(NECN: John Moroney) - Jury deliberations started all over again Monday in the Mattapan Massacre retrial of Dwayne Moore.
A judge dismissed one juror and replaced him with an alternate Monday morning.
Judge Jeffrey Locke dismissed a juror in the Mattapan murder trial after deciding the male panel member had been doing independent online research about the case.
Locke said he was notified of the problem in a note from the foreperson on behalf of the entire jury.
The juror is said to have looked into technical issues related to ballistics and then talked about his findings with other jury members.
The foreperson first told a court officer about the development Friday, the day deliberations were suspended because one of the jurors was sick.
The jury of six men and six women has been considering the fate of 35-year-old Dwayne Moore since last week.
Moore is accused of killing four people and paralyzing another during the 2010 shootings.
Locke spoke with each of the remaining jurors one-on-one before seating an alternate.
"It's a testament to the jurors who obey their oath. That many of them immediately and forcefully chastised the juror who had done research," said Locke.
