The trial of a Canadian man accused of dismembering his Chinese lover and mailing the body parts to schools and political parties is underway.

Luka Magnotta, who faces five charges in connection with the 2012 slaying of engineering student Jun Lin, appeared before a judge and jury Monday.

Magnotta, wearing a grey sweater, dark pants and dark-rimmed glasses, pleaded not guilty again to all charges as he stood behind a metal-and-glass enclosure.

He is facing a murder charge and four others: 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.

He is accused of posting a video online that shows him stabbing and having sex with the dismembered corpse.
