(CNN) The manhunt for two young men suspected in the killing of three people in Canada shifted to a remote community of about 500, but a tip on the suspects' possible whereabouts has not panned out, authorities said Monday.

The Royal Canadian Mounted Police had urged residents of York Landing, a small community in Manitoba located along the eastern bank of the Nelson River, to remain inside, lock their doors and windows and to "report anything suspicious."

"We're making a plea to the public to send in tips," RCMP spokeswoman Cpl. Julie Courchaine said.

Authorities have said the two suspects Kam McLeod, left, and Bryer Schmegelsky are wanted in connection with three killings.

Investigators had focused the search on Gillam, a tight-knit community of about 1,000 people, before turning their efforts to York Landing, about 90 kilometers (55 miles) southwest.

Courchaine said police received a tip around 5 p.m. Sunday that two men matching the suspects' description were seen in York Landing, an area so remote she said it's only accessible by small plane or a two-hour ferry ride.
