story of the first responders desperately trying to find life at that condo in surfside, florida. right now, let's hand it off to "a.c. 360." good evening. at the dimming of another rough day here in surfside, we are waiting for late word from officials on the state of search, recovery, and rescue operations. we expect a press conference any minute now. we'll bring that you live. already, the news has been difficult. today we saw the number unaccounted for or potentially lost or trapped in the rubble of champlain towerses, which is right over there, that number rose sharply. the news only adding urgency for rescue teams already who are working nonstop and have been throughout the night. it is, however, the most delicate job imaginable. under the toughest conceivable conditions, where even one wrong move could cost lives or maybe even saving lives, making it harder to save lives than it already is. >> these first responders are

going in through tunnels. they're working from the top. they're working from the bottom. it has to be done very, very carefully. debris is falling on them, as they do their work. we have structural engineers on site to assure that they will not be injured. but they -- they are proceeding because they are so motivated. >> as she said, debris is falling on them as they try to rescue others, as they search for those who are trapped somewhere in that rubble. the weather complicating efforts, rainy weather, as you heard. they've also had to contend with fires breaking out on site. you can see in the shot on the side of me, on the left side of me, i believe it is, the -- just the smoke coming off the rubble of this building and it permeates this whole area, as they search what could be as many as 159 people not yet accounted for. they can't be sure of exactly

who's in the building at that moment. they're trying to trace as many vehicles that are in the garage as possible. thinking that will give them an indication of, well, if somebody's car is in the garage, there was a good chance they were in the building. for most, that means family members, friends, and neighbors have been gathering at a local community center, waiting for word, holding out whatever hope they can muster, and finding it in surprisingly good supply. >> there's absolutely survivors in here. there's no question there are survivors in here. i hope it's my family and i hope it's everybody. >> well, that's mike silver, who rushed here from new york, whose uncle and four other family members are among the missing. so far, only four bodies have been recovered. four people have been recovered dead. three have been so far identified. waiting families tell cnn, they're having dna samples taken in case they need to identify what could be many, many more. they are also, of course, waiting and looking for answers.

>> building falls down in a third-world country where they don't have, you know, building codes and stuff. but with all the strict building codes in this country, that building shouldn't collapse like that. >> his parents are missing in the rubble right now. today, florida's governor promised a speedy investigation into how this could happen. president biden pledged federal assistance. and at an emergency meeting today, town officials said they're hiring an outside engineering a firm to evaluate the structural integrity of other area beachfront towers. tonight, though, the search takes priority. with me now is vatina obias. her aunt and uncle live on the building's tenth floor. thank you for being with us. how you holding up? >> i'm trying to be strong, because my aunt was a very strong woman. >> she was like a mother to you. >> yes, she was like a mother to me. she was the mat riarch of the family. >> you flew here in the

afternoon. didn't know -- >> in the early morning. >> when did you realize that they were in this building? >> when i actually grabbed my things from the baggage claim, i found out that from my sister -- she's a nurse here, a front liner -- that my aunt's apartment condo collapsed. so when she asked me to -- as soon as i heard this, my sisters were still asleep, i grabbed an uber and came here. and -- >> you just came down to the site? >> yes, i came to the site. and as soon as i saw this, i fell apart pretty much. because when i saw this, i knew that they were gone. it's hard for me to take a look at it right now. >> and it's one thing to -- you know, one sees things on television and when you're here and the smoke and the reality of it, it's overwhelming. >> yes, it is actually -- when something like this you see on television, you're pretty much

de detached, but when it becomes a part of you, your family, it hits you really hard. >> you've been to the center where family and loved ones can go. what is that like? i know they give update evers four hours, but there's not a lot to update, i imagine >> when i came there yesterday, they were very much quickly very organized. i think that the red cross was there and they took a lot of information. they were trying to gather as much data from everybody that were missing. we didn't have a lot of information as to how many people were missing at the time. so they asked me where my aunt's apartment was located. i said, it's 1001, and they were quiet. so they checked the list of the people who were in the hospital and people who were in the survivors -- people whose whereabouts they can account for. >> yes, yes. and i knew when i saw that it wasn't there and i saw this, i just had a very strong feeling that they're gone. yeah. yes. >> are you -- are you -- do you hold on to hope?

>> i'm actually very much a pragmatist. at the same time, also -- >> you want to be prepared for anything. >> yes, yes. i think hope is a very valuable thing when people are going through crises to hold on to. so i'm holding on to a slifrverf hope, because i know someone buried still alive. and if it's not my aunt or uncle, i hope it's somebody's father, somebody's son. >> every rescue person we've talked to said, people can survive for very long periods of time in buildings you can't imagine they would survive in. >> that's what i've heard. so i'm hoping there are many survivors. i hope that they get to them >> what do you want people to know about your aunt and uncle? >> i want them to know that my aunt and uncle were -- my uncle was a united nations legal

counsel, a retired one, and my aunt was a -- she was a international military fund budget officer, official. so as a matter of fact, my uncle, i don't know if you know the former president of chile, is his niece. >> oh, wow. >> this is a very international building. >> yes. >> i know there are people from paraguay who lived here who have -- a lot of people in paraguay are watching right now, very concerned about this. people all over the world are watching very closely. >> there are a lot of people actually that are from international, expecting people tomorrow. and chile. >> does it help in some ways to be able to be here and see that there are so many search and rescue people here, to see that there's a lot of folk on people trying to do everything possible. >> yeah, sometimes you see people, you want them out and

people are getting frustrated, but these people are experts they've been through a lot of -- they've been through a lot of these kinds of rescue. we're just hoping that we're still in the rescue portion, not the recovery. and that's what we're hoping right now. >> bettina, thank you so much. stay strong. thank you very much. we are expecting a press conference very shortly. it is a very active situation here. there are obviously medical search and rescue teams coming and going, police and fire units, structural engineers, city officials and again, there is this sort of otherworldly feel with this smoke, as you can see behind me. sanjay gupta is with us. you've been here throughout the day. you were here for another story yesterday and you came down here. talk about what you've seen throw the day. >> well, you know, it's been an on again/off again sort of search and rescue. you know, there's been weather, you can see right now, this is

more activity, i think, than we've seen in a few hours. so for a period of time, when all the rain was there, it really did hamper their efforts. >> it's such a desire to find somebody and get to them as quickly as possible, and the very real dangers of the structure collapsing on them. of them removing debris can shift the structural balance. >> we're seeing a portion of a building, obviously, that is still standing, that has another portion that's gone. so we're very worried about that. and also, you can smell the air here. all the fumes. these rescue workers are in 15-minute shifts because they want to reduce the exposure to these fumes. >> which is something a lot of folks learned after 9/11. this smoke is not good. >> it's not good. and obviously, this sort of duration, hopefully, won't be as bag p big a problem as what we saw after 9/11 when people were on

the pile for days and weeks on end. but 40-year-old building, you h have asbestos in there, probably, you have chemicals, and all of this stuff that's burning and that's what we're smelling. >> and there's also a concern about the water that was pumped into that building, some of the video we saw yesterday that was released by miami-dade fire and rescue, they're working in water, that's water that has been pumped in from put out fires in the build and such, that actually adds to the weight of the structure, and that causes even more concern. >> it's a big concern. and even packing down the pile more with that weight of the water makes it really challenging. i know you'll speak to some of these search and rescue guys later on, but the point you're making, we are doing this obviously at risk to ourselves, it's always a risk/benefit ratio. at which point does the inflection sort of flip, right? in the sense that, as you well know, anderson, most successful rescues occur within the first 24 hours.

you mentioned 9/11. the last successful rescue on 9/11 was 27 hours. >> you know, we saw in haiti, i mean, there was -- i remember being on site, it was at least seven days after. >> and there's always those stories. that's the hope versus honesty kind of thing. but balancing it with the risk that these search and rescue guys are putting themselves into, as well. as you mentioned, debris falling on them. when you start to learn about engineering, i hadn't realized that there's different kinds of collapses. there's pancake collapse, which is what this is, but apparently, for some who have been really examining the video of the collapse, there's a whole variety of -- there's a v-shaped collapse, there's different kinds of collapses, lean-to, all of which make it possible that for somebody to have a space where they can stay safe. i understand the press

conference is just getting unde underway. >> they are passionate about this. they are dedicated to finding people in the rubble. so we stand with them. and we're going to give them all the support they need to get the job done. we've been joined by teams from all over the state and we have the best people for the job and we have the right people for the job. the people who are here are highly skilled and trained. they are the ones that go all over the world, wherever there's a trouble spot needing this kind of rescue. and they are using the skills and the tools to get this job done and as well, they continue to believe that there are people that they can reach, getting through the crevices, pushing through walls, removing debris, safely, with the advice of our structural engineers and so we

stand with them to get this job done. so, to the families who are waiting for news of their loved ones, we are giving them twice-daily briefings, with details of exactly how the search is being conducted. we are providing for their living and hotels and meals. they're with chaplains. many are celebrating the jewish sabbath right now at sundown. and we know that they are f fee feeling very, very concerned, of course, and anxious, and wondering, and we are telling them that we are here working, praying, and really still hopeful that we will find more of their loved ones. unfortunately, the numbers are the same that they were this morning. we have not found anybody else

in today's search, but through the night, we will continue and god willing, there will be some good news later tonight or in the morning and we will be back. we have created a village here a village of media, people all across the world watching, waiting, caring, donating, the world is watching and the world is caring what happens right here in surfside in miami-dade county. we are so grateful for the support of our cities, of our state, of our federal government. fema has come to the rescue. we're going to have more resources to pay for this expensive search and rescue and to give us access to more teams for the rescue later, for the clearance of the rubble and for the assistance for the families, as they put their lives back

together. so we're here, we'll continue, and please stand by us. stand by us, as we stand by the family. thank you. >> that was the mayor of miami-dade county here with dr. sanjay gupta. you can hear metal being cut, so there are things happening. but as we were talking about, and as you've been talking about throughout the day, it's kind of on/off in terms of how active they can be. even the question of whether they start to remove debris at this stage. >> i think that's the thing, is that there's been all sorts of different reasons for it, in emergency terms of the weather and other things. but obviously, the mission is still search and rescue. that is what it's been called. but obviously, we're at 41 hours now at this point. so i think that's part of the reason you've seen the activity sort of start and top from time

to time. this is probably the most activity i've seen in several hours right now. so i know something in particular has happened as we're looking at the images. i know they're throwing more water on to the fires and things like that. this is the most i've seen. >> and so many questions still remain about exactly what it was that caused this. a lot of different theories. we'll go into that and have more on rescues and the search efforts taking place when we come back. what the moment looked and felt like for survivors, some of whom were just down the hall from some parts of the building that are no longer there. plus, we'll be joined by a trauma surgeon who had been working with rescue crews about the complications of being on site so close and getting into that rubble. we'll be right back. in business, growth isn't just about getting bigger, it's about getting stronger. by turning workforce data into insights that help you make informed decisions about building a team that works as a team. and by using our ai technology

building went down. people who lived next door, people who live in the same towers, just not too far from the tower that went down. we've compiled some of what we have heard throughout the day from a number of people. let's listen in. >> it was like a really loud clap of thunder. >> it kind of felt like a jet took off above the building. >> the chandeliers and pendant lights just swaying completely. and that was not normal. >> at least my husband and i woke up to that. to him grabbing me and saying, what is that. and the whole bedroom was just shaking so violently that honestly, i was prepared for the building to come down, because it was not something stable. there was nothing going on that seemed normal about it. >> really, until we opened the door, we didn't know anything happened to the building. the unit was in tact. i looked to the left and the apartment to our left was half sheared off. looked forward, which is where the evaluate shaft is, and it was just a hole. so 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. >> i hear this large, like rumpling noise out of nowhere and i actually just see like white clouds of just dust coming out. so i told my mom and sister, we were at the park outside. i told them to start running. we just ran and all we could see was white dust. >> 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 and we realized we had to get out of there, because if we stayed down there, we could drown. knowing what it looked like outside my door, i thought that at any minute, we could be that

same pile of rubble. >> i just don't know why we're here and the rest of the people aren't. having going 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 thing. i could have walked into the living room and checking on them and found that rubble. and it just -- i don't think i've processed it. it looks like i'm, in that moment, but i don't think i've really processed what happened. >> some of the voices of those who survived. we're here with dr. sanjay gupta. also dr. howard lieberman, who is part of the team of miami-dade rescue. it's extraordinary, what you and the men and women have been doing in search and rescue. explain what it's like working on this site. >> you know, the pictures basically say -- you know, sum it all up. it's a pretty devastating site. you know, the good thing is, though, we're working with a group of men and women that are absolutely extraordinary. every search and rescue from miami-dade fire rescue, they're

amazing people. it's a pleasure to work with them. >> your job is, if you find somebody with injuries, you want to have people on scene who can immediately treat. >> so my job is sort of multi-factorial. my primary responsibility is to make sure that guys that are up on that pile and searching stay safe. if they get injured, we take care of them. and that's what we're primarily there for. obviously, as a surgeon, as a trauma surgeon, and being with the urban search and rescue division for a couple of years now, we do and are capable of doing other things as well. if we find patients, we'll tree t treat them. if there's a limb that's caught or mangled, we can amputate that on the scene. we can provide any kind of care that we need to provide to stabilize them, so they get transferred to the hospital. >> it's -- it's incredibly difficult work. how risky this site?

>> it's very risky work. one minute it's sunny, the next minute it's raining, it's wet, slippery, clear everyone off the pile. >> so when it rains, work stops. >> yeah, because of the lightning, because you can't really see anything. things get really slippery up there. it's not worth risking everyone's life there to -- it's better to take a pause, keep everyone safe and, you know, able to keep the search going. as soon as the work stops, we're right back on top of it. but there's a lot of hazards there. but these guys are professionals. this is what they do. >> i'm curious, because there's disasters that this team has rescued all over the world. >> absolutely. and and you know, we were talking about this earlier. how different is this? i think it's a little bit different, because it's literally in our backyard. i think everybody is one or two degrees of knowing somebody who

lived in that building. >> you live not far from here. >> i live a block or two from here. my colleague from medical school, he's missing a cousin and that cousin's wife, who was pregnant, and their 1-year-old baby. so, yeah, it touches close to home. and i think you'll find that there's a lot of people like myself who you have that one or two degrees of separation from someone. everyone's getting text messages. like, hey, have you seen so-and-so? it's miami, it's our home. you know, it's a relatively small community. >> you're also going through the rubble of people's homes and seeing possessions and things. that's one of the things that has always struck me on sites heroic this when you come across the reality. >> absolutely. you think about rubble and metal and twisted steel, but we're seeing stuffed animals, teddy bears, box of diapers, you know, a child's bunk bed and finding a

lot of pictures, family pictures. and it's a little bit more emotional than going someone, where you know there's no one -- especially for a hurricane, where they had enough evacuation time and they got out, but this you know happened in the middle of the night. and for the first time, i just saw the video, and it's pretty oppressive. >> have you -- i know there's 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. >> yeah, there is -- 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. >> you know, this is a tough question to ask, but you know,

you want to be hopeful. we're 41 hours, 42 hours. how do you sort of balance this? the hope versus the honesty, you know? >> it's kind of been my nature, my background as a trauma surgeon. you just never give up hope. you always keep pushing ing youf and you keep going. these guys, you know, that's their mind-set also. we're going to keep going, keep going, keep going until, like i said, every stone is turned over and all of the rubble is removed. and that's how we do it. you know, they're used to it. i'm sort of used to it. both from the trauma surgeon end of it and being with the urban search and rescue department for a few years now. and you know, we motivate each other, and it's like a brotherhood, sisterhood. we're all sort of one big family here and lean on each other and support each other and we don't back down. some of those guys, you may have heard it before, you kind of have to pull them off, because they'll just kip going. >> when you're working -- >> i mean, we're looking at images right now of people climbing over a pile of what we

would call rubble. how do you -- what do you -- where do you begin? >> so, you know, so what they're doing here, in this particular footage, they're obviously searching by hand. that's why they have the buckets. they're taking brick by brick, stone by stone, debris by debris, into a bucket and taking it off the pile, looking for voids, looking to see -- they'll bring cameras in. sometimes they'll have the dogs walk on the pile first. >> and i assume it's got to be done kind of by hand, at this stage, because you don't want a backhoe going to an area where there may be somebody. >> right. so for really obviously, large, heavy structures, you're not going to be able to move them, so then you get the heavy equipment to move it, and then once that's de-layered, you can do the hand by hand, piece by piece, doing the different devices, infrared, heat-sensitive equipment. >> do you divide it up in grids? >> yeah, yeah. there's a whole search pattern divided in grids. and you know, it's numbered, and

they just basically do a grid search. and once that grid is searched and they know there's nothing there, then that's it, and they move on to the next one. it's very thorough. >> you know, i see you have the mask on and we were just commenting, you can really smell the acrid sort of heavy metal smell in the air. how dangerous is that, do you think, and also for the other residents that live around here? >> obviously, the longer you're exposed to it, the danger increases. we have a hazmat team that's here. we do decontamination wherever we leave the pile or the scene. we get our boot decontaminated. we have radiation detectors and stuff like that. so our health is being monitored. the air quality is being importanted. we're all supposed to wear ppes. this goes back before the time of covid. we're all gowned up, gloved up here. here it's masks, eye protection, ear protection. do whatever we can to keep

ourselves safe so we can do the job we have to do. >> you've got to be exhausted. >> uh, yeah. i won't lie. i'm used to it. working at ryder trauma senior is, you don't stop. and i've been with these guys for a couple of years now. i'm kind of used to it, but you can feel it. if i stop moving at any time, i'll probably pass out. >> and i think for families who are watching and loved ones who are watching and all around the world, it's got to be some modicum of hope that just seeing how hard y'all are working and how seriously y'all are taking this and how personally you're all taking this. >> we're taking it very personally. we're all from the miami area. this is like home. people know people who have loved ones who they haven't heard from. so it's very personal and that's what keeps us going. and it's just in everyone's nature. whether you're a surgeon or a search and rescue, you have that personality where you just don't quit. you don't give up. and you just keep going.

>> well, we're glad you do. thank you so much. >> thank you. >> coming up, as workers continue the exhausting work to try to find survivors here, the latest in the investigation into why this building may have pancaked into the ground. and an update on the teenager rescued from the rubble that we told you about last night. what happened to his mom, ahead. y innovations. crash-tested so many cars we've stopped counting. and built our most punishing test facility yet, in our effort to build the world's safest cars. we've created crumple zones and autonomous braking. active lane keeping assist and blind spot assist. we've introduced airbags, side curtain airbags, and now the first-ever rear-mounted front-impact airbags. all in the hope that you never need any of it.

as we've been reporting, the known death toll tonight still stands at four. one of those killed, sadly, is the mother of a teenager who was rescued in the immediate aftermath of the collapse. last night, i talked to a man named nicholas balboa who was out walking his dog. he went around to the back of the building after it collapsed, he said he heard someone screaming and helped lead first responders to where the boy was originally rescued. 15-year-old noah handler was under a mattress and a bed frame and you see him being brought out. here's what nicholas balboa told me last night. >> he told me it was him and his mother in the apartment. and i could see him, but i couldn't see his mother or hear her. and at this time, from what i've gathered from the crews and stuff like that, they still haven't been able to find her yet. >> so he didn't know where his mother was or how she was?

>> no today, family members confirm that jonah's mother, it is a stacy fang did not survive. as to why the condominium collapsed, the explanations right now obviously elusive. drew griffin joins us right now with what we know and what we don't know. drew, what are investigators looking at right now, talking about to try to figure out what happened? >> the only thing they really have right now, anderson, is that horrific surveillance camera video, which shows the moments when that building collapsed. they don't have access to the site, obviously. they don't have access to the materials or the ground underneath it to determine what would happen. and in talking to engineers and forensic experts all day long, can i tell you that anybody who tells you how or why or what happened to this building, it's just pure speculation at this point. what will be key and i'm sure investigators are moving on is a series of infectiouses that this

building was just undergoing. the building is 40 years old. by florida law, it was required to be recertified and it was going through that process, which means for the last several months, major inspections were taking place on this building so it could reply for that recertification. those records we've been trying to reach, we've been talking with town officials, they apparently do not have them or have not made them public, but i think, anderson, those will be key in determining whether they at least tart to see if there were any problems with this building. >> we know 40-year-old building, do we know much about the history of it? >> you know, by all accounts, from what we can see from the records that we have, there weren't many big problems with it. there was a lawsuit in 2015. there was an exterior crack, which caused leaking into a unit, but the damages there were only added up to about $15,000. there was a study done by a

florida professor looking at the sinkage of the building back in the 90s. it sunk about half an inch over a six-year study in which they studied this. but again, the professor is saying that alone would not have caused this problem. and from what we gather, one town official, one building official was actually on the roof of that building, looking at the roof repairs that were going -- taking place just 14 hours, anderson, before this collapse took place. jim mcginnis. and he says, look, it was a professional roofing job. everything was permitted, everything was in order. so there wasn't any clear indication of anything going on that we can see at this point, with this building. other than it was 40 years old, going through recertification, and it's a building built on sand, on the ocean. >> yeah. any sense of the timeline? i mean, obviously, everyone wants answers quickly and obviously the focus for

everybody right now is the search and rescue. what's the timeline look like for sort of understanding more of what actually went on? >> you know, to really understand what took place, we're told it's going to be months, not weeks. and unless you have a smoking gun kind of incident like terrorism or somebody smashed into one of the pillars, when you have to put together what happened, it's much like a plane crash. one small failure leads to another failure leads to another failure, so you have this string of things that take place. unraveling that often takes months. anderson? >> yeah. drew, appreciate it. thank you. as we reported at the top of the program, town officials here are hiring an engineering firm to help evaluate the integrity of other buildings in the area. with me now, kobe carp and structural engineer can be kit

niamoto, who has engineering experience around the world. kobe, thanks for being with us. obviously, there's more that we don't know than we know right now. i know you've been looking at that video of the fall a lot. what can you tell from that? >> i think that just like the gentlemen said before, it's a lot of speculation. but really, you can see in the video that the interesting thing is that the southwest l-shaped building stood. this building was built in 1981. i was in high school, i was 18 years old. this building is not old. we are working similar buildings up the and down the straight here that were built in the 1920s, '30s, '40s and '50s. >> the building right next to it, that looks to me like a 1920s, '30s building, art deco building that has been rehabbed. >> you're absolutely correct. that building was renovated and all of our buildings get renovated. that's the issue right now. this is an event that we have

never had before. you can look at it, you can speculate how it happened, but at the end of the day, it will take us months. >> it will takes months. how do you even begin to do that? >> engineering is the way to go. and the way these buildings were built which is all the same ways. concrete piles. concrete reinforcement around the staircases and elevators, which is the spine of the building, and you can see how the building pancaked. so most people believe that there was a failure between the horizontal and the vertical. but that has to be looked at, that has to be junlgd, that has to be agreed upon. at the end of the day, the reason that the northeast corner is down and the southwest corner is still up, that's a mystery. you can see the vertical shaft holding it up, that's the spine. >> you call the vertical shaft the spine? >> most of the buildings here in

florida are built in a similar matter, where the emergency staircases act as our sheer walls, that's what holds us up, our spines. and horizontal slabs is what pulls it in. >> i want to bring in kit in. you and i spoke last night, and it was so fascinating, your description of what you saw in that video. i'm wondering now, 24 hours later, what comes -- what's on your mind in terms of what you want to do, what you feel like we know more about. >> i think it's a classic collapse. if the column fell, everything comes down with it, right? so the question is why the column failed. and we talked about yesterday, a possible corrosion of the metal inside the column or a possible settlement or sinking of the ground in certain areas, at a

different rate from others. and more potentially, just lacking to the column. that's highly unlikely, but those things happen. but you have to think about the culmination of it. because the building actually is hard to collapse. there's a lot of redundancies in the building system. that's why you don't see the collapse like this. it's hard to collapse, actually. so even the area, where we live in california, that the probable collapse of a building is 1% over a 50-year time. and the maximum, maximum earthquake. it's really hard to collapse .

so maybe a whole different reasons. so maybe i think eventually, the engineers can figure it out. but you can definitely know that it's down to bottom. >> kit pointed out, it's the side facing the ocean. salt corrodes metal. and we see a building, it's the rebar inside the concrete. and the salt can get to that and corrode, right? >> yes, it does. and what we do is we come back ochbt caps and take care of that. that's part of the 40-year certification. >> to do that, do you have to cut away all the concrete? how do you get to a rebar that's in the middle of concrete? >> that's very good. a lot of times we look at it and figure out that the cancer is bigger than what we expected. >> that's what people call it. actually like a cancer, that the

weakening of that bar. the expansion of that bar cracks the cement. >> absolutely. and in the old buildings, we used beach sand with more salt in it. so the corrosion is even greater. but at the end of the day, for this to crash like this is a very unique and special situation. you can see, the stealel is inside, and the steel generally speaking, once you start to clean it up, we find more of the cancer within it. >> what do you make of -- we've heard there were engineers who looked at this building in this part of this certification thing. they wrote up a report. there was planning being done on the roof, as well. how serious an inspection is it for a certification like this that would it catch -- should it have caught issues like what may have led to this?

>> first of all, the statute of a 40-year is going to be one of the best practices in the world. like in california, we don't have something like that. and especially if the major corrosion going on in a column, you will see cracks in a column, so a wall or four. you will see the potential risk exist. but, again rebar is the inside of concrete and there is the finish around it. you have to kind of get down into the heart of it to see what's going on. i think that eventually, what's going to happen here is it's going to get down to the failure mode and you can simulate how it

actually gets down and why it happened. that will be definitely happening down the road. >> right. well, kit miamoto, i appreciate your time. and i understand you know my friend, jean mark in haiti. kobe, thank you so much. appreciate your expertise. >> thank you. up next, from here in surfside, as the rescue effort continues, the tight-knit jewish community have come together to help one another. some family members of a local synagogue are still missing. our randi kaye joins us with that when we continue. do your c? (naj) because as a fiduciary, it's our responsibility to always put clients first. (other money manager) so you do it because you have to? (naj) no, we do it because it's the right thing to do. we help clients enjoy a comfortable retirement. (other money manager) sounds like a big responsibility. (naj) one that we don't take lightly. it's why our fees are structured so we do better when our clients do better.

as the second day of this enormous rervegt continues, we want to focus on the especially close jewish community that surrounds surfside. they're leaning on religious leaders for support. randi kaye joins uh now with more. i know you spoke to a rabbi from this area. >> i spoke with rabbi lipskar. he tells me that he believes at least 20 people that are associated with his synagogue are missing, possibly in that rubble pile, ages from 20 years old to 60 years old. and he's been spending some time over the last couple of days with one woman who believes that she is missing seven of her own family members. and this is what he told me about their conversation.

>> the one that's really touching me the most is this -- the family came for a funeral of a dear friend of theirs and multiple family members were staying in that building. they have apartments there. and are now missing seven or eight family members. i've never seen the strength of a mother that herself went through her own miraculous recovery from a devastating disease and she's completely distraught that her daughter came for a furniture for someone, a dear friend, and she was there because she said to me, her daughter is the only one that could bring solace to others and so that story continuously resonates with me, because i'm just blown away by her faith and by her strength. even through her breaking down. i think that's her strength. >> earlier, i spoke to the family of a young man who came

with his girlfriend for that funeral. was the rabbi especially close to anyone who might be missing? >> yeah, he told me about another couple, both who are about 26 years old, and also, a doctor of their community. he is especially close to one couple. they're the parents of his childhood friend who he grew up with, knew this boy's parents very women, knew this older couple very well. and he is really just personally devastated by the fact that they're missing. and we talked about them as well today. >> obviously, my dear friends that are from here, that i grew up with my whole life, to watch the family's pain, it's hard for me to describe, because i know them. the parents, the brother, the sister, and it's been heart wrenching, the not knowing and not being able to really deal

with this magnitude to have the tragedy? >> i knew them since afs little boy. >> what can you tell me about them? >> amazing people, the house was always open, warm, the kids were open. they have taken different paths in their lives, but a family that has been a part of my life since i can remember. i stayed at their home many times. >> and he also told me, anderson, that his friend who he's been talking about who has been missing his parents, she was trying to talk to his own son and talk about where his grandparents are. for us as adults, it's hard to comprehend what happened here. for this man to try to explain it to his son, and to share some of how he tried to do that and this is just heartbreaking. >> so one of my childhood friends, he told me his son last night, i was at his house at 1:45 in the morning. and he says, what am i telling my son? he wants to know how he can go to sleep when our grandfather and grandmother are laying in

the rubble. and dirt. how are we not there pulling off the cement blocks and bricks? and i said, it's -- it's -- there's no words to just give them a hug. give them a hug, a kiss, and say, we're here as a family together. >> he just wanted to get out there on his own and dig through the rubble to try to find his grandfather. but the community is pulling together. he has about 5,000 or 6,000 individual donations. people are bringing pillows and crash and blankets, because many of these families are homeless, anderson. they have nowhere to go. >> it's time like this where a faith community can really make such a big difference in people's lives. randi, thank you so much. we'll be right back. we have more. how you can help the people here. we'll be right back. that delicious scramble was microwaved? get outta here. everybody's a skeptic. wright brothers? more like, yeah right, brothers! get outta here!

it's not crazy. it's a scramble. just crack an egg. for people living with h-i-v, keep being you. and ask your doctor about biktarvy. biktarvy is a complete, one-pill, once-a-day treatment used for h-i-v in certain adults.

it's not a cure, but with one small pill, biktarvy fights h-i-v to help you get to and stay undetectable. that's when the amount of virus is so low it cannot be measured by a lab test. research shows people who take h-i-v treatment every day and get to and stay undetectable can no longer transmit h-i-v through sex. serious side effects can occur, including kidney problems and kidney failure. rare, life-threatening side effects include a buildup of lactic acid and liver problems. do not take biktarvy if you take dofetilide or rifampin. tell your doctor about all the medicines and supplements you take, if you are pregnant or breastfeeding, or if you have kidney or liver problems, including hepatitis. if you have hepatitis b, do not stop taking biktarvy without talking to your doctor. common side effects were diarrhea, nausea, and headache. if you're living with hiv, keep loving who you are. and ask your doctor if biktarvy is right for you. no, he's not in his room. ♪

miami. chris? >> anderson, appreciate it. thank you very much. of course, i am chris cuomo and welcome to prime-time. it's good to be with you, brother, as always. we are live in surfside, florida, tonight, continuing our coverage. look, these are people dealing with the agony of the unknown. this community has come together, but there is a lot of hurt here. and it doesn't stop at the site. over my shoulder, what's happening there is unlike anything i've ever seen in this country before, except for 9/11. and that was a different circumstances precipitated that. the scale was very different. i just got the privilege of a walk-through at the site and i watched every aspect of the operation that is happening. and there are a few things noornt to say right off the top now about 48 hours in. the idea that there are not resources here is absurd. the idea that this is not work that's moving quickly is demonstrably false. this work by its nature is methodical. there are people who could be alive and the faster
