Shirley Harrison, 74, of Chicago, Illinois, died on December 31, 2001, from a gunshot wound inflicted by her husband, Thomas Harrison. Shirley had recently suffered a stroke and was hospitalized when Thomas shot her while she lay in a hospital bed; he later described the act as a mercy killing because of her declining health.

Thomas Harrison was arrested and charged with first-degree murder, pleaded guilty, and received a 20-year prison sentence. The case attracted media attention and prompted public discussion about end-of-life choices, caregiving, and domestic violence.

Did anyone who knew Shirley or the family notice signs of abuse or discuss her care before December 31, 2001?
