A friend of alleged Boston Marathon bombing suspect Dzhokhar Tsarnaev was convicted of obstruction of justice and conspiracy for trying to cover up evidence that could have incriminated his college friend.

Twenty-year-old Azamat Tazhayakov is one of three of Tsarnaev's friends at the University of Massachusetts Dartmouth who was accused of interfering with the bombing investigation days after the attack on April 15, 2013. He was the first former UMass Dartmouth student to stand trial. The other two former students, Dias Kadyrbayev and Robel Phillipos, are set to face an obstruction of justice trial later on this year.

On Monday, Tazhayakov was found guilty of going to Tsarnaev's dorm room on April 18 and removing the suspected bomber's backpack, which prosecutors say contained manipulated fireworks, reports the New York Times.

Tazhayakov, who faces up to 20 years in prison, is due back in court Oct. 16 for his sentencing trail, said the office of Carmen Ortiz, the U.S. Attorney for Massachusetts, according to the Washington Post.

Kadyrbayev will face the same charges as Tazhayakov and is scheduled to appear before the same judge in September, according to the U.S. District Court for Massachusetts. Meanwhile, Phillipos is accused of lying to investigators about his whereabouts that night and will stand trial later that month.

Tsarnaev's trial is set for November. If convicted, he could face the death penalty.

During Tazhayakov's trial, he revealed that the suspected bomber remained calm and normal after he allegedly planted two bombs at the marathon's finish line. According to Tazhayakov, Tsarnaev sent him a text message about an hour after the homemade bombs exploded, which read: "Don't go thinking it's me, you cooked bastard," reports the Boston Globe.

Prosecutors portrayed him and Kadyrbayev as party-loving students who opted to protect their close friend rather than help law enforcement identify and stop the suspects even days after police announced that Tsarnaev was a suspect in the case.
