BOSTON (AP) -
A friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev is expected to testify at a hearing on his request to suppress statements he allegedly made to federal agents.
A linguistics expert took the stand in the evidence suppression hearing. The woman analyzed Dias Kadyrbayev's writings, saying it's unlikely he understood authorities when they read him his Miranda rights.
Kadyrbayev and another friend, Azamat Tazhayakov, are accused of removing items from Tsarnaev's dorm room at the University of Massachusetts-Dartmouth several days after the bombing, including Tsarnaev's laptop computer and a backpack containing fireworks. A third friend, Robel Phillipos, is accused of lying to investigators.
The men are not accused of participating in the bombing or knowing about it ahead of time.
Tazhayakov and Phillipos declined to testify during a suppression hearing in May. Judge Douglas Woodlock said he would not suppress their statements.
Kadyrbayev is expected to take the witness stand Monday in U.S. District Court.
