Dwayne Moore, 33, was arrested today for the Sept. 28 murders [2] 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. He received a state prison sentence of 15 to 18 years after a jury found he had taken a knife away from somebody with whom he'd been feuding, then stabbed him the neck (more details [3], from a court ruling on his unsuccessful appeal of his sentence).
Moore is the second person arrested in connection with the Woolson Street murders. Last month, police arrested Kimani Washington [4] on charges of illegal possession of a firearm and receiving stolen property.
