The Brittany Zimmerman murder is back in the news. A newly unsealed search warrant confirms police did get a tentative DNA match tying a 50-year-old man to the scene of the crime. Zimmermann was found stabbed to death in her off-campus apartment in downtown Madison in April of 2008.
David Kahl has also been identified as a person seen going door to door in Zimmerman’s neighborhood asking for money to repair a non-existent tire.
Kahl is currently in prison for a 7th offense OWI. A friend of his, who is in prison, also claims Kahl confessed to him that he killed the 21-year-old UW student. A DNA profile taken from the shirt worn by Zimmerman hit on a DNA profile of Kahl, although there’s no indication of how strong of a match it is.
Zimmerman’s parents, Kevin and Jean Zimmermann of Marshfield, announced in Februray that a DNA match had been made, although they did not name the individual who was matched.
