As police once again search the shoreline of Riviere des Prairies for 10-year old Ariel Jeffrey Kouakou, they're getting some help today from a specially-trained dog brought in from Halifax.
This dog can detect cadavers, even those submerged in water.
Police says the most likely scenario in the boy's disappearance nearly three weeks ago is that he went through the ice on the river and drowned.
A Hydro Quebec icebreaker will be helping police with the operation again today.
