Prosecutors in Dane County say no charges will be filed in a deadly bus crash in Madison. A 58-year-old University of Wisconsin-Madison librarian was killed June 22 when she was hit by the Metro bus turning a corner. The district attorney?s office reviewed reports from police, reconstruction investigators and the state lab in making the determination. Prosecutors say the bus had a significant blind spot that prevented the driver from seeing Maureen Grant in the pedestrian crosswalk.
