Harris has pleaded not guilty to first-degree murder and child endangerment resulting in death. She was arrested in August 2017 after medics found 4-month-old Sterling Koehn dead in the swing in a dark, sweltering bedroom.

An autopsy shows he died of malnutrition, dehydration and an E. coli infection caused by being left in a maggot-infested diaper for up to two weeks. The boy’s father, Zachary Koehn, already has been sentenced to life in prison .
