OTTAWA

A porn star linked to Karla Homolka and horrific online videos is a suspect in a grisly Montreal slaying, in which body parts were mailed to political addresses.

Porn actor Luka Rocco Magnotta, 29, is being sought on a Canada-wide warrant after a dismembered torso was found in a suitcase in Montreal and body parts mailed to Ottawa.

Magnotta has been linked in the past as having had a romantic involvement with schoolgirl sex killer Homolka.

In a grisly twist to the case, a graphic and deeply disturbing video has emerged which is purported to show the murder and dismemberment. A Montreal police source confirmed cops are in possession of a video, which also includes cannibalism, but would not say if it is the same video.

The graphic video online shows a man being stabbed to death with an ice pick and then being cut into pieces. The video was shot inside an apartment that bears a close resemblance to the unit in west-end Montreal that’s at the centre of the homicide investigation.

Magnotta also goes by the names Eric Clinton Newman and Vladimir Radulov, Montreal police said. He is white, 5-feet-10 and weighs 135 pounds. He has blue eyes and black hair.

A man by the name of Luka Magnotta is also shown in other disturbing videos and photos online feeding a kitten to a python, and drowning kittens in a bathtub.

On the subject of Homolka, the self-described male model and adult film performer, who boasts of having an addiction to cosmetic surgery, vehemently denied any romantic connection when the controversy became public six years ago.

“I want to set the record straight,” he told QMI Agency in an exclusive 2007 interview. “I not only have never dated Karla, I have never even met her.”

The body parts found in the mail in Ottawa on Tuesday are believed to be from a male whose dismembered torso was discovered tossed out with garbage in Montreal.

Montreal police Cmdr. Ian Lafreniere indicated as much Wednesday.

“All of our evidence indicates that it’s related to the homicide here,” he told reporters at police headquarters. “That’s why Montreal police are investigating, with our colleagues from Ottawa and the RCMP.

“That being said, what is missing is confirmation ... to make sure that the DNA is the same in the two cases.”

Lafreniere said the suspect and the unidentified victim knew each other.

“It wasn’t done by accident,” he said. “That’s what we know. What was the exact link, we don’t know right now.

“You will understand that there are some elements that we are keeping to ourselves. Yes, we want to be as transparent as possible, but our ultimate goal is to arrest the suspect and make sure there is a trial for the person who did a crime that I would call horrible.”

The torso was found Tuesday stuffed in a suitcase and left among a large pile of garbage outside a building in the Snowdon neighbourhood.

The caretaker of the Place Lucy building found the body on Tuesday morning after receiving complaints about a strong smell coming from a garbage pile.

The janitor said the suitcase had been there for at least a week.

While Montreal police were investigating the torso, two equally horrifying discoveries were being made in mailed packages in two separate Ottawa locations. Wednesday morning, police confirmed both packages, one containing a severed human foot, the other a human hand, had originated in the Montreal area.

The severed foot was found Tuesday morning at the 130 Albert St. headquarters of the Conservative Party of Canada. A CPC staffer made the gruesome discovery after partially opening a box in the day’s mail delivery.

The staffer was overwhelmed by a horrid stench, and immediately alerted police.

Later Tuesday, Ottawa police investigators confirmed the discovery of the second body part, a human hand, at an Ottawa Canada Post facility. The package was intended for the Liberal Party headquarters.

Police have not speculated or commented on what might have happened to the other missing limbs, or the victim’s head, but Montreal police at the blood-stained crime scene said some body parts are still unaccounted for.
