Two people accused of plotting to attack the Halifax Shopping Centre on Valentine's Day of last year made a brief appearance Thursday morning in Nova Scotia Supreme Court.

Lindsay Kanitha Souvannarath and Randall Steven Shepherd are facing a variety of charges including conspiracy to commit murder.

The pair were arrested Feb. 13, 2015, just hours before police say they were going to launch an attack at the mall. Both have been in custody ever since.

Lawyers had originally planned to hold a hearing later this month to discuss what evidence could be introduced at their jury trial.

Evidence includes online postings

However, the lawyers decided the hearing is not necessary and Souvannarath and Shepherd will go on trial beginning in May of next year.

Much of the evidence against the pair involves online postings.

A third suspect, James Gamble, shot himself and was found dead at his parents' home the day before Souvannarath and Shepherd were arrested.

Gamble left behind a blog filled with images of death, shootings and references to the 1999 Columbine High School massacre in Colorado, Adolf Hitler and Nazis.
