Closing arguments in the hearing to determine whether or not the 19-year-old man who killed Hannah Leflar will be sentenced as an adult are expected Tuesday in Regina.

The hearing, which was scheduled to last two weeks, revealed many details about the killer, including his troubled childhood — the teen told a psychologist his mother tried to kill him as a child — how the killer discussed harming Leflar in online messages and how he had threatened suicide if he were to receive an adult sentence.

Hannah Leflar, 16, was killed in her home in January 2015. The killer, who acted with the help of another boy, was also 16 at the time and cannot be named under the Youth Criminal Justice Act.

On May 19, victim impact statements were read to the court. Leflar's mother, Janet, detailed how she has suffered since her daughter's death.

Janet Leflar said she has been unable to work and the family has been in financial turmoil.

"Wherever she is, you won't be going there," Janet Leflar said to her daughter's killer.

"I don't believe you have the capacity to appreciate what you've done."

The killer's state of mind has been discussed thoroughly during the two week hearing, which began May 8.

Psychiatrist Brent Harold testified that the teen displayed "psychopathic tendencies" while psychologist Terry Nicholaichuk said the teen scored low on a psychopathy test.

Harold also testified that the teen displayed a lack of remorse. Psychologist Elizabeth McGrath and psychiatrist Oladapo Soyemi testified at the hearing that the teen had expressed remorse to them about killing Leflar.

An adult sentence carries a term of life in prison with no chance of parole for 10 years while a youth sentence would amount to 10 years, involving time both in and out of custody.
