MIAMI (AP) - Closing arguments are set in the trial of a South Florida woman accused of killing 4-year-old foster child Rilya Wilson in a case that shook up the state child welfare system.
    
Prosecutors and defense attorneys are scheduled Tuesday to make their cases before jurors following some eight weeks of trial. If convicted, 67-year-old Geralyn Graham faces a potential life prison sentence.
    
Investigators believe Rilya was killed in late 2000 but her disappearance wasn't discovered for some 15 months. That led to high-level resignations and changes within the Department of Children and Families as well as passage of several reform laws.
    
The state's case relies heavily in jailhouse informants who say Graham confessed to them behind bars. Graham has always maintained her innocence.
    
Jury deliberations are expected to begin Wednesday.
