This week Dr. Robert Sutherland, a witness called by Rylan Twigg’s lawyer Ingrid Hess, has been on the stand.

His testimony is part of a voir dire, which is a trial-within-a-trial to determine if the evidence can be used in the judge’s decision.

Twigg and Scout elected a judge-only trial.

Sutherland is with the University of Lethbridge’s Behavioural Neuroscience Department.

Hess wanted him to address questions regarding Twigg’s cognitive abilities, as she has said it’s suspected that her client suffers from undiagnosed fetal alcohol spectrum disorder- or a similar cognitive issue.

Co-accused Scout is out on bail during the remainder of the trial, but Twigg remains in custody and has not had a bail hearing since his arrest.
