Justice David Gates will determine whether to impose a sentence on Garland that would prevent his seeking parole for 75 years.
Five victim impact statements are expected to be read during the hearing, but there is no information on who will be speaking.
It could mean that Garland would stay in jail without any chance of parole for 75 years, matching the stiffest sentence handed down in Canadian history. After a short deliberation, 10 of the 12 jurors made that recommendation. Bourque pleaded guilty to three counts of first-degree murder in the deaths of three Mounties and the attempted murder of two other RCMP officers in Moncton, N.B., in 2014.
Garland will also have an opportunity to address the court if he wishes.
"I bet you that he is pouring over law books and pouring over precedent as we speak", said King.
The Crown argued there was enough evidence to show Garland attacked the three in the home before taking them to his farm where he killed them, but the defence said there was no DNA evidence to prove he was ever in the house. There was evidence presented at trial that Garland burned the bodies.
But he says they need to avoid speculating what might have happened to the three on June 30, 2014.
The search for Nathan and his grandparents ended two weeks after their disappearance when Garland was arrested and charged with murder.
