Canadian have deployed 'multiple resources' to York Landing in Manitoba, 80 km from remote town of Gillam where the suspects were last seen.
Canadian police announced they had zeroed in on a small community in Manitoba in their hunt for two fugitive teens suspected in three murders.
The suspects, identified as Kam McLeod, 19, and Bryer Schmegelsky, 18, have been on the run for more than a week.
Authorities say they believe the two are behind the killings of 23-year-old Australian Lucas Fowler and his 24-year-old American girlfriend, Chynna Deese, as well as of Leonard Dyck, a 64-year-old Canadian.
Since Tuesday, the village of Gillam, near Hudson Bay, has been at the epicenter of an intense manhunt involving tracker dogs, a drone and armored vehicles. The area features dense, sometimes nearly impenetrable forest.
But on Sunday night, the Royal Canadian Mounted Police (RCMP) said on their Twitter account they had sent multiple agents to York Landing, 204 kilometres southwest of Gillam, to investigate a tip that the two suspects were in or near the small community.
The RCMP informed the community to expect a significant police presence in the area.
In an earlier statement Sunday, the RCMP said they had received more than 200 tips in the past five days.
"None have established that the suspects are outside the Gillam area," the statement said, though it added it was possible the two suspects had altered their appearances and slipped out of the region, possibly with the unwitting help of an area resident.
"Officers are searching cottages, cabins, waterways and along the rail line for any sign of the suspects," the statement said. Remote areas were searched by both air and foot.
The Canadian Air Force provided two planes to help the search: a C-130 Hercules, manned with trained search-and-rescue spotters, and a CP-140 Aurora, a long-range patrol plane equipped with a sophisticated surveillance system, including infrared cameras and imaging radar.
The region is particularly inhospitable, with wild animals including wolves and bears, and swampy areas infested with mosquitos. The police tweeted a photo of a polar bear spotted during their search on Saturday about 200 kilometres north of Gillam.
Locals say conditions are brutal, and that the suspects, if on foot and unprepared, would have difficulty surviving for long.
The fugitives wound up in the Gillam region, located more than 1,000 kilometres north of Winnipeg, the capital of Manitoba, after driving more than 3,000 kilometres from British Columbia.
The teenagers were initially considered as missing after their car was found torched on July 19. But police then discovered Dyck's body near another burned-out vehicle believed to have been used by the pair.
The two young men have been formally accused in the murder of Dyck, a botany professor, and are suspects in the killings of Fowler and Deese, whose bodies were found on July 15 along a highway in northern British Columbia.
