Gatineau police are investigating after a commemorative plaque was stolen from a west-end cemetery.

They said they were called to the Edey family cemetery on chemin Lattion just after 4 p.m. on Sunday, where a two foot by two foot plaque had gone missing from the front of the cemetery.

Metal thefts are common in Gatineau but the theft of a commemorative plaque is rare, according to police.

Replacing such a monument can cost thousands of dollars, while the resale value is only a small percentage of that amount.

Gatineau police said they’re trying to figure out if the plaque was made of copper or bronze.

Anyone with information can contact Det. Dominique Rondeau-Bergeron at 819-243-2345 extension 6207.

The Edey family established a farm in the area of what’s now known as Aylmer in 1806 after moving from Vermont.
