The fate of a B.C. couple accused of plotting a 2013 Canada Day attack at the B.C. legislature is now in the hands of a B.C. Supreme Court jury nearly four months after the trial began.

The jury began its deliberations at 9:30 a.m. PT Sunday.

It took Justice Catherine Bruce three days to deliver her instructions in the complex legal case, reading from a summary of facts more than 300 pages long.

It's a process that clearly wore on many of the jurors, who by midday Saturday were nodding off or yawning in their seats as the judge went through her instructions page-by-page.

During the trial, more than 100 hours of audio and video evidence, captured by undercover RCMP officers in an elaborate sting operation, were presented to the court.

The officers posed as terrorists and befriended the couple in the months leading up to the alleged plot to attack the legislature in Victoria using pressure cooker bombs like the ones used in the Boston Marathon bombing.

Defence says pair were manipulated

Lawyers for Korody and Nuttall argued RCMP officers manipulated the pair. They maintained their plan to detonate the bombs at the legislature would not have materialized had they not been pushed by police.

They described the couple as former heroin addicts with money issues who were given a purpose when befriended by RCMP officers, who gave them money, clothes and spiritual guidance.

The Crown argued the couple planned to kill innocent people and were fully aware of what they were doing.

Nuttall and Korody are accused of conspiracy to commit murder, making or possessing an explosive device, conspiracy to place an explosive device with the intent to cause death or injury, and conspiracy to murder persons unknown.

Earlier this month, Justice Bruce told the jury that due to legal reasons they would not be required to make a decision on count three of the indictment — facilitating a terrorist act.

Nuttall and Korody have pleaded not guilty.
