>> the problem is we don't know the effectiveness of the j&j vaccine. we need to know because we have two very effective mrna vaccines, and if j&j is not effective, it shouldn't be on the market now. also, we may need to boost people. >> which is crucial. everyone at j&j needs answers. thank you very much, dr. reiner. it was nice talking to you. now it's time for "anderson 360." john berman in for anderson tonight in surfside, florida. we begin with audio of a first responder trying to tell his dispatcher of the magnitude of what he was seeing here just moments after the tower fell. >> this is going to be a high

pri priority. we're going to need trts. we're going to need full assignment on this from everybody. this building does not look stable. a quarter of the building that's left -- we still have people standing upstairs that still need to be evacuated. >> it was more traumatic than he knew, a sense of dread, the number of people unaccounted for became known and then grew. one official today got choked up talking about a birthday card with butterflies found in the rubble. the card had blood on it. it's so wrong, he said. yet even in uthe urgency of the dwindling time to locate survivors, it's being treated with the same kind of tenderness and reverence and care that we

all remember seeing at ground zero 20 years ago. the first responders are working in 12-hour shifts. we'll be speaking with one of them shortly. up to 3 million pounds of concrete has been removed from the pile, but it is still slow going. we are focusing on two tracks, for the forensic effort to find out what caused this and those unaccounted for. since we left you last night, the death toll has climbed by one, the name not given yet. 12 now dead, 149 unaccounted for. marcus gora was 53 years old. also identified, frank kleiman,

55. his son tells us his father was born in costa rica and moved here when he was four, michael altman. senior correspondent drew griffin with the very latest on what we know tonight. >> reporter: as more lawsuits are being filed across south florida in the deadly collapse of the champlain tower south condominium, there is more evidence residents, engineers and the condo board knew their building was deteriorating. a letter e-mailed on april 9, just three months ago, warned the observable damage such as in the garage has gotten significantly worse since the original inspection. that original inspection in 2018, just three years ago, it determined failed waterproofing was causing major structural damage to the concrete

structural slab below the pool deck and entrance drive. it led to a major assessment. $15 million to repair years of damage. >> there were leaks in the garage, there were cracks on the balconies. yes, you need the money to fix it, you know? but, unfortunately, it was ignored. >> reporter: he said he received the letter in april telling how the concrete was deteriorating. the roof had gotten so much worse, so extensive roof repairs needed to be incorporated. the letter was sent to homeowners to understand their share of the assessment. anywhere from $8 n$8,000 for a one-bedroom condo, up to $125,000 for a penthouse condo.

>> it's extremely rare for a structure that's been standing for 40 years to all of a sudden collapse in this way, but i'm sure that forensically we structural engineers will figure out what happened and we'll get to the bottom of it. >> reporter: records show a surfside building official had determined major structural damage, yet told residents it appears the building is in very good shape. the records made public show no sense of urgency to launch repairs as the homeowners' association took lee years to review inspections, hire engineers and begin assessments to start work. an attorney for the condo board cautions patience. >> there are other buildings out there with engineering reports as they near their 40-year certification that reveal more drastic falling and pitting, rebar corrosion. we need to figure out what were all the factors that went into making this building fall.

>> and drew griffin joins us now. drew, there is word that a florida grand jury will soon look into this tragedy. what does that mean, exactly? is this a criminal investigation or just fact-finding at this point? >> it's more fact-finding. kathy arundel, state attorney, will look into everything about this, as she says, to potentially strengthen the laws, strengthen the codes, strengthen the safeguards to prevent this from happening again, similar to hurricane andrew that wiped out so many houses. >> it made such a big difference after. maybe the same thing could happen here. drew griffin, thank you very much for that. joining us now is al allyn kilsheimer joins us.

he was the investigator for the world trade center and the oklahoma bombing. this can be overwhelming. where do you even begin your investigation? >> the first thing you do is you take a look at what you see still standing in the air, and to the extent it's possible, you try to find structural drawings of the original design of the building, and then you begin -- at least what we do is make a little list in our head of all the things that we can think of that might have caused this kind of problem. and then we begin doing materials testing, ground investigations, structural analysis of the design that's shown on the drawings. we look at the history of the buildings, exposure to diagrams, any stuff like that. as you do all that, the list you

start with, let's say it's 20 to 30 things, based on experience gets reduced. you have some things you could say, well, that isn't what caused it. what you're looking for is a trigger, because as you all said, this building sat here for 40 years and didn't come down until now. something certainly -- so the idea is essentially you look at all these things. you will find things that were wrong in the building because every building, just like when a doctor comes to look at you, he might be looking at one thing, but -- long story short, as you go through all these analyses, you get rid of some of the things you can prove to yourself are not a cause, and then you add more things as you go along. what you're looking for is

you're looking for the trigger event. and then as you do that, you look and see, well, say we find four things that are not perfect which, like every building has that. this one thing, it still falls down with the trigger event. you go through all the different combinations. when buildings we've looked at were hit by planes or bombs or things like that, you know what the trigger event was. here you don't know what the trigger event is, and generally speaking, you can't get down to one particular cause unless you can prove that. that's what we'll be doing over a long period of time. >> sorry, allyn, there is a thunderstorm here and your sound is going in and out. i don't mean to interrupt you. you said you have as many as 30 different theories of what might have happened here. what are a few of them?

>> you know, you go through looking for triggers, you know. this is just me thinking this, not any thought -- i have nothing that tells me that any of these were even possible, but you don't know, so you have to find out. things like a bomb explosion -- things like that, a trigger kind of event. foundations moving around more than a certain amount. all those things are trigger events. sometimes buildings talk to you if you can listen to them, so what happens is it's possible that slabs in the building were deflecting for long periods of time. that means spinning downward and nobody knew anything about it or didn't understand it. all those things can eventually lead to a problem. there are other issues that

precipitate the collapse. what you want to do is try to find the trigger. >> if you can hear me, allyn, you've obviously seen the pictures in the "miami herald" from a pool contractor that showed cracks in the concrete, water on the ground there. you know about the 2018 report that was done by the engineer. does any of that raise red flags for you? >> you know, while some of those things -- i've seen things like that in lots of buildings. the bottom line is you have this particular building, and a lot of buildings, you have the building tower and then the first floor and the basement stick out further than the tower in the plan, and that's where you have planters and driveways and stuff like that. you have waterproofing on those

things. waterproofing only has a useful life and after a period of time, you have to replace it. the north building, i think, last year or the year before, replaced all the waterproofing. the issue is when water gets into a crack, all concrete cracks, it's made to crack. water gets into a crack. in the north, you worry about it freezing and thawing, because when water freezes, it expands and that makes the crack bigger. then you can get rust in the reinforcement steel. when rust gets in the reinforcement steel, at first glance it might look severe, but remember, it's an expanded material. you take a wire brush and you brush off that rust and you might find you only lost a 16th

of an inch or half-eighths of an inch of a piece of rebar. >> allyn? >> just seeing cracks in limited areas doesn't mean that caused the collapse. it -- >> it's a beginning. it will contribute, i understand. >> you're just beginning. allyn kilsheimer, i appreciate you joining us tonight talking about the investigation. you're just getting started. vast experience to bear. thank you. a mother came home just in time to save her two children's lives. this is such an amazing story of feeling something simply is not right and then acting on it. later the story emerging behind so many images it won't be forgotten. what we're learning about the woman who lives here and is unaccounted for tonight.

in all the heartache here and all the questions that won't have answers, there is this and we couldn't be happier to bring it to you. a mother and her two children are safe tonight, and they may not have been. st sara nier was home seconds before the tower fell, with her daughter hannah who was there. it was late. 12:30, 1:30 in the morning. you were doing e-mails and then you heard a sound. what happened? >> it was 12:30 and it was a little bit noisy. my son and daughter was around me. i didn't pay attention to the surro surroundings. about 12:45 she went to take a shower and my son was busy and

suddenly it was quiet. i started reading my e-mails and messages and i started to hear a knocking sound. i thought, okay, someone is probably hanging pictures on the wall. then it was more intense and i thought, someone is doing a small renovation. then suddenly around 1:10 i hear like a smash and the wall is collapsing, the wall above me. i'm like, wow, they're really doing major construction. i need to take care of this problem, but it's already 1:10 in the morning and it doesn't make sense. i ran to the security guy. i live on the ground floor, so it's first floor. it was separated between my apartment to the security guy, and i went to him and i said, do you hear these sounds? it doesn't make sense in the middle the night, early morning, people doing construction. so he said, yeah, i hear also these noises. i said, so what do you do about that? the minute i said, what do you do about it, there was a big boom and i was running to see

where the sound came from. and i saw all the garage collapse. i couldn't believe it. i thought i am in a movie. i look again and i ran back to the hallway and i saw my two kids standing next to the door of my apartment saying, don't move. it's an earthquake. i was thinking very fast. it's not construction, it's an earthquake, and while i was running, i said security guy, call police, put on the alarms so people will be aware of this. when my daughter was looking at me she said, i'm in my bathrobe. i said, i don't care, run as fast as you can. she was running with her brother toward the exit of the building. the security guy was shocked. he didn't know what to do. i said, call the police. he said, but what is wrong with this building?

i said, no, no, and i told my son let's go. we ran out of the building. we ran on cross the street. we just crossed collins. god was waiting for us to leave the building, then another big boom and we didn't see anything. it was suddenly quiet after the big boom and it was white clouds all over, and i thought i was by myself in this world. we were still running and i told my son, call the police again, call the police again. finally my son was very curious to see. i didn't tell him to watch what was going on in the back. finally he looked and he saw the building collapse. i said, it's an earthquake. we're still running and running. i couldn't breathe, i couldn't do anything, and i said, god help, god help. i didn't know what to do. we had been really running three

or four blocks away from this building, and then i said, i need to breathe. so i said, i need to knock on somebody's house to help me, to help me, i couldn't do anything anymore. so my kids said, mommy, it's really late. nobody will open the door. i said, it's an earthquake. people need to know to help us. suddenly a guy came with his big dog. i look in the window and i said, please, open up the door, i can't breathe. he said, no. >> when you heard the sounds and your mother tells you you have to go, what did you think was going on? >> in the beginning, because i was in the shower, i thought in the beginning someone was doing construction also, so i thought when i went into the bathroom, i would see in the living room planks of wood, because maybe someone was doing damage into our apartment.

i ran out and there were white particles coming at me. i was like, this is not normal. i ran out of the apartment and i'm in a robe and a towel. i'm not really going out in public like this. so, like, no one really thinks -- in the moment you're just shocked. you're like, what's going on? things are collapsing, but you don't know, is the whole building about to collapse? you don't know what's going on. >> i know this is your first time back anywhere near the building. what does it feel like to be here? >> i want to say how great america was, because it's painful and scary and i see what's really happened, and how many people -- we don't know what's up with them. we don't know. i said how lucky we were, and thank god what's happened. we were safe from this trauma, but we are still in trauma. the recovery and things that we

and probably other people are going through, you can't even measure, you can't really -- i'm speechless because i don't know what to tell you. when i entered this site over here, i didn't want to come close to the area, even. there's so much things i'm going through now. >> i know you feel that god is watching you, and i'm so glad you made it out. i'm so dpglad you listened to yr intuition. and listen to your mother. i wish you the best. >> god really helped us, and all the people helping in the communities any way they can do. i think everybody is here tries to do their best. >> thank you, both of you. be well. next the story behind one of the most indelible images of this tragedy, and the woman who lived in this apartment, and tonight is still 149 still

she is now able to share some of her story. >> reporter: this is the view that drew linda march to champlain tower south. she rented a penthouse here just three months before the condo tower collapsed. >> linda saw the pictures. she absolutely fell in love with it. it was penthouse level. it had balconies, it had a view of the water, and it was, you know, a building that had everything she wanted. so she was really, really excited about moving there. >> reporter: penthouse number 4. this is what's left of it today, one of the haunting images of the surfside building collapse. with the walls sheered off and the building ripped wide open, those bunk beds in linda's apartment are now teetering on the edge of the tenth floor. the sheets and pillowcases remarkably still intact on the bottom bunk.

for days many have wondered if children lived in that unit, but linda's friend says she rented it furnished and lived there alone. when cindy saw the building collapse, she quickly compared it to the address on the envelope linda had recently sent her. >> i matched it and our hearts sunk. we didn't know what to do. >> reporter: cindy called her friend. no answer. then she sent this text, asking her friend to make contact. it's your address, and i'm worried now. >> we tried to look up diagrams and floor plans. what if she was in this room or another room? there is a possibility if she slept on the couch in the living room. we were all praying, just maybe. the luck of god that she is in another room, that she somehow is somewhere else and not where

the shaved-off part of the building is. >> reporter: cindy hinton has known linda march for nearly 40 years and refuses to give up hope. do you think she has the strength to survive something like this? >> you know, one thing we know about linda is she's strong. you know, even though she is 104 pounds and she's petite, she's one of the strongest people i know. and i know she can feel our vibe that we're pulling for her. come on, linda. we know you can pull through this. we keep the hope. >> linda's friends describe her as intelligent, compassionate and the most generous person they know, always active and full of life, riding around surfside on this bright pink bicycle. >> she got this new pink bike and we were laughing because it was just totally linda. >> reporter: so many questions

amid the prayers they'll one day hear linda march laugh again. >> she had a very infectious laugh. when you heard linda laughing, you couldn't help but laugh and laugh with her. there was so much goodness in her heart. >> an infectious laugh. randy kaye joins us now. what about linda's family, randi? have they been asked to give dna like so many other families are? >> it's so difficult. her friends didn't want to come down for a dna identification, but it turns out she has no immediate family. her sister passed away from cancer, her parents are gone. her friends can't give dna, she has an ex-husband, they're divorced. he can't give dna, but i learned tonight that they have located an elderly uncle who spend much of his time in rome. in fact, linda saw him not long

ago. he has been in touch and he has given a dna sample. they're hoping it doesn't come to that, but they now have a dna sample to match to linda march, john. >> what people want is closure. randi, thank you so much. there are eight search and rescue units from other states. eddie al lacon, thank you for being here. you go to work tonight. this is before your shift. you're go to go to work for the entire night, so thank you for what you're doing. what is the hardest part about this right now? >> the hardest part, you know, the first day we got here seeing just how devastating everything was. we're all trained to kind of maintain our composure and do our jobs the way we're supposed to -- i'm sorry, i've been working on very little sleep right now and it's hard not to

get emotional about this stuff. it's hard not to put yourself in that situation. not to put yourself in the position these families are in. we started thinking about it in that way, what would i do, how hard are we going to work to save our family members if something like this were to happen? >> you're there for the families. >> yes, sir. >> what are you finding, mostly? >> it's just so hard -- unless you're there, you don't understand how difficult this is. i thank god for the support of my teammates, all the rescue specialists that are doing an amazing job. i've never seen so many people come together. sorry. z >> i get it. it's physically exhausting, it's emotionally exhausting. you want to find people. that's what you do. you're a rescue coordinator, and

that's not what's happening here. is it just chunks of cement at this point? >> listen, i can tell you that none of us have lost hope, because i know miracles happen and i believe in a higher power and i believe that if somebody is going to find them, we're going to make it happen and working together as best we can. we train for this kind of stuff all the time. you just pray you never have to use it. but i can tell you, like i said, we've got teams from all over the country, all over the world, working with us and being supportive and looking out for each other. >> walk me through what your shift is like. when you go on at midnight tonight, what will you be doing? >> we'll start with a briefing to hear about what happened in the shift before. then they'll put us in a staging area where they'll give us our assignment. then we'll march up to that pile

and start hammering away and cutting away in hopes that we can find somebody and hopefully -- we're always praying for somebody to be alive, but at the very least, it gives some closure to the families waiting to hear from their loved ones. >> have you had moments over the last several days where you thought you might get that miracle? >> all the time. we don't stop thinking that. that's what we do. >> any signs, any physical signs, though? >> i personally haven't seen any, but it doesn't mean that it can't happen. >> how long do you think this will go on at this point? >> it's hard to say. it's annie ormaechen r -- it's an enormous amount of work. the pile is endless. we're working night and day and we're just barely scratching the

surface but i know we're making progress. >> you said you were trained for this. when you walked on there for the first time, did anything prepare you for that? >> when i say we're trained, i mean the specialty things, working with the tools, trying to move the debris. but nothing could ever prepare you for what we witnessed when we first got here. there's just no way to describe it. >> if you could say something to the families who were waiting tonight, what do you want them to know? >> i just want them to know that we're doing everything we can. everything in our power, every single one of us who are here are doing everything in our power to bring somebody out alive or, like i said, just to bring some type of closure and to let them know we're doing everything we can for them. that's all. >> listen, my friend, if they were here, i know they would

thank you, and i know they would say they appreciate what you're doing. please take care of yourself. i know you're working as hard as you possibly can, but take care of yourself in this also. it's not easy. >> thank you. >> please give our best to everyone you're working with. >> i will. thank you very much. >> thank you, sir. we're going to have more on the condo collapse coming up. first some other major events making headlines today. a sharp spike in a virulent strain of the coronavirus here in the u.s. dr. sanjay gupta on the delta variant and the state of vaccinations in this country when "360" continues.

s of. while we're here in surfside, we want to take a moment to talk about the other headlines. the cdc reported the variant now accounts for 26% of cases in the united states. variant concerns are now behind l.a. county's decision to recommend masking inside when in public areas even for those vaccinated. worldwide bangkok is reimposing restrictions. also cities in australia are in the middle of a lockdown due to a rise in this strain and a low vaccination rate. dr. sanjay gupta joins me now. sanjay, terrific to see you. i want you to know everyone down here is still talking about how

wonderful you were with them when you were here in surfside. i want to talk about the delta variant. 26% of covid cases now in the u.s. what does that mean? put it in perspective. >> we're starting to get an idea of the trajectory of growth. this is not going to surprise you because you know this is a more transmissible variant. we can show you sort of the progress. it was a small percentage in the beginning. we were sort of keeping an eye on it. over time the percentages have grown. and now, 26%, as you say, that was roughly as of a week ago. some models say it could be as high as 40%, john. in l.a. you were mentioning close to 50%. at the same time the alpha, which was the u.k. variant we were talking about that used to be the dominant strain here, is no longer the dominant strain here. this is sort of expected because this is a more transmissible strain, this delta, it's sort of crowding out, if you will, the other strains.

>> the "wall street journal" is reporting that some people in israel who were vaccinated with the pfizer vaccine, that they have become infected with the delta variant, infected. what exactly does that mean and is that alarming to you? >> not necessarily. so these are these breakthrough infections which basically means you've been vaccinated, you got an infection, anyway. a lot of times they're found just on routine screening. people get screened for all sorts of different reasons. they feel fine, they have no symptoms, they get tested and they're surprised to find out it comes back positive. that is a breakthrough infection. john, as we've talked about for so long, the real efficacy, effectiveness of these vaccines is in terms of preventing you from getting sick, needing to go to the hospital or dying. i think we have to keep a close eye on israel, and what's going to be really important is they're around 60% vaccination, so a bit higher than we are in the united states. do you start to see a corresponding increase of

hospitalizations or evidence of severe illness? we're not really seeing that as of yet, and i hope that we don't and there is a good chance we won't because of what we know about the effectiveness of the vaccines. this is the good news that has held up in terms of the effectiveness of the vaccines. we have the graphic. basically it shows that if you're looking at these vaccines, whether it's alpha, whether it's the delta we're talking about, you're still getting really good protection against severe illness. just keep in mind the flu vaccine in any given year, 40%, 50%, maybe 60% effective. look at the numbers there. much better. >> much better. just to be clear, infected doesn't mean sick or hospitalized. right now that's an important distinction. l.a. county recommending, not requiring, but recommending that people wear a mask inside again. they want to better understand how and to who the delta variant is spreading, they say. what do you make of this

decision? >> i think there is the precautionary principle that's being applied here. they don't want to get caught behind here, not suggesting they will, but the cdc has not yet said, change their recommendations. they still say if you're vaccinated, you don't need to wear a mask indoors. i think there's a couple things to keep in mind. you might be walking into a situation where you simply don't know if anyone around you is vaccinated or unvaccinated. if you are vaccinated, you should still feel comfortable that you are well protected. that's the good news. if you start to get increasingly tr transmissible variants, there is that chance. we're not arguing the efficacy of the vaccines. we want to put the fire out of this pandemic, and the way we do

that is to really contain it strongly. that means for a period of time, give this virus nowhere to go. give it no suitable options. even a vaccinated person who may be the product of a breakthrough infection, stop that from happening. unvaccinated people get vaccinated and we can put the fire out. that's what they're saying. >> getting vaccinated is still the best thing people can do. sanjay, super helpful. thank you very much. ahead, more on the condo collapse here in florida. plus rising concern about possible violence whenever the so-called results from arizona's so-called audit of last year's election results are released. and some significant news as well about the next election. all of that coming up. your heart isn't just yours. protect it with bayer aspirin. be sure to talk to your doctor before you begin an aspirin regimen.

more on the condo collapse in surfside, florida in a moment. first some things on our radar. maricopa county, arizona says in their next election they won't use any voting machines thavt have been in the hands of contractors running that audit in maricopa county. they said the machines can pose a risk to free and fair elections after being subjected to inspection by a private firm called cyber ninjas. as for the voting count itself, no risk for wrong results, if you can call it that. however, there is a risk for possible violence whenever totals are released. for that cnn's kim lah who has been following this from the beginning. >> in the past america had such

a good solution for dealing with such traitors. execution. >> reporter: you are listening to a threat by defenders. maricopa county supervisor and republican bill gates tweeted his response to this video calling it hateful, dangerous, aberrant. this time of rhetoric is why at the maricopa county elections department in downtown phoenix, democracy here braces for what may be coming. the months-long so-called arizona audit is in its final hours on this coliseum floor. a partisan-driven exercise reviewing maricopa county's 2020 ballots despite two previous audits that showed no evidence of widespread voter fraud. the republican state senate promises it will release what it calls a report in the coming weeks as rhetoric grows more violent. it is why the elections building is being fenced by two layers. we've seen attempted breaches

before. last november as we watched election workers counting the vote -- >> there has been a security situation. >> reporter: -- the maricopa county elections department was suddenly surrounded. >> this security situation? >> reporter: a large mob was shouting to break into the elections center. >> you can see a long line of law enforcement, the sheriff's department and a very large crowd. >> reporter: a few sheriff's deputies were all that protected election workers as more scrambled to protect the vote. maricopa county sheriff paul penzone. when you see that fence go up, what do you think? >> symbolically i think it's a slap in the face of everything we have been as a nation. that's what we see in nations where there is civil unrest, no democracy and no respect for each other. now it's a necessity. that's a sad statement. >> reporter: nearly six months after the insurrection at the u.s. capitol, penzone says the

release of a report gives extremists another rallying event. arizona has been fueled by extreme anger. >> they want to know when the right time is so they can have that combustible moment. they want to know where it's most impactful. >> reporter: are you getting a feeling of timing of when this should happen? >> no, and we should so we can best prepare how to deal with potential escalation of violence. by not doing so, you are being reckless on behalf of the community. >> reporter: penzone says they have shared zero information on what to expect in the audit report. he's left largely guessing, planning for the unexpected with federal agencies. >> not an audit is what's happening there. it's performance art. it is largely a clown show. >> reporter: even if this bamboo hunting uv light using lazy

susan spinning exercise appears ludicrous, says former department of security matt ma masterson, the experienced take this as truth. >> january 6 is the ultimate symbol of the rise of extremism, domestic extremism here in the united states, right, so it is -- if that can happen at the u.s. capitol on the day that election results are scheduled to be certified, we all need to be aware that can happen anywhere and take the necessary precautions for sure. >> reporter: while arizona awaits the release of this so-called report, the rhetoric is not calming down. after some significant outrage, that oan personality tried to explain the threat but he did not apologize. kyung lah, cnn, los angeles. >> our thanks to kyung for that

here in surfside, there's been a lot of attention to the north tower, an identical building near the one that collapsed and questions about whether the north tower is now safe. cnn's brian todd was allowed inside to have a detailed look around, and brian joins me now. brian, what did you see? >> john, i saw an area where maintenance and upkeep is kind of an obsession to people in the tower with the president and the vice president. we talked to both of them today. they showed us the garage, the roof and the pool deck. we've seen the garage like sunny aisles condominium and other places. at the garage in the north tower, it was pristine. no cracks, no water, no exposed

rebar. there was a sump pump down there that was brand new. you could have eaten a meal off the floor of this garage at this place. the roof, everything was sealed. and from the roof, they showed us the balconies. the balconies are an interesting story, because you saw the miami-dade mayor said they had to shut down some balconies in another building here. well, they told us that three years ago at the behest of the condo association president, they ripped off the tiles of the floors on all the balconies. he saw it. and he said, this is too heavy and it's building too much moisture and damage on the floors of these balconies, and it's going to cause problems. and he, three years ago, saw this problem. he was very prescient. he said, you're going to have to incur these costs. each unit had to pay a little over $10,000 for it. but they got it done. those balconies are completely fortified and they look perfect. >> do people in that tower feel confident about their safety? >> they do now.

some left but experts came through after this collapse and gave it a really high bill of health. that caused the return of the residents there. >> to your eye, they look even better than those other buildings. brian todd, thank you for that report. the news continues, so let's head over to chris for "cuomo prime time." >> thanks, john. we learned tonight another body was found in the rubble. that means 12 have been confirmed dead. i suggest to you that that is the only number that we can be sure of in terms of how many might be lost. tonight we're dgoing to test th idea of how many are missing. is it 150? who decided that and how? here's what we do know. first responders have now moved approximately 3 million pounds of
