KIEL, Wis. (AP) — State agents are helping Kiel police investigate the deaths of three people.

Police say officers responded to an emergency call to a home Sunday about 7 p.m. When they arrived, officers were unable to make contact with anyone in the house. Police entered the home and found three people dead.

Authorities haven’t released the circumstances surrounding the deaths or the genders or ages of those involved. The state Division of Criminal Investigation is working the case.

Officials say they don’t believe the public is in danger, but did not explain why.

“At the present time, we don’t believe the public is in danger, but the investigation is ongoing,” reads a statement from the Wisconsin Department of Justice.

The DOJ’s Division of Criminal Investigation is leading the investigation.

Kiel is a city in Calumet and Manitowoc counties with a population of about 3,700.
