Luka Rocco Magnotta hunched as low as he could in the prisoner's box Thursday as the jury hearing his murder trial viewed a graphic and gruesome video depicting the death of Jun Lin.
The jurors had been warned from the beginning of the trial they would be required to watch a video that showed the dismemberment and desecration of Lin's body.
They remained impassive as a copy of the 10-minute video, downloaded by the Montreal police, was shown in court.
Earlier on Thursday, the trial heard from a postal-counter employee who said Magnotta exchanged boxes on May 25, 2012, because they were too small for what he intended to send.
Tomokazu Lee was working behind the Canada Post counter at a pharmacy outlet in the city's west end.
Lee told the jury he remembered Magnotta because he appeared at the counter twice that day: once to exchange boxes and once in the early evening to send two packages.
Magnotta was caught on the store surveillance video mailing two boxes, which contained Lin's body parts. He appeared calm and paid in cash.
The boxes remained at the pharmacy for 48 hours before they were sent out, Lee testified.
In all, four packages were mailed: one each to Conservative and Liberal offices in Ottawa and two others to schools in Vancouver.
The trial resumes Friday.
