FBI agents who were inside the Rhode Island home of Boston bombing suspect Tamerlan Tsarnaev's in-laws and carried away several bags. One bag reportedly contained DNA samples belonging to a woman.
Katherine Russell, Tsarnaev's widow, has been staying there.
The elder Tsarnaev was killed in a gun battle with police. His brother Dzhokhar has been charged with using a weapon of mass destruction.
Russell didn't speak as she left her attorneys' office in Providence on Monday. Attorney Amato DeLuca said she is doing everything she can to assist with the investigation.
Attorneys have said Russell and her family were in shock when they learned of the allegations against her husband and brother-in-law.
Their mother calls the allegations lies.
