Ryan Grantham confessed to murdering his mom and then filmed her lifeless body.
A former actor on Riverdale and Diary of a Wimpy Kid was coming off the rails when he shot his mother in the head as she played piano — to keep her from seeing him murder Prime Minister Justin Trudeau.
The bizarre details came to light during sentencing submissions in a British Columbia courtroom this week.
In March, Ryan Grantham, 24, pleaded guilty to second-degree murder in the March 31, 2020 slaying of his mother, Barbara Anne Waite, in their Squamish home. The crime carries a mandatory life sentence. The Crown is seeking 17-18 years of parole ineligibility.
“He put the crosshairs on the back of her head, closed his eyes, and pulled the trigger,” Crown prosecutor Michaela Donnelly said.
Grantham had roles in Diary of a Wimpy Kid and The Imaginarium of Doctor Parnassus. His last acting credit was a 2019 episode of Riverdale.
His road to murder was punctuated with madness, court heard. He had rehearsed his mom’s slaying and even made videos of his plans.
In footage he shot following the brutal killing, Grantham took one final star turn: He confessed to murdering his mom and then filmed her lifeless body.
Court heard Grantham then packed his car with his three guns, ammo, a dozen Molotov cocktails, supplies for camping, and a map. The map had directions to Rideau Cottage in Ottawa, where Trudeau is living with his family.
The former child actor admitted to cops his plan to assassinate the prime minister and kept a private journal of his murderous musings. But he didn’t get far driving across the country on his homicidal quest before he turned back and surrendered to Vancouver Police.
Prosecutor Michaela Donnelly cited two psychiatric reports that showed Grantham’s dramatic unravelling. The reports said that prior to the murder he had been suffering an “intense period of clinical depression and “experiencing urges to commit violence and kill himself.”
The troubled thespian murdered his mom because he wanted to “spare her” of seeing the bloodshed he was poised to unleash on Trudeau. At the time of her murder, Barbara Anne Waite was fighting cancer.
“She was vulnerable and Ryan gave her no chance to defend herself. It pains me to know he was a danger to her life,” his sister Lisa told the court, adding she and her aunt “fear his release from prison.”
