Ryan Grantham, who appeared in an episode of the popular TV show "Riverdale," was sentenced to life in prison for murdering his mother.

Grantham will not be eligible for parole for 14 years, according to B.C. Supreme Court Justice Kathleen Ker, who called the case "tragic" and "heartbreaking."
Barbara Waite, Grantham's mother, was shot in the back of the head while playing the piano in their townhouse in March 2020.
