Today at the MOCIC conference, a Cybergenetics analyst will present the case of State of Wisconsin v. David Kahl, a cold case involving the 2008 murder of University of Wisconsin–Madison student Brittany Zimmermann.
DNA recovered from Zimmermann’s clothing produced complex mixtures that were inconclusive through manual interpretation because of low DNA amounts and multiple contributors. TrueAllele® analyzed the same data and produced match statistics supporting an association with Kahl.
Kahl later pleaded guilty to first-degree homicide and was sentenced to life without parole.
We look forward to sharing how advanced DNA interpretation helped provide answers in this long-unsolved case.
