A Spirit Lake man is facing an attempted murder charge after an early morning assault on a woman.

Spirit Lake police say they were sent to a home this morning. Dispatchers had gotten a 9-1-1 call during which no one would speak. Officers found a woman at the home who had been violently assaulted with a knife. She was taken to Lakes Regional Healthcare then life flighted to a Sioux Falls hospital.

Dickinson County sheriff’s officers, Okoboji and Arnolds Park police and the Iowa Division of Criminal Investigation helped process evidence.

Detectives say 39-year-old James Michael Naujock is charged with first-degree kidnapping, attempted murder, willful injury, going armed with intent and domestic abuse assault. He also faces counts of interfering with official acts and obstruction of emergency communications.

Naujock is being held in the Dickinson County Jail. More charges are possible and investigators are still working the case.
