The search for two British Columbia murder suspects has yielded no sign of the teenagers, so police say they are scaling back their manhunt.

Officers have searched more than 11,000 square kilometers of wilderness but there has been no sign of Bryer Schmegelsky, 18, and Kam McLeod, 19.

RCMP says the search is not over, but resources will be scaled down over the next week.

Schmegelsky and McLeod are charged with second-degree murder in the death of Leonard Dyck, whose body was found earlier this month in northern B.C.

The pair is also suspected in the shooting of Australian Lucas Fowler and his American girlfriend Chynna Deese. Fowler and Deese were found dead on the Alaska Highway near Liard Hot Springs, B.C.

Ontario Provincial Police (OPP) is investigating after someone reported seeing two men who looked similar to McLeod and Schmegelsky in the northeastern community of Kapuskasing.

OPP say a suspicious vehicle was reported driving through a construction zone Wednesday morning but officers were unable to track it down.
