Three Newly Charged in Boston Bombing Accused of Disposing of Evidence

Allegedly helped Tsarnaevs.

Two men from Kazakhstan and a man from Cambridge were arrested and charged today in the Boston Marathon bombings investigation, federal prosecutors said.

Azamat Tazhayakov and Dias Kadyrbayev, both 19 and of New Bedford, were charged with conspiracy to obstruct justice by plotting to dispose of a laptop computer and a backpack containing fireworks belonging to bombing suspect Dzhokhar Tsarnaev, the US attorney's office said in a statement.

Robel Phillipos, 19, of Cambridge was charged with making false statements to law enforcement officials in a terrorism investigation, prosecutors said. All three were, or had been, students at the University of Massachusetts Dartmouth, where Tsarnaev, 19, was also a student.
