In the latest twist, people who knew the family of 12-year-old Charlie Bothuell say a pattern of harsh discipline may have contributed to the Detroit boy’s disappearance.

The boy’s step-mother expected in court Friday, Monique Dillard-Bothuell, 37, was arrested Thursday on a parole violation unrelated to the boy’s disappearance. She had been previously convicted for purchasing a pistol without a permit. Her 4-year-old son and 10-month-old daughter have been turned over to Child Protective Services.

Dillard-Bothuell’s arrest came a day after the 12-year-old was found alive and well in the basement of his father’s home. Detroit police and the FBI had been looking for Bothuell after he was reported missing by his father, who said he disappeared on June 16.

Officers found Bothuell while executing a search warrant at his father’s home as part of the investigation into the child’s disappearance. It’s not clear if the boy had been there the entire time. Officers had been inside the home before, and cadaver dogs searched the house last week.

Bothuell was initially taken to a hospital for an evaluation, questioned by police, and released to his birth mother.
