BOSTON -- A federal judge has ruled that three friends of the Boston Marathon bombing suspect will be tried separately.
But the judge also says it is unnecessary to move the trials out of Massachusetts.
The judge ruled Tuesday that Azamat Tazhayakov will stand trial on June 30, followed by Dias Kadyrbayev on Sept. 8, and Robel Phillipos on Sept. 29.
Tazhayakov and Kadyrbayev are both from Kazakhstan and are in the U.S. on student visas. They face charges of tampering with evidence for removing Dzhokhar Tsarnaev's laptop and a backpack of fireworks from his University of Massachusetts Dartmouth dorm room.
Phillipos is charged with lying to investigators.
They have pleaded not guilty.
The April 2013 marathon attack killed three and injured more than 260.
