david mattingly, thank you very much. we'll be checking back in with david. the story is developing incredibly quickly since the top of the hour. >>> president obama is meeting with senate republicans at the white house at this moment. one of the topics being discussed is gun control. the sitdown comes hours after a major breakthrough. joe manchin and pat toomey announced a deal to expand background checks at gun shows and internet sails. manchin got very emotional while meeting with newtown families and talking about it. >> i can't imagine. >> very emotional. and one senator who is going to be key in helping the deal go ahead is georgia's johnny isaacson. he has an a rating from gun owners of america which called senator toomey who also has an a a sellout because of this deal. senator isaacson came "outfront" and told me while the bill has drawn the powerful gun lobby's ire, he is not concerned about the backlash. >> the most important record card i ever had is the one i got in elementary school and high school. anybody can give out grades if they want to tr

and david mattingly following the money trail. so many want answers to this question. how did the brothers support themselves? and how long did they collect welfare from the state of massachusetts? aaron mcpike is in rhode island. tamerlan tsarnaev's wife is there. investigators are asking how could she have not known about the bombs? and we'll go overseas to dagestan where nic robertson is, and has the latest on the meeting today between u.s. officials and the bomber's parents. and joe johns is in washington with new information about what russian officials told the fbi and the cia. some damning details about whether our intelligence agencies may have dropped the ball. i want to begin with deb in boston. deb, what do we know about this visit from the parents? >> reporter: yeah, this is news that we just got. came across a couple moments ago. we're being told that russian newspaper is reporting that the two parents are going to be leaving their homes and coming to the united states. now it's unclear exactly whether we're hearing it may be as early as tomorrow. this is

david mattingly is there, he's joining us now. david, what's the latest on this? >> reporter: anderson, this all went down 15 minutes ago. everyone here had hoped for a peaceful resolution to this. and that is not what happened here. the s.w.a.t. team had to make a move on this house to try to attack the captor, the man who was holding these four firefighters hostage in the home in the neighborhood behind me. what we were able to hear in the distance here was a series of explosions, concussions. it sounded like a concussion grenade that they used when they start to make a move on a hostage situation followed by what could have been tear gas. what we now find out is that when the officers went in, gunfire was exchanged between the officers and the man who was holding -- the gunman who was holding the firefighters hostage. that man was killed. and one police officer was wounded in the hand. it is not a life threatening injury. he's already been rushed from the scene to the hospital. right now we're told that all four of the firefighters that were inside sustained so

david mattingly joins us with late details and audio from one of the firefighters before this came todly conclusion. david, what's the latest? >> reporter: anderson, this all started out as a routine medical call. the firemen arrived on the scene, everything looked and seemed like they expected it to be. they took a gurney and their medical equipment inside the house, presumably to treat someone in medical distress. but that is not what they encountered. and just a few minutes later, this was heard over the radio, via scanner traffic. listen to what one of the firefighters was saying to his people back at the station. listen. >> we are in a situation where we have an armed person. and he is requesting certain -- certain utilities to be turned back on at his house. suspect is armed and we are in the room with him. >> reporter: very calm description of what was a very tense situation for those firemen. eventually one of them was let go to move the fire engine from in front of the man's house. but the four remained inside until the s.w.a.t. team came a short time ago. all four firemen ar

cnn's david mattingly is in west, texas, as well. david, do authorities have a handle yet on how many people might be missing? >> reporter: well, here we are about 17 hours after that blast, and the answer is, no. and there's a couple of reasons for that. first of all, there's search and rescue operations that are ongoing right now. you just saw how badly damaged the buildings are a good distance away from the blast site. 50 to 60 homes, we were told, have been damaged. roofs peeled back, walls collapsed. some of these structures are just too dangerous for rescuers to go inside to conduct their search, so, they have to be shored up before anyone can go inside. the last thing you want right now is further injuries from people trying to help others. a second reason is in the chaos last night, there were some people who were able to just leave the scene after the explosion. they were lucky enough to be able to flee on their own. there were others like the injured of the ambulances, the police that showed up there at the scene, just putti

david mattingly is live for us tonight from suwannee, georgia with more. david? >> reporter: piers, this started as a standard sort of medical call. firefighters got the call that there was someone in medical distress. they showed up at this address, came out with their equipment, had a gurney, went inside the house. and at that point they realized there was something very wrong here. they encountered a man with some kind of weapon who then held him hostage for several hours. we were able to hear the voice of one of the firefighters after they encountered this man. this was from scanner traffic that was overheard as he was radioing back, telling everyone what the situation was that they ran into. listen. >> we are in a situation where we have a, uh -- an armed person. and he is requesting certain -- certain utilities to be turned back on at his house. and he is armed, and we are in the room with him. >> reporter: at this point, authorities saying that was the only demand this man made, was to have his utilities turned back on. negotiators, the s.w.a.t. team, show

. >> david mattingly is live in boston. i find the piece so amazing.hen you say you could be hit before you hear it. that means you could be dead before you hear it. this is something soldiers know but nothing that civilians would think about. what surprised you the most about this demonstration? >> just how power. this crude and cheap bomb really was. the fact it was able to send out whatever pieces of hardware was inside faster than the speed of sound making sure that you would be hit before you hear the sound of the explosion, that is what was truly surprising. we commissioned the experts at new mexico tech to do this demonstration for us. they were telling me that it usually takes less than $100 worth of materials and access to the internet for anyone to possibly try to build one of these. but these experts were careful in the way they were handling this because this was a very, very dangerous device. >> all right. david mattingly thank you very much. $100. that is just -- it's just incredible. stops you dead in your tracks when you think of how li

cnn commission and explosives expert to build a pressure cooker bomb, and david mattingly reports on learned. >> reporter: at this remote desert testing ground, experts from new mexico tech replicate and explode bombs used by terrorists. on this day, there is a sense of urgency. >> after boston, what are you worried about? could this be the future of domestic terrorism? >> you're always worried about copycats. are more and more people going to be using this? >> this is a pressure cooker bomb similar to the bombs in boston and we're to be set it off. >> eric, going to do the countdown? >> reporter: in the wrong hands we already know how deadly this bomb can be. and we're not taking any chances. for safety reasons, we've had to retreat to this mountaintop here. we are now over a quarter of a mile away from where we left that pressure cooker. but that is still not far enough to avoid flying shrapnel. so we're watching from inside a bunker. >> five, four, three, two, one. wow. that white smoke looks just like what we saw in boston. >> yep. >> i could feel it all the way up here. >> oh, y

david mattingly, cnn, new mexico. >> perspective on this.ning every day, stopping someone before they can commit an act like this is very difficult. more difficult than we even imagined sometimes. however, what made the difference at the marathon was how people responded after the bombs went off. tremendous energy, tremendous know-how and triage, and the more they understand about these bombs and what they can do, the better first responders can limit the impact and that's part of the equation how we stay safer. >>> we're going to take a break. emotions of anger, disbelief, heartbreak from the mother of the boston bombing suspects. she speaks out to cnn. what she says, when we come back. this day calls you. to fight chronic osteoarthritis pain. to fight chronic low back pain. to take action. to take the next step. today, you will know you did something for your pain. cymbalta can help. cymbalta is a pain reliever fda-approved to manage chronic musculoskeletal pain. one non-narcotic pill a day, every day, can help reduce this pain. tell your
