Aboubakr Omari, 28, pleaded guilty to a charge of manslaughter on Thursday at the Montreal courthouse, having been initially charged with second-degree murder. The tragedy occurred on February 2, 2024, in Montréal-Nord, where Omari killed his roommate, Seghir Mehiris, during an altercation. Having arrived in Canada in the summer of 2023, Omari lived with three Algerian compatriots, including the victim. Their cohabitation deteriorated due to a dispute concerning a monetary debt and the sharing of cannabis.
