(AP) — Two college friends of suspected Boston Marathon bomber Dzhokhar Tsarnaev were indicted Thursday for allegedly trying to thwart investigators by throwing away fireworks and other items they found in Tsarnaev's dorm room the day before his capture.

Authorities later discovered the fireworks in a New Bedford landfill, the federal indictment says.

Dias Kadyrbayev and Azamat Tazhayakov, both 19 and nationals of Kazakhstan, face charges of conspiracy to obstruct justice. The two, who were in the U.S. attending college and shared an apartment in New Bedford, have been detained since they were charged in a criminal complaint in May.

If convicted, they face up to 20 years in prison. Both are scheduled for arraignment Tuesday.
