Father Testifies In Alta-Vista Murder Trial Of Four-Month Old

Mount Pleasant, Iowa – The murder trial for Zachary Koehn of Alta Vista continues this week from Mount Pleasant.  

Koehn took the stand Friday to plead his case.  He said he entrusted the care for his son Sterling Koehn to the child’s mother, Cheyanne Harris, who is being tried separately.  

Koehn admitted to not changing his son’s diapers due to a weak stomach, drug use, working long hours and not stepping up as a father.

The trial resumes tomorrow.
