Zubeidat Tsarnaeva may stay out of American custody because the US and Russia do not have a bilateral extradition treaty, despite efforts by Moscow to negotiate one.
US investigators are interested in a trip that Tamerlan Tsarnaev, the older brother suspected in the Boston bombing, took to the North Caucasus region of Russia in 2012. They want to know whether he had contact with foreign extremist groups.
