A 60-year-old man has been found guilty of first-degree murder in B.C. Supreme Court in Chilliwack, for killing a 14-year-old girl who went missing in the Fraser Valley in 2005.

Jesse Blue West was given a life sentence with no eligibility of parole for 25 years for his role in the death of Chelsey Kayla Dawn Acorn.

West's son, Dustin Moir, was also convicted of first-degree murder in Acorn's death in an earlier trial and received a life sentence with no parole eligibility for 25 years.

West, then 54, and Moir, then 22, were arrested and charged with first-degree murder in 2007, months after hikers found the remains of 14-year-old Chelsey Acorn in a shallow grave in a remote area just off the Coquihalla Highway near Hope, B.C.

Acorn had been reported missing from a group home in nearby Abbotsford in June 2005.

In October, West had told the court that Acorn's death was accidental. He had said that in June 2005, he saw his son and Acorn having an argument, when Acorn suddenly fell over. West told the court he took her pulse, and found that she was dead.

West said he made a mistake by not calling 911, and instead trying to help his son hide the body.

Police said that West, a long-haul trucker in B.C. and Alberta, often worked and travelled with his son, and investigators said the pair frequently came in contact with at-risk youth, young women, runaways, and homeless people.
