>> we basically surrounded the school and started running into different areas. some of this has been cleaned out due to the search and rescue efforts. literally just climbing over debris. people were yelling for help. so pulling people out as quickly as possible. and that went on literally for hours. >> this was a hall of classrooms that led to -- >> classrooms on each side. >> connected? >> that was a wall there, a classroom straight ahead. there was classrooms out here. you can see there's still tile. >> right. it's just gone. >> this classroom is gone. these classrooms are all gone. >> more on the front side here too, anywhere we see tile? >> you can see the door leading into what was the classroom. >> the back wall with the board. that's the front wall of the school there? >> front wall would have been there, yes. >> is there a place in the school where people fared better? >> you can see where there's still walls standing up. obviously that corner, the main part of the tornado came through this way. so this is the area that took the most as it went through this part here. so that's -- yuck see where the walls are standing and where they're not. 460-something students. unfortunately, we did lose seven. but by looking at the damage it's a miracle that we didn't lose a lot more. and none of this has been touched. this is what it looked like. there hasn't been tractors moving anything. this is how it landed. people have been through, there's nobody left if. >> this has been searched. we had to go through all of this. this goes for 15 miles the other way, just like this. >> 15 miles? >> just like this. >> 15 miles just like this? >> 15 miles, yes. >> reporter: the damage there just so staggering. of course, the devastation at plaza towers elementary school weighing so heavily on everyone, the loss of seven young lives weighing on everyone here. it is weighing particularly heavy on one tornado survivor who rushed to the plaza towers elementary school with the hopes of saving some young children. pamela brown is here with that part of the story. >> we've talked to so many people who right after the tornado, they wanted to help. they rushed wherever they could to help. i spoke to one resident in moore, oklahoma, who did just that. he went to plaza towers elementary school hoping to save lives. what he saw still haunts him. >> reporter: moores dent adam baker is big a hand to a close friend whose home was flattened by monday's catastrophic tornado. it's helping him cope after he found himself helpless in the face of tragedy at plaza towers elementary school. >> it's just -- utter devastation. i mean, i don't know if there's really a way to describe it. >> reporter: right after the storm hit, he was one of many who rushed to plaza towers to find loved ones. he desperately searched for his nephew and any other survivors. and you went there in hopes of rescuing people? >> yeah. and i -- didn't really get to, i guess. i -- i tried, though. that's all i can do. >> reporter: instead, he encountered unspeakable horror. four children buried under the massive debris of the collapsed school. suffocated by its shear weight. >> they probably would have made fit they weren't pinned. >> reporter: how were they pinned? >> pinned by different debris. desks. two by fours. pieces of metal. >> reporter: the students were not found in a basement as officials initially believed. do you think had there been an underground shelter these lives could have been saved? >> oh, yeah, most definitely. underground shelters are some of the best things to have in a tornado. >> reporter: still, there are not enough of them. even in tornado-stricken oklahoma. schools aren't required to have underground shelters. the main reasons, the high cost of retrofitting the schools and the porous soil. >> it's about the money. and the statistics. an f-5 tornado is very rare, 1% to 2% of the tornados. they don't happen very often, same reason they don't have safe rooms for earth quabs. they don't work all the time. >> reporter: a painful truth for mickey dixon davis who lost her son kyle at plaza towers. >> with us living in oklahoma, tornado shelters should be in every school. it should be -- you know, there should be a place that if this ever happened again during school that kids can get to a safe place. that we don't have to sit there and go through rubble and rubble and rubble and -- and -- and may not ever find what we're looking for. >> reporter: a feeling that adam baker knows all too well. >> i pulled them out. and basically just tried to put them in a row. respect 33 as i could. >> reporter: what was that like for you? >> terrible for me. but it's my duty as an american. it's a hole in your heart. just to see these little broken bodies. >> just getting chills to hear that. the national weather service by the way has confirmed at this point the school is the only spot where they can confirm the ef 5 strength winds. winds of 200 miles per hour. or more. which isn't surprising when you see all of that devastation and what happened there. >> when you heard from the city mayor saying they would hope to have shelters in all these schools, i talked to parents of one of the victims, one of the little girls who died, they wish there was a shelter in that school. that's something everyone here is talking about. >> easier said that done but in light of what happened, you're seeing online petitions from residents, you're seeing state legislators saying, look, we need to do something, let's propose some legislation. we could see some change. >> thank for being here, we appreciate it. still ahead, terror on the streets of london. a deadly attack on a man thought to be a british soldier, an attack in broad daylight. the country on high alert right now. a live report coming up. the fbi linking dead boston marathon bombing suspect tamerlan saw her 95 to a triple murder two years ago. startling new information next. ♪ let me play among the stars ♪ and let me see what spring is like ♪ ♪ on jupiter and mars ♪ in other words [ male announcer ] the classic is back. ♪ i love [ male announcer ] the all-new chevrolet impala. chevrolet. find new roads. ♪ you as part of a heart healthy diet. that's true. ...but you still have to go to the gym. ♪ the one and only, cheerios ♪ the one and only, cheerios at university of phoenix we kis where it can take you.cation (now arriving: city hospital) which is why we're proud to help connect our students with leading employers across the nation.

>> all we know at this point is that they're working on the investigation. two suspects are now in custody. they're under arrest, in separate hospitals. i'm right by the police cordon. this was actually the scene of the crime about 100 meters or so behind me. i apologize for the noise, a helicopter overhead. but basically what we know is that the man, young man who was killed, we believe is a serving british soldier. we do not know, he has not been formally identified, we also don't know the names of the attackers yet. all we have really is that video you saw, that incredible video where he seems to be asking bystanders to tape the murder and also to take his statement. it really is some stunning video footage. i also have with us now a guest, and this is graham wilder. graham, you were an eyewitness to this, in fact, you live just three doors down from where this killing happened. what happened? >> well, i mean, as i said, i come out from where we live just up the road there. as i turn i see the actual car on the pavement. so i just carried on driving because i had to go where i actually live. and that's where i thought it was just a traffic accident. i see a geezer laying down against the wall and i see two people leaning over him. and i presumed they were trying to resuscitate him, that's what they looked like they were doing. i went and parked the car up in the garage. and as i parked the car in the garage, we start to walk up towards where it was. and a lorry pulled up and a little car pulled up then he come out and started saying, phone 999, phone the police, whatever. that's when he actually pulled the weapon, the handgun out, waving it about. the geezer in the car sped off. >> so there was a man with a gun. >> yeah. he was dressed all in black. he was the tall, black guy. he was over 6 foot. he had the handgun. so i backed off towards my back gate. as i was on the phone to the police on 999, i was talking to them. but then as i was talking to them a bunch of schoolkids come up through the alleyway. between the houses. >> horrific scene. >> get in, there's someone up there with a handgun. i actually seen the handgun in his hand. >> thank you very much. that's very vivid description of what happened. as you point out, he had a gun, and in fact, he fired it, i believe, and then he -- police were able to shoot both of the attackers serious injuring them and they're now in the hospital. thank you very much. as you can see, i mean, this was an incredibly traumatic event that happened. eyewitnesses seeing all this. it really is a very grisly, shocking event, christine. >> i know. even looked like passersby didn't even know what was going on. the video of this man, one of the suspects, ranting about -- ranting about why he did that. a woman is walking by, pulling her groceries or pulling her bag. just a very, very odd and disturbing scene. atika, thank you so much. tamerlan tsarnaev, the boston marathon suspect, laepged to a gruesome triple murder. a chechen man killed by an fbi agent wednesday in orlando confessed to slashing those victims' thoets in 2011 and that man claims tsarnaev also participated in the murders. john zarrella is live in orlando with the details on this. what can you tell us? >> reporter: good morning, christine. this is still a crime scene more than 24 hours after ibragim todashev was shot and killed. turns out the fbi had their eyes on him within days of the boston bombings. the common thread between todashev and one of the bombings appears to be waltham, massachusetts. sources tell cnn this man knew boston bombing sources tsarnaev and confessed to being "directly involved in a brutal triple 2011 drug-related murder in waltham, massachusetts. a federal law enforcement official tells cnn that todashev also implicated tamerlan tsarnaev in the murders. todashev is dead, shot during questioning by an fbi agent and two state police officers in the kitchen of his orlando apartment. law enforcement sources told cnn todashev confessed to his role in the triple murder then became violent and attacked the fbi act. he was then shot and killed. a friend said todashev knew the boston suspects but that was all. >> he knew them two years ago when he used to live in boston. he knew them. he didn't -- he wasn't real close friends, just happened to know them. and i guess it was his fault, one of the waltham, massachusetts, victims. the fbi is checking to see if they can match his and todashev's dna to the crime scene. there were other decks between the men. sources tell cnn they came from the same region of chechnya. both men were in mixed martial arts in a studio in boston and on a mixed martial arts website. tamerlan tsarnaev's phone number was found in tosashev's cell. earlier this month he was charged with batly after getting in a fight over a parking space at a local mall. while it appears todashev was a violent man, his connection to the boston suspects may go no further than a murder case and friendship. todashev had bought a ticket to go to russia on may 27th. the fbi had known about that and told him, don't get on that flight. >> what an odd turn in all this. john zarrella, thanks. developing right now, a humongous sell-off of stocks in foreign markets and it will have an effect on you. i'll tell you what's driving the sell-off and what will happen to your 401(k) today. n, there's fusion proglide. our micro thin blades are thinner than a surgeon's scalpel for our gentlest shave. switch to fusion proglide. gillette. the best a man can get. switch to f[growl]roglide. we used to live with a bear. we'd always have to go everywhere with it. get in the front. we drive. it was so embarrasing that we just wanted to say, well, go away. shoo bear. but we can't really tell bears what to do. moooooommmmmm!!! then one day, it was just gone. mom!
