BELFAST, Maine (AP) — The office of Maine's attorney general says the stepfather of a 10-year-old old girl killed in February 2018 is expected to plead guilty to her killing.

An office spokesman says Monday that 52-year-old Julio Carrillo will plead guilty to depraved indifference murder. He's expected to appear in Waldo County court next Monday.

Authorities allege Marissa Kennedy died in Stockton Springs after being beaten for months by her mother and stepfather who tried to make her death look like an accident. Sharon and Julio Carrillo had both pleaded not guilty to murder in Kennedy's death.

The crime shocked the state and led to a push for child welfare reform.

Julio Carrillo's attorney didn't immediately respond to request for comment Monday.
