Ryan Grantham of Riverdale was sentenced to life in prison for murdering his mother.

According to a statement acquired by E! News on September 22 from BC Prosecution Services, the 24-year-old, who previously starred in the CW series Riverdale, was sentenced to life in prison with the potential of release in 14 years. At Grantham's Sept. 20 sentence, the court also imposed a lifelong weapons restriction on him. According to the statement, both the life sentence and the limitation on owning a handgun are obligatory in British Columbia for second-degree murder.

Ryan's attorney, Chris Johnson, told E! News that Grantham has "worked incredibly hard to turn his life around" since his imprisonment.

"He's had a lot of psychiatric help, and he's battled with what he's done and how to deal with it," Johnson said in a statement, "but he wants to be able to spend the remainder of his life to making reparations."

According to a statement acquired by E! News in June from Dan McLaughlin of the BC Prosecution Service, he pleaded guilty in March to second-degree murder in the case of his mother's death.

Prosecutors claimed Grantham shot his mother, Barbara Waite, in the back of the head while she played piano at home in March 2020, according to CBC News reporter Karin Larsen, who virtually attended the sentencing hearing in June. Grantham recorded a video of himself after committing the murder in which he admitted to the crime and videotaped his mother's corpse.

According to the CBC, Grantham filled his car the next day with firearms, ammunition, and Molotov cocktails with the intent of killing Canada's Prime Minister Justin Trudeau at Rideau Cottage in Ottawa. Grantham, on the other hand, changed his plans and reversed his automobile, intending to perpetrate mass carnage either Vancouver's Lions Gate Bridge or Simon Fraser University, where he was a student.

Grantham did not carry out the plan, instead going to the Vancouver police station later that night and telling an officer, "I killed my mother."

Crown prosecutor Michaela Donnelly cited two psychiatric evaluations in court in June, stating that Grantham was suffering from violent desires and severe depression prior to killing his mother.

Grantham gave a statement in court on the third and last day of his June hearing, reflecting on his conduct.

"It kills me to think about how much of my life I've squandered," he stated at the time. "Saying sorry feels meaningless in the face of something so heinous. But I apologize from the bottom of my heart."
