Luka Magnotta trial: Police were faxed directions to victim's head

An investigator with the Montreal police's major crimes unit testified that police were sent a fax from an Ontario-based lawyer with written directions on how to find the last missing body part of 33-year-old victim Jun Lin.

Antonio Paradiso, a member of the investigative team searching for the victim’s head, said the three-page fax was addressed to him and sent from Raphael J. Feldstein’s law office on July 1, 2012.

The witness read out a portion of the text for the court: “You may find what you’re looking for by following these directions: Exit the Angrignon subway station,” followed by more precise instructions guiding officers across a parking lot and to a path around a pond.

Paradiso told the court he immediately went to Montreal’s Angrignon Park with his partner to follow the instructions, but officers had problems identifying which pond the letter was referencing.

He called the lawyer’s office for more information, without success.

Police found the victim’s severed head later that day with the help of a canine unit.

Luka Magnotta has pleaded not-guilty to first-degree murder and four other charges, but has admitted to the physical act of killing Lin, along with the facts outlined in the other charges. His lawyer has told the court he intends to prove Magnotta is not criminally responsible because of mental illness.

The Crown alleges the killing was premeditated.

Suspect was co-operative: witness

Paradiso was also among the group of six officers and a psychiatrist who went to Berlin to escort Magnotta back to Montreal after his arrest on June 4, 2012.

The witness told the court he was in charge of watching Magnotta, and that the accused was, “very quiet, very co-operative, and slept most of the time.”

Magnotta was handcuffed and his feet were shackled during the flight. Paradiso recalled having to cut the accused’s food for him, for practical reasons.

Paradiso also told the court that during the initial stage of the investigation, after officers had found some papers containing Magnotta’s name, he had believed the accused was the victim.

More from bloodstain expert

Earlier on Wednesday, Magnotta’s defence lawyer, Luc Leclair, focused on several items as he cross-examined the forensic biologist who analyzed DNA and bloodstains found in the accused’s apartment.

Jacinthe Prévost, wearing gloves, was asked to hold up a wine bottle and Casablanca film poster police found in the trash outside the apartment where the crime took place. She said she found the victim’s DNA on the mouth of the bottle and his blood on the poster.

Prévost said an attempt had been made to clean blood from the apartment, particularly in the bathroom, but the cleaning was poorly done and many bloodstains were still visible.

The biologist also examined sperm stains found on sheets and clothing, but did not identify any belonging to the victim.

The trial continues Wednesday afternoon with a new witness, toxicologist Catherine Lavallée.
