Six months after a jury deadlocked on charges against Dwayne Moore, accused of the 2010 quadruple murders in Mattapan, prosecutors unveiled a new strategy: They will present taped police interviews with Moore that they believe show he had the means and motive to carry out one of the worst killings in Boston’s recent history.

To counter, Moore’s defense will apparently suggest that any new evidence and testimony presented in the trial would be merely a poor attempt to strengthen a case with a weak foundation.
