Dzhokhar Tsarnaev tells investigators Katherine Russell Tsarnaev was not involved in Boston Marathon attacks

Dzhokhar Tsarnaev told investigators that Katherine Russell Tsarnaev, the widow of his late older brother Tamerlan, had nothing to do with the April 15 Boston Marathon attacks, it was revealed today.

Dzhokhar Tsarnaev, 19, has made the statement to law enforcement officials looking into Katherine Russell’s possible involvement in the planning of the bombings allegedly carried out by her husband, Tamerlan Tsarnaev, and her brother-in-law, NBC News reported.

Tamerlan Tsarnaev was killed in a police gun battle on April 19. His younger brother, Dzhokhar, was captured and charged in connection to the bombings following a massive manhunt that ended when he was discovered wounded hiding inside a boat in a backyard.

Katherine Russell Tsarnaev, 24, has been under increased scrutiny ever since federal officials found radical Islamist materials on her laptop, including the al Qaeda magazine Inspire.

Investigators also found traces of explosive residue in the Cambridge, Massachusetts, home Katherine Russell had shared with her late husband and their daughter.

Katherine Russell’s defense team said in a statement that she “plans to continue to meet with investigators, part of a series of meetings over many hours where she has answered questions”.

It was also revealed Wednesday that the 24-year-old Muslim convert has hired a prominent criminal lawyer with experience defending terrorism cases.

Katherine Russell added New York lawyer Joshua Dratel to her legal team, her attorney Amato DeLuca confirmed.

Joshua Dratel has represented a number of terrorism suspects in federal courts and military commissions, including Guantanamo Bay, Cuba, detainee David Hicks, who attended an al-Qaida-linked training camp in Afghanistan.
