David Jean Cottard search ramps up in Montreal

Montreal police are setting up a command post as they continue to search for David Jean Cottard, a Joliette, Que. man missing since Dec. 15.

Investigators will be on the corner of Ste-Catherine and St-Urbain streets between 9 a.m. and 8 p.m. in the hope of gathering information about Cottard's disappearance.  

They are inviting anyone with information to come forward.

Cottard disappeared somewhere in the 500-metre stretch between Complexe Desjardins and The Bay department store in downtown Montreal and hasn't been seen since.

The 42-year-old commutes from Joliette to his office in downtown Montreal every day.

On Dec. 15, he left work to get lunch and then disappeared after making what his partner Lynda Champagne described as "normal banking transactions" at an ATM machine.

Champagne said Cottard never returned to work and never fetched his car, which he'd left at the Joliette bus station in the morning.

Anyone with information can also call the anonymous tip line Info-Crime at 514-393-1133.
