Port Huron, MI – A St. Clair County mother pleaded guilty Wednesday to second-degree homicide in the 2018 death of her 3½-year-old son, Matthew Maison.
According to the St. Clair County Prosecutor’s Office, 33-year-old Amanda Mae Maison appeared before Judge Cynthia Lane of the 31st Circuit Court on November 5, 2025, where she admitted to her role in Matthew’s death.
Matthew was found deceased in February 2018 at the family’s home in Port Huron Township. The incident was reported by the mother of Maison’s then-boyfriend, Maurice Houle, who has since been charged with first-degree homicide and remains in the St. Clair County Jail awaiting trial.
During Wednesday’s plea hearing, Maison admitted that she and Houle were in a two-year relationship during which both allegedly abused Matthew. She also acknowledged concealing the child’s injuries from Child Protective Services and law enforcement between 2016 and 2018.
Maison told the court she “willfully and wantonly” allowed an abusive environment that led to Matthew’s death and participated in a plan to conceal the manner of his death.
As part of her plea agreement, Maison will provide truthful testimony at Houle’s upcoming trial, expected in early 2026. Her bond was revoked, and she was remanded to jail pending sentencing. The offense carries a potential life sentence.
Sheriff Mat King commended detectives for their persistence, saying, “Matthew is finally beginning to get the justice he deserves. Although this is not the end, I am confident justice will be served.”
