MONTREAL -- It is Day 6 of deliberations for jurors in the Montreal trial of Luka Rocco Magnotta.

Magnotta is charged with first-degree murder and four other offences in the slaying and dismemberment of Chinese engineering student Jun Lin in May 2012.

Jurors officially started working at about 9 a.m. today as they try to reach unanimous verdicts on all five charges.

The eight women and four men deciding his fate began deliberations on Tuesday and have since contacted the court only twice -- once to ask a legal question and once to get technical help.

Magnotta has pleaded not guilty by way of mental disorder and is trying to be found not criminally responsible.

His lawyer says he is schizophrenic and couldn't tell right from wrong at the time of the slaying, but prosecutors say Lin's death was planned and deliberate.

In addition to the murder charge, Magnotta is also accused of 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.
