CRYSTAL LAKE | A Crystal Lake man accused of confining a woman against her will and seriously injuring her will be tried Dec. 6 on a charge of first-degree kidnapping. 

Christopher James Moore, 27, beat the woman so severely during the Aug. 2 incident she required transport to the hospital via helicopter, according to law enforcement.

Moore pleaded not guilty Aug. 29 to the kidnapping charge, as well as additional felony charges of willful injury resulting in serious injury and domestic abuse assault by strangulation.

He also faces a misdemeanor charge of false imprisonment.

A witness heard a woman yelling for help outside a window at her residence, a criminal complaint states.

The witness told a Hancock County deputy she saw Moore throw the woman around and hit her several times in the front yard of the home.

Court documents say a neighbor told law enforcement he heard the alleged altercation from inside his home, and could hear "what sounded like screaming from a female and a male stating he would kill her."

Law enforcement had difficulty communicating with the woman, due to pain in her jaw and from yelling in pain when being touched, court documents say.

She was taken to Hancock County Health System, where it was determined she had sustained possible head and neck injuries, and transported to Mercy Medical Center-North Iowa via helicopter.

The original trial information filed Aug. 11 by Hancock County David Solheim charged Moore with domestic abuse assault by strangulation, willful injury resulting in serious injury and false imprisonment.

Iowa Assistant Attorney General Laura Roan filed amended trial information Aug. 24 that included all those charges as well as an additional charge of first-degree kidnapping.

If he is convicted on the kidnapping charge, Moore faces a mandatory life sentence without the possibility of parole.
