(CNN) Authorities believe they have found the bodies of two Canadian men suspected of killing three people before beginning a long trek across the country last month, the Royal Canadian Mounted Police said Wednesday.

The bodies were found on the bank of the Nelson River after a weekslong manhunt focused in northern Manitoba, said Assistant Commissioner Jane MacLatchy, commanding officer of the Manitoba RCMP.

The scene was about five miles from where a car thought to be stolen by the pair was located last month, and close to where Kam McLeod, 19, and Bryer Schmegelsky, 18, were reportedly last seen July 22.

"I'm confident that it is them," she said, adding that an autopsy will confirm the identities of the deceased, who were from the Vancouver area.

MacLatchy said she could not say how they died, or how long they have been dead.
