(FILES)This file photograph courtesy of the Service de Police de la Ville de Montreal (SPVM) shows Luka Rocco Magnotta (C) escorted by police upon arrival from Germany on June 18, 2012 at Mirabel Airport in Mirabel, Quebec, Canada. A jury must decide whether to send « Canadian Psycho » killer Luka Magnotta to prison for life or to hospital indefinitely, after hearing final arguments in his trial December 15, 2014. Magnotta has admitted to killing 33-year-old Chinese student Lin Jun. But he has pleaded not guilty to first degree murder, committing indignities to a body, harassing Canada’s prime minister and other charges. His defense attorney said Magnotta, 32, was « insane » at the time, and requires psychiatric treatment, not jail. Prosecutors, however, argued that it was all an act and that the killing was « planned and deliberate. » AFP PHOTO / Service de Police de la Ville de Montreal == RESTRICTED TO EDITORIAL USE / MANDATORY CREDIT: « AFP PHOTO / Service de Police de la Ville de Montreal » / NO SALES / NO MARKETING / NO ADVERTISING CAMPAIGNS / DISTRIBUTED AS A SERVICE TO CLIENTS ==
