The attacker's death sentence ended

A US federal court has overturned the death sentence of a Boston Marathon fan who killed three Boston Marathon fans with an improvised explosive device in 2013. The court has ordered a retrial.

A three-judge bench of the U.S. First Circuit Court of Appeals has upheld three charges against Zukhar Sarnev and commuted his death sentence to five terms. He has been ordered to stand trial again.

Sarnev's lawyers argued that they had not received a fair trial. In December, the jury was composed of people directly affected by terrorism who had already made up their minds about Sarnev.

Sarneev was arrested in 2015 and held in a federal prison in Colorado. He is accused of carrying out three bombings on April 15, 2013, when he was just 19 years old, along with his 26-year-old brother, killing two civilians and a police officer. Officers were killed.
