Boston Marathon bomber's friend faces sentencing for taking backpack, computer from dorm room

A college friend of Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) faces up to seven years in prison when he's sentenced for impeding the bombing investigation.

A sentencing hearing is scheduled Tuesday for Dias Kadyrbayev (DY'-us kah-dur-BY'-ehv). He pleaded guilty last year to obstruction of justice and conspiracy charges for removing items from Tsarnaev's dorm room after recognizing his friend in photos released by the FBI days after the bombing.

Prosecutors say Kadyrbayev exchanged text messages with Tsarnaev, then went to his room with two other friends. There, he and another man agreed to remove Tsarnaev's computer and a backpack containing fireworks that had been partially emptied of their explosive powder. Kadyrbayev also threw the backpack into a garbage dumpster.

Three people were killed and more than 260 were injured in the 2013 bombing.
