After nine days, Luka Magnotta's preliminary hearing has adjourned until next month.

The hearing this morning heard all of the crown's witnesses from Ottawa: two police officers, a Canada Post inspector, and the director of political operations for the Conservative Party of Canada.

Their testimony and all evidence are protected by a publication ban.

Magnotta, 30, is accused of killing and dismembering Concordia University student Jun Lin, 33.

A woman watching the proceedings in the overflow room hooked up to the courtroom via video conference got up and left during the testimony of the first witness, one of the police officers. She was heard muttering, "I can't take this", as photos were being presented during the testimony.

Magnotta, wearing a black bomber jacket and white t-shirt, remained impassive and staring straight ahead throughout most of this testimony except for a few minutes when he turned and looked away.

The courtroom's 25 seats reserved for the public and media were all taken and over a dozen people were in the overflow room for the ninth day of the hearing, which has seen the numbers of onlookers dwindle in the last couple of days.

The hearing has heard from 25 witnesses so far. When it resumes, a friend of Jun Lin and witnesses from Vancouver will be next to testify. Lawyers indicated they'd wrap things up during that week. The judge will decide how solid the evidence is and whether the case will be sent to trial.
