Two Friends of Boston Bomber to Be Sentenced for Hampering Probe

Two friends of convicted Boston Marathon bomber Dzhokhar Tsarnaev will learn on Friday how long they will spend in prison for having removed a backpack containing fireworks from the suspect's room during a massive manhunt. Kazakh exchange student Azamat Tazhayakov and Robel Phillipos, of Cambridge, Massachusetts, joined a third friend and fellow student in going to Tsarnaev's dorm room three days after the April 2013 bombing, after the FBI released images of Tsarnaev and his older brother, Tamerlan, identifying them as suspects. The third friend, Dias Kadyrbayev, also of Kazakhstan, was sentenced on Tuesday to six years in prison after pleading guilty to obstructing the investigation into the attack that killed three people and injured 264.
