HALIFAX -- The case involving two people accused of plotting to open fire at a Halifax shopping mall will return to provincial court on June 12.

Twenty-three-year-old Lindsay Kantha Souvannarath of Geneva, Ill., and 20-year-old Randall Steven Shepherd of Halifax are each charged with conspiracy to commit murder.

They also face charges of conspiracy to commit arson, illegal possession of dangerous weapons and making a threat through social media, none of which has been proven in court.

During a hearing in court Friday, lawyers said they needed more time to review documents in the case and dates were tentatively set to hold a preliminary hearing in July.

A Crown document alleges the offences took place between Jan. 6 and Valentine's Day.

The Crown alleges the offences involved the Halifax Shopping Centre and were carried out in concert with James Lee Gamble, a 19-year-old man found dead in his Halifax home.
