A Superior Court judge says a jury must be brought in from Worcester to ensure a fair retrial for Dwayne Moore, who faces charges that he killed four people in Mattapan in 2010.

Judge Jeffrey Locke says he’s making the move because of the “extensive and sensational” media coverage of the previous trial, which ended in a hung jury in the case of Moore.

“I do not find the pretrial publicity here is such that a change of venue is mandated because of presumptive prejudice so ‘utterly corrupting(ing)’ a jury ... that the defendant can only get a fair trial through a change in venue. Rather, I find that the circumstances surrounding the retrial are appropriate for at least a partial change in venue in the exercise of my discretion,” Judge Locke wrote in a decision released today.

The retrial is slated to begin next week.
