Yves Castonguay, 50, was last seen leaving his home on foot in Gentilly, a sector of Bécancour, Quebec, at about 6:20 p.m. on Tuesday, November 21, 2006. He walked away in an unknown direction and never returned or made contact with family or friends.

At the time he disappeared he was wearing a navy blue sweatshirt with international local 62 on it, blue jeans, and black shoes. The Sûreté du Québec’s Bécancour MRC detachment opened an investigation shortly after he was reported missing and asked the public for any tips; confidential information could be passed to the province’s criminal information line. The reason for his departure and his intended destination remain unknown, and the case has grown cold.

Did anyone living in Gentilly or passing through the area on November 21, 2006, see Yves or notice someone matching his description that evening?
