LAKE COUNTY, Fla. - A Lake County woman accused of torturing her 10-year-old son to death is expected to change her plea during a hearing Wednesday. 

Kimberley Mills, of Tavares, and her boyfriend, Andre Walker, have been charged with first-degree murder, aggravated child abuse with aggravated battery and aggravated child abuse with malicious punishment in the death of Xavier Williams.

Investigators said the couple abused Xavier over several weeks, which led to his death in March. 

Mills and Walker pleaded not guilty to the charges last year.
