Ryan Grantham sentenced to life in prison for matricide 

"Diary of the Wimpy Kid's star Ryan Grantham, who pleaded guilty to second-degree murder conviction of his mum Barbara Waite in March of 2020 

was sentenced to life imprisonment with a parole ineligibility period to 14 years 

in the court of Justice Kathleen Ker in B.C. Supreme Court in Vancouver. 

Calling the incident "tragic and heartbreaking", Justice Ker said that the statement of the victim 

from his sister demonstrated the extent to which "life-shattering" the crime was. 

In addition, it was an "saving grace" Grantham chose not to embark on a shooting spree in accordance with Canadian Broadcast Corporation. 

While she was sitting at her piano inside the family's Squamish home, Grantham killed her once using an 22 rifle.
