One of Hannah Leflar’s killers apologized at his sentencing hearing in Regina on Tuesday.

“I can’t apologize enough for what I’ve done,” the teen said, reading from a written statement.

He said he wasn’t in a stable state of mind when he killed Hannah, and that he wants to spend the rest of his life doing good.

“Everyone makes mistakes,” he said. “It’s what we do to right those wrongs that make us better.”

The teen said he’s found peace in God. Some members of Leflar’s family left the courtroom as he read.

“I know you may never forgive me for what I’ve done,” he said. “But I will never stop asking God for forgiveness.”

Leflar was found stabbed to death in her Regina home in January 2015.

The Crown is seeking an adult sentence for the teen, who pleaded guilty to first-degree murder earlier this year. However, the defence argued that a youth sentence would still hold the teen accountable.

“If he gets anything less than an adult sentence, then that isn't justice for our daughter,” Hannah’s mother, Janet Leflar said outside the courthouse.

“It’s not justice for us... and conveying the message that if you’re under 18, you can get away with murder."

The judge has reserved her decision on sentencing until July 5.

A second teenaged boy, who pleaded guilty to second-degree murder, is expected to be sentenced in September. He originally faced a charge of first-degree murder.
