The two teenagers suspected of murdering three people on remote highways in northern British Columbia died by what appears to be suicide, Canadian police have confirmed.

Royal Canadian Mounted Police (RCMP) confirmed the two bodies discovered in Northern Manitoba on August 7 were the wanted teens Kam McLeod, 19, and Bryer Schmegelsky, 18.

“The RCMP can also confirm that the two died in what appears to be suicides by gunfire,” the RCMP said in a statement.

“While both individuals were deceased for a number of days before they were found, the exact time and date of their deaths are not known. However, there are strong indications that they had been alive for a few days since last seen in July and during the extensive search efforts in the Gillam area.”

Police located two firearms near the bodies and forensic analysis is underway in order to confirm the weapons were connected with the July murders of Australian tourist Lucas Fowler, his girlfriend Chynna Deese and Vancouver man Leonard Dyck.

Authorities confirmed on Monday that post-mortems had been completed on the bodies.

Schmegelsky would have turned 19 last Monday, August 4, but he may have died before that.

Canada-wide warrants were issued for McLeod and Schmegelsky after Canadian authorities officially charged the pair with second-degree murder of Vancouver man Leonard Dyck, whose body was discovered near their burned out Dodge in northern British Columbia on July 19.

What followed was a three-week pursuit stretching 3000km across northern Canada.

The Royal Canadian Mounted Police deployed a massive contingent of personnel and were assisted by Royal Canadian Air Force planes equipped with infra-red cameras and imaging radar to search 11,000 square kilometres around the town of Gillam and surrounding wilderness, but earlier this month announced the search had been scaled back.

More than 500 homes and buildings were canvassed and train tracks, trails and other locations were searched but authorities failed to make any confirmed sightings.

The breakthrough came in early August with the discovery of "items" on the shoreline of the Nelson River near Gillam, about 8km from where the duo dumped their Toyota RAV4 getaway car on July 22.

These included a sleeping bag, half-eaten pork chops and orange peel found alongside the vehicle the pair set fire to, suggesting they ate their rations of meat and fruit before heading into the depths of the nearby swampland.

Australia Lucas Fowler, 23, and his American girlfriend Chynna Deese, 24, were found shot to death near their broken down van on July 15 along the Alaska Highway in northern British Columbia, more than 3000kms away from where the search ended in Gillam.

Fowler and Deese met two years ago backpacking in Croatia, fell in love, and were on a road trip through Canada when they were murdered.

Four days later, Leonard Dyck's body was discovered two kilometres from McLeod and Schmegelsky's burned-out truck on Highway 27 near Dease Lake, about 470 kilometres from the Alaska Highway crime scene.

The teens were previously believed to be missing until investigators released a shocking update that they were suspects in the three homicides.
