A porn actor is wanted in a gruesome case of dismembered body parts that were mailed to different places including the headquarters of the Conservative Party of Canada, police said.

Luka Rocco Magnotta, 29, is wanted for homicide, Montreal police said Wednesday at a news conference.

According to an official close to the investigation Magnotta worked as a porn actor and there is video of the crime. The official spoke on condition of anonymity because he was not authorized to talk publicly about those details.

Magnotta, believed to originally be from Toronto, was renting an apartment in a working-class Montreal neighborhood. It was behind that building that police found a man's torso in a suitcase in a heap of garbage Tuesday, police said. That same day, a foot was found in a package mailed to the Conservative party headquarters in Ottawa, and a hand found at postal warehouse in the Canadian capital. The package with the hand was addressed to the Liberal Party of Canada. Early testing shows the three body parts come from the same man, police said.

Police in masks combed through the blood-soaked Montreal studio apartment on Wednesday. A blood stained mattress remained there after they left.

“For most of the officers that were there all night long this is the kind of crime scene they've never seen in their career,” Montreal Police Cmdr. Ian Lafreniere said.

Lafreniere said they are investigating the possibility that other body parts might have been mailed. He said the suspect and the victim knew each other. He said it isn't linked to organized crime.

The packages with the foot and the hand had been mailed to Ottawa from Montreal. It wasn't clear why.

“As a father, I would have trouble sleeping at night knowing that the suspect was in my neighborhood,” Lafreniere said.

Police said Magnotta is also known by the names Eric Clinton Newman and Vladimir Romanov. They described him as white, 1.73 meters with blue eyes and black hair.

His internet presence indicates he is a bisexual porn actor and model. (AP)
