MONTREAL - Jurors deciding the fate of Luka Magnotta failed to come to a verdict in their seventh day of deliberations.
Since getting the case last Tuesday the panel of eight women and four men have 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.
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 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.
