Montreal police probed yesterday a horrifying new twist in the “Canadian Psycho” case after new body parts turned up in the mail while the suspect awaited extradition from Germany.

The authorities were still trying to determine if the human hand and foot discovered in separate packages on Tuesday at two Vancouver schools were indeed those of the killer’s victim, 33-year-old Chinese student Lin Jun.

Luka Rocco Magnotta, a 29-year-old porn actor, was arrested in Berlin on Monday after a week-long international manhunt and is awaiting extradition to Canada for murdering Lin, believed at one point to have been his lover.

Mr Magnotta allegedly filmed himself on the night of May 24-May 25 killing Lin and dismembering the victim’s body before sending a foot and a hand to the headquarters of Canadian political parties.

The victim’s torso, which has also been identified as belonging to Mr Lin, was discovered in a suitcase outside Mr Magnotta’s apartment building, but his head and his second hand and foot were all unaccounted for before Tuesday.

Montreal homicide investigators have taken over the Vancouver probe into whether the latest body parts belonged to Mr Lin, who had been studying computer science at Concordia University in Montreal before his gory death.

Vancouver police said the packaging and addresses on the boxes sent to schools there were similar to those on the gruesome parcels discovered earlier this week at political offices in eastern Canada.

Mr Magnotta, who fled Canada on May 26, initially to Paris, was picked up on Monday on an Interpol warrant by German police in an Internet cafe in Neukoelln, a working-class district of Berlin.

It is not clear when he will be extradited to Canada but the move is expected in the coming days.

Authorities said Mr Magnotta will face charges of first degree murder and committing indignities to a body. He is also expected to be charged with publishing and mailing obscene matter.
