Karl Olivier Desmeules, 31, was last seen in Montreal’s Saint-Laurent borough on the evening of November 24, 2024. He is 5 feet 10 inches, about 170 pounds, with brown hair and brown eyes. At the time he was reported missing he wore a royal blue tuque, a red or burgundy hooded winter coat, beige pants and carried a military-style green backpack.

Family members grew concerned after Desmeules stopped showing up for work and failed to return home; his girlfriend first raised the alarm. He had made some unsettling comments before he vanished and had not been in contact with anyone since. Police say he travelled by bicycle or on foot and is bilingual in French and English.

The Service de police de la Ville de Montréal opened an investigation and deployed a mobile command post near Marcel-Laurin and Côte-Vertu boulevards on December 6, 2024 after determining he was last seen in a nearby business. No significant findings have been announced and the case remains unresolved.

If anyone saw Karl in late November 2024 or has information about his disappearance, please share what is known.
