Actor Ryan Grantham has been sentenced to life behind bars for killing his mother. The British Columbia Supreme Court handed down the by-the-book second-degree murder punishment to former ‘Riverdale’ and ‘Diary of a Wimpy Kid’ actor in Vancouver. Notably, reports suggest that the actor has to stay in jail without the possibility of parole for 14 years. The actor turned to police soon after shooting his 64-year-old mother, Barbara Waite, in the back of the head on March 31, 2020. For more news and updates, stay tuned to ETimes.
