FBI Look for Others Related to Boston Bombing

TEMPO.CO, Boston – The Federal Bureau of Investigation (FBI) still has to other person of interest that may have ties to the Boston Marathon bombing incident. "We are looking at phone calls before and after the bombing," said Congress member Dutch Ruppersberger to ABC News on Sunday.

Similar statement was made by Congressman Mike Rogers, the Republican chairman of the House Of Representatives intelligence committee. "We still have persons of interest that we're working to find, identify and interrogate," said Rogers.

Homeland Security Chairman Michael McCaul said to Fox News that they are assessing whether the two bombers were trained in constructing and exploding the bomb.

"Given the level of sophistication of the bomb, the fact that the pressure cooker is a signature device that goes back to Pakistan, Afghanistan, leads me to believe that they have a trainer and the question is where is that trainer or trainers," said Michael McCaul.

Two brothers, Dzokhar and Tamerlan Tsarnaev, are suspected to be responsible for the Boston Marathon bombing. Tamerlan was killed when police tried to arrest him, while Dzokhar is now detained, after found dying in a boat. The Police is currently investigating the motive behind the bombing.
