Kimani Washington was sentenced today for his part in the armed robbery that took place before four adults and a toddler were taken outside and shot to death, four of them fatally, on Sept. 28, 2010, the Suffolk County District Attorney's office reports.
Washington's sentencing came after he pleaded guilty to charges of home invasion, armed robbery, armed carjacking, unlawful possession of a firearm, trafficking in a Class B substance, and possession of a Class D substance. The DA's office says Washington, who was facing two assault-and-battery charges at the time, left Woolson Street before the massacre.
Washington  was a key prosecution witness in the case against Dwayne Moore , who convicted of first-degree murder last month . He also testified against his cousin, Edward Washington, who was acquitted on murder charges  last March.
