The conviction of a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) for impeding the investigation into the bombings has his lawyers wondering if anyone else who faces charges connected to the attack stands a chance of acquittal.

A federal jury on Monday found Azamat Tazhayakov (AZ'-maht tuh-ZAY'-uh-kahv) guilty of obstruction of justice and conspiracy for trying to protect Tsarnaev by agreeing with another friend to get rid of a backpack and disable fireworks they took from his dorm room.

One of Tazhayakov's lawyers says the verdict does not bode well for well for three other men charged with obstruction of justice or lying to investigators in connection with Tsarnaev and his brother, Tamerlan Tsarnaev, who was killed in a shootout with police days after the 2013 bombings.
