Closing arguments at Oland's preliminary inquiry wrapped up today in Saint John, where Judge Ronald LeBlanc of the provincial court adjourned the matter until Dec. 12.
LeBlanc must decide whether there is enough evidence to send the case to trial.
Richard Oland was found dead in his Saint John office on July 7, 2011.
The 69-year-old was a prominent businessman, a member of the Order of Canada, and part of the well-known Maritime family that owns Moosehead Breweries.
He left the company in the 1980s and went on to work in the trucking business and at the Saint John Shipbuilding and Drydock Co.
Dennis Oland was arrested about a year ago and granted bail.
Saint John police Chief Bill Reid said last November that Richard Oland died after repeated blows, but he wouldn't elaborate.
The preliminary hearing lasted 37 days and heard from 42 witnesses.
A publication ban was placed on the evidence presented at the hearing.
