The jury at Luka Rocco Magnotta's first-degree murder trial has been sequestered.

Deliberations begin Tuesday at 9 a.m.

Justice Guy Cournoyer completed his final instructions late Monday and 12 jurors will now decide the fate of the 32-year-old Ontario native.

They have been sent to a Montreal hotel and can not leave until they reach a verdict on each of the five charges Magnotta faces in the slaying and dismemberment of Jun Lin in May 2012.

Magnotta has admitted to the killing but has asked the jury to find him not criminally responsible by way of mental disorder.

The Crown has argued Magnotta should be found guilty of first-degree murder and the four other charges.

The jurors have been told if they opt for a not criminally responsible verdict, it must apply to all five charges.

Fourteen jurors heard the evidence but two were sent home once the judge's instructions were completed.

Cournoyer told the jurors they must rely solely on evidence they heard at the trial, which began in late September.

Psychiatrists for the defence testified Magnotta is schizophrenic, was psychotic the night of the slaying and was unable to tell right from wrong.

"Under our law, the verdict of not criminally responsible by reasons of mental disorder is not a loose term, quite the contrary," Cournoyer told the jurors. "There are specific criteria to determine whether the defence of mental disorder is applicable."

Crown prosecutor Louis Bouthillier reiterated in his final statement the crime was planned and deliberate and that there was no evidence Magnotta was suffering from a disease of the mind.

Cournoyer told the jury that Magnotta is presumed innocent, a presumption that remains unless the Crown proves its case beyond a reasonable doubt.

That burden of proof always rests with the prosecution and never shifts, he said, adding that a mental disorder defence requires the accused to meet certain standards.

"Mr. Magnotta must prove that it is more likely than not that he suffered from a mental disorder to such an extent at the time the offences were committed that he is not criminally responsible," Cournoyer said. "This is a lower standard than proof beyond a reasonable doubt."

He also told the jurors they must not be influenced by public opinion and that they have to assess the information they have impartially and without sympathy, prejudice or fear.

In addition to premeditated murder, Magnotta is charged with criminally harassing Prime Minister Stephen Harper and other members of Parliament; mailing obscene and indecent material; committing an indignity to a body; and publishing obscene materials.

What we can now report to you:

Now that the jury has been sequestered, we can now report that throughout the trial, Luka Magnotta kept a low profile in the prisoner's box. He rarely showed emotions, and mostly kept his head down.

The minute the jury would leave the room, the accused would suddenly sit straight and show interest in what went on – so much so, that the prosecution tried to have psychiatrist Gilles Chamberland comment on this odd change of behaviour in front of the court, but that legal strategy failed.

Magnotta continued to display two different behaviours, depending on whether the jury was present or not.

In other oddball events, the jury came close to watching the movie Basic Instinct, featuring actress Sharon Stone, in the court room.

The prosecution wanted to highlight the many similarities between the fictional movie and the crime committed by Magnotta, but in the end, the judge found it too prejudicial, and denied the Crown's request.

The judge also rejected the presentation of an audition video for a TV show called Plastic Makes Perfect featuring Magnotta in 2008. The prosecution wanted to show that the man who claimed he was paranoid about being filmed, was in fact, very much at ease in front of the cameras.

The jury, however, never got to see or hear any of these matters. They've now entered their deliberation room with evidence based solely on what the judge allowed to be heard inside the court room.
