bottom of the hour now. welcome back. i'm john berman. >> and i'm zoraida sambol. nice to have you with us this morning. >> let's get right up to speed on the boston bombings. the only person who knows the motive for the attack is sedated now. dzhokhar tsarnaev under heavy guard this morning at a boston hospital. officials say the 19-year-old suspect will face federal terrorism charges, possibly murder charges here in massachusetts.

meanwhile, at least 57 bombing victims are still in the hospital. two of them in critical condition. we now also know at least six bombs, six were found at the scene of the shootout early friday and left the other suspect dead. during that battle, officials say the surviving suspect drove a stolen car toward officers and ended up dragging his own brother down the street. >> brian todd joins us now with a final recap of moments that brought down dzhokhar tsarnaev. >> reporter: as he was cornered, dzhokhar tsarnaev, police say, engaged them with gunfire. it it went on for several minutes and police lobbed in flash-bangs to stun him. in the end, authorities showed their determination to capture the suspect alive. listen to officers negotiating with him as he's holed up inside a boat in a backyard in

watertown. >> come out with your hands up. >> reporter: we snaked through allies to get to within a couple hundred yards of the poet. during negotiations there was a word of reassurance and an appeal to someone they knew was in pain. >> we know you're bleeding and we know you're tired. >> reporter: as we shot this excleesive video police rushed us saying we were in the cross fire zone. it was just minutes later that police captured tsarnaev. he had lost blood, was weakened. these pictures show thermal imaging from a helicopter of the suspect as he hid in the boat. the entire neighborhood had been on lockdown. residents terrified as law enforcement went door to door. after the standoff we spoke to neighbors. here on cyprus street, this is one of the houses where police were combing through the neighborhood looking for the suspect. this is eddie beck's house. he took us through what it was like when s.w.a.t. teams went through. >> they came in and searched the

living room area, dining room. went there through all the bedrooms, bathrooms, kitchen area. >> did they search cabinets? >> they didn't go through cabinet, but they went through all the bedroom closet doors and made their way through the back. >> he shared his own footage of the s.w.a.t. teams combing through his house. during the moments they didn't know where he was. beck got a chill just thinking about it. >> knowing they had him surrounded and so close to our neighborhood, it made us think he might have been here at nighttime and they flushed him out into that area. >> reporter: vivian lives very close to the house where tsarnaev was cornered. >> how do you feel now that it's over? >> it's surreal. i think i'm numb. i don't really feel -- i guess i can't believe all this happened. i know it's happening, but i'm very happy that it's over and they got him. >> reporter: a sentiment echoed

by thousands of her neighbors in watertown. cheering police as they pulled out after the arrest. brian todd, cnn, watertown, massachusetts. >> that was at fenway park yesterday and people were still cheering police whenever they bump bumped into them. >> as they should. that was an inkrenl effort. >> london's marathon is happening this morning. more than 35,000 people will pass some of the world's most famous landmarks. >> runners honored a moment of silence for the victims. they wore black ribbons in their honor as well. here's a clip of that from the bbc. >> our senior international correspondent matthew chance is live near the tower bridge in london this morning. let's talk about all the extra security. what's being done to ensure the safety of the hundreds of thousands of people out today?

>> reporter: quite a lot according to the police force in lond london. they say they have stepped up the number of uniformed patrol officers by 40% compared to last year. but i have to say, you're not seeing a lot of police in uniform along the streets here in central london with the tens of thousands of runners running through the track right here. and the hundreds of thousands of spectators that have come out to show their support. but the police also say they haven't received any information about increased threats as a result of the boston attackeds. they are just trying to be out there to give people a visual kind of reassurance. also to be extra vigilant as well. it's a very festive mood that's taken a grip here along the london marathon route. it's a joyous occasion. it was that moment of silence that you just heard earlier at

the start of the race before it it began. in general you can hear the crowds are cheering. they are giving their support as much as they can to the runners as they go past. it's not just londoners here as well. people all around the world. we met ron taylor. he's from atlanta. he's come all the way from atlanta to be on cnn. you're here in london watching the marathon. all this cheering and festive atmosphere, do you think that's appropriate given what happened in boston? >> i don't think so. i think people would agree you can't go on. >> you think it is appropriate? >> i think it is appropriate to be cheering these guys on. this is all being done for charity. it needs to go on. >> reporter: what about the security situation? i mentioned the police have said they updated patrols. do you feel safe? >> perfectly safe. we have seen police here. i'm sure there are police we don't see. there are cameras everywhere.

perfectly safe. >> reporter: did you at any point consider not coming to the london marathon given what happened in boston? >> absolutely not. absolutely not. i thought we would be perfectly safe. i'm here with my wife and another couple and we didn't give it it a second thought. >> reporter: thanks so much for joining us here. a lot of people have turned out. a lot of people from the u.s. as well to watch what the organizers hope will be a very respectable and joyous london marathon. >> matthew, i have to tell you, it's great to hear the normalcy of the cheering that is happening over there. i know that some money is being raised to help the victims here of boston. can you tell us about that? >> reporter: the organizers of the london marathon were clear about that. they were saying for every runner that crosses the finish

line after that 26.2-mile event they will give two pounds, which is about $3 to give money to help out those most affected by the bomb attacks. they are also expecting to receive a lot of private donations as well. this is first and foremost a charity-raising event. people come here and get sponsorship and do that run. they give the money to the charity of their choice. a the lot of private individuals are giving their money to help the victims of those bomb attacks. >> we have to ask since it's london. what about the royals? will there be a royal presence at the race today? >> reporter: there already has been. they are not running in the marathon, but already prince harry has visited the finish line. he did that before the race finished to show his support for the stewards organizing the race

and to show his support to a certain extent to the people of bost boston. prince harry representing the royal family to show they are watching this closely. and everybody in britain is watching the marathon and watching them. >> matthew chance in london, thank you so much. we hear the cheering behind you. i'd like to think they are also cheering on matthew in his terrific report. thanks to him. the people of boston trying to get back to their regular routines, which of course, includes the boston red sox. stay here for must-see highlights from an emotional day at fenway park just ahead.

>> nothing like a little neil diamond at fenway. he took a red eye to get to the game. he landed, he went straight from the airport to the park and made it there just in time to sing "sweet caroline", the song that's become a theme song for the sox. >> a song that's been stuck in my head for 24 hours. it's a good one. if that wasn't enough to get. the crowd going, there was a ball game too. a phenomenal game. it was the first game played here since monday's bombings. it was the first time the green monster was open and it cshowed things getting back to normal. >> there's no better way for the city of boston to return to a sense of normalcy than a packed house at fenway park and that's what we saw yesterday. more than 35,000 strong were on hand to cheer on the red sox in their first game back since the

bombings. during an emotional pregame ceremony, the red sox honored all of those affected by monday's tragedy and the law enforcement who helped capture the two suspects. at the end of the ceremony, david ortiz took the mike to thank everyone and used strong words to deliver this message. >> this is our [ bleep ] city. and nobody going to dictate our freedom. stay strong, thank you. [ applause ] >> his uniform, the white jerseys, they wore special uniforms with boston across their chest. they didn't give much to cheer about until the eighth. a three-run shot into the bullpen. the crowd would go nuts. the red sox take the lead and hold on to get the win 4-3.

meanwhile over at garden, the bruins were back on the ice against the penguins that had been postponed on friday. the bruins wore state police hats and for the game both teams wore special patches on their jerseys pop though will be auctioned off tomorrow with proceeds going to the one fund, which benefits those affected by monday's marathon bombings. the celtics also wore special patches and warm-up shirts for yesterday's playoff opener in new york against the knicks. they led after three quarters, but would only score eight points in the fourth as they fell to the knicks. game two is tuesday night before it shifts back to boston for game three on friday. fenway will be rocking again today as the red sox play a double header to make up for friday's game. like most people in boston, you're pretty pleased with the team.

definitely picked a good time to go on a run. >> i just assume they won't lose for the rest of the season. that's my hope. andy, thanks so much. i do have to tell you. you heard david ortiz what he said and those people done like to use out loud. the fcc, the chairman of the fcc tweeted this. david ortiz spoke from the heart at today's red sox game. i stand with big poppy and the people of boston. so the fcc says just this once, it's okay. >> they are going to be okay with that. andy sholes, thank you so much. dzhokhar tsarnaev is sedated in a boston hospital. when he wakes up, investigators will have scores of questions for the only surviving suspect. up next a former sbeinterrogato will explain how to hunt for answers. verify and lock. command is locked.

[ cheers and applause ] welcome back. the celebration and sigh of relief when authorities capture one of the boston bombing suspects alive. >> the hope of course is that dzhokhar tsarnaev can answer the questions weighing on so many minds since monday's attack, and that question is why. >> and we're joined now from new york by avina pompora a veteran polygraph examiner. what is the key information we want to learn from this particular suspect? >> well, we want to learn why, right? we want to understand the

motive. why did they do this? and how did they do this? were they aided by others. is there any type of influence from outside the united states? >> so how do you get this suspect to talk? particularly when he's suffering this medical condition. assuming the intubation tube comes out, he won't be in the top condition, how will you get this information? >> the key thing is you mentioned is he's sedated. we have to make sure he's in a clear state of mind. that he is clear and think and can answer the questions. although he may not be able to vocalize his answers, there's ways to get the information through writings, drawings, typings, anything like that. we need to get him out of his sedated state, conscious so he

can speak to law enforcement clearly. >> so let's say he's not interested in talking. in your experience, how are some ways in which you would get him to answer your questions? >> so the key thing is you need a strong interviewer or interrogator. most people in this situation it's very difficult because everyone's had such a strong bias and personal sentiment to what happened. nobody can understand that. but if you are a true interrogator and interviewer, you go in objectively. you leave your biases at the door, check your emotions there and you are there truly to lift information out of this individual. and you do that by establishing rapport, trust and getting this individual somehow to trust in you to give you the information, to share with you what happened, their journey and how they got there. that is the key thing. >> we now know that the suspect has not been given his miranda warnings. and there's a lot of discussion about the legal avenues that

might be taken. but, evyenia, as an interroga r interrogator, how much do you care about the legal discussions going on and does that effect how you go about your job? >> yes, the legal aspect is very, very important. that comes from levels above you. so if the law does allow you to not ask those miranda rights, you can proceed. but you cannot make up the rules as you go. if you do not follow the law, if you do deviate from it, the things you do could cost the case ultimately. any confession you could get could be thrown out or dismissed or anything like that. you want to make sure that you do follow the law even though you may feel otherwise, we have to be careful. >> all right. an experienced interrogator, thank you so much for joining us. appreciate it. >> thank you.

>> we have some good news for all that flooding out west. we'll tell you what it is, your weather forecast coming up. hey! did you know that honey nut cheerios has oats that can help lower cholesterol? and it tastes good? sure does! wow. it's the honey, it makes it taste so... well, would you look at the time... what's the rush? be happy. be healthy.
