查納耶夫家的兄弟倆（另有兩名姊妹）是車臣族，來自俄羅斯一主要居民為穆斯林的地區，當地的分離主義者在蘇聯垮台後，1990年代打過兩場戰爭。

他們在達吉斯坦地區念書，這裡因為地理位置比鄰，在1990年代曾捲入車臣的暴力衝突。那時起，醞釀伊斯蘭主義暴動的達吉斯坦，成為關注的焦點。

住在多倫多的姑姑馬瑞．查納耶夫說，他們一家人在美國擁有難民身分。

弟弟佐哈2002年隨父母抵達美國。當時，3名兄長及姐妹留在哈薩克，後來才在美國團圓。後來，父親安佐與經常往返美國的母親回到達吉斯坦。

最重要的，據劍橋友人的說法，佐哈想受到大家的歡迎。哈佛大學與麻省理工學院都位在劍橋，這座城市除了學生及學者，還摻雜藍領勞工與新進移民。

朋友與熟人表示，他聽到每個人的笑話都會笑。他努力跟每個人相處，他喜歡嘻哈，樂天開朗；但個性緊張、不擅於社交，但不會讓人感到不快。另外，他不會動不動就談論政治。

一同就讀劍橋林吉與拉丁學校、在班上成績比佐哈要好的曼恩表示：「老實說，他非常非常的正常，沒有腔調，無論從哪邊看，他是個徹徹底底的美國年輕人。」

被喚作提米的哥哥塔默蘭，則顯得更不懂得社交。「我一個美國朋友都沒有。」塔默蘭2010年在《評論》雜誌的人物採訪中這麼說過：「我不了解他們。」《評論》是波士頓大學傳播學院發行的刊物。

25歲青年顧問瓦斯蓋茲，曾是塔默蘭的同學，他住在距離查納耶夫家兩個街區的地方，他對塔默蘭有著不同的印象。「他就是一名高大友善的人。」瓦斯蓋茲：「他有幽默感。」

塔默蘭已經結婚，妻子叫羅素，並育有一名年幼的女兒。他的姑姑說，對於自己的小孩，他感到「很幸福」。

「我們開始無法理解這個恐怖悲劇是如何發生的。」羅素的家人在聲明中表示：「愛國日發生這起恐怖事件後，我們了解到自己從未真正認識塔默蘭．查納耶夫。」

塔默蘭曾就讀波士頓的邦克山社區學苑，是會計系的半職學生，他念了3學期：2006年秋、2007春及2008秋季。

塔默蘭2004年在麻州羅艾爾附近，贏得業餘拳擊賽的金手套獎，當時他告訴當地一家報紙：「我愛美國……美國有很多工作。」「這些是俄羅斯沒有的，只要你願意工作，就有機會賺到錢。」

《評論》雜誌提到，塔默蘭想參加奧運，且如果不能代表獨立的車臣參賽，「寧可替美國出征，而非俄羅斯」。

根據雜誌對這名業餘拳擊手的人物專訪，塔默蘭不菸不酒，並說「真主說不碰酒精」。

據弟弟友人們的描述，佐哈則是個沒有半點移民影子的人：事實上佐哈沒口音，他穿運動衫。他跟學校裡的穆斯林圈子的人沒有任何往來。

佐哈就讀的公立學校劍橋林吉與拉丁學校，是當地學生組成最多元的學校之一。在校學生有移民之子，也有哈佛教授的小孩。

曾與佐哈一同加入劍橋林吉與拉丁學校長曲棍球隊的泰勒．康林表示：「我一直都能以同理心對待他，因為就我看來，他就是一個真得想要獲得別人接納的年輕人。」

以前的同學們，聽到「討人喜愛、體貼的」、後來註冊就讀薩諸塞大學達特茅斯分校的佐哈竟會涉入這起爆炸案，十分驚訝。

「對我們來說，他就是典型的林吉年輕人，實際上也比我們這些人來得更友善、更溫和。」曼恩說：「但很顯然，他有秘密。」（路透）

They dressed like typical American teenagers, enjoyed playing sports and strived to fit in after arriving in the United States with their family from the southern Russian province of Dagestan a decade ago.

The schoolmates, teachers and neighbors of Dzhokhar and Tamerlan Tsarnaev said they saw little sign of radicalism（1） - or anything extraordinary - to explain why the ethnic Chechen brothers would carry out the twin bombings that killed three people and wounded 176 at the Boston Marathon on Monday.

Tamerlan, 26, who dreamed of Olympic boxing glory and appeared to have become a more observant Muslim in recent years, was killed in a shootout with police late on Thursday. Dzhokhar, 19, who was a high school wrestler, was captured by police Friday night after a manhunt（2） that virtually shut down Boston.

The physical journey of the pair from Russia to Cambridge, Massachusetts, is fairly well-documented. But the psychological journey that might have led them to carry out the worst bomb attack on U.S. soil since the plane hijackings on September 11, 2001, is largely an enigma（3）.

The Tsarnaev brothers, who have two sisters, are ethnic Chechen, from a predominately Muslim region of Russia where separatists（4） fought two wars in the 1990s after the fall of the Soviet Union.

They were schooled in Dagestan, a neighboring region that was drawn into Chechnya's violence during the 1990s and has since become the focal point for a simmering Islamist insurgency.

Their aunt, Maret Tsarnaeva, who lives in Toronto, said the family had refugee status in the United States.

The younger brother arrived in 2002 with his parents. At the time, his three siblings were in Kazakhstan but later united with Dzhokhar in the United States. The father, Anzor, later went back to Dagestan with the mother, who has traveled back and forth to the United States.

More than anything, Dzhokhar wanted to be popular, according to those who knew him in Cambridge, home of Harvard University and Massachusetts Institute of Technology, a city where students and academics mix easily with blue-collar workers and recent immigrants.

Friends and acquaintances say he laughed at everyone's jokes. He tried hard to get along with everybody. He liked hip hop. He was cheery, nervous and socially awkward - but not in a way that made people uncomfortable. And he didn't talk about politics much.

"Seriously, he was so, so normal, no accent, an all-American kid in every measurable sense of the word," said Nate Mann who was in the class above the younger Tsarnaev at Cambridge Rindge Latin School.

The older brother, who was known as Timmy, appeared to be less social. "I don't have a single American friend," Tamerlan was quoted as saying in a 2010 profile in "The Comment" magazine, published by Boston University's School of Communications. "I don't understand them."

Luis Vasquez, a 25-year-old youth counselor who went to school with Tamerlan and lives two blocks away from the Tsarnaev house, remembers him differently. "He was just a big friendly giant," Vasquez said. "He had a sense of humor."

Tamerlan had a wife, Katherine Russell, and a young daughter. His aunt said he was "very happy" about his child.

"We cannot begin to comprehend how this horrible tragedy occurred," the Russell family said in a statement. "In the aftermath of the Patriot's Day horror, we know that we never really knew Tamerlan Tsarnaev."

Tamerlan had been a part-time accounting student at Bunker Hill Community College in Boston. He was enrolled there for three semesters - fall 2006, spring 2007 and fall 2008.

After winning a Golden Gloves amateur（5） boxing competition in nearby Lowell, Massachusetts, in 2004, Tamerlan told the local newspaper, "I like the USA. ... America has a lot of jobs. "That's something Russia doesn't have. You have a chance to make money here if you are willing to work."

Tamerlan was quoted in "The Comment" magazine as saying he wanted to participate in the Olympics and would "rather compete for the U.S. than Russia" if he could not represent an independent Chechnya.

He neither smoked nor drank, and said "God said no alcohol," according to the magazine's profile of the amateur boxer.

Those who knew the younger brother painted a picture of a youth who bore none of the telltales of an immigrant: Dzhokhar had virtually no accent. He dressed in sweatshirt. He did not hang with anybody in the school's Muslim circle.

The brothers' public high school, Cambridge Rindge and Latin, is one of the most diverse in the country, its student body ranging from the children of immigrants to those of Harvard professors.

"I always sympathized with him because he was, I'd say, a kid that just really wanted to be accepted," said Taylor Conlin, who played on the Rindge lacrosse team with Dzhokhar.

Former classmates were astonished to hear that "sweet, considerate" Dzhokhar, who later enrolled at the University of Massachusetts at Dartmouth, could have been involved in the explosions.

"He was the typical Rindge kid to us, actually a lot nicer than we were, and quieter," said Mann. "But obviously he had secrets."（Reuters）
