THE FBI has removed a computer from the US home of a sister of the Boston Marathon bombing suspects while an uncle claims the younger brother was "used" as more details of their family emerges.
Police said she was co-operating with the investigation and was "heartbroken, surprised and upset," though she told reporters she wasn't sure the accusations against her brothers were true.
The woman, identified by local police as Ailina Tsarnaeva, told Federal agents she had not been in contact with her brothers for years, according to Police Director Michael Indri.
"The main concern was to confirm that there was no contact made one way or the other, and I'm confident that the FBI has confirmed that," he said.
