it isn't to his internal organs? >> he had an injury to his torso that actually compromised both the abdominal and the chest cavity, injuring his liver and passing very close to the aorta and skipping the heart by a few millimeters. >> that is difficult. this is a young person, presumably a healthy young person. how will this affect your prognosis for him, what you can predict now? >> that is a good question. the fact that he is young and has a healthy heart. he was in a good condition. he actually has a greater chance that someone at a later age he was in a position to tolerate the hemorrhage and the blood loss more than any other patient would, still the injuries were quite severe and he needed aggressive resuscitation both given the case and after in the intensive care unit. >> i'm slur his family is glad they were able to find you and work with upmc trying to take care of this young man. we will be following up and hoping the best comes from you. thank you. >> thank you. >> on the influences former can olympian credit oscar pistorius, third day on the witness stand. >> rick: stand.lihloirnlings. lori jane gliha has the story. >> firing bullets through a closed bathroom door. ask $. >> that wasn't me laughing but that was my voice saying those words. i think in hindsight my lady make me be upset to hear me say something like that. but to compare a zombie which is a fictional a animated characte, comparing to a human or shooting at a human. >> you said, it's softer than blaze, who else got brains. >> despite pistorius's protests, prosecutor known as a pit bull, comparison to an exploded watermelon, to reeva stein camp'steenkamp'shead. >> i'm going to show you mr. pistorius, the exact same effect as the bullet went into her head. >> on the big screen, the prosecutor suddenly displayed an image of her head. we've blurred the image. pistorius who does not credit appear on why camera, because of courtroom directives. >> i don't have to look at a picture. i was there. >> reporter: pistorius's tearful testimony continued. even the prosecutor called the olympian's actions into question. can as he fired at her out of fear. >> when i realized the scale of what was happening i stopped firing. i was in shock. i don't know if i fired -- >> given your evidence i'll stop you every time now because i've warned you. why are you emotional now now that the questions are difficult. why are you emotional? what happened now? >> hold on, hold on. >> he's emotional my lady. >> he may be emotional but i don't think can you ask him why now. he has been emotional throughout. >> reporter: the prosecutor told pistorius he and his tough questions are not going away. the entire trial could last until the middle of next month. why lori jane gliha, al jazeera. >> who failed alicia rudd? inappropriate behavior between staff and dcs shelter families. "america tonight"'s correspondent lori jane gliha reveals these documents and talks to rol everythingshaolesh. >> i couldn't think. >> why didn't you call the police? >> if my mind went black and i -- blank and went into shock, i wasn't the only one in the family that was around when the notification got to us that rolesha was missing. anybody could have picked up the phone and dialed 911 for me because i wasn't at that time able to do it. >> did anybody else call police?

and you'll get... the inside story ray suarez hosts inside story weekdays at 5 eastern only on al jazeera america >> it is one of the worst things a parent could possibly imagine, learning that your child is seriously ill but imagine the doctors suspect it is the parents causing the illness. it is rare, but it does lap. in massachusetts, parents say they have been wrongly accused but their daughter has been taken away from them for over a year. lisa stark has the story on this complicateissue. >> like many five-year-olds, gabriel loves rockets, wants to play. on this morning, gabriel rarely slows down even as he hauls around a backpack pump that sends a nutritious formula into the tube, another tube drains his intestine. gabriel has mitochondrial disease. >> diseases in which the part of the cell that produces energy for body to use doesn't work properly so the body doesn't make enough energy to keep all the vital functions working. >> but as gabriel who takes dozens of medications a day, some doctors were suspicious and accused his mother of what used to be called munchhausen's by proxy. >> how did you find out? >> said we are filing by dcf. that was not a good way of finding. >> that's the department of children and families. a doctor at boston children's hospital called dcf to report the hilliards for possible medical child abuse. >> medical child abuse is a spectrum, parents because of their anxiety or any other reason, they exaggerate symptoms in children, that's a lot more innocent when the other end of the spectrum where parents induce illness, inject them with things, suffocate them, harm their child in order to get more and more invasive and further medical care. >> when you have a child with a disease that is not diagnosed or poorly understood, the dock torsz can be -- the doctors are suspicious of that, presents a bunch of stims that nobody can explain. >> and the hilliards didn't have one child with complicated medical symptoms, they had two. gabriel's sister bethany. she was diagnosed with mitoco mo chondreaal disease. had a much more severe symptoms, bethany just died short of her credit fifth birthday. unlike his sister, gabriel was born with no apparent million problems. but just a few months after the birth of their daughter, jessica and gabriel were back at the hospital, showing signs of the same illness that killed his sister. jessica hilliard said for some hospitals now that raised a red flag and the charge of medical child abuse. >> it's very difficult to describe exactly how traumatic that was for our family. we could be in the midst of grief of losing our child and accused o of harming one of our children at the same time. it was terrible. >> hilliard said she was investigated by the state not once but twice. the state found the allegations unsupported and the investigations were closed. the second allegation came when they moved gabriel to another hospital. the allegations followed. >> they accused us again. >> medical child abuse cases can be difficult to uncover and to prove. these are often complex medical cases, they are not that common but doctors at any large children's hospital will tell you they've seen them. >> some estimates suggest medical child abuse makes up about 1,000 of the 2.5 million case he of child abuse reported every year but there are no reliable numbers because the abuse could day years to uncover and is often missed. just asked the men who prosecuted one of the nation's notorious cases. that of florida resident kathy bush. her daughter jennifer who seemed constantly sick was 11 when her mom went on trial. >> to show the jury how many days each month the child is in the hospital. >> during the years her child was under treatment kathy bush became a media darling and even attracted the attention of then first lady hillary clinton. who attracted the attention of the country. hospitalizations often coincided with her mother's fundraising events. >> you can see this unbelievable amount of time this child had to spend when realistically there was no medical justification for her being in the hospital at all. >> jessica's abuse only came to light when nurses in two hospitals stepped forward with suspicion about the mother's behavior and her interaction with jennifer. >> we documented 38 surgical procedures, that have been performed on this child. some of them were very serious such as removing parts of the intestine, the gall bladder and things like that. >> systematically overdosed her child with a medication, sentenced to five years in jail. as for jennifer once removed from her mother's care she was found to be perfectly healthy. one of the prosecution star witnesses was pediatrician and harvard physician dr. eli newberger. doctors can report suspicions with not much tangible credit evidence and families will find themselves under intense scrutiny. >> if i'm a doctor at all concerned or suspicious don't i want to err on the side of helping that child? don't i want to report right away? >> this is the dilemma for doctors. the threshold for mandated reporting, where you have to show a suspicion of child abuse to a child protection agent, that threshold has set very low. >> does it need to be? >> it needs to be. >> a case now in the spotlight is a 15-year-old justine ah pellitiere, are doctors reported her parents on suspicion of medical child abuse. the parents and doctors at another hospital insisted that justine needed treatment for mitochondrial disease. massachusetts officials took custody of justine more than a year ago. mother was recently overcome after another failed attempt in court to win her daughter back. >> it's almost never black and white in the complex cases. >> newberger, who now consults on child abuse cases nationwide, says the system is not set up to truly protect children who are being harmed as well as families who have done no harm. >> the overworked child protection workers don't have the time to diligently review this and most importantly they don't have the money much less the will to get independent outside consultation. and as a consequence, tragic errors occur. on both sides. >> as for gabriel, he's still being treated for mitochondrial disease, given the family history of the disease. there's no test for illness so hilliard is still worried she could be under investigation. >> being accused of hurt our children was like a punch in the gut. unfathomable, i was angry and offended that people would look at our dedication and love. there has to be a plild ground leer, we -- middle ground leer. that you can investigate and not totally harm the family. >> so far that is middle ground has been hard to come by. lisa stark, al jazeera boston. >> when we return, an unwelcome guest. iranian diplomat and why he's getting the cold shoulder from some in washington. one that could freeze him out of his next assignment. >> and now a snapshot of stories making history on "america tonight." umass sophomore, comes out as gay. following in the footsteps of jason collins. new set of signals from deep in the indian ocean. officials believe they are inching closer to the aircraft but the batteries are draining. as this goes into the fifth week. president obama returns to fort hood for a memorial are service. specialist ivan lopez shot and killed three, are injuring 16 others before shooting and killing himself. iran's disputed nuclear program. credit ambassador to the united nations nations, in the 1979 hostage crisis. "america tonight"'s sheila macvicar explains. >> how would we feel for example if the taliban had cents osama bin laden to be ambassador to the united nations from afghanistan? >> banning iran's newly appointed ambassador to the united nations from entering the u.s? the senate is are are, student revolutionary movement stormed the american embassy in tehran, holding 50 american diplomats hostage for 444 days. some were beaten and tortured. abu talebbi said he had no role, acted as an occasional interpreter. close why advisor crf crr tleheni. observers call him a moderate. but cruz called him an insult to the united states. >> it is unconscionable that the united states would be forced to host a foreign national who can showed disregard of the status of diplomats when they were stationed in his country. this person is an acknowledged terrorist. >> reporter: the white house also made clear that it didn't welcome iran's pick. >> the u.s. government has informed the government of iran this this potential selection is not viable. >> reporter: the united nations is headquartered in new york and as host nation to the international body the u.s. is required to grant visas to all foreign diplomats. the agreement establishing the u.n. in new york states when visas are required they shall be granted without charge and as prompt reply as possible. there have been previous instances where the u.n. has led the u.s. to let people into the country that it doesn't like. former venezuelan credit president chavez, are president ahmadinejad made eight visits to the u.n. in 2009, libyan president moammar gadhafi, bombing of pan am 103 which killed 189 americans. wars in iraq, u.n. diplomats from those countries have been granted visas. the white house hasn't said how it will act but the controversy comes at a critical time. negotiations of iran's nuclear program led by the united states have just resumed. speaking from vienna, iran's foreign minister says they are not wavering. >> to not allow the group of radicals to determine iran's presence at the united nations, this behavior is unacceptable to us. >> reporter: a spokesman said, there are grounds to deny a form diplomat a visa that is a category which can be broadly interpreted. soarts including experts in international law and the u.n. disagree. next question, who makes the next moaf, joie. >> derailed nuclear talks is that a real risk? >> the iranians have said publicly again today, they support this nomination, the talks in geneva are at a critical stage. there is a lot on the table for iran. remember we are talking about moving more economic sanctions which have really done damage to the iranian economy over the years. >> a good time to bring in our next guest ambassador credit john limbert. appreciate you being there on that subject. what happens with the talks here, is there a real threat to them? >> i don't think so. both sides have made it pretty clear, they want to keep the two thims pretty clear. this iranians are going osay what they are going to say but both sides have been calling these talks productive and positive. now, that's an enormous change. whether was the last time anything involving the u.s. and iran were called either productive or positive? >> but if this is a domestic political issue on iran is credit following had understanding there may be some move here in washington right? >> i would lay very heavy odds this gentleman will never get to new york. >> you think the iranians will withdraw this nomination? >> eventually. i think for example we may simply never answer his application are may just sit there we may never say no but after a certain time, they're going to want a senior person in new york. that person, because of the absence of relations becomes almost like a de facto ambassador. he speaks for iran to the united states. he's not credited to the united states but he's the only are iranian official on are u.s. soil. if someone like surabi come here, he would be toxic. who would listen to him? >> he becomes the story. >> exactly. his own past would get in the way create so much noidz that nobody would pay any attention -- noise that nobody would pay attention owhat he says. >> how did it happen that he became the nominee? certainly they flood this. >> good question. one thing in politics that comes along every so often when you ask the question, what were they thinking? or were they thinking even about it? it could have been a deliberate insult, a stick in the eye. but not at this -- it seems unlikely at this moment with this new engagement that we've had after 35 years with this president, with the two foreign ministers talking to each other. frankly, i think it was a question of obliviousness. they just did it, it was a mistake. >> how could it be? it's such a big part of our history with iran, how could this not have been foremost on someone's mind? >> there are a lot of parts of our history, our shared history in iran that are not big in american minds. for example the coup in the 1950s is very big in iranian minds and not so wi -- so big in our minds. >> exactly. the iranians have no monopoly on something like this. 20 years after the coup sheila that you referred to who did we send as ambassador to iran, a move of great sensitivity. we sent the former head of the cia as ambassador. that's -- that's a very strange message. that you want to send. >> so today going forward the message from both sides at least will be even if we accept that this was some sort of error in judgment, a misstep, a slip, still both sides want to progress. >> i think they made it very clear that they do. and i think we have told the iranians, we've announced this, we didn't say how but we've told the iranians that this was a disappointment, creates great problems for us. >> we used the words, "not viable." >> that's diplo-speak isn't it for he's never going to get here. >> never going to get leer. will they think about the next person sort of positioned for that role? >> it will take time. it will be a matter of always saving face. so i suspect the iranians are not going to withdraw this immediately or as i -- according to some sources i saw, they said we never nominated him anyway. they have good people, they have qualified people in their system and they can probably come up with someone better. >> "america tonight"'s sheila macvicar and ambassador john lembert. thank you for being here. >> in a new york minute. >> make the light. please please please. so many passengers like that. >> ahead in our special series, driven. we follow an immigrant's journey from nepal with a lot of twists and turns. a >> and now we continue ourspecis correspondent chris burry, goes back into a taxi. chris meets one driver whose interest in one american dream landed him behind the wheel, a lawyer by trade in his home country of nepal, now he tells us of his story of success and sacrifice. >> for five years now, are he's been driving a taxi in new york city. one of 13,000 yellow cabs that are as much of the city's features as the manhattan skyline. >> this is the island city. yellow taxi. where you see the iconic picture of new york city, there is a yellow cab and times square definitely. >> like more than 80% of new york's 42,000 taxi drivers, yogish was born in another country. his story begins in a village of nepal, tucked in between india and china. at 16 he was married to a 14-year-old girl. he had never seen her before. >> it was arranged marriage, i didn't know how she looks like. my mother choose her, my mother choose her and i decided i just -- okay you are doing dishes for me, definitely that should be a good decision. >> soon with a wife and two children to support yogish earned his law degree and a master's in psychology. he got trained in katmandu, he yearned for more, ambitious young men are often told, america was athe place to fulfill dreams of nepal. >> is the american dream sort of sold in nepal?

>> doesn't mean anything. >> yogish found fast food jobs. first dunn cin doesn't then subway. >> there was a lot of money in the taxi. >> now 36 years old, yogish has put his own dreams on hold. a well educated lawyer in his own country. fluent in three languages but here he is driving a taxi six days a week so he can send money back to his parents in nepal and save force his children's college education. >> do you make enough money to support your family well?

oh my god. that person hit me. >> he gets out, no significant damage, no one hurt. a typical day at the office. his english is good but yogish speaks in his native nepali, and i writes a column for new york's nepali newspaper. he faces frustration. >> when they come here they don't get their own level of respect from the people. and here is the crisis of identity. they just miss their identity. it is a big pond and are small fish. i think that is the thing they're depressed and they're trying to get something better and it's not easy here. >> but if yogish has any regrets trading his life as a lawyer in nepal for front seat of a taxi in new york, he keeps them to himself. >> i enjoy this job. one should drive credit a cab in new york city once in their life. i love the people who are living here, they're really nice and some are crazy and really, i enjoy staying with them. >> yogish has no plans to become an american citizen for fear he would lose many of his rights back in nepal and once his kids go to college yogish and his family plan to return. >> why do you want to return? >> i warrant to do something good for my country. i want a country with them. >> so for this taxi driver a lawyer by trade chasing the american dream has been a bumpy ride. are like so many ambitious and educated immigrants, he arrived here with good hopes for the future, he settled for something else but he's satisfied with the compromise. >> whatever i get in my life, i accept it, i never complain about my life because i know credit there are going to be chances when you worry about these things. whatever it comes, i cannot be a great man in america still i'm a taxi driver from where i can learn so many things. >> chris burry, al jazeera, new york. >> and we can learn from yagish too. san francisco, what the journey to america can mean. >> what made it good for you becoming a citizen?
