Matthew de Grood, the man accused of stabbing five people to death at a house party in Brentwood last year will stand trial for the murders.

Justice J.D. Holmes made the decision on Friday morning, stating the preliminary hearing determined that there was enough evidence to move it forward to trial.

The Crown called 13 witnesses to the stand during the preliminary hearing. The details of what actually occurred during the proceedings, however, is under a publication ban.

Neil Wiberg, Crown lawyer said the proceedings were very tough for the victims' families to hear. "They got to hear witnesses describe key points of the evidence, so that must be very difficult for family members to hear."

de Grood's defence counsel, Allan Fay, said the preliminary inquiry was routine as far has he was concerned. "The Crown called evidence that I wanted to hear. Some of it I knew in advance what it would be, but there's always surprises, there's always extra things that come out and that's always expected."

Fay says a preliminary trial is an invaluable tool in the court process.

The court has not made a determination on whether or not de Grood was criminally responsible for his actions.

de Grood is charged with five counts of first degree murder after police say he stabbed five people to death at a house party in a northwest home.

Zackariah Rathwell, Kaiti Perras, Jordan Segura, Lawrence Hong, and Joshua Hunter were all celebrating the end of classes when they were alleged stabbed by de Grood, who was an invited guest.

The arraignment date has been set for May 29.

de Grood's lawyer says the trial will likely last four to six weeks.
