An Iowa man was convicted Tuesday of first-degree murder in the death of his infant son who was found in a maggot-infested baby swing last year. Jurors took less than an hour to convict Zachary Paul Koehn, 29, of Alta Vista, of first-degree murder and child endangerment causing death, the Waterloo-Cedar Falls Courier reports . The murder conviction carries a mandatory prison sentence of life without parole.
Koehn had blamed his son’s mother for the death of 4-month-old Sterling Koehn. A trial is pending for the 21-year-old mother, Cheyanne Harris.
The couple were arrested after medics were called to an apartment on Aug. 30, 2017, and found the infant dead in a swing in a dark, hot back bedroom. An autopsy showed the baby died of malnutrition, dehydration and an E. coli infection caused by being left in a maggot-infested diaper for up to two weeks.
