The crime took place in 2020 and shocked the world. After killing his own mother, Grantham himself turned himself in to authorities and confessed to shooting Barba Waite, who was 64 when she died, in the back of the head.
Some extra details about the crime were revealed during the trial. After killing his mother, the actor recorded the corpse on video, confessing the crime to the camera as he arranged the body in what was described as "a semi-religious scenario".
Only one day after the event did Ryan flee the scene, but went straight to the police station to turn himself in.
At the trial, an actor's diary pointed out other things. There was information in it about the plan to also assassinate Justin Trudeau, Prime Minister of Canada.
Furthermore, the actor would be rehearsing a shootout at Simon Fraser University or the Lions Gate Bridge.The shocking thing is that both places are pretty busy in Vancouver.
Still young, with 24 years old, Ryan already has a resume full of more than 30 jobs. While most are just as extras and small characters, he can tell you he's been in Supernatural, iZombie, Falling Skies, and more.
His last role on TV was in the fourth season of Riverdale, a series in which he gave life to the character Jeffery, responsible for the death of Fred Andrews (Luke Perry), the father of Archie (K.J. Apa).
How did the crime happen?
In March 2020, at the actor's house, his mother played the piano with her back to him. After taking marijuana, as she said, Ryan shot Barbara Waite in the head.
According to the authorities responsible for the case, at the time he was only 21 years old and even recorded a video next to his mother's body.
Soon after, he would have gone out to get money to produce Molotov cocktails. Afterwards, he watched television for two and a half hours before returning home.
At bedtime, he still covered his mother's body with a sheet and, the next day, placed candles around her.
As previously stated, in addition to killing his mother, Ryan planned to take the life of the Canadian Prime Minister, Justin Trudeau, with the justification that this would cause a great impact on the country.
Now Ryan is in complicated situations, as he will pay for the crime with life imprisonment.
