Police said the shootings occurred at three locations in the Wausau area.
The officer, from the Everest Metropolitan Police Department in Schofield, was killed in the line of duty, Sparks said. The name of the officer was not released.
"This was one suspect, at this point in time. He has been taken into custody," Sparks said at a media briefing where he did not take questions.
Sparks did not provide a possible motive for the shooting, and said the Wisconsin Department of Justice's Division of Criminal Investigations is handling the investigation. Jason Smith of the DCI said the investigation is complex.
It is not clear precisely where the four fatalities occurred.
