more than 48 hours after two towers of the condo complex came crashing down, at least 159 people remain missing, as crews dig through the rubble, searching for any signs of life. a judge sentences a police officer to 22 1/2 years in prison for murdering george floyd. the question now, could this case change the way officers do their jobs in communities of color? and president biden pledges u.s. support to afghanistan, as the taliban presence in the embattled country increases.

welcome, watching us here in the united states, canada and around the world, i'm kim brunhuber. this is cnn newsroom. search and rescue teams are working through the night searching for survivors after the catastrophic building collapse in the town of surfside near miami. part of the 12-story shamplain towers came crashing down during the early hours of thursday morning, four people are confirmed dead and the where-abouts of 159 others are unknown. it is still not clear what caused the high rise condominium tower to collapse. rescue teams have been facing daunting obstacles, heavy smoke from fires within the building, unstable mountain of rubble, as well as heavy winds and rain. ♪ it is well with my soul.

>> the vigil was held friday evening to remember the lives lost and to pray for those who are unaccounted for. cnn spoke to miami-dade's fire rescue chief who has a message for those awaiting news of their loved ones. >> have hope. there's always hope. i was in haiti, and eight days after we were there, we took a girl out of a collapsed -- you got to have hope. and we're doing everything that we can to bring your family member out alive. >> and that's what so many people are doing. holding on to hope. as the careful search goes on. cnn's natasha chen has more from surfside. >> reporter: we will continue search and rescue because we still have hope that we will find people alive.

>> but that hope is fleeting as crucial hours pass. >> if they are alive down there, like what's going on, like, you know, how afraid are they in there? is there a possibility they're alive? truthfully, look at this mess. what are the chances? >> reporter: officials say about 55 of the 136 units of the 12-story residential building in surfside collapsed early thursday morning. still no clue on a cause. search and rescue crews are working around the clock using heavy machinery, sonar, cameras and specially trained dogs to try to locate the missing in the rubble. >> you get lucky, you find them in a pocket and able to basically by hand remove the rubble. >> reporter: but those efforts are being met with new challenges, fires at the collapse site, as well as rising water and shifting materials. >> it then challenges the integrity of what is still standing there. and then that delicate balance of saving lives while risking

lives. >> reporter: crews are now looking at the license plates of cars in the parking garage to try to determine who was in the building. the residents represented international and cultural mix. >> my brother, wife and children, two, six and nine. losing hope. >> overnight, president biden declared a federal emergency in florida making federal aid available and experts are studying the structure which was undergoing a 40-year certification and determine whether an investigation that could impact building codes is necessary. an attorney for the association of condo residents tells cnn has engineer had conducted an inspection to determine needed repairs but the only work that had started was on the roof. judy spiegle is among the missing. tonight, her husband ketch who was out of town at the time of collapse ander that three adult children are holding out hope. >> i have to be hopeful.

i want to be with her. i love her. >> how, from one second, to the next second, a dramatic change in life, it's unbelievable. >> reporter: the chief of miami-dade fire and rescue tells the families right now to have hope. he also explains that some of the work they're doing may not be seen by us on the ground or even through aerial footage. he says the crews are actually going underneath the rubble, where the basement was, to try and go up into the building that way. all the while dealing with dangerous conditions, like falling debris. natasha chen, cnn, surfside florida. >> now those dangerous conditions are unimaginable, and have been described as even being like the twin towers, and 9/11, flattened buildings, after the haiti earthquake. officials spoke to cnn earlier and described the conditions. >> we have over 300 firefighters, multiple task

forces on-site, in the building, under the building, subterranean and battling it, a massive task force but what is happening is a fire in the building, in the lower floor, between two and three, and also in the garage area, is hindering their efforts to continue search, rescue and hopefully recovery. >> miami-dade fire/rescue has done an exceptional job of keeping this fire under control to the point where we can continue to work safely. now, you might look at it and see the fire has not been extinguished, but we look at it as they have done an excellent job allowing us to continue to work because if they were not doing such a good job, we would be forced off the pile and nobody would have the opportunity for survival. >> those rescue efforts are taking an emotional toll on emergency crews, as they search through the rubble in hopes of finding survivors of the trauma surgeon working in the search told cnn's anderson cooper what they're finding. >> a lot of people, you know,

you think about rubble, and metal, and twisted steel, but we're seeing, you know, stuffed animals, teddy bears, a box of diapers, a child's bunk bed, and we find a lot of pictures and family pictures, and it's a little bit more emotional than going somewhere you know there is no one, and especially with a hurricane, where they had enough warning and had evacuation time and got out, but this you know it happened in the middle of the night and for the first time now i just saw the video and it's pretty -- >> i know there are obviously dogs on-site. there's devices where you, you know, sound devices, you put into rubble. i know in other places, sometimes even, like everybody calls for quiet on the site, just so you can hear, in case anybody is tapping. >> yes, there was, prior to me getting there yesterday, around 1:00 p.m. or so, they did hear some tapping, there was some

noise, and you know, it kept up for a while, and then over the course of the day, they sort of, that dissipated. >> so as teams scour the site hoping to find more survivors, some family members are trying to help and the only way they can, and it comes with a sad realization. >> i received a call from a reporter this morning letting me know that they were taking dna swabs at the surfside community center, and then i heard on the news as well, so we headed over there. and the scene was a bit chaotic. there were people everywhere. it wasn't really organized. then i don't think the rain helped. so they moved us to another location. where it continued to be chaotic. until, you know, we kept asking everyone, where can we get the dna swab. finally, we were able to do that. >> so as they tried to stay positive, pablo rodriguez and other loved ones, the 159 people unaccounted for, helplessly wait

for answers. cnn's nick valencia has their story. >> there's a heaviness here today in surfside. that heaviness comes amidst the uncertainty where family members told us they are not getting much information at all. there are some people holding on to hope but others resigned to the fact they believe, they say, that they're just going to get bad news, and waiting for that news to come. and there are others like soriah cohen whose frustration is bordering on down right outrage. her husband and brother-in-law, brad and gary cohen she says were on the 11th floor asleep at the time of the building collapse. she believes both those two men are still alive but she says time is running out and she says she's embarrassed by the recovery effort here, this is the message that she had for the first responders. >> you shouldn't be allocating your resources, you need to call in other teams to help and you need to do this immediately, every minute that goes by, could be another life. it's not just the life of the person.

my children are going to be orphans. >> her 12-year-old woke up in the morning unable to have breakfast because she couldn't stand to think that her dad was perhaps still alive buried under the rubble and not being able to get help. at this point the reunification center has been moved from about a block away to this hotel behind me where people inside come out and describe about 100 people inside really waiting around for information. earlier in the day, we saw governor desantis come by. he was only inside for roughly 15 minutes before he left. some are being proactive. opting to get some mouth swabs in the case that they need dna to identify bodies pulled from the rubble. nick valencia, cnn, surfside, florida. now, of course, many people are wondering, how this tragedy happened, and if it could have been prevented. earlier, cnn asked that very question to the structural engineer hired to investigate the collapse. he also helped write the inspection guidelines for buildings in florida. here he is.

>> this particular point in time, it's very important not to speculate as far as what caused this building to go down. engineers have a specific routine as to how go about doing a forensic evaluation. and so that's the way it should be approached. the 40-year inspection program that happened since 1974 was certainly intended to prevent something like this from happening. and so nothing really like this has happened, until this has occurred. the thing is, though, that we expect building owners to maintain their buildings. you don't wait 40 years and then start looking for trouble or signs. the buildings themselves are supposed to be maintained according to the way they've been built originally. >> much more to come on cnn,

including details on the sentence handed down for the former police officer convicted of killing george floyd. community reaction ahead. plus the nypd is looking for four people who vandalized the george floyd section in brooklyn. the latest on the man hunt coming up. please stay with us.

the fact that giano will grow up knowing that her father will make a difference in the world but the fact that that she cannot have a sweet 16, she cannot have him walk her down the aisle, she will not be able to have prom with the daddy dance. this is not something realistic. >> that was george floyd's brother reacting to the sentence. the judge on friday gave the former police officer who killed him, derek chauvin was sentenced to 22 1/2 years for second degree unintentional murder, that is greater than the state guidelines but less than the prosecutors requested. chauvin probably won't spend the entire time behind bars. omar jimenez has more on that and more from synapse. >> t-- from minneapolis.

>> 13 months to the day after murdering george floyd, derek chauvin was sentenced. >> the court commits you to the custody of the commissioner of corrections for 270 months. >> 22 1/2 years in prison after the former minneapolis police officer was convicted on charges of second degree unintentional murder, second degree manslaughter and third degree murder. the judge peter cahill wrote in a sentencing memo, mr. chauvin rather than pursuing the mission, treated. in floyd without respect and denied him the dignity owed to all human beings in which he certainly would have extended to a friend or neighbor. the prosecution, capping off an effort for more than a year in the making. >> a police officer is not above the law. and george floyd certainly is not beneath the law. >> during the sentencing hearing, the family expressed the impact george floyd's murder had on them including his 7-year-old daughter giana floyd. >> asked about him all the time. >> his brothers speaking directly to chauvin.

>> why you getting up? why are you staying here? >> and making their plea to the judge. >> the maximum sentence possible. >> chauvin's mother spoke in his defense. never acknowledging the floyd family. instead -- >> derek, i want you to know that i've always believed in your innocence and i will never waiver from that. >> the court found the opposite and for the first time the 45-year-old former police officer addressed the floyd family. >> i want to give my condolences to the floyd family. there's going to be some other information in the future that will be of interest, and i hope things will give you some peace of mind.

thank you. >> outside the courtroom, mixed feelings of celebration and wanting more. >> this is the longest sentence that a police officer has ever been sentenced to in the history of the state of minnesota. but this should not be the exception. >> it's the close of the first chapter in a story that continues, long after nine minutes and 29 seconds impacted the world, and changed it as floyd's daughter has said. >> if you could say anything to your daddy right now, what would it be? >> it would be i miss you and i love you. >> now, 22 1/2 years is the sentence, but he could serve just 15 since here in minnesota, you serve the first two-thirds of your sentence in prison, and then become eligible for supervised release. for the final third. but he's still got two upcoming

federal trials that could add to that, stemming from alleged civil rights violation and also has the opportunity 90 days to appeal this case. especially since the judge denied his request for a new trial, just before the sentencing. that's separate from the appeals process. we reached out to the attorney representing derrick chauv ton see if he had any -- derek chauvin to see if he had any comment on the sentencing and simply responded no comment. cnn, minneapolis. cnn legal analyst and civil rights attorney riva martin joins us now. thanks for being here. george floyd's sister shows the sentence shows police brutality is quote finally being taken seriously. the prosecutor asking for 30 years saying quote it is the beginning of accountability. i know from seeing your reaction from social media that you disagree, you're disappointed with this sentence. why? >> disappointed kim, because when you look at the heinous nature of the crime, if you look at other cases that have been

prosecuted in the state of minnesota, there was justification for this judge doubling the presumptive sentencing, we know the presumptive sentence was anywhere between 12 and 15 years, and the prosecutor presented evidence during his statement of a case in minnesota where there was one aggravating factor and the presumptive time period was actually doubled in that case. and when you look at this case, the judge found four aggravating circumstances, so i think the 30 years that the prosecutors asked for in their pre-sentencing hearing and what they asked for, pre-sentencing motion, i'm sorry and the hearing today, was absolutely justified. the evidence and on precedent set in the state of minnesota. >> is part of the frustration that many black and brown people have been, you know, sentenced for a lot longer for a lot less? >> oh, absolutely. and we heard george floyd's murder make reference to that,

when he gave his victim impact statement. he said look, we don't want a slap on the wrist. we know if there was, roles were reversed in this case, if there were one of us, basically he admitted if there were an african-american defendant, who had been convicted of murder, three counts, they would be, he said, under the jail. so we've seen too many cases where african-americans, latino, people of color, are serving much longer than 22 years in prison, and many times, it's for nonviolent drug charges. so clearly, we should not be dismissive of the fact that this is an historical sentence, and the fact that probably the longest sentence ever for a police officer in the state of minnesota. we don't want to lose sight of that. and clearly, derek chauvin has been held accountable, but nor do we want to overemphasize or suggest that this is somehow the ending of what has been, what we've seen played out in this case and so many other cases, of

the systemic racism that is persuasive in so many police departments across the united states. >> so on that then, which do you think is more likely, that this case, and verdict and sentence will go in some way to deter police from actions like this? or will it do more to hold officers accountable if they do something like that, or neither? >> i think the jury is still out, to be honest you with, there have been officers that have been convicted for murder, and have been convicted, have been sentenced, have served jail time, and yet we continue to see african-americans killed by police at disproportionate rates. police in this country, kill about a thousand people a year. so i don't think we can draw a straight line and conclude that simply because derek chauvin is going to serve 22.5 years, and we should note that in the state of minnesota, he will only serve two-thirds of that time, so about 16 years, that that is going to necessarily deter or

change the culture of policing in this country. we have a real issue in this country when it comes to policing, particularly policing communities of color. >> looking ahead then, what do you think this case, this sentence, might mean for the other three officers accused? >> i think it spells trouble for the other three officers, when those three guilty verdicts were read by the jurors in april, just a couple of months, a month or so ago, i can imagine that those three other defendants were shaking in their boots. they now know that jurors are rejecting their claim that they used the appropriate level of force, that they followed training, that they did not do anything wrong, with respect to how mr. floyd was treated on that day, so, you know, to get those guilty verdicts handed down, and now to have a 22.5 sentence handed down by the judge, i can imagine that those defendants are incredibly

nervous about what the prospects are for them, when they go to trial in march of next year. >> always appreciate your analysis, thank you so much for joining us. >> thanks, kim. after the sninsing hearing, floyd's -- sentencing hearing, floyd's family called on congress to pass the george floyd justice in policing act. president joe biden asked that the measure be approved by the anniversary of floyd's death in may, but it remains in negotiations. he weighed in on chauvin's sentence from the white house. let's listen. >> well, i don't know all the circumstances that were considered, but it seems to me under the guidelines, they seem to be appropriate. >> now, earlier, i spoke with anika buoy, the vice president of the minneapolis naacp and she talked about where the community goes from here, and whether chauvin's lengthy sentence represents a turning point. here she is. >> i think it gives a sense of

accountability and a sense of justice to george floyd's family who we want to send our deepest gratitude, who held strong throughout this slow and steady process of our judicial system. but let's be clear. black people in minneapolis alone, aside from the entire nation, knew that derek chauvin was guilty prior to the murder of george floyd. this is an officer who was part of a police department who has hundreds and hundreds of lives on their hand, right? it is very clear that we know that the minneapolis police department has blood on its hands and derek chauvin's sentencing does not wash it away. >> you can see more of my discussion with minneapolis naacp vice president anika buoy, next hour, right here on cnn. the new york police department is on the hunt for four vandals suspected of a possible hate crime. they believe these individuals were involved directly or indirectly in defacing a george floyd statue in brooklyn on

thursday. floyd's brother had unveiled the 16 foot tall statue for the juneteenth holiday and vandals painted over the face and the base, and stencilled in the words of a neo nazi white supremacist group. new york governor andrew cuomo had a terse message for the vandals. get the held out of our state. still ahead, another night of massive search and rescue operations in florida, two days after a deadly building collapse. we'll bring you an update and hear from people who witnessed the disaster firsthand. plus, some of the theories behind what may have caused the building to collapse. that's just ahead. please do stay with us.

welcome back to all of you watching us here in the united states, canada, and around the world. i'm kim brunhuber. this is cnn newsroom. we're turning now to florida, where four people are confirmed dead and 159 remain unaccounted for, following thursday's condominium tower collapse in miami. rescue teams are relentlessly digging through piles of rubble desperately searching for survivors. we have more from the disaster site and one of the big questions everyone is asking, what caused the building to collapse so suddenly? officials are promising an urgent investigation, but experts say at this stage, it's impossible to pinpoint the cause. right now, we want you to hear from the people who were there on the scene. those who witnessed this disaster, as it unfolded. some were inside the building when it happened. others were just steps away from

parts of the structures that vanished right in front of them. >> it was a really loud clap of thunder. >> it felt like a jet took off above the building. >> the chandelier and the pendant lights were swaying. >> and my husband grabbed me and said what was that, and the whole bedroom was shaking so violently, that honestly, i was prepared for the building to come down. because it was not something stable. it was nothing going on that seemed normal about it. >> really, until we opened the door, we didn't know anything happened to the building. it was intact. i looked to the left, and the apartment to our left was half sheared off. i looked forward, which is where the elevator shaft is and it was just a hole. that was the real thing, at that point, we knew it was a race against time. because i didn't know if the rest of the building was coming down. >> i hear this large, like rumbling noise out of nowhere and i can just see like white

clouds, like just dust coming out, so i told my mom and my sister, we were outside, i told them to start running. we ran. and all we could see was just white dust like thick. >> i looked down the hallway, and there was nothing there. it was just a pile of dust and rubble and paint falling from the ceilings. we went down to the garage in the basement, water was pouring down from the pipes, we realized that we had to get out of there, because staying down there, we could drown. knowing how, what it looked like outside my door, i thought that any minute, we could be that same pile of rubble. >> just don't know why we're here and the rest of the people aren't. >> having gone out to the hallway and seeing that it was mere feet from the wall that my kids were sleeping in, it could have been a very different

scene. i could have walked into the living room checking on them and found that rubble. and it just, i don't think i process it, i'm in that moment but i don't think i really processed what happened. >> the first class action lawsuit has already been filed against the collapsed towers building association. it asserts that the disast c clear -- disaster could have been prevented through the exercise of ordinary care, safety measures and oversights and seeks damages of more than $5 million. what do we know so far about this 40-year-old building. cnn's tom foreman takes a look. >> you're watching what some engineers are calling a classic column failure. what they say they'd expect of a building's key support column giving way. but did that happen here? where local officials say robust inspections are the norm. >> there had not been any concerns. >> this building was constructed

40 years ago, on an ocean front island, the kind of area that engineers have said is too sandy, too close to moving water to be stable. >> this past weekend, there was some water in the garage and it was coming up. >> could a sink hole be to blame? a former fire chief says they're just not common here. >> we don't have sinkholes in south florida. >> a second theory, the whole building was sinking. a study from florida international university showed a gradual sinking of the building, or maybe the site, in the 1990s. experts say this isn't unusual and likely would not have caused the collapse but it could have contributed to another threat. >> the settlement. if the building settles, some areas more than oh, then the column could get pulled in and

cause some distress there. >> pablo rodriguez's mother is missing. he spoke to her the day before the collapse. >> she just told me she had woken up around 3:00, 4:00 in the morning and had heard like some creeking noises. >> but experts would expect other sign, too. >> people in the building would see cracks in their floors. the table would not be flat. things would roll off. >> and yet another theory. >> the building itself. humans and salty air could weaken steel and concrete, the partial chance of a federal building in miami in 1974. >> i've seen up and down the coast hundreds of buildings where you have concrete problems. it could be a building, it could be a dam, or a sea wall. these kind of things happen, if not tended to. >> the concrete roof was being worked on. the building was undergoing improvements as part of a required 40-year review. it is not clear if any of that played a role. but we do know this. the search for survivors goes

on, and so does the hunts for a cause. tom foreman, cnn, washington. >> right now, search and rescue teams are still looking for more survivors but there's been an unexpected hurd until the way. the weather. so let's bring in meteorologist derek van dam. >> i spoke with the mayor of surfside and he was asking for luck in terms of the weather, they haven't had much of that since then. is it looking any better? >> well, we already know that weather has impacted search and rescue operation, halting it briefly on friday morning because of an onshore thundershower that moving onland impacting the surfside region. this is a very summer time environment at the moment, northern hemisphere, southeast florida, a warm unstable environment so it doesn't take much for these thunderstorms to develop. at this specific moment in time, local time, 4:37 in the morning it is mostly clear so no

concerns. surfside 78 degrees. it feels like 81. take note of the easterly wind. that will increase through the course of the day as we get a gradual heating online that creates what we call a sea breeze and we sea the thundershowers become more numerous. you can see the hit or miss nature of the showers that move. in and let's get hyper local, and ability to do that with the radar and move into the surfside region and within the past 30 minutes or so, there was a shower and nothing concerning, this is the type of activity they expect to experience in the next 24 hours and beyond that, because of the transient environment taking place, it doesn't take much to fire off one of these thundershowers and of course, crews can work through rain but they can't work through lightning, that causes all kinds of safety hazards. not to mention these thundershowers that do form often in this part of the world in southeast florida can create what's called gusty winds, a gust front ahead of a thundershower, so any loose standing debris on a standing structure could that remains could be knocked off and impact

the search and rescue missions. and we can't forget some of the gases from the broken gas mains from the building, and winds can distribute and disperse those lethal gases as well and there is a concern, you can see the thundershower activity increasing through the day today. >> so many hazards for the search and rescue crews. thanks for the update. appreciate. all our thoughts are with the victims and their families, and you can help them, you can go to cnn.com/impact and find links there to charitable organizations that have been verified by cnn. well, the u.s. and afghan leaders meet in washington as american troops exit afghanistan in a precarious position, we'll explore what president biden and ghani are saying next. stay with us. our new scented oils give you our best smelling scents. now crafted with more natural ingredients and infused with essential oils that are 100% natural. give us one plug and connect to nature.

the partnership between afghanistan and the united states is not ending.

it's going to be sustained. and our troops may be leaving but support for afghanistan is not ending. >> in moments of great transition, things happen that you would see that with the determination, with unity and with the partnership, we will overcome all odds. >> giving their assessment of what lies ahead once the u.s. troop withdrawal from afghanistan is finished. the leaders met in washington friday as the september 11th deadline draws near but already taliban forces are seizing more and more territory. mattingly has more on, phil mattingly has more on the circumstances surrounding the meeting and what the afghan leader is hoping to achieve. >> the afghanistan president had several messages he wanted to deliver to president biden. obviously, there was no question that the troop pullout, that president biden had already announced was not going to change, no matter what president

ghani put on the table but there is clear need, clear necessity for more u.s. assistance as the u.s. moves through that process. the country's security situation very clearly deteriorating amidst taliban offenses throughout the country particularly in the north. real concerns from u.s. intelligence officials that the country could fall within six months of the u.s. officially departing after september 11th. where things stand right now, the u.s. is not changing and president biden is not moving off of that september deadline making clear the u.s. will continue humanitarian support, will continue its presence at an embassy in kabul, and there will be about 650 u.s. troops there to protect that embassy. but that security situation, that is up to the afghans. whether or not a peace agreement is signed, the u.s. supports it, but that is also up to the afghans. and of course, there is also the big question of those afghanis who helped u.s. forces, u.s. personnel over the course of the last 19 years, the administration still working through that process, as of now,

they have identified a certain group of those individuals who are going through the special visa process, they will be evacuated before the september deadline, to a third country, as they move through that process, how many that will be, and what that third country is, that is still up in the air. but obviously a very complex situation. and the biden administration making very clear, despite the visit in person, from the afghan president, they're not changing their posture on this. all they can offer is help and assistance, not of the military variety. phil mattingly, the white house. meanwhile, u.s. vice president kamala harris headed to a political hot spot back home. she went to the u.s. mexico border friday, visiting a migrant processing center in el paso, texas, stemming the record tide of migrants coming from central america, she hadn't gone to the border as vice president until now which opened her up to criticism from republicans, harris said she wanted to visit mexico and guatemala first to start addressing the root causes

afkari executed in iran, found guilty of an antigovernment protest but in a trial his family says was a sham, he denied the charges. audio clips of him standing up to the authorities in iran now circulate freely and his courageous stance has emboldened his supporters to keep fighting. cnn world sport don riddell has been speaking to friends to find out who was navid afkari. >> the life and soul of wrestling, the top wrestler in

iran, executed by his government in 2020. >> i knew something happened. and when i listened to one of their voice mails, my journalist friend, i just cried, you know, i couldn't control my tears. >> a former junior world champion from iran. he was involved in the campaign to try and save afkari's life. >> they were telling me, that you can be available in one hour, to have entered, and they wanted me to be there, but it was one of the most difficult moments. >> afkari had been accused of killing a security guard during a protest rally in 2018. a charge that he confessed to initially but later retracted, because he said he had been tortured. during this exchange in court, he can be heard challenging the authority of the judge in a trial that his supporters say was rigged against him .

>> his family and human rights groups in iran say that no compelling evidence was ever presented in the case against him. in such a straight society where any challenge to authority could be severely punished, it is very uncommon for such a recording to even exist. let alone be out in public. leaked by human rights activists, its very existence is evidence that afkari's death has now galvanized those who are calling for change. before he was hanged, afkari recorded an audio file in prison demanding the world take notice of his plight and political prisoners detained in iran tortured and executed.

>> a campaign group called united has using his courageous stance to highlight the oppression of other athletes and citizens by iran's governing regime and they want the international olympic committee to ban iran from the games. >> he was sending an audio file from prison. he had hope. i have the same hope. i want to do something. and this is the first step. united for navid, is trying to get the attention of the rest of the world, to not ignore what happened. people are asking you for help. >> since afkari's death, life has become very difficult for those close to him, two of his brothers are also in jail, and the family is under pressure not to speak. which is why one family member agreed only to talk with cnn if

their identity could be protected. they say that navid's mother is conflicted in her grief. >> she's so sad for losing navid. and secondly, she's so proud of navid because she knows that navid choose the right path. >> for those that navid afkari left behind, the direction of the path is now uncertain, but his faith has prompted other athletes to speak out against the government. >> they bear his name like his body, but he's a hero for millions of young athletes, and he's everywhere now. >> an execution intended to silence and intimidate may just have had the opposite effect.
