The brother of a North Carolina woman murdered alongside her Australian boyfriend during a Canadian road trip says the couple 'were a perfect match'.

British Deese spoke with DailyMail.com on Friday, five days after his sister, Chynna, and her byfriend, Lucas Fowler, were shot dead on the side of a road in rural British Columbia.

A witness claims they stopped to speak with the couple by the side of their broken down blue minivan about 15 miles south of Liard Hot Springs on Sunday afternoon.

Their bodies were discovered on the Alaska Highway early Monday morning, and local police have now launched an investigation into the double murder.

British told DailyMail.com that the couple were intrepid travelers who met in Croatia two years ago.

Fowler, who hails from Sydney, Australia, was working on a ranch in Canada before he set off on a road trip of the northwest of the country with Deese late last week.

The pair were only two days into their ten day journey around the region when they were killed.

Cops are now investigating the mysteriously slaying, and there are reports they are looking into a slew of unsolved murders in the area over the last 40 years that could have been carried out by a serial killer.

British told DailyMail.com that his family were not worried about Deese and Fowler setting off on their adventure, explaining that the pair were well-traveled and that they had meticulously planned their road trip.

'They had traveled Europe and Asia together... they were always sensible and cautious,' he stated.

He further added that his parents were left 'shocked' by the sudden and violent deaths and were in contact with Canadian police.

Deese and Fowler were travelling in the upper region of British Columbia, a place notorious for 'The Highway of Tears' - a 450 mile stretch of road upon which 50 women have disappeared or been murdered since 1970.

Police are asking anyone who traveled the stretch of highway between Sunday evening and Monday morning to make contact.

A blue minivan with Alberta number plates was found at the scene and police would like to speak with drivers who saw the vehicle or who may have dashcam footage.

It is not yet clear why the couple were attacked.

The Daily Telegraph reports that Deese and Fowler 'may have been the victims of a serial killer'.
