Tuesday marks the 10th anniversary of one of the worst police shootings in Canadian history.

A gunman targeting police opened fire in the north end of Moncton, N.B., on the evening of June 4, 2014.

Five RCMP officers were shot during the 20-minute shooting rampage before the gunman disappeared into a wooded area.

Const. Dave Ross, 32, Const. Fabrice Gevaudan, 45, and Const. Douglas Larche, 40, died in the incident.

Two other constables — Éric Dubois and Marie Goguen — were also shot but survived their injuries.

The lone gunman kept the city on edge for more than 29 hours until he was captured just after midnight on June 6.

Justin Bourque pleaded guilty to three counts of first-degree murder and two counts of attempted murder and was sentenced to life in prison with no chance of parole for 75 years.

However, his parole eligibility was later reduced to 25 years after the Supreme Court of Canada ruled the section of the Criminal Code that allowed for consecutive parole ineligibility in cases involving multiple murders is unconstitutional.
