Accused Boston Marathon bomber Dzhokhar Tsarnaev on Wednesday sought to move his trial outside of Massachusetts, provisionally recommending the District of Columbia because it has “the least prejudicial attitudes” of four possible venues.

Tsarnaev’s legal team based its motion on a preliminary assessment of public opinion polls and analysis of news coverage in the four areas. The team analyzed the Boston and Springfield divisions of the District of Massachusetts; the Southern District of New York; and the federal court in the District of Columbia.
