Probabilistic Genotyping [STRmixTM] Training
In 2020, the Division of Forensic Science (DFS) implemented a new DNA interpretation technology, Probabilistic Genotyping [i.e. STRmix™]. Probabilistic genotyping is a method of evaluating DNA results that utilizes more information from DNA profiles and advanced computing methods to assist the DNA Analyst in the interpretation of forensic DNA typing results. As a tool, probabilistic genotyping provides statistical weight in the form of a likelihood ratio to generated conclusions. To assist with this transition in technology, the DFS, with the assistance of the District Attorney’s Office, offered a webinar training series for law professionals working in the criminal court setting.
This webinar series provides awareness and understanding education related to the implementation of probabilistic genotyping [STRmix] technology. The recorded sessions review the statistical methods and provide a basic overview of probabilistic genotyping as well as offer an introduction to associated DFS procedures and reporting. Impacts of the new technology on investigations prior to and through court proceedings are also discussed. Training includes examples of effective court questions and open discussion with Forensic DNA Analysts from the DFS. The archived webinar series is available to WILENET Users here.

Crime Scene Processing Course
The Crime Scene Processing (CSP) course covers the detection, documentation, preservation, collection, and preparation for the submission of physical evidence to the State Crime Laboratories for Law Enforcement throughout the state. Instructors from the Crime Laboratories will also provide lectures and hands-on training in aspects of photography, fingerprints, footwear, firearms/toolmarks, trace evidence, and DNA. The course will culminate with a crime scene exercise that will have the students utilize the skills they have learned throughout the week.
Any full-time employee (sworn or not) of a local, county, state or tribal law enforcement agency within the State of Wisconsin whose duties include, or will include, crime scene evidence is eligible to apply. The Crime Laboratory accepts all applications for attendance, however, not all applicants will be offered a seat in the class. As seats are not determined on a first come, first serve basis, all applicants will undergo a selection process. Notification of status in the course will be sent four weeks prior to the course.
As part of the registration process a letter of recommendation from a high-ranking officer within your agency is required. Please have this available when registering to attend the course.
