Division of Forensic Sciences

Welcome to the Division of Forensic Sciences (DFS) which houses the Wisconsin State Crime Laboratories (WSCL). The WSCL provides forensic science testing for a variety of disciplines for all Wisconsin communities. The forensic science testing performed is unbiased and of the highest quality. The WSCL employs top-notch scientists many of whom are nationally recognized as leaders in the forensic science community. We welcome you to explore our forensic science testing capabilities, investigate our internship opportunities or contact us.


The Wisconsin State Crime Laboratories Celebrate 75 Years





The WSCL was established on August 8, 1947 after Chapter 165 of the Wisconsin State Statutes was approved and published. The first Laboratory Superintendent, Charles M. Wilson, was hired to establish a laboratory in the Capitol Building in Madison. Shortly thereafter, the Madison Laboratory was relocated to the University of Wisconsin Madison campus and finally to University Avenue. Subsequently, a second full-service laboratory was opened in 1975 in New Berlin to serve the eight county Milwaukee metropolitan areas. In 1991, a third laboratory was opened with limited services in Wausau to provide service to the forty northern counties of Wisconsin. Despite it’s humble beginnings, today the WSCL employs approximately over 180 forensic scientists, laboratory technicians, and management, is composed of four distinct bureaus and provides forensic testing for all in Wisconsin’s 72 counties.


Wisconsin: "Forward"


In 2019, the WSCL was reorganized within the Wisconsin Department of Justice (DOJ) to create the Division of Forensic Sciences. The reorganization reaffirmed the commitment that the WSCL is not only performing the high quality analysis it is known for, but also is providing objective scientific analysis. This reorganization was part of a large national conversation with regards to the importance of the credibility of forensic science practices which were outline in the 2009 National Research Council paper “Strengthening Forensic Science in the United States: A Path Forward”. Per the report recommendations “…forensic scientists should function independently of law enforcement administrators. The best science is conducted in a scientific setting as opposed to a law enforcement setting.” From this reorganization in 2019, the WSCL has undergone a transformative period that will pivot DFS into the future via personnel, a Quality and Crime Scene Bureau, new buildings, updated equipment and more engagement and presence with national forensic science standards development and working groups.
