MONTREAL – A human head found in a park belongs to a Chinese student who police say was dismembered by a Canadian porn actor, authorities in Montreal confirmed Wednesday.

The head of Jun Lin was the last body part still missing since he was killed and dismembered in May.

Luka Magnotta is accused of dismembering his lover Lin and mailing the body parts to Canadian political parties and schools. He pleaded not guilty to murder charges last month.

Investigators found the head in Park Angrignon after the major crimes unit received a tip. The park is a few miles south of Magnotta’s apartment.

Montreal police spokesman Robert St-Onge said police now believe that they have recovered all of Lin’s remains. He said the family has been informed.

Investigators say Magnotta, 29, posted a video online showing him having sex with the dismembered corpse. A second, unedited version of the video seen by police shows him eating parts of the body, officials said. Police say Magnotta and Lin were in a relationship.

The case became known when a package containing a severed foot was found at Canada’s ruling Conservative Party headquarters on May 29. That same day, a hand was discovered at a postal facility, addressed to the Liberal Party of Canada.

Lin’s torso was found in a suitcase at a garbage dump in Montreal outside Magnotta’s apartment building.

About a week later, a missing foot and hand were found mailed to two schools in Vancouver. Police said notes were included in most of the packages but declined to say what they said.

Magnotta, who fled to Europe before the body was discovered, spent a few days partying in Paris before moving on to Berlin, where he was caught last month as he read stories about himself at an Internet cafe. He did not contest his extradition from Germany and arrived in Montreal last month.
