Luka Rocco Magnotta, a man with a disturbing online presence, has been named a suspect in a horrific homicide case involving the mailing of body parts to Canadian politicians. The Canadian police have issued a nationwide warrant for him.

On Tuesday, police officials discovered a hand and a foot mailed separately to the offices of political entities. They also found a male torso in a Montreal neighborhood near Magnotta's apartment, according to the BBC.

They now think these dismembered parts are from the body of the same murdered man. Magnotta is named as the suspect partly because of a disturbing video that purportedly shows him stabbing a naked man tied to a bedframe, slashing his throat and later decapitating him, according to the National Post.

The video, posted on a website called Best Gore, also shows the attacker performing sex acts on the victim's dismembered body parts.

The Montreal Gazette confirmed that the police have obtained a disturbing video of the crime.

On the Internet, a person using the name Luka Rocco Magnotta is featured on a number of lurid websites and is a low-budget gay porn star suspected of appearing in a number of kitten-killing videos, writes the National Post.

In 2009, Magnotta may have authored an online post on how one could disappear completely and never be found, which suggests it may be difficult for the police to find him right now, writes Stephen Maher of Postmedia News, who also notes that serial killers usually target animals before they move on to people.

In March of this year, Magnotta reportedly wrote online that he has feelings, real feelings, for dead men, according to Maher.

In 2005, Magnotta was convicted on four counts of fraud, reported CBC News. He was also rumored to be linked to Karla Homolka, a Canadian woman convicted of killing two Ontario teenage girls in the early 1990s.

Magnotta's birth name is Eric Clinton Newman; his aliases include Eric Clinton, Kirk Newman and Vladimir Romanov, according to the Montreal Gazette.
