David Mailloux, 27, disappeared from Saint-Alexandre-de-Kamouraska, Quebec after being last seen on April 21, 2019. He left on foot from a home on Rang St-Adolphe and was seen walking near the junction of Route 289 and Autoroute 20. Mailloux did not own a car; he is 5 feet 10 inches, about 170 pounds, with brown eyes, black curly hair and a full black beard. When last seen he wore a long black hooded coat, pale washed-out blue jeans and light beige sneakers.

Family worried about his safety noted he had health challenges that could cause disorganization. Investigators learned he had asked about taxi fares to Ottawa or to cross into Maine but reportedly lacked funds; the trip never began. The Sûreté du Québec carried out searches with ATVs and canine teams and later issued public appeals that produced tips but no conclusive leads. A specialized missing persons unit remains assigned and the family reported no contact as of April 2020.

Does anyone in the Rivière-du-Loup or Saint-Alexandre-de-Kamouraska areas remember seeing Mailloux that evening or have information about his movements after he was last seen?
