(MyFoxBoston.com/AP) – An internal memo from the U.S. Attorney General is revealing new details in the case of Boston Marathon bombing suspect Dzhokhar Tsarnaev.
According to the memo obtained by FOX 25, Tsarnaev disposed of key evidence, including a remaining bomb detonator. He also destroyed his cellphones.
The memo says he and his older brother, Tamerlan Tsarnaev, made additional bombs after the marathon and persuaded others to destroy evidence as well.
Dzhokhar Tsarnaev also told FBI agents he remained committed to jihad and hoped he inspired others to engage in violent jihad, the memo said.
The memo is part of the case for implementing Tsarnaev's restrictions in prison, restrictions he now wants lifted.
Tsarnaev's lawyers compared his conditions behind bars to torture.
Tsarnaev, 20, is accused of building and planting bombs near the finish line of the April 15 marathon, killing three people and injuring more than 260. Authorities say he and his older brother, Tamerlan Tsarnaev, 26, ethnic Chechens from Russia who emigrated to the United States as children, planned and carried out the attack to retaliate against the U.S. for its involvement in Muslim countries.
Tamerlan Tsarnaev was killed four days after the marathon following a gun battle with police. Dzhokhar Tsarnaev was found wounded and hiding in a boat in a backyard in Watertown.
Dzhokhar Tsarnaev was charged in a 30-count federal indictment, including 17 charges that carry the possibility of the death penalty. He has pleaded not guilty.
