The boy vanished from Saint-Eustache, northwest of Montreal, on Thursday and he and his father were stopped by police in eastern Ontario nearly 24 hours later.

The boy was found in Lacasse's stolen vehicle and his father was arrested.

Police said today they are searching with the use of a helicopter a 500-kilometre stretch of highway between Mont-Tremblant, Que., heading northwest towards Rouyn-Noranda, Que.

There's been no trace of Lacasse, who is from Lachute, Que., about 80 kilometres northwest of Montreal, despite an intensive search with volunteers over the weekend.

The suspect in the case, a 41-year-old man, remains in hospital in Ottawa, putting plans to transfer him into Quebec provincial police custody on hold.
