He was sentenced to life in jail with a minimum period of imprisonment of 17 years.
Wilson, 22, died of blunt force injuries to the head, neck, abdomen and face.
In July, a jury delivered a unanimous verdict of guilty for Patricia Samson following a week-long trial.
While the Crown's case was that she drove and helped her son to "get rid" of evidence at Fosbender Park at the night of the murder, the defence said she just drove her son to the location but did not know that he had killed Wilson.
Samuel Samson and Wilson had a girl together, who was born in July 2019. The girl was found with Patricia Samson the day after her mother was murdered.
The two-year-old is being raised by Wilson's family.
