Overview

• RCMP confirmed that the suspect known as 'Mr X' was the third person who tested the bomb on Vancouver Island weeks before Flight 182 exploded off Ireland.
• Officials said the man recently died without ever being charged in connection with Canada's deadliest act of terrorism.
• Privacy legislation prevents authorities from naming the suspect despite his confirmed involvement in the bombing.
• Despite the 2005 acquittals of two primary suspects, investigators continue to pursue leads, seeing little prospect for a new trial.
• Families of victims and officials from Canada, Ireland and India are attending services this week to commemorate the 40th anniversary.
