Evidence Submission Information
The Wisconsin State Crime Laboratory Bureau (WSCLB) is part of the Division of Law Enforcement Services within the Wisconsin Department of Justice. To support the state, there are three separate service areas: Madison, Milwaukee, and Wausau. Both the Milwaukee and Madison laboratories are full service laboratories providing DNA Analysis while the Wausau laboratory offers limited services at this time. In total, there are ten disciplines practiced at varying levels throughout the state. The service of questioned documents and handwriting analysis as well as tire track impression are no longer provided by the WSCLB.
Services at the WSCLB are available without charge to all authorized submitters. By extension, this includes a member of an authorized agency acting within the scope of their employment. If you are uncertain if you are an authorized submitter please contact the WSCLB.
The WSCLB reserves the right to and may decline any matter that does not involve a felony charge. Whether or not it ultimately accepts a case, the WSCLB is available for consultation. If in doubt, criminal justice providers are urged to contact the WSCLB for advice. The WSCLB is open Monday through Friday, 7:45 am to 4:30 pm, except federal holidays. After-hour services are available via crime scene response teams dispatched from the Madison, Milwaukee, and Wausau Crime Laboratories.
Evidence Submission Information for Criminal Defense
Upon court order, the services of the WSCLB are available at no cost to a defendant in a felony action. Results are confidential to the defense. Often, the items to be examined are in the custody of a police agency. While the agency may be directed to act as courier to deliver and retrieve items after analysis, results will not be discussed with them.
The WSCLB does not provide services for civil cases.
