Attorneys for accused Boston Marathon bomber Dzhokhar Tsarnaev made their case for moving his trial to Washington this week, citing “an extraordinarily high” level of pretrial publicity in Boston and support there for the death penalty.

In a motion filed on Thursday, they cited expert testimony by Edward Bronson, a professor emeritus of political science at California State University, Chico, that “an overwhelming presumption of guilt and prejudgment as to the penalty exists in the District of Massachusetts.”
