A Kazakh friend of Dzhokhar Tsarnaev could testify for the prosecution in the death penalty case against the surviving Boston Marathon bombing suspect in January.
However, Azamat Tazhayakov's deal with the prosecutor’s office has not been finalized yet, his lawyer told the Boston Globe on October 8.
In July, Tazhayakov was convicted of obstructing justice by entering Tsarnaev's dorm room days after the attack and disposing of evidence.
Tazhayakov, whose sentence is expected on October 16, faces up to 25 years in jail.
Another friend, Dias Kadyrbaev, also a Kazakh, pleaded guilty to the same charges in August.
Tsarnaev and his older brother Tamerlan are accused of planting bombs that killed three people and wounded more than 260 at the Boston Marathon on April 15, 2013.
Tamerlan Tsarnaev was shot dead during a police manhunt.
