Three people have been taken into custody in connection with the Boston Marathon bombings. The three people are allegedly connected to suspect Dzhokhar Tsarnaev, and two of them are also reported to be students at the University of Massachusetts at Dartmouth, where Dzhokhar was a student. The suspects, who are said to be from Kazakhstan, allegedly helped Dzhokhar after the bombings. They are being held on immigration charges and are expected to be charged with obstruction of justice.
What do we know about these three arrests? Other new details have emerged too, such as the discovery of female DNA on the bombs. Have investigators spoken to Tamerlan Tsarnaev’s wife Katherine? What else do we know as the investigation moves forward?
