Four years ago, the Zimmermann family experienced a tragedy when they lost their daughter, Brittany, a University of Wisconsin-Madison student, in a horrific and still unsolved murder. According to event treasurer Beverly Otis, approximately 280 runners participated Saturday in the annual 5K ?Brittany Run,? which was hosted by the Zimmermann family. Although the goal of the race is to increase crime awareness, the money raised from the participation fee supports a private volunteer organization called Madison Area Crime Stoppers, which uses funds to pay for tips that aid police investigations.
