A suspect in 2010 Mattapan killings may get plea deal
One of the three men implicated in the 2010 killings of four people on a Mattapan street, including a toddler, has agreed to plead guilty to the charges against him and testify against his codefendants, an agreement that could help him avoid decades in prison. Kimani Washington, 36, of Dorchester, who police said stashed a gun used in one of the city’s worst killings in five years, would spend 16 to 18 years in prison under an agreement struck with Suffolk County prosecutors, according to several people with knowledge of the deal. Washington is expected to testify in Superior Court in February in the murder trials of his cousin Edward Washington, 32, and Dwayne Moore,, 34, the sources said. They spoke on condition of anonymity because of the sensitivity around the case.
