CHARLES CITY — A Boone man convicted of child endangerment in Floyd County has lost an appeal of his case.

Nathan Jacobson was taking care of a two-month-old baby on October 17th of 2016 when the infant suffered multiple bruises on the face and head, subdural bleeding, retinal bleeding and an altered mental state. Jacobson is accused of causing the injuries either by dropping, shaking and/or slapping the child.

Jacobson was originally charged with child endangerment causing serious injury, a Class C felony punishable by up to ten years in prison, but as part of a plea agreement, he agreed to plead guilty to child endangerment causing bodily injury, a Class D felony. District Judge Dedra Schroeder sentenced Jacobson to five years in prison.

Jacobson contested his conviction and sentence, saying a risk assessment tool used to help determine his sentence violated his due process rights.

The Iowa Court of Appeals has upheld his conviction and the majority of his sentence, but remanded the case back to district court to address a restitution issue.
