A Canada-wide warrant is out for the arrest of 31-year-old James Boucher for his alleged role in the murder of Tricia Boisvert.
Boucher is wanted on charges of being an accessory after the fact and causing an idignity to a body.
The main suspect in the killing, 30-year-old Philippe Steele-Morin, was arrested Monday in Gatineau.
He was formally charged with second-degree murder in a Montreal courtroom Tuesday.
36-year-old Tricia Boisvert was last seen on Jan. 17 at her apartment on Notre-Dame St. W. in Little Burgundy.
Her body was found six days later in a wooded area near Quyon in the Pontiac region.
Investigators believe that Boucher is somewhere in the Outaouais region.
Anyone with information regarding his whereabouts is being asked to contact police immediately.
