Tamerlan is now dead, killed in a shootout with police. Police said Friday night they had taken Dzhokhar into custody after he was
cornered in a boat stored in a back yard in Watertown, Mass., after a
. Hidden behind the lives they had been leading in Massachusetts is a biography containing old resentments that appear to have mutated into radical Islamic violence.
The brothers who are alleged to have planted bombs near the finish line of the Boston Marathon on Monday reached the United States in 2002 after their ethnic Chechen family fled the Caucasus. They had been living in the Central Asian republic of Kyrgyzstan and were prevented from resettling in war-racked Chechnya.
In speaking about his boxing career in 2009, Tamerlan told a photographer that in the absence of an independent Chechnya he would rather compete for the United States than for Russia, a hint that past troubles were not forgotten. He appeared increasingly drawn to radical Islam. On a YouTube channel, he recently shared videos of lectures from a radical Islamic cleric; in one, voices can be heard singing in Arabic as bombs explode.
“My son Tamerlan got involved in religious politics five years ago,” his mother, Zubeidat K. Tsarnaeva, told Russia Today television in an interview from Dagestan, the Russian republic bordering Chechnya where she and her husband live. “He started following his own religious aspects. He never, never told me he would be on the side of jihad.”
FBI officials confirmed Friday that they questioned Tamerlan in 2011 at the request of the Russian government about possible connections to Chechen extremists. He was interviewed by the FBI in Boston, and the investigation found “no derogatory information.”
His younger brother, who was widely known as “Jahar,” may have followed in his footsteps. “He talked about his brother in good ways,” said Pamala Rolon, who was the residential adviser in the dorm where Dzhokhar lived at the University of Massachusetts at Dartmouth. “I could tell he looked up to his brother.”
Although terrorists from the Caucasus have struck in Moscow and other parts of Russia, the conflict in the region has never led to attacks in other countries. One possible explanation for the Boston bombings, said Aslan Doukaev, an expert on the Caucasus who works for Radio Liberty in Prague, is that the brothers were motivated by radical jihadism, not Chechen separatism.
As the war in Chechnya wound down after Russian forces withdrew — they left formally in 2009 — violence has spilled into neighboring republics such as Dagestan, where the Tsarnaev family once found shelter and where the brothers’ parents now live. That conflict is increasingly marked by radical Islamic terrorism in an often vicious cycle of attack and reprisal between insurgents and Russian security forces. Tamerlan visited Dagestan last year, according to an official with knowledge of his travels.
