BELFAST — A Stockton Springs mother who stood accused of the depraved indifference murder of her three-year-old son has been found guilty in Waldo County Superior Court Oct. 18. 

Jessica Trefethen, 36, faces of a sentence of at least 25 years and up to life imprisonment for the June 20, 2021, death of her son, Maddox, who had been abused for much of his short life and died from blunt force trauma. 

The trial against Trefethen began Oct. 5 and following a brief break due to COVID, concluded Oct. 18, with the guilty verdict. 

An affidavit revealed that bruises were observed on Maddox’s arms, legs, abdomen, and head. Maddox had three partially healed abrasions on his face and forehead, which were reportedly covered in stick-on tattoos. He also had deep tissue bruising on his buttocks and internal bleeding in his abdomen. Additionally, Maddox had bleeding in his brain and was missing three teeth, which appeared to be “at least two separate events,” according to the medical examiner who performed Maddox’ autopsy. 

Trefethen is expected to be sentenced in December, though no official date has been set, according to a court clerk.
