(CNN) -- A friend of accused Boston bomber Dzhokhar Tsarnaev is expected to plead guilty Thursday to charges in connection with removing a backpack and computer from Tsarnaev's dorm room after the Boston Marathon bombing.
Dias Kadyrbayev will be changing his plea in a federal courtroom Thursday, his lawyer, Robert Stahl, told CNN, adding that he'll have more to say after the hearing.
The charges stem from actions after bombs exploded near the finish line of the Boston Marathon on April 15, 2013. Three people were killed and more than 200 were injured.
Kadyrbayev is charged with four counts including obstructing justice and conspiracy for allegedly throwing Tsarnaev's backpack into a dumpster after discovering it contained fireworks with gunpowder, and removing a jar of Vaseline and a computer thumb drive. The backpack was later recovered at a landfill by investigators.
Kadrybayev, a Kazakh national, also allegedly took Tsarnaev's computer to his off-campus apartment, where the FBI later seized it.
In July, Kadyrbayev's roommate Azamat Tazhayakov was convicted of conspiracy and obstruction charges in the same case and has filed an appeal. He faces up to 25 years in prison at his sentencing in October.
In that case, prosecutors told jurors Tazhayakov knew the identity of the suspected bombers -- Tsarnaev and his older brother Tamerlan Tsarnaev -- before the public found out, allegedly texting Kadyrbayev: "i think they got his brother," hours before the public knew their names or their relationship to one another.
The friends recognized the Tsarnaev brothers after authorities released video and still photos asking for the public's helping finding the two men in the aftermath of the bombings, prosecutors said. Kadyrbayev told his friends that he believed Dzhokhar Tsarnaev "used the Vaseline 'to make bombs,' or words to that effect," an indictment against him reads.
The government said Tsarnaev texted Kadyrbayev after the bombings and told him he could go to his dorm room and take what he wanted. Kadyrbayev showed that text to Tazhayakov, the government alleged.
