Police investigating the grisly killing of a Chinese student said posted packages containing the man's body parts also included notes.
The case was discovered last week when Jun Lin's left hand and left foot were sent to Canada's top political parties. The investigation spread to the other end of the country this week as more body parts were posted from Montreal to two schools in Vancouver.
Those parcels contained a right hand and a right foot and police said they would conduct DNA tests to confirm a match, Commander Ian Lafreniere of Montreal police said.
"They were the same limbs we were looking for," he said. The victim's head is still unaccounted for.
Mr Lafreniere said the parcels sent to the Conservative and Liberal parties, and at least one of the Vancouver packages contained a note. He declined to say to whom they were addressed or what they said, for fear of encouraging copycat crimes.
Mr Lin's lover, porn actor Luka Rocco Magnotta, 29, was arrested in Berlin on Monday and could be extradited to Canada by the end of the week.
Mr Lafreniere said Magnotta had either lived in Vancouver or passed through at one point, but could not otherwise say if he had a connection to those two schools.
In 2003 Magnotta worked on a porn movie for a company that was based in Vancouver, according to Jeff Vanzetti, webmaster for the US based internet Adult Film Database. It was not immediately known if the movie was filmed in Vancouver, however.
Investigators say Magnotta videotaped the killing and dismemberment in his apartment and posted it online. The video also shows the suspect eating parts of the body, police said.
A copy of the video viewed by The Associated Press did not show anyone eating the body but did show a man using a fork and knife on it.
Police suggested they had access to more extensive video of the killing, possibly an unedited version.
Magnotta was caught at an internet cafe in Berlin after evading police for days while he partied in Paris. He has told German authorities he would not fight extradition.
Magnotta arrived in Berlin on Saturday on a bus from Paris and stayed with a friend, or someone he met on the internet, for two nights before he was captured. Investigators in Germany were looking for more information on the person.
Mr Lin's parents, meanwhile, arrived in Montreal from China on Tuesday and met investigators and officials from Concordia University yesterday, said Zheng Xu, a press spokesman at the Chinese consulate.
Mr Lin, 33, was registered as an undergraduate in the university's department of engineering and computer science.
Yan Shi, head of Concordia's Chinese student association, who met the family at the airport, said: "It's heartbreaking. Lin's mother was very emotional. She was crying all the time ... She could barely walk. We had to help her."
Commander Denis Mainville, head investigator of the Montreal police major crimes unit, said officers would review hundreds of murder cases over the last 30 years throughout Quebec for any possible links to Magnotta.
Meanwhile, police said DNA tests have confirmed that the body parts posted to the Conservative and Liberal parties were Mr Lin's remains and they had footage of Magnotta sending the two parcels posted to Ottawa.
Police concerns about copycats grew yesterday after a fake foot made of rubber was found in a Montreal street. Mr Lafreniere said it had probably been used in film production.
