner was mesmerized by john's photographs. >> there's nothing with this collage photographic style that i've seen in the children's book world. so i think it's groundbreaking.

>> reporter: when she blogged a review, a big-time book agent, brenda bowen, didn't waste a second. >> it's granular level rare. >> never happens. >> rarely to never, yes. >> reporter: so now john and jen churchman are farmers and authors. >> we have three books right now, but we have ten more behind that that are ready to be in production. >> reporter: with every one of their 18 sheep a potential story, wool is no longer the most valuable product coming out of their pen. jim axelrod, cbs news, essex, vermont. >> and that is the "overnight news" for this tuesday. for some of you, the news continues. for others, check back with us a little bit later for the morning nows and "cbs morning news." from the broadcast center in new york city, i'm maurice dubois. -- captions by vitac -- www.vitac.com

this is the "cbs overnight news." >> welcome to the "overnight news." murder charges have been filed in las vegas against a woman who drove her car on a curb. one person was killed, dozens of others injured. police don't have a motive, but the suspect is being held without bail. john blackstone reports. >> reporter: the usually busy las vegas strip was crowded instead with emergency vehicles after the 1996 model oldsmobile deliberately plowed into pedestrians on the sidewalk.

antonio had just stepped out of the casino when the car sped past. >> people were bouncing off the front of the car. you could hear it. the windshield was smashed. she rode on the sidewalk and accelerated and just kept mowing everyone down. >> reporter: soon after police say 24-year-old lakeisha halloway pulled into a casino parking lot and told the valet to call 911. >> it looked like she wasn't even trying to stop the car. she had both of her hands on the wheel and was looking straight forward. there were men running after her trying to stop the vehicle, and they couldn't get to her. >> good morning, everybody. >> reporter: clark county sheriff joe lombardo doesn't think this was an act of terror but still can't rule it out. >> as far as terrorism, we don't know what the intent was behind it, and we don't know enough of her background to make that determination. we have not had the time or the luxury to get through all those investigative leads yet. >> reporter: lombardo says holloway came to las vegas from oregon about a week ago and had been living in her car with her 3-year-old child, who was also in the vehicle as she ran people down. >> she did not demonstrate signs

of being under the influence of alcohol, but we had a drug recognition expert respond to the scene and determine that he believed she to be under some sort of stimulant. >> reporter: investigators have not yet determined a motive for this unusual attack. as might be expected here on the las vegas strip, maurice, all 35 of the injured were visitors coming from several states as well as canada and mexico. also in las vegas, a different type of tragedy. this one at the miss universe pageant, on a live show being watched by millions around the world. host steve harvey announced the winner, and he got it wrong. it was an awkward moment for the winner, the runner-up and the entire pageant. nischelle turner was backstage after the mix-up. >> it's not the biggest mistake in the universe but probably the biggest flub in the history of

miss universe. imagine this, seconds ticking down on the end of the live broadcast and everyone is trying to figure out how to tell the announced winner that she's actually first runner-up. >> miss universe 2015 is -- colombia! [ applause ] >> reporter: for about 2 1/2 minutes, she was the reigning queen of miss universe, until host steve harvey returned and said this. >> i have to apologize. the first runner-up is colombia. miss universe 2015 is philippines. >> reporter: the actual winner appeared stunned. for more than a minute, those on stage seemed at a loss for what to do next.

host harvey quickly admitted his error. >> i will take responsibility for this. it was my mistake. it was on the card. >> reporter: unfortunately, it wasn't harvey's only mistake of the night. he tweeted, i wa -- he misspell philippines and colombia. what could be seen as a final indignity, the crown was taken to miss colombia and barely made it to miss philippines' head before cutting to the final credits. >> so very non-traditional crowning, isn't it? >> yes. very 2015. >> reporter: the miss universe organization issued a statement.

>> just wow. i was a preliminary judge for this year's pageant, so i did get to see the inner workings and got to see just how seriously these ladies take this contest. i tell you what, last night it was craziness inside the arena, as well. the crowd was booing. people wouldn't leave, despite repeated apologies from the p.a. system and asking everyone to leave. they just didn't want to see the end of it. a funeral will be held the day after christmas for the young hero who shielded three friends from gunfire when they sound themselves in the middle of a gang war. he died in the cross fire, his friends weren't hurt, but the whole city of knoxville is fighting back tears. david begnaud reports now from the football field where the young man was a star. >> reporter: on this football field in knoxville, tennessee, he was a sophomore standout. the week before he was killed, he went to a stop the violence

rally with his mother. this morning, people around the country are hailing her son a hero. >> it's part of me that want to be angry, but i just can't. >> reporter: because you're so proud of what he did? >> yes. >> reporter: president obama tweeted -- >> reporter: his story has dominated social media. kimberly in california tweeted -- >> reporter: how does that make you feel? >> it made me feel like, wow, you're doing your job as a mother. >> reporter: knoxville police say he was playing video games with friends when he stepped outside to talk to a group of girls and got caught in the middle of gang gunfire. >> he jumped on top of three girls to shield them -- sorry.

to shield them from the shooters. >> reporter: do you wonder "why my child?" >> yes. >> reporter: what do you say to those gang members that shot your son? >> stop the violence. he asked me one time, what am i going to do? what is it in it for me? i said your time is coming. when his seem came, the angels came down and took my baby to heaven. i know they did. and he's looking down smiling, because he made an impact on the whole world. >> reporter: there were five gang members who all fired at him, according to police. one was killed by another gang member. another is in jail this morning and police are looking for the sooe ro three others. >> the "cbs overnight news" will be right back. olay regenerist

an lt is apple is the biggest and richest company in the world. there's a battle over the encryption used in apple products. the debate over companies hiding profits overseas and the challenges of doing business in china. apple is also notoriously secretive. but charlie rose was invited into apple headquarters for "60 minutes." >> go. >> thank you. thank you. it's been an incredible year for apple. tim cook has been running apple for the past four years. but for most of the 15 years before that -- >> we had some real revolutionary products.

>> reporter: the stage belonged to apple's late co-founder steve jobs. >> we're going to make history together today. >> reporter: he transformed the computer from a cumbersome machine into the most sleek consumer product of all-time. the iphone is 12,000 times more powerful than the original mcintosh and next year it will have sold 1 billion units. following steve jobs was one of the most challenging successions imaginable. a daunting responsible for the man he hand picked, tim cook. >> i have never met anyone on the face of the earth like him before. >> reporter: never met anyone on the face of the earth like him if >> no, not one person. >> reporter: not one? >> who had this incredible and canny ability to see around the corner, who had this relentless, driving force for perfection. >> reporter: the spirit of steve jobs hovers over apple.

he was a founder like no other. a volatile visionary capable of creates products for people before they even knew it. cook is a passionate engineer from alabama. on the apple campus, employees still talk about steve jobs in the same way that tim cook does. >> it's a bar of excellence that good isn't good enough, it has to be great. steve used to say insanely great. >> reporter: you believe you can do things other companies can't do? >> we do, and we have, fortunately. >> reporter: it begins on the apple campus at 9:00 a.m. every monday morning at the executive team meeting. someone said go in this room and you'll find the brains of apple. is this the place? >> no. >> reporter: attendance is mandatory. if you are in the room, you are one of the most important people at apple. they wouldn't let us attend the

meeting, but they were eager to tell us what they liked so much about their company. that's jeff williams, officially named the new chief operating officer this week. and that's eddie cue, he is the guy who helped create i tunes. >> it's amazing to work at a place where you're building products that everybody in the world uses, whether it's a 2-year-old or a 100-year-old. they get to experience the products that we're building, and that's amazing. >> reporter: is the dna of steve jobs baked deeply into everything? >> it is,'9" is. this is steve's company. this is still steve's company. it was born that way, it's still that way. so his spirit, i think, will always be the dna of this company. >> reporter: and if there was anyone at apple who comes close to sharing jobs' dna, it would be this man, apple's chief design officer. he's considered by many at apple

to be the most important person at the company. every apple device on the market today was either created or inspired by this reserved and polite son of a british silver smith. we met him in his design studio, but we were only allowed to seal so much. what's interesting in this room is that i see these covers over some of these desks. why is that? >> so you can't see what's underneath. >> reporter: meaning if i could see what's underneath it, i would know where the future is of apple. >> you would know what we're working on next. so that's one of the reasons that it's extraordinarily rare that people come into the design studio. >> reporter: that's why you don't like people in this room, period? >> that's right. we don't like people in this room, period. >> reporter: his team of 22

designers are a very close group. in 15 years, only two have left the company. we noticed that his studio is quiet and looks a lot like an apple store. no coincidence, he designed both around his signature wooden tables. here he and his team create prototypes of future products before the specifications are sent overseas to be manufactured with. the iphone 6 and 6 plus, the design team made 10 different sized models before deciding which worked best. >> we chose these two because partly they just felt -- they felt right. they somehow -- not from a tactile point of view, but just emotionally, it felt like a good size. >> reporter: do you do this about every product, this amount of dedication to emotional

context? >> this is the tip of the iceberg, because we found the different textures considerably -- what it's like to hold it, what it's like to feel it. so the only way that we know how to resolve an address and develop all of those issues is to make models, is to make prototypes. >> reporter: he showed us how he prototyped the apple watch. it begins with a sketch of the watch casing, then it's transformed into a three dimension al electronic blueprint, then sent to a cnc machine. >> the cutter that you can see there in this cnc machine is now machining incredibly accurately the form, the back of the watch.

and all of the tiniest details, as well. >> reporter: once it's been carved, the prototype of the watch casing is sanded and polished by hand by veteran craftsman. his team overseas every design detail, including testing hundreds of different shades of blues and yellows. >> all of these things, if we manage to get them right, you sort of sense that it's authentic, really thoughtfully conceived object. >> reporter: he described a process that comes next, turning a prototype into a working product requires a high level of complex engineering. when he wanted to make the nooe mac book, he worked with apple's head of hardware engineering to create a battery powerful enough

to last all day but also small enough to fit into the slim cased design. >> every tenth of a millimeter in our product is sacred. with this design, it involved mechanical designers, tool makers, chemists, and software engineers to design a pack to fit within the surfaces of the product but still work reliably. >> reporter: one of the most complex engineering challenges involves the iphone camera, the most used feature of any apple product. that's the entire camera you're looking at in my hand. how many parts are in here? >> there's over 200 separate individual parts in that one module there. >> reporter: graham is in charge of a team of 800 engineers and other specialists dedicated solely to the camera. he showed us a microsuspension system that steadies the camera

when your hand shakes. >> this whole auto focus motor here is suspended on four wires, less than half oh a human hair's width and that moves it in x and y. so that allows us to stabilize for the hand shake. >> reporter: in the camera lab, engineers calibrate the camera to perform in any type of lighting. >> you have bright, bright noon and this you go, sunset now. there we go. so there's different types of quality of lighting from morning, bright sunshine, the noon daylight, and then finally sunset. we can simulate all of those here. so believe it or not, to capture one image, there's 24 billion operations going on, just for one picture. >> we'll have part two of charlie's report on apple

let's get these dayquil liquid gels and go. but these liquid gels are new. mucinex fast max. it's the same difference. this one is max strength and fights mucus. mucinex fast max. the only cold and flu liquid gel that's max-strength and fights mucus. let's end this. olympic champion mateas the myer crashed this week in italy, breaking two vertebrae in his back but could have been much worse. he was wearing a new airbag system, and it was the first time one inflated during a world cup event. ka tessa brewer has the details. >> reporter: that fracture of

the second, that technology kicked into gear when needed most, leaving him in much better shape than anyone who saw the fall expected. his world cup run came to an unexpected end after he flipped, flew, and crashed his way past the finish line saturday. what most people didn't realize is during the fall, an intricate safety system was at work, an airbag system activated only during falls. the technology has been in development for falls, but only recently have a handful of athletes started wearing them. >> it's not as big as an airbag in your car. >> reporter: he helped test the new wearable vests by the italian maker. he says for athletes who measure success by the millisecond, s e

safety gear isn't always a top priority. >> it's little bulkier but it's easy to maneuver in it. >> reporter: the airbags are controlled by sensors that detect when a skier abruptly changes position but can distinguish between a jump and a fall. 808 injuries were recorded over the last nine seasons of alpine competition. more than 16% of those involved the head, neck, and shoulders. downhill racing is one of the latest sports to embrace the technology, following in the footsteps of other high speed sports including motorcycle racing. it's a technology insiders say soon will be widespread. >> it's gone from almost science fiction level to reality in just a few years. and maybe in just another year or so it will be something you can walk into a store and buy.

>> the "cbs overnight news" will be right back. ,,,,,,,,,,,,,,,,
