A friend of convicted Boston Marathon bomber Dzhokhar Tsarnaev who was found guilty of obstructing a police investigation into the deadly 2013 attack has been sentenced to six years in prison.
"I am ashamed by my actions," Kazakhstan national Dias Kadyrbaev told the court before his sentence was imposed on June 2.
Kadyrbaev had pleaded guilty 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.
He had faced up to seven years in prison.
Two other friends of Tsarnaev -- Azamat Tazhayakov and Robel Phillipos -- are due to be sentenced later this week for interfering with the investigation into the bombing that killed three people and injured 264.
Tsarnaev was sentenced to death in May for the attack.
