Three men charged in connection with Boston bombing case
Three men who attended college with the Boston Marathon suspect have been charged in connection with the case.
Azamat Tazhayakov and Dias Kadyrbayev are charged with conspiring to obstruct justice. A third man, Robel Phillipos, is charged with making false statements to federal investigators.
An FBI affidavit says the three men removed bombing suspect Dzhokhar Tsarnaev's backpack from his dorm room at the University of Massachusetts at Dartmouth three days after the bombing.
The affidavit says Tazhayakov and Kadyrbayev agreed to get rid of it after concluding from news reports that Tsarnaev was one of the bombers.
A court appearance for the three is scheduled for Wednesday afternoon.
The Boston Globe reports that two of the men are from Kazakhstan, and were students at the University of Massachusetts at Dartmouth. That's where the younger Tsarnaev brother was enrolled. It's believed all three of the new suspects had some sort of connection to Dzhokhar Tsarnaev.
Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line.
Both are Russian natives who lived for several years in the U.S. They are accused of using a weapon of mass destruction.
Meantime, James Clapper, the Director of National Intelligence, has ordered a review of how information related to the Tsarnaevs was handled in the months before the attacks.
The review will look into how the FBI and other agencies developed and shared information.
"We want to see is there in fact additional protocols and procedures that could be put in place that would further improve and enhance our ability to detect a potential attack," said Clapper.
Among the questions: Could agencies have done more to look into the background of Tamerlan Tsarnaev after the Russians told the FBI and CIA two years ago that he and his mother were becoming radicalized?
Could more follow-up have been done after he returned to the US from his trip to Russia and Dagestan last year?
As investigators await results on the analysis of DNA found on bomb parts, agents overseas are exploring Tamerlan Tsarnaev's possible contacts with a Canadian boxer, William Plotnikov, who went to Dagestan in 2010 and was killed by Russian security forces last July.
Plotnikov's father, Vitaly, says his son's radicalization happened quickly:
"Always he has a lot of friends, girlfriends. Suddenly, finished. No friends, no father, no mother. Only this room and pray. That's it."
