An Iowa dad has been sentenced to life in prison in the death of his infant son.

Judge Richard Stochol sentenced 29-year-old Zachary Koehn of Alta Vista to life in prison without parole for his convictions for first-degree murder child endangerment causing death.

Koehn’s four-month-old son Sterling died after being left alone in a swing seat in his apartment in August of 2017. Doctors say the child died from malnutrition, dehydration and infection from a diaper rash caused by an unchanged diaper. Investigators said  maggots eventually crawled on the child while he was still alive.

Sterling’s mother, 21-year-old Cheyanne Harris, will be tried on the same charges in January.
