Quebec’s independent investigations bureau (BEI) will set up a command post Monday morning at the site of a June 22 shoot-out that left a Montreal police officer, a civilian bystander and the suspect dead.

Les enquêteurs du BEI seront sur place avec un poste de commandement mobile qui sera localisé sur l’avenue de Courtrai au coin du boulevard Décarie entre 10h et 14h ce lundi 6 juillet 2026.

In a communique, the BEI said it wanted to find eyewitnesses to the incident, particularly those who may have recorded the shootings on their phones or other devices.

Montreal police have announced that a public commemorative ceremony for Const. Mohamed Lamine Benredouane, the officer who was killed in the shoot-out, will be held July 7 at the Bell Centre.

Benredouane, 34, was killed shortly after police responded to a report of a gunman near Trans Island and de Courtrai Aves. The suspected shooter was also killed, as was a bystander, and another police officer and civilian were also shot in the incident.

The dead civilian was identified as Michel Mizrahi, a local member of the Chabad Jewish community.

BEI investigators will staff the command post located at De Courtrai Ave. and Décarie Blvd. from 10 a.m. to 2 p.m.

Anyone with any information that could further the BEI investigation can also contact the office through its website.
