The 1st U.S. Circuit Court of Appeals in Boston has overturned the death sentence of 2013 Boston Marathon bomber Dzhokhar Tsarnaev. His conviction has been upheld and a new trial is set to determine a different sentence.
Tsarnaev and his brother, Tamerlan, planted two bombs near the finish line of the Boston Marathon, which killed three people and injured more than 260 others. His brother was killed in a shootout with police on April 19, 2013.
In 2015, Tsarnaev was convicted and sentenced to death on 30 charges, including conspiracy and use of a weapon of mass destruction.
