What happened
Case facts: Incident type: Shooting/mass violence | Method/weapons: Attack type: firearm attack.
On June 4, 2014, RCMP officers were shot in Moncton, New Brunswick, resulting in three deaths and two injuries. The RCMP commissioned an independent review to establish what occurred and to develop recommendations to assist members in future responses.
Subsequent RCMP updates and published documents focus on implementation of recommendations, including tactical response, communications, equipment, and after-care for members.
What we still need: a consolidated, source-verified timeline for the shootings and manhunt (times, locations, engagement sequence) suitable for this dossier.
