Jury deadlock in 'Mattapan Massacre' case BOSTON, March 20 (UPI) -- A Boston jury reached a verdict on only 10 of 19 charges in the "Mattapan Massacre" murder trial, and was ordered Tuesday to resume deliberations. The order to attempt to reach a unanimous verdict on the nine remaining charges came as Suffolk Superior Court Judge Christine McEvoy addressed the jury, after the foreman told her in a written statement there is one holdout on the jury seeking "absolute certainty" and that there is "no path to meaningful dialogue," The Boston Globe reported Tuesday. Dwayne Moore and Edward Washington are accused in the robbery and killings of four people, including a 2-year-old boy, during a home invasion in search of drugs and cash in 2010. Known as the "Mattapan Massacre" for the neighborhood in which it was committed, it has been called one of the worst homicides in Boston's history, the newspaper said. Moore was the shooter and Washington the getaway driver, the prosecution contends. The verdicts on the 10 decided charges have been sealed, the District Attorney's Office said.
