Two college friends of accused Boston Marathon bomber Dzhokhar Tsarnaev who allegedly disposed of evidence were indicted on Thursday. A third, accused of lying to the FBI, asked to waive a hearing pending plea negotiations.

Dias Kadyrbayev and Azamat Tazhayakov, both 19 and nationals of Kazakhstan, were charged by a District of Massachusetts grand jury with conspiracy to obstruct justice and obstructing justice. The two, who attended the University of Massachusetts Dartmouth with Tsarnaev, were living in New Bedford. Mass., on student visas.
