Closing Arguments Presented In Retrial Of Mattapan Murders Suspect

Attorneys presented their closing arguments Tuesday in the retrial of the man charged with killing three adults and a toddler in Mattapan two years ago.

This is the second time prosecutors have laid out a case against Dwayne Moore. An earlier trial ended with a hung jury.

During closing arguments, Assistant District Attorney Edmond Zabin told this jury there's no doubt Moore is responsible.

"We know that Dwayne Moore had motive, we know that he had knowledge, we know that he had opportunity," Zabin said. "He knew what was going on at 23 Sutton St. He knew about the drugs, he knew about the money."

But the defense is asking jurors to decide whether witnesses in the trial are believable. The prosecution's key witness, Kimani Washington, testified as part of a plea deal. Washington admits to going to a house to commit a drug robbery, but says he left before anyone was shot.

"There's not one shred of evidence linking Dwayne Moore up to these crimes," defense attorney John Amibile said. "They find 107 usable, latent finger prints, there isn't one print that matches Dwayne Moore on anything. Nothing."

The jury will receive instructions from the judge Wednesday morning before beginning its deliberations.
