Missing Teenagers Suspects In Aussie's Murder In Canada

Canadian authorities have named two teenagers as suspects in the murder of Australian tourist Lucas Fowler and his American girlfriend Chynna Deese.

Kam McLeod, 19, and Bryer Schmegelsky, 18, from Port Alberni, British Columbia, were originally deemed missing but in a dramatic twist, police made an "unprecedented appeal to the public" at a press conference on Tuesday.

"If you spot Bryer or Kam consider them dangerous," said the Royal Canadian Mounted Police's Sergeant Janelle Shoihet.

"Do not approach, do not take action and call 911 immediately."

The teens were first loosely connected to the murder of Fowler and Deese when their Dodge pickup was found burning near an unidentified man's body close to Dease Lake, in northern British Columbia.

Sgt Shoihet said McLeod and Schmegelsky have since been spotted in northern Saskatchewan, a Canadian province hundreds of kilometres away.

"Given these latest developments, Cameron and Bryer are no longer considered missing," Sgt Shoihet said.

"The RCMP are now considering Cam McLeod and Bryer Schmegelsky as suspects in the Dease Lake suspicious death and the double homicide of Lucas Fowler and Chynna Deese."

Fowler, 23, from Sydney, and Deese, 24, from North Carolina, were stranded on the highway after their blue 1986 Chevrolet van broke down on the afternoon of July 14 about 470km away from where the burning Dodge was found.

They were found shot dead in a ditch near the highway the next day.

The RCMP originally played down speculation of a crime spree linking the murders of Fowler and Deese to Friday's discovery of the body, the missing teenagers and the burning Dodge pickup.

Authorities are yet to identify the dead body found near the burning Dodge.

The teens are believed to be driving a grey 2011 Toyota RAV4.
