Suffolk County District Attorney Daniel F. Conley today delivered the following statements on verdicts today in the quadruple murder trial of DWAYNE MOORE (D.O.B. 6/25/77) of Mattapan and EDWARD WASHINGTON (D.O.B. 3/28/79) of Dorchester:

“I want to make clear from the outset that we have every intention of holding Dwayne Moore accountable. Today’s mistrial does not change our position that he pulled the trigger on five human beings, killing four and paralyzing one. We are steadfast in the decision to continue moving forward against him. These crimes demand justice and the evidence supports a conviction.

“We knew from the outset that the case against Edward Washington was the more difficult to prove. It always is when the charge is felony murder and the theory is joint culpability. We believe the evidence supported his conviction, but the jury has spoken and we respect its decision.

“We don’t know what transpired in the jury room. We caught glimpses through the foreman’s notes but we’re not in a position to comment on deliberations.

“There’s a great deal more we’d like to say. But our determination to prosecute Dwayne Moore to a conviction on each of the remaining nine counts means we have to refrain from saying anything that could jeopardize a future trial. In the meantime, our thoughts and prayers now are, as they’ve been since that terrible morning, with the families and loved ones of those whose lives were lost.”

On their seventh cumulative day of deliberations, jurors acquitted Washington of four counts of first-degree murder for the shooting deaths of Sept. 28, 2010, shooting deaths of Levaughn Washum-Garrison, Simba Martin, Eyanna Flonory, and her son, Amanihotep Smith, on Woolson Street in Mattapan. Jurors also acquitted him of aggravated assault and battery with a dangerous weapon and armed assault with intent to murder for the near-fatal shooting of another man, which left him paralyzed from the shoulders down, and additional counts of armed robbery, armed home invasion, and unlawful possession of a firearm.

Jurors deadlocked on identical charges against Moore, acquitting him of a single count of trafficking in more than 28 grams of a Class B substance. His case will return to court next week, when a new trial date is expected to be scheduled.

Kara Hayes and Michael Schultz were the DA’s victim-witness advocates on the case. Judge Christine McEvoy presided over the trial.
