The jury took a closer look Tuesday at photos showing the contents of four parcels that were mailed to political offices in Ottawa and schools in Vancouver.
One of them contained a neatly written note on pink paper that included an obscenity and read: "Stephen Harper and Lauren (sic) Teskey will know who this is. They f--ked up big time!!"
Teskey is Harper's maiden name.
Magnotta faces a first-degree murder charge in the May 2012 slaying and dismemberment of Chinese student Jun Lin, 33.
He is also charged with criminally harassing Harper and other members of Parliament; mailing obscene and indecent material; committing an indignity to a body; and publishing obscene material.
Crown prosecutor Louis Bouthillier told jurors in his opening statement Monday he intends to prove the act was deliberate and planned. He said the evidence will show Magnotta killed Lin, dismembered his corpse and sent his hands and feet by mail to Ottawa and Vancouver.
Magnotta, 32, pleaded not guilty on Monday to all five charges. He has admitted to authoring the crimes, but his lawyer has indicated he will mount a defence of mental disorder to seek a verdict of not criminally responsible.
On Tuesday, the jurors were able to view photos taken in 2012 by three Montreal police crime-scene technicians.
One officer's photos showed the parcels that were mailed to Ottawa and Vancouver.
Caroline Simoneau testified about items recovered from their police counterparts in both cities in June 2012: Canada Post boxes and their contents.
One of the parcels mailed to Ottawa was destined for the Conservative Party of Canada, while the other was sent to Liberal party headquarters in Ottawa. The Vancouver ones were sent to two schools.
One of the Vancouver-bound boxes had a heart drawn in black marker at the bottom, while another contained dark stains.
Among the items recovered from the boxes were pink tissue paper, gift bags and a handwritten note in each, including at least one bearing the name of "Lauren Teskey." While the name is misspelled, it clearly refers to Harper's wife.
In another note addressed to the Liberal headquarters, she is mentioned again. "You need to speak to Laureen Teskey & her family, lots to hide!," it read.
One of the boxes sent to Vancouver also contained a threatening poem that read: "Roses are red, violets are blue, the police will need dental records to identify you, bi--h."
Another officer's photographs took jurors inside the infamous Apt. 208 in a west-end Montreal building where Lin's slaying is alleged to have occurred.
Chantal Turmel told the jury she was instructed by investigators that a video had been circulating on the Internet depicting the dismemberment of a man.
She testified homicide investigators asked her to find certain items that figured prominently in it — notably, a poster from the movie "Casablanca," a yellow T-shirt and a wine bottle Turmel testified was used to sodomize the victim. The label on the bottle carried the words "Wish for Love."
She says she found all three outside the building in a garbage truck.
Later, Turmel showed photos from inside the bachelor apartment, which was rented by Magnotta. It was largely empty of actual contents and Simoneau testified they gathered numerous personal items in the trash outside the building.
As police gathered evidence, there were red marks and splotches found throughout the tiny apartment. A large stain soaked through the partially covered mattress found in the unit. There was also red pools under the vegetable crisper and the freezer in the refrigerator.
Forensic biologists will testify next week as to what those marks were.
Turmel also snapped the photo of an inscription in red marker inside the closet: "If you don't like the reflection, don't look in the mirror. I don't care."
"It smelled a bit rotten, " Turmel testified, referring to the apartment.
Finally, a third officer's photos traced the route to a heavy brush-filled area where detectives found a human skull on July 1, 2012, more than one month after the discovery of a torso.
Richard Dionne took photographs of the route from the Angrignon subway station to an adjoining Montreal park where a mummified skull was found in tall grass. It was largely unidentifiable except for bits of hair and teeth.
Throughout, the jury remained impassive as the images flashed on screens in front of them.
Magnotta's lawyer, Luc Leclair, told the court Monday his client has been diagnosed with borderline personality disorder shortly before the slaying and that he suffered from schizophrenia.
Bouthillier also told jurors the first 53 seconds of the so-called murder video actually shows footage shot of a different man one week earlier. He said the rest of the video shows Lin.
The eight female and six male jurors are expected to view the video in the third week of the trial.
Leclair spent much of Tuesday afternoon cross-examining Simoneau and registering as defence exhibits several of the items recovered from the trash.
The trial is expected to last between six and eight weeks and feature some 60 witnesses.
