A judge ruled on Wednesday that Sharon Carrillo is competent to stand trial for the murder of her daughter.

The State Medical Examiner determined that 10-year-old Marissa Kennedy died from battered child syndrome, and said there was evidence of months of abuse. Kennedy lived in Stockton Springs with her mother and her step-father. Julio Carrillo was sentenced in August to 55 years in prison for depraved indifference murder.

Sharon Carrillo's attorney has argued that his client was also abused and that she has limited mental ability, stating that her IQ is in the 4th or 5th percentile. WABI-TV reports a judge has deemed her competent to stand trial. Jury selection will begin immediately.
