The Regina sentencing hearing for one of two teenaged boys who killed 16-year-old Hannah Leflar heard from an expert witness Wednesday.

The defence called Dr. Terry Nicholaichuk, a clinical psychologist, who met with the 16-year-old boy three times and wrote two reports.

Nicholaichuk says the teen meets some of the criteria for borderline personality disorder, and likely suffers from a major depressive disorder.

The doctor says the boy does not meet the criteria for psychopathy.

Leflar was found dead 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.

A second boy has pleaded guilty to second-degree murder in the case, down from the original charge of first-degree murder. He is expected to be sentenced in September.
