The father of a child that was found dead in a maggot-infested diaper in a baby swing has been sentenced to life in prison.
Zachary Koehn received his mandatory sentence after a judge denied his request for a new trial Tuesday, according to the Waterloo-Cedar Falls Courier.
A jury convicted Koehn of first-degree murder last month.
4-month-old Sterling Koehn had been in the same diaper for nine to 14 days when his body was found in the swing Aug. 30, 2017, at his parents’ Alta Vista apartment, the Courier reported.
Nurse and county rescue squad EMT Toni Friedrich testified Tuesday that she was the first to arrive at the apartment after Koehn called 911 to report the baby had died.
Friedrich said Koehn showed no emotion when he led her to the dark, hot bedroom where the baby’s body was.
The baby’s “eyes were open, and it was a blank stare,” she said.
Friedrich said when she touched the baby’s chest, his clothing was crusty. When she moved his blanket, gnats flew up, she said.
