The “Mattapan Massacre” Murder Trial, Part 1

The “Mattapan Massacre” Murder Trial, Part 1

Dr. Edward Schwartz was the jury consultant who worked on behalf of Dwayne Moore’s defense team in the “Mattapan Massacre” murder retrial. In this interview, Dr. Schwartz discusses his role in the case,  the intense media coverage surrounding the trials, and the twelve Worcester County jurors who decided the defendant’s fate.  During the interview, Dr. Schwartz posed an interesting question: Did the December 14, 2012 shootings at Sandy Hook Elementary School in Newtown, Connecticut have any impact on juror deliberations in the Moore case?


On September 25, 2010, three adults and one small child were gunned down on Woolson Street in the Mattapan section of Boston, Massachusetts. A fifth victim survived the shooting but was left paralyzed. The shootings followed a drug-related home invasion and robbery.  This tragic event shocked the Boston community and became known as the “Mattapan Massacre”.

Dwayne Moore  was one of three suspects accused of participating in the crimes.  Dwayne Moore provided conflicting statements to the police.  Moore told the police that he was at home at the time of the robbery. He later told law enforcement officials that he fled the scene before the murders, but heard the shots from afar.  Moore was charged with multiple crimes which included four counts of murder.

Moore’s first trial ended with a hung jury. However, Dwayne Moore was ultimately found guilty on December 17, 2012 following a retrial.  Moore received four mandatory life sentences for the murders.
