The investigation into the Boston Marathon bombings now turns to motive, after the 19-year-old second suspect was captured Friday night. Police are still unsure whether the brothers acted alone.
Dzhokhar Tsarnaev is in serious condition at Beth Israel Deaconess Medical Center in Boston, after being captured yesterday in Watertown, Mass.
His brother Tamerlan, 26, died earlier in the day in a shootout with police.
Dzhokhar has not yet been charged and Beth Israel spokeswoman Kelly Lawman said the FBI would provide updates on his condition.
The Boston Marathon bombings killed 3 people and injured 176 in what President Obama has called the worst attack on U.S. soil since 9/11.
The FBI said on Friday that Tamerlan had been interviewed in 2011 at the request of a foreign government, which was not identified.
"The request stated that it was based on information that he was a follower of radical Islam and a strong believer, and that he had changed drastically since 2010 as he prepared to leave the United States for travel to the country's region to join unspecified underground groups," the FBI said in a statement.
The matter was resolved when the FBI "did not find any terrorism activity, domestic or foreign." One official said the FBI’s findings were shared with the foreign country.
Two young men and a woman believed to be affiliated with Tamerlan were detained in New Bedford on Friday. No word on whether they have been charged in connection with the bombings.
The brothers spent their early lives in a small Chechen community in Kyrgyzstan, a nation with 5.5 million Muslims. In 2001, the family moved to Dagestan in southern Russia. Their father is currently living there. His CNN interview on Friday was cut short when Russian police showed up to interrogate him.
The two boys moved to the U.S. in 2002 and lived for a time with their uncle, Ruslan Tsarni, who adamantly condemned the bombings.
Their father, Anzor Tsarnev, claimed his sons are innocent and were framed by police.
In 2001, Anzor Tsarnev was also interviewed by the FBI for taking photographs of the Manhattan skylane after the 9/11 attacks.
The boys’ mother, Zubeidat, who currently lives in Russia, also believes her sons were “set-up.” She made a bizarre statement that Tamerlan “was controlled by the FBI … for three to five years.”
Zubeidat was reportedly arrested in 2012 for stealing and damaging goods at a Lord & Taylor department store in Natick, Mass.
The boys’ uncle Ruslan Tsarni, who lives in Washington D.C., claimed the oldest boy was “radicalized” and used his younger brother. He told the press on Friday that the boys had difficulty adjusting to living in the United States and eventually ended up “just hating everyone.”
In an essay on his love of boxing, Tamerlan wrote "I don't have a single American friend.” However Tamerlane did have an American wife who converted to Islam. 24-year-old Katherine Russell has a 3-year-old daughter with Tamerlan named Zahara.
Russell’s parents, Judith and Warren, said “In the aftermath of the Patriot's Day horror, we know that we never really knew Tamerlan Tsarnaev. Our hearts are sickened by the knowledge of the horror he has inflicted."
