geej. and thanks for. >> jimmy:ing pus .it sounds like a plot from a hollywood thriller. new york spared from disaster in the nick of time. new details on how the suspected boston bombers were reportedly planning to attack times square this last week. as new yorkers shutter at the thought at what could have been, brian ross uncovers the alleged deadly plan gone awry mere hours before detonation. >> juju, what the new york mayor and police commissioner said thursday, dmork just missed being attacked by the accused boston bombers they arnt payly sought to maim and kill again. >> the fact is is new york city

remains a prime target for those who hate america and want to kill americans. >> and no target seems more attractive than times square. the surviving brother told the fbi he and his holder brother made the decision to head here one week ago tonight. to carry off a second attack at this crowded cross roads. >> the boston marathon bombers planned to travel to manhattan to detonate their remaining bombs in sometimes square. >> investigators say it was a spur of the moment decision by the brother ps. >> they discussed this while driving around in the suv that they hijacked after they shot and killed an mit police officer in cambridge. >> but new york was spared, officials say, when the two bombers had to stop for gas in the hijacked car and the younger brother, 19-year-old dzhokhar tar nevada went inside for snacks. it was the turning point. >> the driver used the opportunity to escape and call

the police. that eventually led to the shootout in watertown. >> hand grenades and automatic gun fire. >> reporter: that shootout captured in these still photos involved a violent gun fight. authorities say the two had at least six unexploded bombs, including a pressure cooker device. >> reports that they are explosives here at the scene. >> just some of what might have been used in times square. >> they had built these additional explosives and we know they had the capacity to carry out the attacks. we don't know if they would have been able to stop the terrorists if they rooifed hooer in boston, we're just thankful we didn't have to find out the answer. >> the officials said the 19-year-old brother first told the fbi he and his brother were just going to new york to party, as he did twice last year with some of his college friends, sween this online photo, posted oan russian social network site.

but in a second hospital interview, dzhokhar told a different story. more awake, speaking in his own voice to the agents. >> he was more lucid in the second interview, and was more expansive, giving more ge tails. >> the younger tsarnaev was reportedly questioned for about 16 hours before fbi agents were told they had to stop and read him his legal rights, according to republican congressman peter king of new york. >> it was a tremendous amount of information we don't know, and i can only know we would have gotten some 06 that information if the interrogation could have gone on. my understanding was h the interrogation was going to last about 48 hours. it was ended by the judge after 16 hours. >> times square has been targeted before. in 2010, another self-radicalized jihadist drove a car packed with explosives on times square. his bombs including one of those pressure cooker devices all

failed to detonate. this is prime time in times square. office workers, people going out to dinner or trying to rush to catch a broadway show. i'm joined here by former new york city police detective who worked terrorism cases for years. if the bombing had been planted here were the kinds use in the mir on this, what would have the effects? >> probably more devastating than boston. everybody there was focused in one direction. people were just moving about. the problem we have, at least one score or two scores of casualties. and twice that number wound popped. >> new york does have an extensive surveillance camera operation in place here in timessquare. >> h. >> the attacks in boston i think demonstrate just how valuable those cameras can be.

>> with so much going on, so many distractions, a bag with a bomb in it might well go undetected. in this crowd right now, mostly all tour iss, milling around, looki looking up, not knowing where they are, it's an ideal setting. shtly thereafter.y went off >> the major said today, we don't know if we could have stopped them if they got this far. he counted on the surveillance cameras. >> what do you think? surveillance cameras are great, but they're an investigative tool. they tell us what happened before, during and after and who did it. but they're not a deterrent. >> the cameras were used later to identify the two suspected bombers but they did not stop them. the younger of the alleged bombers dzhokhar with his white cap worn backwards put his bag down at the feet of a group that included children. and then ten seconds later, it was december detonated.

>> the fbi says talk of going to new york was just that, talk. even so, officials here say their only course of action is to respond to any threat. better safe, they say, than sorry. juju. >> the brothers tsnaev, why their mother said tamerlan and dzhokhar didn't do it.

authorities are examining every microscopic detail of sus spektded boston bombers lives. and the people they're most curious to hear from -- family members who tonight are speaking out. for the first time, "nightline" hears from their elusive center. their words, woven into a complex tapestry of mistrust and anger provide a window into the upbringing of these alleged terrorist terrorists. >> they were talking about him being killed. >> at a tearful press conference, the mother of tamerlan and dzhokhar forcefully denied her sons had anything to do with the boston make author bombing that wounded three and wounded 264 people. >> i'm sure my kids were not involved with anything. >> with her husband, the father of the boys alongside her, she blamed america for her sorrows.

>> why did i even go there? why? i thought america is going to protect us, our kids, is going to be safe for any reason. but it happened. america took my kids away from me. only america. >> she also dismissed reports that her younger son dzhokhar had already spoken ant how the brothers planned the attack. questioned the voracity of news reports. visibly angered, they commanded more evidence, as well as proof that their eldest son tamerlan was not killed by police after being captured alive. >> he was alive. why did they need to kill him? why not send him, whatever? they cited videos claiming to show tamerlan being caught by

police following a picture of a gruesome, bloody body. >> i wanted to scream. to scream to the whole world. what did you do? what have you done with my son? >> back in new jersey, the suspect's elusive sister bella broke her silence. reaching out to me via text, sending youtube videos suggesting her brothers were set up. she also sent me this picture along with the text that read, not my brother. now investigators are looking for clues into how and why the brothers who lived in america over a decade could have turned on the nation so violently. the family ethnic chechens who immigrated to the united states in 2002. though the parents returned to dagestan last year while their sons and two daughters stayed in the u.s. while their mother lived in the united states, a picture is emerging of a woman increasingly disillusioned with her adoptive

homeland. one of her clients said while she was a friendly and dedicated mother, she became increasingly allowed writing she thought 9/11 was purposefully created by the american government to make america hate muslims. she had never worn a hijab by working at the spa. and i was really surprised. then last june, tsarnaev was accused of stealing clothes. her arrest warrant is sdil outstanding. it was around this time that tamerlan also started taking a deeper interest in islam. investigators are now focusing on a trip he took back to russia last year. but at the press conference today, the tsarnaevs insist the trip was simply to see family

and attend a relative's wedding. his father said it was impossible for him to meet with militanting during his six-month visit. >> i was the first reporter to speak with anzar tsarnaev just last friday. he insisted his sons were not involved in the attack and kept asking for details about his younger son dzhokhar. i spoke with him again this morning when he told me he planned to travel to the u.s. as early as tomorrow. presumably without his wife who is facing that arrest warrant. though investigators are likely want to speak with him, experts say he may not have to. >> he doesn't have to talk to a soul. if he wants to the fbi he will, or could. or any other law enforcement official. but he can choose and say no to everyone, claim his son's body and go back to russia. >> meanwhile, the fbi is in dagestan working with russian

authoritie authorities looking for any clues to shed light on what happened to her family. >> the fbi is probably trying to get as much intelligence as they can before they go to the russians to talk about interviewing parents. so if there is no indication that the parents have any involvement in the case, but they have knowledge or history about tamerlan's radicalization, for example, those things can basically wait. >> asked if she would ever accept her son's alleged role in the bombings, mrs. tsarnaev's answer was clear. >> no, i don't. and i won't. never. >> our thanks 6. next, through chaos and back. a boston bombing amputee is reunited with the hero who rescued her. [ sally ] my antidepressant worked hard to help with my depression. but sometimes, i still struggled to get going,

even get through the day. so i was honest with my doctor. i told her i'd been feeling stuck for a long time. she said that for some people, an antidepressant alone only helps so much and suggested we add abilify (aripiprazole). she said that by taking both, some people had symptom improvement as early as 1 to 2 weeks. i wish i'd talked to my doctor sooner. [ female announcer ] abilify is not for everyone. call your doctor if your depression worsens or you have unusual changes in behavior, or thoughts of suicide. antidepressants can increase these in children, teens and young adults. elderly dementia patients taking abilify have an increased risk of death or stroke. call your doctor if you have high fever, stiff muscles and confusion to address a possible life-threatening condition. or if you have uncontrollable muscle movements, as these could become permanent. high blood sugar has been reported with abilify and medicines like it and in extreme cases can lead to coma or death. other risks include increased cholesterol, weight gain, decreases in white blood cells, which can be serious, dizziness on standing, seizures, trouble swallowing, and impaired judgment or motor skills.

[ sally ] since adding abilify, i feel better. abilify and my antidepressant make a pretty good team.

hanging out with friends after a red sox game, shcebrated an annual gathering without any knowledge of the danger that lurked just a few feet away. the bomb shattered her foot that day but not her spirit. here's lindsay david. >> reporter: it wasn't so much what heather abbott lost on marathon monday that captivated those who haeeard her story tod. it was her smile, her optimism three days after having her left foot and part of her leg amp hitted. >> it's something i wouldn't wish upon myself or anyone else, it's really not as bad as i thought it could have been. i really think i'm going to be able to live my life in a normal way eventually went i get a prosthesis. >> reporter: from her hospital bed, the 38-year-old recounted the moment the first bomb explode exploded. she just left the red sox game and was entering the boston marathon finish line with her friends. >> i remember turning around and

looking and seeing smoke and people screaming. it immediately reminded me of 9/11. i was on the ground. everyone was running for the back of the bar, to the exit. i felt like my foot was on fire. i knew i couldn't stand up. and i didn't know what to do. i was screaming somebody please help me. >> this is who saved her, former linebacker matt chatham. >> she was losing an incredible amount of blood. i could still see her face. >> with her consent, doctors removed her leg from just below the knee. >> i said to myself, i just need to make the decision. and the best case scenario seems to be to have the amp tigs.

it's only going tor difficu be for a short period of time and then it's going to get better. >> reporter: she says she's not angry and doesn't even think about the suspects. >> i don't even know how to pronounce their names. i haven't watched tv since the incident. and i think that's one of the things that kind of helped me get through this, just focus on my recovery and, you know, how to proceed with my life. >> reporter: last week, her bedside was crowded by one more visitor, the first lady. >> she talked about the fact that she typically only gives this certain coin out to military personnel who are injured and she actually gave one to me. so that was really nice. >> reporter: but it's what her friends and family have gwynn her that she says is helping her stay upbeat. >> it's so hard for me to focus on anything negative because they're always around. with with the situation i'm faced with, it's not going to change. so for me

negative is a waste of time to me. >> in two weeks she'll get her cast off. she's already counting down the leg whence she has her now prosthetic limb when she plans to caulk in heels again. >> our best to heather abbott. from the white house to capitol hill. a consensus seems to be building that the syrian government has crossed a red line. intelligence reports suggest the assad regime used chemical weapons in the silver war ravaging parts of syria. not long ago, the u.s. vowed intervention should syria wage chemical attacks. so what do you think? how should america respond? you can weigh in on the facebook page or tweet us at "nightline" or at jujuchangabc world news now is coming up with breaking news.
