The Canadian teenagers investigators believe murdered three people at random in a homicidal spree across the country had admitted to the killings in a series of videos recorded on a digital camera, authorities said Friday.

The suspects, 19-year-old Kam McLeod and 18-year-old Bryer Schmegelsky, killed themselves in a wooded area of Manitoba in August during a weeks-long manhunt, police said.

The camera with the confession videos was found near their bodies; the cause of death was suicide by gunfire, officials said.

The teens were wanted in the death of a college botany lecturer and a girlfriend-boyfriend pair, American Chynna Deese and Australian Lucas Fowler, police said.

The videos have not been released, but their contents were revealed to The Associated Press.

In August, a 30-second clip was made available to family members of the former fugitives.

In the first video, Schmegelsky confessed the pair had killed all three of the victims, police said Friday.

The two gave no explanation for the murders.

Both teens then say they plan to hijack a boat on Hudson Bay in northern Canada and sail to Europe or Africa, cops said.

In the next clip, Schmegelsky says they reached the river but they may have to kill themselves because the river was too fast. They again admit to the killings in the clip, authorities said.

In a final video, they announce they were delivering their last will and testament and that they wish to be cremated.

“If there was a motive, it is gone with the accused,” said Kevin Hackett, the assistant commissioner of the Royal Canadian Mounted Police. He added that the pair appeared “cold, remorseless” in the videos.

A manhunt for the pair stretched across three rural Canadian provinces, ending in August when their bodies were found along with two firearms.
