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 said.
The head of Jun Lin, 33, was the last body part still missing after he was killed and dismembered in May.
Luka Magnotta is accused of dismembering his lover Mr Lin and sending the body parts to Canadian political parties and schools. He pleaded not guilty to murder charges last month.
Mr Lin's head was the only remaining missing body part until Sunday, when police spokeswoman Anie Lemieux said investigators found it in Park Angrignon after the major crimes unit received a tip. The park is a few miles south of Magnotta's apartment.
"It had been there for quite some time, but we won't go into details, partly out of respect for the family and friends of the victim," said Ms Lemieux. "What is important is what we were looking for has been found and the rest of the investigation can continue."
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. Police say Magnotta and Mr Lin were in a relationship.
The case began 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 centre, addressed to the Liberal Party of Canada. Mr Lin's torso was found in a suitcase at a rubbish 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 socialising 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 on a Canadian military plane.
Along with a first-degree murder charge, Magnotta is charged with defiling Mr Lin's corpse. He is also charged with harassing Canadian prime minister Stephen Harper and members of parliament, and publishing and mailing obscene material.
