Donna Mraz Murder
On July 2, 1982, 19-year-old Donna Mraz was stabbed repeatedly behind Camp Randall Stadium. Mraz was on her way home from State Street, where she earned tuition money as a waitress. The killer left behind her money, paycheck, and keys, and there was no indication of sexual assault. Lt. Gary Moore of UW Police told WICS TV, “She never regained consciousness. For all intents and purposes, the young lady was dead when she hit the ground." With no witnesses or motive, investigators were again stumped.

Two years afterward, Donna's body was exhumed to compare her teeth with bite marks of a possible suspect in prisen. No arrest was made and the suspect later died.
