Shortly after 8 p.m., on March 30, 2013, police were called to the mall for a reported shooting.
Two men had been shot, one of whom died.
Within hours, police identified the deceased as Michael Nguyen, 23, of Toronto.
A few days later, Det. Rob North told reporters that Nguyen and the second victim had been shopping at the mall before being ambushed in the parking lot.
North is set to provide an update on the investigation at 11 a.m. on Monday.
