MONTREAL -- Jurors deciding the fate of Luka Rocco Magnotta have completed their seventh day of deliberations without reaching any verdicts.

Since being sequestered last week, the panel of eight women and four men has contacted the court only twice -- once to ask a legal question and once to get technical help.

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.

He has pleaded not guilty by way of mental disorder in the hope of being found not criminally responsible.

The jury will be back for an eighth day of deliberations on Tuesday.

Magnotta's lawyer claims his client is schizophrenic and couldn't tell right from wrong at the time of the slaying, while prosecutors argue Lin's death was planned and deliberate.

In addition to first-degree 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.
