The two sisters of Katherine Russell – the North Kingstown widow of accused Boston Marathon bomber Tamerlan Tsarnaev – testified before a federal grand jury Thursday, according to the Associated Press.
Providence lawyer Amato DeLuca, who represents Russell and her family, said Anna and Rebecca Russell testified at the federal courthouse in Boston. Their parents, Judith and Warren Russell, testified before the grand jury in September. Katherine has not been called.
On April 15, 2013, three people were killed and more than 260 people wounded when two bombs were detonated at the finish line of the Boston Marathon. Tamerlan and his brother, Dzhokhar, were implicated after they were identified in photos taken at the scene. Tamerlan was killed April 19 during a firefight with police in Watertown. Dzhokhar was captured later that same date, hiding in a boat in a Watertown backyard.
Russell has been questioned several times by federal investigators; she has not been charged with any wrongdoing.
She, her husband and their 3-year-old daughter lived in an apartment in Cambridge before and after the bombings. After her husband was killed, she and their daughter moved to her parents' home in North Kingstown, where she grew up.
