A judge has decided that Skylar Prockner will be sent to the Saskatchewan Penitentiary to serve his sentence.

The decision came down in a Regina courtroom Friday afternoon.

Prockner, who is now 19, has been at a youth facility since he received an adult life sentence with no chance of parole for 10 years. He pleaded guilty to first-degree murder earlier this year in the death of Hannah Leflar.

Leflar was 16-years-old at when she was killed in 2015. She was an honours student who had just been named to the top of her class.

During the sentencing hearing, court heard that he stabbed Leflar multiple times after waiting outside her house for her to get home from school. Her body was found by her stepfather.

The Crown argued for an adult sentence, while the defence argued that Prockner had no criminal record prior to the homicide and suffered from mental health issues.

He was sentenced as an adult after several months of argument. The decision lifted a publication ban on his name, allowing the media to release it.

He had filed an application with the court to stay at a youth facility until his 20th birthday, but as a result of the decision on Friday, he’ll be transferred to the penitentiary immediately.
