BELFAST, Maine (AP) — A prosecutor says a Maine woman accused of beating her 10-year-old daughter to death confessed that both she and her husband beat the girl a couple of times a day for months.

The murder trial started Friday for Sharon Carrillo. The case shocked the state and led to child welfare reforms.

The girl's stepfather, Julio Carrillo, is serving a 55-year sentence after pleading guilty to his role.

Sharon Carrillo contends both she and her daughter were victims of abuse at the hands of Julio Carrillo, who she blames for the death. Prosecutors say she's just as guilty.
