she just happened to be in the wrong place at the wrong time. >> despite the evidence against him, woloson pleaded not guilty. in march of 2006, 25 years after susan's murder, daniel woloson was convicted of first-degree murder and sentenced to 40 years in prison. the university has now built a well-lighted pedestrian overpass so students no longer have to walk through the overgrown dirt path where susan was abducted and murdered. it was named in susan's honor. >> my wife had made the comment, she said, you know, i wonder how much it costs to have one of these overpasses built. and i said, i'll tell you what it costs. it costs one human life. >> that's why we do what we do, you know, to bring justice to these families, so the families deserve a lot of credit, as well. they're the people who push us along the way.
