The Waterloo-Cedar Falls Courier reports it took the jury about four hours Wednesday to find 21-year-old Cheyanne Harris guilty of first-degree murder and child endangerment causing death.
The charges stem from the death of 4-month-old Sterling Koehn, whose body was found Aug. 30, 2017, in a maggot-infested diaper at an apartment. First responders found his body in a sweltering bedroom in a baby swing.
An autopsy shows he died of malnutrition, dehydration and an E. coli infection.
First-degree murder carries a mandatory sentence of life in prison without parole.
The baby's father, Zachary Koehn, already has been sentenced to life in prison in the case.
