Dwayne Moore, 33, of Mattapan, was arrested today for the Sept. 28 murders of three adults and one child on Woolson Street in Mattapan, Boston Police and the Suffolk County District Attorney's office announced.
Moore was charged with killing Levaughn Washum-Garrison, Simba Martin and Eyanna Flonory and her 2-year-old son Amanihotep Smith on Sept. 28.
Police and prosecutors said they could not comment further because a Suffolk County grand jury is currently investigating the crimes.
Dwayne Moore was convicted of manslaughter in 1996 for killing a Milton teen in a fight on Arborcrest Terrace in Mattapan the year before. According to a Massachusetts Appeals Court ruling:
The defendant [Moore] then pushed the victim and the two fought in front of Barlatier's house. While they were wrestling, the victim took out a knife. The defendant grabbed the hand in which the victim held the knife. The victim then fell to the ground where the defendant and another individual, Fillmore Parris, repeatedly punched and kicked the victim. Barlatier tried to stop the fight by grabbing the defendant, but the defendant continued the beating. Barlatier noticed that the defendant was bleeding from his back.
The victim got up and ran toward a fence. He tried to climb over the fence but the defendant pulled him back down. The defendant then grabbed the knife out of the victim's hand and stabbed the victim in the area of the neck, either once or twice. While the victim was on the ground, the defendant and Parris again repeatedly kicked him. The defendant left the scene and Barlatier, who was looking for the victim, found the defendant about two streets away. The defendant then ran off when he saw a police cruiser approaching.
Moore was sentenced to 16 to 18 years in state prison.
Moore is the second person arrested in connection with the Woolson Street murders. Last month, police arrested Kimani Washington on charges of illegal possession of a firearm and receiving stolen property.
