A new lawyer for the widow of Boston Marathon bombing suspect Tamerlan Tsarnaev says his client will continue to cooperate with investigators. New York criminal defense lawyer Joshua Dratel has represented several terrorism suspects. Last week he joined the legal team for Katherine Russell, who lived with Tsarnaev in Cambridge, Mass., but has been staying with her family in North Kingstown, R.I. Dratel tells The Associated Press that Russell is in a fluid situation that's not yet at an end. Russell hasn't been charged with any wrongdoing. Her lawyers have said she had no reason to suspect her husband. But they haven't spoken publicly about what she saw in the days surrounding the deadly April 15 bombing. Dratel said Tuesday it would be counterproductive to speak about the details while the investigation continues.
