Luka Rocco Magnotta, a former adult film actor, is alleged to have brutally killed a man in Montreal and shipped at least two body parts to political parties in Canada.
He is now the subject of an international manhunt.
Thursday morning, INTERPOL issued an international arrest warrant for Magnotta, who may have fled overseas, with France as one possible destination.
He is still at large as of this report.
The global bulletin follows a Canada-wide warrant issued by Montreal police hours after officers first entered the 29-year-old suspect's blood-soaked apartment.
It was the scene of one of the most gruesome killings in Montreal in recent memory. Investigators found a torso left in a suitcase, while a hand and foot were mailed to the Ottawa offices of the Liberal and Conservative parties.
Police have obtained a video allegedly depicting the crime, and are taking steps to have it removed from a website where it was posted.
As authorities search for Magnotta, the young man's past has come under the microscope and Canadians are trying to come to terms with what kind of person might have committed such gruesome acts. Who is Luka Rocco Magnotta?
According to a neighbor, Magnotta moved to Montreal four months ago.
Magnotta is a self-described male model who launched his bisexual porn acting career "doing webcam shows" in Los Angeles when he was 20 years old.
Photographs of him - often shirtless, his lips rouged and set in a model pout - are all over the Internet. Magnotta is featured in a number of online interviews about the porn industry and has often professed his love for cosmetic surgery.
According to the Montreal Gazette, animal-rights activists worldwide have been after Magnotta since 2010, after a video surfaced that allegedly showed him placing two kittens in a plastic bag and then vacuuming the air out, suffocating them.
Two more videos, also depicting the torture and killing of cats, also have been linked to Magnotta. A $5,000 reward was offered to bring him to justice.
Police say Magnotta was romantically linked to Karla Homolka, the former wife of convicted killer Paul Bernado. Homolka was convicted of manslaughter in the 1991-92 rape-murders of three young women, including Karla's sister Tammy Homolka.
