tonight on "nightline," the mastermind. how tamerlan tsarnaev apparently relied on welfare while the country plotting against the country that took him in. the president on 9/11 gave his reaction to america's latest attack. and from politics to painting to his brother's possible run. >> it would be great, you know? >> george and laura bush give abc news a look at life after the white house. and he has been called the frank sinatra of his generation. but this crooner's life hasn't always been about feeling good. we are on the town with michael buble.

>> few for joining us tonight. so much of the investigative energy is how could these two brothers turn on the country that took them in? a chilling trail left by tamerlan tsarnaev, the elder and apparent master mine. >> for a while, the man police considered the master mine of marathon bombings seemed like a normal young guy, the kind who

made videos of himself joking around in russian and posted them on youtube. who liked to wear fancy clothes, who was considered a hot shot boxer. the mystery, one in which we are gathering fresh clue tonight is how this man who came to this country for a letter life, where he got freedom, safety, education and even welfare checks, how this man allegedly turned on america so mercilessly. tamerlan tsarnaev didn't start out so menacing. here he is as a baby on iz h mom's lap. that's his dad to the left. this is tamerlan and his siblings. the little boy in front is his brother dzhokhar who would grow up to be his partner in terrorism. tamerlan moved to america from a poor and dangerous part of russia at age 14. he went to a good high school and showed a lot of promise as a boxer. but things started to go wrong

not long after he graduated from high school. this was a mug shot when he was arrested for allegedly slapping his then girlfriend. at the time he told police he was unemployed. he later met and married another woman named catherine. her friends have reportedly said tamerlan was abusive and controlling with her, too. it was around this time that tamerl tamerlan, who was never much keen on religion before started to take a deep interest in islam. >> what's happened is a terrible thing, but i know that my kids have nothing to do with it. i know it. i am mother. >> reporter: her mother says she pushed him in this direction because she wanted him to stop smoking and drinking so much. >> somebody radicalized them, but it's not my brother. >> reporter: but his uncle told us today there was another major person in tamerlan's life. a mysterious man known only as misha, a muslim convert as a

bald heavy set man with a red beard. tamerlan gave up boxing and his study of music. the idea that misha negatively affected her son is impossible. he started to attend this mosque here in cambridge are on a few occasions he actually got into public fights with the imam. >> he stood up and also challenged and actually call ed the preacher a hypocrite. >> the russian government asked the fbi to investigate tamerlan, worried he had links to extremists in that country. the fbi said it found no threat and shut down the investigation. perhaps what is now the most investigative period of tamerlan's life is the six-month trip in which he traveled russia last year.

a visit to his homeland. the fbi, which is now questioning tamerlan's parents over in russia wants to know whether the young man was reuid or trained by any local islamist groups during his time there. when he got back home, while he continued to subscribe to islam, he was a stay at home dad while his wife worked 80-hour weeks as a home health aid. they even went on welfare intermitte intermittently. but despite the fact that this country was supporting him and gave him so many opportunities, it appears he started planning his attacks several months ago. in february, he went to this fireworks shop in new hampshire. now in a hospital bed, tamerlan's little brother dzhokhar reportedly said they learned how to make a bomb right off the internet. days later with police on their

tail, they got into this gun fight with officers. that is them firing from behind their carjacked black mercedes suv, according to the man who took these pictures from his bedroom. the photographer said he could see tamerlan walk towards the officers firing until he went down and his brother got away. remarkably, tonight, police believe that during this entire shootout, the semiautomatic pistol in tamerlan's hand was the only gun that the brothers had. that gun was later recovered at the scene, which means that all day friday as the city of boston was shut down, the man holding it hostage, justifiably considered to be armed and dangerous was, at least as far as police could tell right now was an unarmed 19-year-old curled up and bleeding in the back of a boat. despite all the evidence, the boy's mother who pushed them towards religion in the first place believes they are innocent. >> my son was muslim, that's it. tonight, her younker son is

facing a criminal charge of using a weapons of mass destruction which could carry the death penalty. while tamerlan lies in a boston morgue. nobody has stepped forward to claim his body. for "nightline," this is dan harris. >> coming up next, singer michael buble on building a family and the goal he says he'll never be table to achieve. .

>> he has won three gamemys, sold 45 million albums and is expecting his first child. so everything seems to be coming up roses right now for 37-year-old michael buble. but for this big man star, there was a time when singing the words to "feeling good" was a lot easier than believing those words, as heed to cynthia mcfadden when they went on the town. >> reporter: this is michael buble. as his fans love him. polished, sophisticated, here seasoninging the barry gibbs hit "to love somebody." isn't it fun to be able to open your mouth and sound that way. >> i don't always sound that way. i prom you. >> reporter: i went on the town with the grammy winner who sold a whopping 45 million albums. >> there you are. very cute. >> reporter: last night in new

anti-love song. he's married and they're awaiting their first baby. >> reporter: do you sing to the baby? >> yes. >> reporter: what do you sing to the baby. ♪ everybody loves a baby that's why i'm in love you ♪ ♪ pretty baby pretty baby ♪ ♪ and i would like to be your brother sister mother dad ♪ >> they were introduced after one of his concerts. she spoke no english, he spoke no spanish. >> she walked with rodrigo. he makes brad pitt look like a fat turd. this is just great. the woman of my dreams and her disgustingly gorgeous husband or boyfriend. he looked at me and said no, we are not a couple. we are not together. we're friends. he said she leak likes you. she was on the pho wh her

mother saying in spanish, i've come to meet michael buble and this dude is gay. >> reporter: that impression didn't last long and she soon appeared in his video "i just haven't met you yet." >> i married my mother. i married the most wonderful, compassionate, loving, tough, tough woman. i think a strong woman makes you a way stronger man, i really do. the funny thing is henry knows it, too. even if he's not admitting it. inside henry is going, eh. >> there have been very strong men in his life, too. his father and his grandfather who he calls his idol. >> i look at them and i go, they are true gentlemen, really. as i'm having this baby, you know, it's a little boy. i just keep thinking god, i hope

that i can be as good as my grandpa and my dad were. >> but that doesn't mean the path has always been a smooth one. nearly five years ago after a long relationship, he and actress emily blunt called it quits and he fell apart. something he's brutally candid about. >> the breakup was the best and worst thing that ever happened to me. i call mid grandfather and said i'm dying here. i was having a hard time breathing. i was having such anxiety that i would sit there and he said sunshine, today's curse is tomorrow's bless popping. >> he displayed some of that attitude when i asked about reese witherspoon, accused of d disorderly conduct when her husband was pulled over for dui. the two sang a duet of "something stupid" on his new album. so she's had a rough 72 hours. have you talked to her? >> i have. >> reporter: and?

>> and i only hope that if i get into trouble and when i get into trouble that i handle myself with such grace and dignity. i love that she went to the movie premier. and she has no bigger fan that michael buble. >> so what professionally is left? what do you want that you don't have professionally? >> something i will never get. i will never get critical acclaim. i won't. i won't. there's nothing about liking a guy who sold 40 million records. it's cool to like somebody who sold 5,000 who's the underdog, who's the indy star. the greatest review i can get is when somebody pays their money across that counter and buys one of my records. ♪ beautiful day that's something i can live with. >> reporter: for "nightline" i'm cynthia mcfadden in new york. >> michael buble's album "to be loved" is in stores now. and coming up next, five years
