Three women and one man were taken into custody Wednesday after the Shawano County Sheriff’s Department executed a search warrant on a residence in the town of Richmond.
The sheriff’s department said the search warrant was part of an ongoing drug investigation.
The four subjects, all from the Shawano area, have been referred to the district attorney’s office for charges.
Items of evidence were also seized, but authorities did not provide any further details.
The sheriff’s department was assisted by Shawano and Stockbridge-Munsee police departments, the Waupaca County Emergency Response Unit, state Division of Criminal Investigation and the U.S. Drug Enforcement Agency.
The incident remains under investigation.
