The wife of deceased Boston bomb suspect Tamerlan Tsarnaev and her family are "trying to come to terms" with the shock that he and his brother allegedly masterminded the attacks.
A statement read out by Miriam Weizenbaum, the lawyer for Katherine Tsarnaeva, said:
The reports of involvement by her husband and brother-in-law came as an absolute shock to them all.
As a mother, a sister, a daughter, a wife, Katie deeply mourns the pain and loss to innocent victims - students, law enforcement officers, families and our community.
In the aftermath of this tragedy, she, her daughter and her family are trying to come to terms with this event.
Among those terribly injured by the Boston marathon bombs was a dance instructor. Adrianne Haslet-Davis lost her foot in the explosion.
The mother of the two brothers suspected of carrying out the Boston bombings told ITV News they saw last year's race but are innocent.
Boston's marathon bombing suspect Dzohkhar Tsarnaev was charged with an offence that could lead to the death penalty, if he is found guilty.
