The mystery of why two teenage friends went on a bloodthirsty, random killing spree in northern Canada that claimed the lives of Australian tourist Lucas Fowler, his US girlfriend and a university lecturer may soon be revealed.
The Royal Canadian Mounted Police will hold a briefing on Friday (Saturday AEST 6am) to release findings of the tragic case.
Kam McLeod, 18, and Bryer Schmegelsky, 19, are suspected of shooting dead Mr Fowler and girlfriend Chynna Deese on July 15 after finding the couple and their broken-down van on the side of an isolated highway in northern British Columbia.
Mr Fowler, 23, from Sydney, and Ms Deese, 24, from North Carolina, fell in love after meeting in Croatia on a backpacking trip and were on a Canadian road trip.
McLeod and Schmegelsky were accused of murdering 64-year-old University of British Columbia botany lecturer Leonard Dyck four days later, stealing Mr Dyck’s Toyota RAV4, setting their own Dodge pick-up truck on fire and sparking a nationwide manhunt.
The teenagers were found dead on August 7 in bushland more than 3000km east near the northern, desolate Manitoba town of Gillam.
They are believed to have taken their own lives and filmed a “last will and testament” video message on one of their phones.
The RCMP has suppressed most details of the case, including what was on the video message or if other notes or clues were left behind to explain why two teenagers who just weeks earlier were working at a Vancouver Island Wal-Mart suddenly became killers.
The RCMP will brief reporters and then hold a press conference.
Mr Fowler is the son of NSW Police chief inspector Stephen Fowler.
NSW Police sent two homicide detectives to Canada to assist the investigation, liaise and support family members.
