A 29-year-old Davenport man was in the Scott County Jail on Wednesday on charges he raped a woman in the 1700 block of Iowa Street earlier this week.

Nathan D. Ronnau of 3438 Heatherton Drive, Apt. 5, is charged with first-degree kidnapping and second-degree sexual abuse-forcible rape.

About 3:40 a.m. Monday, police responded to the 600 block of East 15th Street, Davenport, regarding a sexual assault that occurred on Iowa Street, according to Ronnau's arrest affidavit.

Ronnau attacked the victim from behind, wrapping his arm around her throat and knocking her face first onto the sidewalk on the west side of Iowa Street, the affidavit states.

Ronnau continued to choke the victim with his arm until the victim lost consciousness, and then he dragged her to an area east of Iowa Street between a large tree and a large bush, the affidavit states. Ronnau sexually assaulted her, the affidavit states. The victim regained consciousness during the assault, and she struggled and struck the defendant in the face with her hands, the affidavit states.

Ronnau hit the victim in the face and threatened to kill her several times, telling her he had a knife, the affidavit states.

Assistant Davenport Police Chief Don Schaeffer said the victim was treated at Genesis Medical Center, East Rusholme Street, Davenport. She suffered numerous cuts, bruises and other injuries, the affidavit states.

The victim identified the defendant in a photo lineup.

Ronnau told police he was intoxicated early Monday to the point that he did not remember what happened, the affidavit states.

First-degree kidnapping is a Class A felony that is punishable in Iowa by life in prison. Second-degree sexual abuse-forcible rape is a Class B felony that is punishable by up to 25 years in prison.
