SAINT-JEAN-SUR-RICHELIEU, Que. -- Mourners are gathering on a military base southeast of Montreal for a regimental funeral for an RCMP officer who died after a crash between his vehicle and a farm tractor.

Dozens of Mounties dressed in red serge and Stetsons are solemnly marching to the sounds of bagpipe music in memory of Richer Dubuc, who died on March 6 in Lacolle, near the U.S.-Canada border.

Dubuc, 42, was a seven-year veteran of the force and a father of four.

Uniformed police officers as well as emergency first responders are also joining the procession, which is led by a black hearse.

A native of Joliette, Que., Dubuc began his career with the Codiac Detachment in New Brunswick in November 2009.

He joined the Integrated Border Enforcement Team based in Saint-Jean-sur-Richelieu, Que., in January.
