Skylar Prockner has had his appeal tossed out by Saskatchewan’s highest court.
His adult life sentence will now stand and he will remain in jail with no chance of parole for 10 years.
The teen killer of Hannah Leflar argued to the Court of Appeal that the sentencing judge, Justice Jennifer Pritchard, did not properly assess and weigh the evidence in the case to sentence him as an adult.
But in a unanimous decision that argument was rejected.
“The sentencing judge’s assessment and weighing of the evidence is entitled to deference,” Chief Justice Robert Richards wrote. “She did nothing in relation to this issue that would warrant or justify the intervention of this Court.”
Justice Ralph Ottenbreit and Peter Whitmore presided over the appeal with Richards.
Prockner pleaded guilty to stabbing to death his ex-girlfriend Hannah Leflar in January 2015.
At the time, Pritchard ruled that an adult sentence was appropriate because of the brutal nature of the crime and the events leading up to the fatal stabbing.
Prockner, who was 16-years-old at the time of the murder, stalked and plotted to harm Leflar and her then-boyfriend in a plan dubbed ‘Project Zombify’.
For two years Prockner had been cloaked under the provisions of the Youth Criminal Justice Act until his adult sentence almost a year to the day.
A second teen, who pleaded guilty to the second-degree murder of Leflar, remains anonymous.
