The Royal Canadian Mounted Police in British Columbia have named 19-year-old Kam McLeod and 18-year-old Bryer Schemegelsky as the suspects in the double homicide of 23-year-old Lucas Fowler and 24-year-old Chynna Deese.

Officers were previously searching for McLeod and Schmegelsky after they found the truck they were driving caught fire south of the Stikine River Bridge on Highway 37.  While investigating the scene of the fire, police found the body of a man in the area and are working to identify who the man is.

On Tuesday, police released surveillance video of Fowler and Deese and a sketch of the person of interest in the couple's murders.

"Investigators are working through a number of tips and tasks, including interviews with individuals who saw or spoke with the couple, analyzing forensic and digital evidence along with reviewing hours of CCTV and dashcam video footage," RCMP said.

Surveillance video from July 13 shows Deese and Fowler stopped at a gas station around 7:30 p.m. Police say they entered the station's store at about 7:37 p.m., returned to their vehicle and drove away at 7:46 p.m.

On Monday, RCMP confirmed Lucas Fowler and Chynna Deese were shot. Police also said they determined the 1986 blue Chevrolet van with Alberta license plates belonged to Fowler. Their bodies were found 12 miles south of Liard Hot Springs on the morning of July 15.

Police say Fowler's family arrived in British Columbia to meet with investigators. Fowler's father is a police officer with the New South Wales Police Force and has been accompanied by his fellow officers. 

"The Deese family continue to receive regular updates and currently have no plans to travel to British Columbia," RCMP said. "The BC Coroners Service is also investigating these deaths and will not be providing any further updates."

Kam McLeod is described as 6 foot 4 inches tall and about 169 pounds. Police say he has facial hair, dark brown eyes and brown hair. Bryer Schmegelsky is described as also being 6 foot 4 inches and about 169 pounds. Police say he has sandy brown hair.

Investigators say they have confirmed the two men have left British Columbia and were spotted in northern Saskatchewan. They were seen driving a gray 2011 Toyota RAV4. 

The Royal Canadian Mounted Police has asked people traveling through the area to be cautious. 

"We encourage people to camp in known or established locations," police said. "In addition, general safety precautions continue to apply. Make sure family or friends are aware of your travel plans, establish check-in times to provide updates and make sure that if your plans change you let someone know."

RCMP is asking anyone with information to contact them at 1-800-543-4822 or 778-290-5291. Police say some information about Deese and Fowler has been posted online, but they are advising the public to contact investigators first before publishing information on social media.

Police are telling the public the suspects should be considered dangerous and to not approach them. If they are seen, people are asked to call 911 immediately.
