Homicide investigators have launched a new project that aims to bring closure to Wisconsin cold cases through the use of playing cards. Some of the cases are more than 50 years old. One case included in the program is the Madison disappearance and slaying of University of Wisconsin-Whitewater student Kelly Nolan.
Among the unsolved murders of UW-Madison students are those of Brittany Zimmermann (2008), Donna Mraz (1982), and Christine Rothschild (1968).
