Former suspect in Mattapan quadruple murder testifies

BOSTON (WHDH) -- A former suspect in the Mattapan quadruple murder case testified on Tuesday. The man took a plea deal in exchange for testimony.

The former suspect pointed out two people in the courtroom on Tuesday and said that one of them admitted to murdering four people in Mattapan, including a 2-year-old boy, in 2010.

“I know he said he had to go back, and he killed everybody,” said Kimani Washington, former murder suspect.

Kimani Washington, 36, said Dwayne Moore, 34, admitted to murdering four people in the massacre. Washington, the prosecution’s star witness, cut a deal in exchange for testifying against Moore, and against Washington’s cousin, Edward Washington.

The two men are accused of murdering four people, including 2-year-old Amanihotep Smith who was killed along with his mother.

Kimani Washington said he and the two defendants robbed a home in Mattapan of money and drugs, and when he left by himself, the occupants at the home were still alive. Washington said after the robbery, he met up with the other two later. But after getting questioned by a police officer, Kimani Washington said he confronted Dwayne Moore the next day, and that Moore admitted to the killing.

“Told him that I got pulled over by the police that morning. I said to him, ‘The police told me that the kid got shot, the baby,’ I asked, I said, ‘Dwayne, did you shoot the kid, man?’ He said, ‘No. I shot the girl and the way she was holding the baby, the baby must have got shot,’” Kimani Washington said.

Kimani Washington will return to the stand on Wednesday. The defense has indicated that it will try to paint him as a liar who is just trying to save his own skin.
