In 1963, the Town of Muskego elected their last Constable, William E. Bohlman. He remained as the Town Constable until 1967 when city officials organized the Muskego Police Department.
On December 15th, 1967, at 12:01 AM, the City of Muskego Police Department began operations. Chief Ervin W. Kraus directed the Department, comprised of three sergeants and seven patrolmen. Civilian employees carried out dispatch duties. During opening ceremonies, the key to the police department was thrown away, symbolizing the department’s accessibility to the public twenty-four hours a day.
The first Muskego police station was an old, two story, seven-room house. The kitchen served as a combination roll call room, court clerk’s office, and storage area. In addition to this, the kitchen also served as an employee lunchroom and a prisoner holding area. Since there was no actual detention area in the station, prisoners were handcuffed to the "kitchen table". Luckily, there were seldom more than four prisoners in custody at the same time, so the four kitchen legs were usually enough.
Chief Kraus planned for a new state-of-the art facility from day one. His dream came true on June 5th, 1978, when the department moved into a new facility at the present site. Chief Kraus was only able to enjoy his efforts for a mere three months. On August 19th, 1978, Chief Kraus died of a heart attack. Chief Richard F. Scholz then served until 1985, leaving to pursue another career.
