Riverdale actor who murdered his mother allegedly had plans to kill Justin Trudeau

Ryan Grantham is being sentenced in British Columbia after pleading guilty to second-degree murder in March.

Ryan Grantham, the Canadian actor who pleaded guilty to second-degree

murder in March in the killing of his mother, allegedly plotted to kill Canadian Prime Minister Justin Trudeau as well.

Grantham, 24, began his sentencing hearing Monday in the British Columbia Supreme Court,

which will determine how long he is to serve before being eligible to apply for parole. Second-degree murder carries a mandatory life

sentence, and the period of parole ineligibility ranges from 10 to 25 years.

Grantham shot his 64-year-old mother, Barbara Waite, in the back of the head as she played piano in March 2020.

He pleaded guilty to second-degree murder earlier this year,

after initially being charged with first-degree murder.
