The Supreme Court of Canada has denied an appeal by Jared Baker, found guilty of first-degree murder in 2007 for killing 19-year-old Olivia Talbot. Talbot was pregnant at the time.

At Baker's trial in 2007 the court heard Baker and Talbot had been friends since elementary school and started to experiment with crystal meth while they were in Grade 8.

Baker testified that he was convinced he was the son of Satan and by "crushing the serpent's head" -- meaning killing Talbot and the fetus -- he could "walk like Jesus."

The Crown argued that Baker was angry at Talbot for using drugs while pregnant and knew what he was doing when he shot her in the stomach.

The defence said at the time that Baker should be found not criminally responsible because he was in a drug induced psychosis at the time.

A jury convicted Baker of first-degree murder, but in August of 2009 Baker appealed his conviction to the Alberta Court of Appeal. He lost that appeal by a margin of two-to-one.

This outcome from Canada's highest court was the last possible avenue of appeal for Baker.

Talbot's mother Mary traveled to Ottawa for the hearing.

Last week she told CTV News "...you can't have everybody who gets drunk or smokes a joint or does whatever, going off on their own and doing whatever they feel like it."

Baker continues to serve a life sentence with no chance of parole for 25 years.
