Canadian actor Ryan Grantham, best known for playing Jeffrey Augustine on Riverdale, has been sentenced to life in prison for killing his mother, Barbara Waite..

This case was heard last Wednesday, September 21, in the Supreme Court of British Columbia, Canada.. As you know, Grantham pleaded guilty to the death of his mother six months ago.. The murder happened in 2020, writes TMZ.

Grantham shot his mother in the back of the head while she was playing the piano at home, prosecutors say..

In court, the artist told how he committed the murder, and even showed a video filmed a few hours after the murder, in which he confesses to the murder and shows the dead body of his mother.

The day after his mother was killed, he stocked his car with weapons, ammunition, Molotov cocktails and directions to Rideau Cottage, where Canadian Prime Minister Justin Trudeau lived..

Detectives investigating the case say Grantham later admitted to trying to kill Trudeau and wrote about his goal in a magazine..

Under the terms of the sentence, Grantham will not be eligible for parole for the first 14 years in prison..
