WITNESS HELD IN MADISON HOMICIDE
Tuesday, April 22nd, 2008 -- 12:07 PM
A convicted sex offender has been jailed on a probation hold and is considered a material witness in the death of a University of Wisconsin-Madison student from Marshfield.Court documents show David Kahl told police he broke into a home near 21-year-old Brittany Sue Zimmermann's apartment on the day she was killed, and that he knew two homeless men who were running scams and breaking into houses.
WKOW says he also helped police develop a sketch of 1 of the men. The records say he's being treated by police as a material witness, not a suspect.
Zimmermann's fiance found her body April second in their first-floor, off-campus apartment several blocks from the state Capitol.
Investigators have said Zimmermann's door was forced open.
Computerized state court records show his record includes a second-degree sexual assault conviction in a 1993 case where he pleaded no contest and was sentenced to a year in prison.
