Luka Magnotta was a ‘man on a mission’ when he dismembered Lin Jun

A Canadian man accused of dismembering his Chinese lover and mailing the body parts to schools and political parties around the country kept a promise made several months earlier to take the life of a human being, the prosecutor said in his closing arguments.

Louis Bouthillier asked jurors on Thursday to convict Luka Magnotta of first-degree murder and four other charges in the 2012 slaying of Lin Jun. The jury is expected to begin deliberations next week.

The gruesome case shocked Canadians and quickly gained international notoriety after body parts arrived at offices of Canada’s biggest political parties and a video appeared online that prosecutors say shows Magnotta stabbing and having sex with the dismembered corpse.

Magnotta, 32, has pleaded not guilty and while he admits to the slaying, he is seeking to be found not criminally responsible by way of mental disorder.

Other charges include committing an indignity to a body; publishing obscene material; criminally harassing Prime Minister Stephen Harper and other members of Parliament; and mailing obscene and indecent material.

In May 2012, a package containing a severed foot was found at the headquarters of Canada’s ruling Conservative Party. That same day, a hand was discovered at a postal facility, in a package addressed to the Liberal Party of Canada.
