FBI seek to speak to bomb suspect's wife

Federal authorities have asked to speak to the wife of Boston Marathon bomb suspect Tamerlan Tsarnaev, a young American woman from a comfortable middle-class background who converted to Islam after she met him.

Her lawyer Amato DeLuca said his client did not suspect her husband of anything, but had not seen much of him in recent days as she was working long hours while he cared for their toddler daughter.
