Alex West: A British journalist who met with Magnotta in December 2011 to discuss Internet videos featuring cats being killed was the Crown's star witness. An email sent by Magnotta in the days following their meeting indicated slaying the cats was the beginning and that a filmed human killing would be next. Jun Lin was slain and dismembered in May 2012, less than six months later. West also surreptitiously taped a conversation with Magnotta in one of the few times the jury heard his voice at length because he did not testify.
Frank Rubert: As police were finding Lin's torso in the trash behind a Montreal apartment and identifying Magnotta as the suspect, the accused was reaching out to the German man on a gay chat site as he tried to get out of Paris. Rubert knew nothing of Magnotta's crimes and took him in. They drank heavily and partied with prostitutes during roughly 72 hours before Magnotta's arrest and Rubert noted nothing abnormal about the accused's behaviour. Rubert said he felt ill after reading in the papers about his short-term boarder being sought for the murder and dismemberment.
Feng Lin: The jury heard from Jun Lin's former lover that their relationship ended about a dozen days before his slaying. He testified Lin was under intense family pressure to marry and settle down. Feng Lin said his former lover did not do drugs and was not into bondage. After their split, they remained on good terms and texted 50 times a day. Feng Lin said he began to worry when his texts went unanswered, beginning May 25, 2012.
Defence experts: Dr. Joel Watts / Dr. Marie-Frederique Allard: Roughly half of the trial was devoted to the findings of forensic psychiatrists. Two of them for the defence met with Magnotta for hours and each produced lengthy reports he was schizophrenic, in a deep psychotic state at the time of the slaying and unable to distinguish right from wrong. Their testimony was the only account provided by Magnotta of what happened the night Lin was killed and each version he gave was slightly different.
Dr. Joel Paris: The last psychiatrist to see Magnotta — roughly one month before Lin's slaying. He found no evidence of schizophrenia or bipolar disorder during his observation. In fact, he diagnosed Magnotta as having borderline personality disorder based on his strained relationships, compulsive behaviour and unstable moods marked by highs and lows. "There was no evidence of an extended period of psychosis or chronic psychosis ... we didn't think that either of these were justified by the data we had," Paris said.
Marc Lilge, German police officer: The officer who finally put an end to the hunt for Magnotta after confronting him at a Berlin Internet cafe with a group of cadets on June 4, 2012. Lilge was persistent as Magnotta initially said he was Kirk Trammel, an American from New York, but had no identification on him. Lilge pressed as Magnotta stuttered, shook and sweated before blurting out, "'You got me, I'm Mr. Magnotta, I'm the man you're looking for,'" Lilge quoted Magnotta as saying. The police officer testified that the accused had a smirk on his face as he was transported to a detention centre.
Logan Valentini: During the trial, it emerged that Magnotta had admitted to psychiatrists he was the source of rumours linking him romantically to convicted killer Karla Homolka. The jury heard form Logan Valentini, Homolka's older sister, who'd since changed her name. Her name appeared on one of the body part packages bound for Vancouver. Her testimony was brief, but provided the tidbit that Homolka was living in Quebec again.
