Lawyers for Katherine say she is doing everything she can to assist authorities but they wouldn't say Tuesday if she has spoken to investigators yet.
Providence attorneys Amato DeLuca and Miriam Weizenbaum issued a statement Tuesday saying Tsnarnaeva is deeply mourning the bombing victims. They say that Tsarnaeva and her family were in shock when they learned of allegations against her husband and brother-in-law, Dzhokhar Tsarnaev.
The lawyers say Tsarnaeva, whose toddler is the daughter of the late suspect, is "trying to come to terms with these events."
DeLuca told the Associated Press on Sunday that federal investigators want to speak with his client. They wouldn't comment Tuesday beyond the statement.Katherine stayed in the couple's Cambridge apartment last year while Tamerlan traveled to Russia for about six months. His aunt told The Associated Press that he spoke with Katherine every day on Skype and that at times she would instruct him on correct religious practices.
