The 4-month-old baby was found lifeless in a baby swing wearing a maggot-infested diaper.

LE MARS, Iowa — Jurors have found an Iowa woman guilty in the death of her infant son, whose lifeless body was found in a baby swing.

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 in Alta Vista. 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.
