Tsarnaev college friend gets 6-year prison term

BOSTON — Dias Kadyrbayev, a college friend of Boston Marathon bomber Dzhokhar Tsarnaev, was sentenced Tuesday to six years in prison.

Kadyrbayev, 21, pleaded guilty last year to obstruction of justice and conspiracy charges for removing items from Tsarnaev’s dorm room.

Meanwhile, a district attorney said it’s “highly likely” that police Officer Richard Donohue who was critically injured in a gunbattle with the bombers was struck by friendly fire.
